“Tiny” amounts of crude oil on the sea surface can damage seabird feathers, according to a University College Cork (UCC) study.

Oil less than one percent of the thickness of a hair can cause harm, researchers from UCC’s Marine Ecology Group state.

The team collected feathers from Manx shearwaters, a seabird species thought to be at-risk from oil pollution, and examined them to see how quickly water would pass through after exposure to increasing concentrations of oil.

Feathers were also assessed under high-powered microscopes to examine structural changes after contamination, they state.

The research found that really thin oil sheens, between 0.1 and 3 micrometres in thickness, were “enough to have a significant effect on feather structure and impacted waterproofing”.

Other studies have shown that seabirds exposed to oil are more likely to become waterlogged, cold, and less buoyant.

Environmental disasters such as the Exxon Valdez and Sea Empress spills have released unrefined oil, or crude oil, into the sea in huge volumes.

Crude oil is also routinely released into the environment in moderate volumes due to extraction and transport activity, the researchers note.

“Chronic small-scale oil pollution is commonly overlooked in the marine environment, though it has been shown to have serious implications for the fitness and survival of seabirds,” Emma Murphy, lead author of the study, says.

“This study examined one species, but the results can be extended to other species that rely on waterproofing to stay healthy when at sea for long periods,” she says.

The research is published in the journal Open Science.

A short film featuring the views of local communities who make a living from the sea is set to be launched in Kerry this week. Fair Seas, a coalition of Ireland’s leading environmental non-governmental organisations and networks, created the 12-minute feature to explore how changes to how marine areas are protected would affect the people living nearby.

The film hears voices in coastal communities, including fishers, eco-tourism operators and biologists. Exploring local stories, hopes and fears, it delves into how Marine Protected Areas might offer new means to conserve the incredible marine life that has supported these communities for centuries.

Fair Seas is calling on the Government to designate a minimum of 30% of Irish waters as a network of effective and well-managed Marine Protected Areas by 2030. Marine Protected Areas (MPAs) are areas of our seas and coasts legally protected from activities that damage the habitats, wildlife and natural processes. Currently, just 2% of Irish waters are protected.

The group published a report in June identifying 16 ‘Areas of Interest’ for MPA designation in Irish waters, including one area stretching along the Kerry coastline from Kenmare Bay as far as Loop Head in Clare.

Tralee and Dingle Bays are breeding areas for several threatened shark, ray and skate species. This is an important area for whales, dolphins and porpoises with islands and archipelagos that skirt the peninsulas of Kerry, some of Ireland’s most prominent seabird breeding sites.

Aoife O’ Mahony, Campaign Manager for Fair Seas said, “Kerry has a fascinating marine environment where large numbers of dolphins, humpback whales and minke whales can be seen. It’s also home to significant colonies of puffins and gannets. It is in everyone's interest that these areas are conserved and protected. We’ve started the conversations around Marine Protected Areas as significant progress is needed if Ireland is to reach the 30% targets set down by Europe by 2030. The people who rely on our oceans are central to this, so we spoke to fishers, anglers, divers, eco-tourism operators and locals to get their views and opinions.”

Lucy Hunt, Founder of Sea Synergy is featured in the film, (and features in this podcast on Afloat here) she added, “Seeing integrated coastal zone management and marine protected areas that includes all stakeholders, including the ocean and all the life it supports, is vital to maintain sustainable and resilient coastal communities. Kerry has amazing marine ecosystems; it’s not just home to marine mammals and wildlife but has habitats that can contribute to mitigating climate change, some of which are yet to be explored or mapped. More research is important, but we know enough to start the protection process. Stakeholder engagement, resource provision and policy action is the next step.”

The film will be officially launched at 7.00 pm on Friday, October 7th as part of the Iveragh Learning Landscapes weekend at Tech Amergin, Waterville. Tickets for the weekend of walks, talks and workshops are €5 and are available online 

Fair Seas marine policy officer Dr Donal Griffin will be taking part in the Climate Conversations panel on Saturday afternoon alongside marine biologist and TV host Danni Washington, Lucy Hunt Founder of Sea Synergy and Vincent Hyland of Wild Derrynane.

This film was part funded by the Networking and Marine Research Communications Awards, funded by the Marine Institute under the Marine Research Programme with the support of the Irish Government.

It was produced by Swimming Head Productions, an award-winning team specialising in quick-fire documentaries with a focus on heritage, science and the natural world.

Coastwatch has appealed for volunteers to join its annual autumn shore survey, which runs from mid-September to mid-October.

“This is now one of the longest standing citizen science projects in Ireland,” Coastwatch founder Karin Dubsky says.

” It’s a basic eco-audit of the shore carried out around low tide between Sept 15th and Oct 15th,” she says.

“You can go out as a group, divide tasks between you and cover long dune stretches in one sweep, having fun at the same time; or you go in pairs or alone to a favourite quiet spot,” Dubsky explains.

“Either way, you are carefully observing, testing any streams you might cross and then report back on the state of that shore,” she says.

The annual citizen science audit started in 1987, with The Irish Times publishing a pull-out survey page.

It is now largely online with an accessible GIS map to choose sites to survey once between Sept 15th and Oct 15th, Dubsky says.

Volunteers book their site on an interactive map and download materials, or ask Coastwatch for these, Dubsky says.

They can “zig-zag” their chosen 500m of shore around low tide to record and report their findings from erosion to stream water quality, using test kits, and record key animals and plants along with waste and litter, she explains.

Micro litter can also be recorded, using a Coastwatch developed app, Dubsky says.

The first results will be presented in early December at Trinity College Dublin.

Dubsky says training is provided for new volunteers, and regional coordinators are planning joint survey events to cover some areas really well.

‘This year, we focus on the quality of small streams, seagrass and on litter which would be better addressed by prevention and law than by clean-ups,” Michael Walsh of the Coastwatch team says.

“Small coastal streams may not look impressive but can host fish like seatrout and eel,” John Cullen, one of the Coastwatch team scientists, explains.

“In a training session last week, we checked a tiny stream flowing through Tintern Abbey walled gardens, Co Wexford”, Dubsky says.

“It was full of life and young sea trout are regularly observed here. We would love to mark such streams with big smiley faces on our maps and help restore other streams which we find in a dead or sad state,” she says.

‘With bird flu hitting many seabird colonies, we are now also asking for photographs and to report dead birds to DAFM using the Avian Flu reporting app or hotline so they can pick up and test for flu,” she says.

This will be the third year of recording COVID-related litter, and the first full year since government restrictions on a range of single-use plastics (SUP) has been implemented.

A three-year snapshot of Covid-related litter and SUP plastic will be published in December, she said.

All materials are on the Coastwatch website www.coastwatch.org or available from coordinators.

The West Coast of Ireland is the first place in the world where the annual reproductive behaviour of basking sharks has been seen.

“It is astonishing that this wonder of the natural world has remained hidden for so long,” according to Professor David Sims, Senior Research Fellow at the University of Southampton and lead author of a study carried out by biologists from the Marine Biological Association and the Irish Basking Shark Group.

It has revealed “the global importance of the West Coast of Ireland for the endangered species.”

Circling formations have been documented on a few occasions over the past 40 years in the North-West Atlantic off Canada and the USA. But although basking sharks are often seen filter-feeding plankton in the UK and Irish coastal waters during the summer, the circling formations were rarely seen. Until now, scientists could not explain the behaviour.

Using underwater cameras and aerial drones off County Clare from 2016 to 2021, scientists got video footage of 19 circling groups. Each comprised between 6 and 23 sharks swimming slowly at the surface, with others deeper down.

“This research has shown the importance of Irish waters,” says Dr Simon Berrow of the Atlantic Technological University, Galway and the Irish Basking Shark Group, who co-led the research: “How usually solitary basking sharks find a mate in the ocean’s expanse has been an enduring mystery. Our discovery of these basking shark grounds in our coastal waters makes it more urgent that this species gains protection in Irish waters from potential threats, such as collisions with marine traffic and the impact of offshore renewables.”

Legislation to protect basking sharks in Irish waters was drafted this year, although they are protected in many parts of the world. It remains to be signed into law.

Young people with an interest in biodiversity loss in marine, freshwater and terrestrial environments have been invited to apply to join Ireland’s first national children and young people’s assembly dedicated to the issue.

The new Children and Young People’s Assembly aims to inform the national Citizens’ Assembly on Biodiversity Loss which is sitting this year.

A total of 35 children and young people will be selected randomly across Ireland as assembly members, with applications to join closing on September 18th.

However, all young people aged up to 17 years are invited to submit their views and ideas on biodiversity loss on sea and land throughout the month of September on a new website cyp-biodiversity.ie

The Citizens’ Assembly on Biodiversity Loss comprises 99 randomly-selected adult members of the public, who are aged 18 and over, and an independent chairperson.

It has been tasked by the Oireachtas with examining how the State can improve its response to the issue of biodiversity loss.

It believes children and young people also have the right to have their say, as biodiversity loss poses a significant threat to children’s right to a healthy, safe environment.

The Children and Young People’s Assembly is being designed by an intergenerational group, comprising a young advisory team and an independent research consortium.

The young advisory team involves nine children and young people from across Ireland, aged between eight and 16 years.

The research consortium includes experts in children’s participation, deliberative democracy, and biodiversity from Dublin City University *(DCU), University College Cork (UCC), and “terre des homes”, an international organisation with a focus on children’s environmental rights.

Elsie (8), a young advisor from Co Tipperary has said she believes it is “important that children and young people like us can have our say because we don’t usually get to be involved in things that adults do and we have lots of interesting things to say.”

Amhairghin (15), a young advisor from Co Donegal and Co Down said that “diversity is the key to this process”.

“If we don’t have ideas coming from every aspect of life, we’ll be stuck with a rigid, one sided argument. It’s also really important that young people deliver these arguments as we are the future. It’s time that we saw the action that is needed,” she has said.

Dr Diarmuid Torney, research consortium lead and an associate professor at DCU’s School of Law and Government, said that Ireland has “developed a strong reputation over the past decade in the inclusion of the voices of the adult population in policymaking through citizens’ assemblies”.

“Through this project, we aim to build on this reputation by creating a robust process to include the voices of children and young people in decision-making on the critical topic of biodiversity loss,”he said.

Katie Reid, research consortium member and children’s environmental rights and participation officer with “terre des homes”, said she has supported children’s participation in Scotland’s Climate Assembly, which was the first citizens’ assembly to involve under 16-year-olds directly.

“I experienced how deliberative democratic processes can be enriched by taking an intergenerational approach that includes our youngest citizens’ views and ideas,” Reid said.

Dr Clodagh Harris, research consortium member and senior lecturer in UCC’s Department of Government and Politics, quoted a native American proverb – “ we do not inherit the Earth from our ancestors; we borrow it from our children”.

“Decisions made (or not made) on biodiversity loss today will have irreversible consequences for children and young people. It is essential that their views are heard,” Harris noted.

Applications to become an assembly member can be submitted online here

The closing date for applications is Sunday, September 18th. Those randomly selected will need to be available to attend two assembly meetings, on October 7th to 9th in Glencree, Co Wicklow, and on October 21st to 23rd in Killarney, Co Kerry.

An open submissions portal has been created for other children and young people to contribute to the assembly, which will remain open until September 30th.

Submissions can be written, artwork, video clips or photographs, and a short explanatory film is on this link

Thousands of volunteers answered Clean Coasts and National Spring Clean joint call-to-action to organise a clean-up to protect our ocean today, June 8th. 

Last May, Irish environmental charity Clean Coasts joined forces with National Spring Clean, to provide communities around Ireland with free clean-up kits to host a clean-up during the week around World Ocean Day.

World Ocean Day is celebrated annually on June 8th to highlight the important role the ocean has for our life and the planet. In 2022, the focus will once more be on the 30x30 campaign: to create a healthy ocean with abundant wildlife and to stabilize the climate, it is critical that 30% of our planet’s lands, waters, and ocean are protected by 2030.

One of the issues affecting our ocean is marine litter which has become a global problem for both humans and marine life. However, communities around Ireland have demonstrated their desire to be part of the solution by taking part in several beach cleaning and clean-up calls to action.

Statistics show that the number one cause of marine litter is litter dropped in towns and cities. Building on the success of the Spring Clean 22 campaign, which took place in the month of April and saw 500,000 volunteers organising over 5,600 clean-ups, the National Spring Clean programme is joining Clean Coasts this year in supporting these communities around Ireland.

Sinead McCoy, Coastal Communities Manager said: “We were so overwhelmed with the support received from the public. In under 72 hours over 230 clean-ups had already registered on the Clean Coasts website. Now over 4,000 volunteers are set to take action for World Ocean Day by organising or joining a clean-up event around Ireland.”

Volunteers who didn’t manage to secure a clean-up kit can still take action by joining an existing clean-up, a list of which can be found on the Clean Coasts website.

World Ocean Day events are happening in the context of a very few busy months for the organisation, which saw other initiatives to protect and learn more about the ocean being launched recently. These initiatives included the launch of our Enjoy and Protect campaign and several events, such as SUP clean-ups or surf lessons followed by a #2minutebeachclean around all the coast of Ireland. In addition to that, Clean Coasts joined Galway City Council for a #TeamSeas clean-up of the Claddagh Basin and lower Eglington Canal, where over 2 tonnes of litter were removed from an area that would normally be hard to clean. Other events include the release of two marine biodiversity directories, the launch of our Love Your Coast Photography Competition, marram grass planting events and more.

Team Seas Clean up

Finally, to celebrate World Ocean Day and following the launch of two Marine Biodiversity directories last month, yesterday Clean Coasts has also issued a fourth Enjoy and Protect guide about wildlife photography, specifically designed not just for amateur photographers wishing to enter the Love Your Coast Photography competition, but also for the general public who wish to capture the beauty of our coastline while doing something to protect it. [See editor's notes for details]

In 2021, the initiative changed its name from “World Oceans Day” to “World Ocean Day”. By dropping the “s”, its organisers wanted to highlight the fact that we are all connected by a large ocean. This shared ocean supports all life on the planet, by producing most of the oxygen we breathe and regulating climate. No matter where we live, we all depend on the ocean to survive.

This means that each piece of marine litter removed from a beach, river, lake, park or street in Ireland, will have a positive impact on a global scale.

Other Clean Coasts events and initiatives this summer 

Enjoy and Protect (guides) 

With the ‘Enjoy and Protect’ campaign, Clean Coasts are asking people to enjoy and celebrate our stunning coastline, beautiful beaches, epic cliffs and all outdoor areas, but also to protect these natural treasures. Get out and make the most of Ireland’s wonderful coast, but also do your part to preserve our marine environment and keep it safe and beautiful for future generations to enjoy too, with simple actions and small lifestyle changes. More info here.

Enjoy and Protect (events)

To celebrate the launch of the ‘Enjoy and Protect’ campaign, we have been hosting a series of events in Ireland, including a SUP clean-up of the Dun Laoghaire Harbour and a Surf Lesson and #2minutebeachclean in Strandhill, co. Sligo.

Love Your Coast

The 13th Clean Coasts’ Love Your Coast photography competition is now open for entries. Amateur photographers were invited to capture the uniqueness of our coastal communities, environments, or waterways and enter their best shots over the past couple of months. 

There is a prize fund of €5,000, up for grabs across five categories: Coastal Heritage, Coastal Landscape, People & the Coast, Wildlife & the Coast and Creativity and the Coast. More info here. 

#TeamSeas

As part of Ocean Conservancy #TeamSeas Project, Clean Coasts and Galway City Council partnered up to support a clean-up of the Claddagh Basin and lower Eglington Canal, where over 2 tonnes of litter were removed from an area that would normally be hard to clean.

As part of this project, the Lower Eglinton Canal and Claddagh Basin were drained, and litter was removed by a professional contractor. This has removed a significant amount of litter from our waterways and stopped it from herebreaking down further. 

Love Your Beach Week

Clean Coasts are delighted to once more partner with Galway City Council for Love Your Beach Week, which will launch on June 8th.

The week entails a series of beach cleans and other events, such as workshops, talks on biodiversity and climate change, music and beach volley. More info here. 

Cork Harbour Festival 

Cork Harbour Festival returns this June 3-13 with over 50 amazing events in 15 beautiful locations across Cork City & Harbour, to celebrate Cork’s unique maritime heritage as the second largest natural harbour in the world.

For this event, Clean Coasts will join forces with Cork County and City Councils and Subowti for a Kayak & SUP River Clean Up. More info here 

Wild Roots

Last weekend, June 3 – 5, Clean Coasts promoted simple actions to protect our environment at Wild Roots festival in Sligo. Wild Roots is an art, music and adventure festival taking place for the first time set in the stunning Hazelwood area, protected by ancient woodland and close to the tranquil waters of Lough Gill. As well as performances from international and local acts, there was stand up paddle boarding, kayak tours, sailing and boat tours on Lough Gill. Clean Coasts were at the shop street area talking about the Think Before You Flush campaign that we operate in partnership with Irish Water, as well as ways to get involved with the Clean Coasts programme. We had games, prizes, #2minutebeachclean and information on protecting our environment.

Brown Thomas Corporate volunteering

Earlier in June, Clean Coasts met the Brown Thomas team for a series of beach cleans in four different locations around Ireland as part of the organisation’s corporate volunteering programme.

Clean ups took place on Bull Island, co. Dublin, Galway City, Limerick City and Garretstown Beach, co. Cork, and participants removed a total of almost 50 kg of marine litter from the Irish Coast.

PayPal

As one of this year’s chosen charities of PayPal, Clean Coasts has been working with employees from PayPal to develop a coastal programme in Co. Louth. The programme includes marram grass planting to combat erosion, family beach cleans event, beach information and interactive hubs, and looking into an online erosion monitoring model that can be used on the Clean Coasts website. There has also been cross-collaboration with local registered Clean Coasts groups in Co. Louth including Cooley Community Alert and Costa Aláinn Termonfeckin.

Marine Biodiversity Directories

To celebrate National Biodiversity Week in May, Clean Coasts released two marine biodiversity directories.

The Marine Zones and Habitats directory explores these zones and habitats a little further, from above the high tide line, right out to the edge of the continental shelf. Ireland’s coastline and marine environment is teeming with life, playing host to 24 species of whales and dolphins, 35 species of sharks, 2 species of seal, 24 species of seabirds, over 250 species of marine plants and hundreds of species of fish and invertebrates. The Marine Species directory talks about some of these species, where they can be found and more. More info here.

Wexford marram grass planting

Wexford County Council have made steps to combat erosion at some coastal beaches, including Morriscastle Strand. The dune beside the entrance to the beach has been suffering from quite severe erosion, so the Council arranged for chestnut pail fencing to be erected in sections that would help keep off people from any planting that could happen. Clean Coasts teamed up with Wexford County Council to do marram grass planting sessions within these fenced areas. The first day was with locals of Kilmuckridge and surrounding areas on 30th April, and the second day was with students from Colaiste an Atha, Kilmuckridge, on 19th May which the day before Morriscastle Strand received the 2022 Blue Flag Award.

School coastal education and action

Bettystown, Co. Meath – Teaming up with Bettystown Tidy Towns, Clean Coasts engaged with local schools around the local area to educate with marine topics and tackle marine litter. Clean Coasts facilitated workshops and beach cleans at Bettystown beach with these school groups: Drogheda Grammar School on 9th March, Colaiste na hInse on 16th March, Malta Services Drogheda on 29th March, Bettystown Youth Reach on 30th March, English Language Institute on 6th April, St. Oliver’s Community College on 27th April, and Scoil Oilibheir Naofa on 31st May. There are upcoming days with Slane N.S. and also a Clean Coasts stand for World Ocean Day festival on the 11th June.

Cooley, Co. Louth – Teaming up with Cooley Community Alert, Clean Coasts engaged with local schools around the local area to educate with marine topics and tackle marine litter. Clean Coasts facilitated workshops and beach cleans with Scoil Naomh Loran (Omeath) on 7th March, Rathcor N.S. (near Templetown) on 8th April, Knockbridge N.S. (Blackrock) on 4th May, and Muchgrange N.S. (Templetown) on 5th May.

A “Clean Oceans” fishing gear retirement scheme has been announced by Minister for Marine Charlie McConalogue to mark World Oceans Day.

The project, which is aimed at collecting old and damaged fishing gear, is to take place this autumn and is being led by Bord Iascaigh Mhara (BIM).

The “Clean Oceans” initiative was established in 2019 to address the growing problem of plastics and other waste in the world’s oceans.

Almost 600 tonnes of waste has been hauled up in nets by fishers and by the wider Irish seafood industry during a series of pier and shore clean-ups, according to BIM. The initiative is supported by the European Maritime Fisheries and Aquaculture Fund.

“Protecting Ireland’s marine environment means protecting the marine habitat and protecting Ireland’s coastal communities today, and for future generations,” Mr McConalogue said.

“The livelihoods of those who live and work in these communities depend on their working environment being pristine. I am greatly encouraged by the huge efforts being made by fishers, and by the wider Irish seafood industry as part of the “Clean Oceans” initiative,”he said.

“This is an industry which is demonstrating the positive impact that is being made through working together to actively address the serious problem of plastics in our oceans,” he said.

The “Clean Oceans Initiative Fishing Gear Retirement Scheme”, as it is called, is being piloted in Ros-a-Mhíl, Co Galway later this year.

Fishers from the Ros-a-Mhíl fleet are being invited to dispose of their old and damaged gear as part of a free drop-off service at the pier. The fishing gear will then be recycled, upcycled, or disposed of responsibly, BIM says.

Vessel owners will be asked to register details of the materials they drop off to record their origin, and to allow BIM to track how they are used in the future.

BIM chief executive Jim O’Toole said that “genuine efforts are being made by the Irish seafood industry to do what it can to address the issue”.

He said collaboration across the industry and with the wider marine sector has been critical to the success of the “Clean Oceans” initiative.

The "underwater treasure" around over 3,000 km of Irish coastline is the theme of three talks hosted by Galway Atlantaquaria to mark World Oceans Day.

As Dr Noirín Burke of Galway Atlantaquaria says, Ireland can “boast an incredible range of different underwater environments and a diversity of marine life that is still mostly unknown - although 40% of the Irish population lives within five kilometres of the sea”.

“There is probably no better day to celebrate this underwater treasure than World Oceans Day,” she says.

The June 8th date was designated by the United Nations to “acknowledge our world’s shared ocean and our personal connection to the sea, as well as to raise awareness about the crucial role the ocean plays in our lives and the important ways people can help protect it”, she says.

Three speakers booked by Galway Atlantaquria will offer three very different perspectives of marine management, citizen science and biodiscovery - all with the same focus of conservation.

Tony O’Callaghan, will give an overview of the activities carried on by Seasearch Ireland, which he co-ordinates.

Seasearch involves divers and snorkelers who have an interest in what they’re seeing underwater, want to learn more and want to help protect the marine environment around the coasts of Ireland and Britain.

Volunteers involved in its citizen science projects map out various types of sea bed found in the near-shore zone around the island to establish “the richest sites for marine life, the sites where there are problems and the sites which need protection”.

Also speaking is Sibéal Regan, education and outreach officer with the Irish Whale and Dolphin Group (IWDG).

The IWDG is also involved in the Fair Seas campaign, initiated by a number of leading national environmental organisations and networks to campaign for rapid expansion of marine protected areas in Irish Waters, with a target of at least 10% of Irish waters to be designated as “fully protected' by 2025 and at least 30% by 2030.

Regan will focus on the new report, entitled “Revitalising Our Seas, Identifying Areas of Interest for Marine Protected Area Designation in Irish Waters”, which Fair Seas will release on World Oceans Day.

The final speaker is Sam Afoullouss, PhD student at NUI Galway’s marine biodiscovery laboratory.

He will describe the variety of underwater environments that can be found around Ireland, from the rich kelp forests in shallow waters to the flourishing coral gardens in the ocean’s darkest depths, and will speak about a “still untapped medicinal potential”.

Having given a highly successful TED talk at the end of last year, Afoullouss will “dive into the science behind natural remedies”.

He will also explain why the ocean's “great and still largely unexplored biodiversity is ideal for deriving and inspiring future treatments, but only if we protect its waters and life”.

The marine talks are free, from 7pm to 8.30pm on Wednesday June 8th at Galway Atlantaquaria, and booking is essential on https://bit.ly/396PGnt

The harmless-looking goldfish is so voracious that attempting to save its life by releasing it into the wild could be “catastrophic” for native biodiversity, a new study suggests.

A study by Queen’s University Belfast (QUB) scientists assessed the ecological impact of the pet fish if released into the wild by comparing it to the white cloud mountain minnow.

The goldfish and white cloud mountain minnow are the two most commonly traded fish species in Northern Ireland.

The goldfish has established non-native populations around the world since it was “domesticated” a thousand years ago.

By contrast, the white cloud mountain minnow has a limited invasion history to date, the QUB researchers point out.

This study published in NeoBiota – a website for the European Group on Biological Invasions - showed goldfish to be “voracious, consuming much more than the white cloud mountain minnow or native species”.

“In terms of behaviour patterns, goldfish were also found to be much braver, a trait linked with invasive spread,” the study says.

Lead author Dr James Dickey from the QUB School of Biological Sciences said the research “suggests that goldfish pose a triple threat”.

“Not only are they readily available, but they combine insatiable appetites with bold behaviour,” he said.

“While northern European climates are often a barrier to non-native species surviving in the wild, goldfish are known to be tolerant to such conditions, and could pose a real threat to native biodiversity in rivers and lakes, eating up the resources that other species depend on,” he said.

“Our research highlights that goldfish are high risk, but we hope that the methods developed here can be used to assess others in the pet trade across Ireland and further afield,” Dr Dickey said.

“Readily available species are most likely to be released, so limiting the availability of potentially impactful ones - alongside better education of pet owners - is a solution to preventing damaging invaders establishing in the future,” he said.

The QUB research was funded by the Alexander von Humboldt Foundation, Inland Fisheries Ireland and the Northern Ireland Department of Agriculture, Environment and Rural Affairs (DAERA)

The findings were presented at the International Conference on Aquatic Invasive Species in Oostende, Belgium along with a range of other leading research from QUB on alien species.

A newly formed Irish environmental coalition says it is “demanding” a fifteen-fold increase in Ireland’s marine protected areas (MPAs).

The Fair Seas campaign wants at least 10 per cent of Irish waters to be designated as “fully protected” by 2025, and “at least” 30 per cent by 2030.

“Today Ireland’s MPA coverage is at a mere 2.13% lagging behind even our closest neighbours in Scotland at 37%,” the campaign says.

“Ireland has not met its previous target of 10% protection by 2020,” it says warning that “Fair Seas will hold the government to account so it does not miss its upcoming targets”.

“Ireland’s maritime area is seven times the size of our landmass and is home to spectacular wildlife including endangered basking sharks, humpback whales, blue whales, otters, seals, puffins and even deep-sea coral reefs,” the campaign says.

It aims to see Ireland becoming a “world leader in marine protection, giving our species, habitats and coastal communities the opportunity to thrive”.

MPAs, which give legal protection to the conservation of species and habitats, are a “vital tool” in improving ocean health, it says.

The Fair Seas campaign says it will publish its first expert report, underpinned by scientific data, this summer, and this will identify where it believes MPAs should be designated.

Legislation for the designation and management of MPAs is currently being drafted and the Heads of Bill is expected before Government in December 2022.

“In January 2022 Ireland showed its passion for the ocean by speaking out against Russian missile testing,” Fair Seas campaign manager Aoife O’Mahony said.

“Voices from the fishing industry, government, environmental groups and the public were all echoing the need to protect our marine biodiversity and commercially important fish stocks. Fair Seas is calling on those same voices to ask the Irish government to follow up and secure a network of effective well-managed MPAs,” she said.

“Fair Seas is a new and inclusive approach to environmental campaigning,” Irish Whale and Dolphin Group (IWDG) co-ordinator Dr Simon Berrow said.

General Information on using Waterways Ireland inland navigations

Safety on the Water

All users of the navigations are strongly recommended to make themselves aware of safety on the water for whatever activity they are involved in and to read the advice offered by the various governing bodies and by:

The Dept. of Transport, Ireland: www.gov.ie/transport and The Maritime and Coastguard Agency, UK, The RNLI – Water Safety Ireland for information in terms of drowning prevention and water safety.

Registration of Vessels

All vessels using the Shannon Navigation, which includes the Shannon-Erne Waterways and the Erne System must be registered with Waterways Ireland. Only open undecked boats with an engine of 15 horsepower or less on the Shannon Navigation, and vessels of 10 horsepower or less on the Erne System, are exempt. Registration is free of charge.

Craft registration should be completed online at: https://www.waterwaysireland.org/online-services/craft-registration

Permits for use of the Grand and Royal Canals and the Barrow Navigation

All vessels using the Grand and Royal Canals and the Barrow Navigation must display appropriate valid Permit(s) i.e A Combined Mooring and Passage Permit (€126) and if not intending to move every five days, an Extended Mooring Permit (€152).

Permit applications should be completed online at: https://www.waterwaysireland.org/online-services/canal-permits

Passage on the Royal and Grand Canals – Dublin Area

For boat passage through the locks east of Lock 12 into / out of Dublin on either the Royal or Grand Canals, Masters are requested to contact the Waterways Ireland Eastern Regional Office (M-F 9.30am-4.30pm) on tel: +353(0)1 868 0148 or email [email protected] prior to making passage in order to plan the necessary lock-keeping assistance arrangements.

On the Grand Canal a minimum of two days notice prior to the planned passage should be given, masters should note that with the exception of pre-arranged events, a maximum of 2 boats per day will be taken through the locks, travelling either east or west.

Movements in or out of the city will be organised by prior arrangement to take place as a single movement in one day. Boaters will be facilitated to travel the system if their passage is considered to be safe by Waterways Ireland and they have the valid permit(s) for mooring and passage.

Newcomen Lifting Bridge

On the Royal Canal two weeks’ notice of bridge passage (Newcomen Lifting Bridge) is required for the pre-set lift date, and lock assistance will then also be arranged. A minimum of 2 boats is required for a bridge lift to go ahead.

Waterways Ireland Eastern Regional Office (Tel: +353(0)1 868 0148 or [email protected] ) is the point of contact for the bridge lift.

A maximum number of boats passing will be implemented to keep to the times given above for the planned lifts (16 for the Sat / Sun lifts & 8 for the weekday lifts). Priority will be given on a first come first served basis.

On day of lift, boaters and passengers must follow guidance from Waterways Ireland staff about sequence of passage under bridge & through Lock 1, and must remain within signed and designated areas.

Events Held on the Waterways

All organised events taking place on the waterways must have the prior approval of Waterways Ireland. This is a twelve week process and application forms must be accompanied with the appropriate insurance, signed indemnity and risk assessment. The application should be completed on the Waterways Ireland events page at :

https://www.waterwaysireland.org/online-services/event-approval

Time Limits on Mooring in Public Harbours

On the Shannon Navigation and the Shannon-Erne Waterway craft may berth in public harbours for five consecutive days or a total of seven days in any one month.

On the Erne System, revised Bye Laws state that: No master or owner shall permit a vessel, boat or any floating or sunken object to remain moored at or in the vicinity of any public mooring, including mooring at any other public mooring within 3 kilometres of that location, for more than 3 consecutive days and shall not moor at that same mooring or any other public mooring within 3 kilometres of that location within the following 3 consecutive days without prior permission by an authorised official.

Winter Mooring on the Shannon Navigation and Shannon Erne Waterway

Winter mooring may be availed of by owners during the period 1 Nov to 31 Mar by prior arrangement and payment of a charge of €63.50 per craft. Craft not availing of Winter Mooring must continue to comply with the “5 Day Rule”. Winter Mooring applications should be completed online at : https://www.waterwaysireland.org/online-services/winter-moorings-booking

Owners should be aware that electricity supply and water supply to public moorings is disconnected for the winter months. This is to protect against frost damage, to reduce running costs and to minimise maintenance requirements during the winter months.

Vessel owners are advised that advance purchasing of electricity on the power bollards leading up to the disconnection date should be minimal. Electricity credit existing on the bollards will not be recoverable after the winter decommissioning date. Both services will be reinstated prior to the commencement of the next boating season.

Smart Cards

Waterways Ireland smart cards are used to operate locks on the Shannon Erne Waterway, to access the service blocks, to use the pump-outs along the navigations, to avail of electrical power at Waterways Ireland jetties.

Berthing in Public Harbours

Masters are reminded of the following:

  • Equip their vessel with mooring lines of appropriate length and strength and only secure their craft to mooring bollards and cleats provided for this purpose.
  • Ensure the available berth is suitable to the length of your vessel, do not overhang the mooring especially on finger moorings on floating pontoon moorings.
  • Ensure mooring lines, electric cables and fresh water hoses do not create a trip hazard on public jetties for others users.
  • Carry sufficient fenders to prevent damage to your own vessel, other vessels and WI property.
  • Allow sufficient space between your vessel and the vessel ahead /astern (c.1m) for fire safety purposes and /or to recover somebody from the water.
  • Do not berth more than two vessels side by side and ensure there is safe access/egress at all times between vessels and onto the harbour itself.
  • Do not berth in such a way to prevent use of harbour safety ladders, slipways or pump-outs.
  • Do not allow the bow of your vessel to overhang the walkway of a floating mooring thus creating a hazard for others with an overhanging anchor or bow fendering.
  • Animals are not allowed to be loose or stray at any time.
  • Harbour and jetty infrastructure such as railings, power pedestals, fresh water taps, electric light poles, safety bollards, ladders etc are not designed for the purpose of mooring craft , they will not bear the strain of a vessel and will be damaged.
  • At Carrybridge on the Erne System, Masters of vessels are not permitted to use stern on mooring. Masters of vessels must use the mooring fingers for mooring of vessels and for embarkation / disembarkation from vessels.

Passenger Vessel Berths

Masters of vessels should not berth on passenger vessel berths where it is indicated that an arrival is imminent. Passenger vessels plying the navigations generally only occupy the berths to embark and disembark passengers and rarely remain on the berths for extended periods or overnight.

Lock Lead-in Jetties

Lead-in jetties adjacent to the upstream and downstream gates at lock chambers are solely for the purpose of craft waiting to use the lock and should not be used for long term berthing.

Vessel Wake

Vessel wake, that is, the wave generated by the passage of the boat through the water, can sometimes be large, powerful and destructive depending on the hull shape and engine power of the vessel. This wake can be detrimental to other users of the navigation when it strikes their craft or inundates the shoreline or riverbank. Masters are requested to frequently look behind and check the effect of their wake / wash particularly when passing moored vessels, on entering harbours and approaching jetties and to be aware of people pursuing other activities such as fishing on the riverbank.

Speed Restriction

A vessel or boat shall not be navigated on the Shannon Navigation at a speed in excess of 5 kph when within 200 metres of a bridge, quay, jetty or wharf, when in a harbour or canal or when passing within 100 metres of a moored vessel or boat.

Vessels navigating the Shannon-Erne Waterway should observe the general 5 kph speed limit which applies along the waterway. This is necessary in order to prevent damage to the banks caused by excessive wash from vessels.

Vessels navigating the Erne System should observe the statutory 5kt / 6mph / 10kph speed limit areas.

A craft on the Royal and Grand canals shall not be navigated at a speed in excess of 6km per hour.

A craft on the Barrow Navigation shall not be navigated at a speed in excess of 11km per hour except as necessary for safe navigation in conditions of fast flow.

Bank Erosion

Narrow sections of all the navigations are particularly prone to bank erosion due to the large wash generated by some craft. Masters are requested to be vigilant and to slow down to a speed sufficient to maintain steerage when they observe the wash of their craft inundating the river banks.

Unusual Waterborne Activity

Unusual waterborne vessels may be encountered from time to time, such as, hovercraft or amphibious aircraft / seaplanes. Masters of such craft are reminded to apply the normal “Rule of the Road” when they meet conventional craft on the water and to allow extra room to manoeuvre in the interest of safety.

Sailing Activity

Mariners will encounter large numbers of sailing dinghies from late June to August in the vicinity of Lough Derg, Lough Ree and Lower Lough Erne. Sailing courses are marked by yellow buoys to suit weather conditions on the day. Vessels should proceed at slow speed and with due caution and observe the rules of navigation when passing these fleets, as many of the participants are junior sailors under training.

Rowing

Mariners should expect to meet canoes and vessels under oars on any part of the navigations, but more so in the vicinity of Athlone, Carrick-on-Shannon, Coleraine, Enniskillen and Limerick. Masters are reminded to proceed at slow speed and especially to reduce their wash to a minimum when passing these craft as they can be easily upset and swamped due to their very low freeboard and always be prepared to give way in any given traffic situation.

Canoeing

Canoeing is an adventure sport and participants are strongly recommended to seek the advice of the sport’s governing bodies i.e Canoeing Ireland and the Canoe Association of Northern Ireland, before venturing onto the navigations.

Persons in charge of canoes are reminded of the inherent danger to these craft associated with operating close to weirs, sluice gates, locks and other infrastructure particularly when rivers are in flood and large volumes of water are moving through the navigations due to general flood conditions or very heavy localised precipitation e.g. turbulent and broken water, stopper waves. Shooting weirs is prohibited without prior permission of Waterways Ireland.

Canoeists should check with lockkeepers prior entering a lock to ensure passage is done in a safe manner. Portage is required at all unmanned locks.

Canoe Trail Network – "Blueways"

Masters of powered craft are reminded that a canoe trail network is being developed across all navigations and to expect more organised canoeing along these trails necessitating slow speed and minimum wash when encountering canoeists, rowing boats etc

Rockingham and Drummans Island Canals – Lough Key

It is expected that work on Rockingham and Drummans Island Canals on Lough Key will be completed in 2021. Access to these canals will be for non-powered craft only, eg canoes, kayaks, rowing boats.

Fast Powerboats and Personal Watercraft (Jet Skis)

Masters of Fast Powerboats (speed greater than 17kts) and Personal Watercraft (i.e.Jet Skis) are reminded of the inherent dangers associated with high speed on the water and especially in the confines of small bays and narrow sections of the navigations. Keeping a proper look-out, making early alterations to course and /or reducing speed will avoid conflict with slower vessels using the navigation. Personal Watercraft are not permitted to be used on the canals.

Towing Waterskiers, Wakeboarders, Doughnuts etc

Masters of vessels engaged in any of these activities are reminded of the manoeuvring constraints imposed upon their vessel by the tow and of the added responsibilities that they have to the person(s) being towed. These activities should be conducted in areas which are clear of conflicting traffic. It is highly recommended that a person additional to the master be carried to act as a “look-out” to keep the tow under observation at all times.

Prohibition on Swimming

Swimming in the navigable channel, particularly at bridges, is dangerous and is prohibited due to the risk of being run over by a vessel underway in the navigation.

Age Restrictions on operating of powered craft

In the Republic of Ireland, Statutory Instrument 921 of 2005 provides the legal requirements regarding the minimum age for operating of powered craft. The Statutory Instrument contains the following requirements:

- The master or owner of a personal watercraft or a fast power craft shall take all reasonable steps to ensure that a person who has not attained the age of 16 years does not operate or control the craft

- The master or owner of a pleasure craft powered by an engine with a rating of more than 5 horse power or 3.7 kilowatts shall take all reasonable steps to ensure that a person who has not attained the age of 12 years does not operate or control the craft.

Lifejackets and Personal Flotation Devices (PFDs)

Lifejackets and PFD’s are the single most important items of personal protective equipment to be used on a vessel and should be worn especially when the vessel is being manoeuvred such as entering / departing a lock, anchoring, coming alongside or departing a jetty or quayside.

In the Republic of Ireland, Statutory Instrument 921 of 2005 provides the legal requirements regarding the wearing of Personal Flotation Devices. The Statutory Instrument contains the following requirements:

- The master or owner of a pleasure craft (other than a personal watercraft) shall ensure, that there are, at all times on board the craft, sufficient suitable personal flotation devices for each person on board.

- A person on a pleasure craft (other than a personal watercraft) of less than 7 metres length overall shall wear a suitable personal flotation device while on board an open craft or while on the deck of decked craft, other than when the craft is made fast to the shore or at anchor.

- The master or owner of a pleasure craft (other than a personal watercraft) shall take all reasonable steps to ensure that a person who has not attained the age of 16 years complies with paragraph above.

- The master or owner of a pleasure craft (other than a personal watercraft), shall take all reasonable steps to ensure that a person who has not attained the age of 16 years wears a suitable personal flotation device while on board an open craft or while on the deck of a decked craft other than when it is made fast to the shore or at anchor.

- The master or owner of a pleasure craft (other than a personal watercraft) shall take all reasonable steps to ensure that a person wears a suitable personal flotation device, at all times while – (a) being towed by the craft, (b) on board a vessel or object of any kind which is being towed by the craft.

Firing Range Danger Area – Lough Ree

The attention of mariners is drawn to the Irish Defence Forces Firing Range situated in the vicinity of buoys No’s 2 and 3, on Lough Ree on the Shannon Navigation. This range is used regularly for live firing exercises, throughout the year, all boats and vessels should stay clear of the area marked with yellow buoys showing a yellow "X" topmark and displaying the word "Danger".

Shannon Navigation, Portumna Swing Bridge Tolls

No attempt should be made by Masters’ of vessels to pay the bridge toll while making way through the bridge opening. Payment will only be taken by the Collector from Masters when they are secured alongside the jetties north and south of the bridge.

Navigating from Killaloe to Limerick on the Shannon Navigation

The navigation from Killaloe to Limerick involves passage through Ardnacrusha locks, the associated headrace and tailrace and the Abbey River into Limerick City. Careful passage planning is required to undertake this voyage. Considerations include: lock passage at Ardnacrusha, water flow in the navigation, airdraft under bridges on Abbey River in Limerick, state of tide in Limerick

Users are advised to contact the ESB Ardnacrusha hydroelectric power station (00353 (0)87 9970131) 48 hours in advance of commencing their journey to book passage through the locks at Ardnacrusha. It is NOT advised to undertake a voyage if more than one turbine is operating (20MW), due to the increased velocity of flow in the navigation channel, which can be dangerous. To ascertain automatically in real time how many turbines are running, users can phone +353 (0)87 6477229.

For safety reasons the ESB has advised that only powered craft with a capacity in excess of 5 knots are allowed to enter Ardnacrusha Headrace and Tailrace Canals.

Passage through Sarsfield Lock should be booked on +353-87-7972998, on the day prior to travel and it should be noted also that transit is not possible two hours either side of low water.

A Hydrographic survey in 2020 of the navigation channel revealed that the approach from Shannon Bridge to Sarsfield Lock and the Dock area has silted up. Masters of vessels and water users are advised to navigate to the Lock from Shannon bridge on a rising tide one or two hours before High Tide.

Lower Bann Navigation

The attention of all users is drawn to the “Users Code for the Lower Bann”, in particular to that section covering “Flow in the River” outlining the dangers for users both on the banks and in the navigation, associated with high flow rates when the river is in spate. Canoeists should consult and carry a copy of the “Lower Bann Canoe Trail” guide issued by the Canoe Association of Northern Ireland. Users should also contact the DfI Rivers Coleraine, who is responsible for regulating the flow rates on the river, for advisory information on the flow rates to be expected on any given day.

DfI Rivers Coleraine. Tel: 0044 28 7034 2357 Email: [email protected]

Lower Bann Navigation – Newferry – No wake zone

A No Wake Zone exists on the Lower Bann Navigation at Newferry. Masters of vessels are requested to proceed at a slow speed and create no wake while passing the jetties and slipways at Newferry.

Overhead Power Lines (OHPL) and Air draft

All Masters must be aware of the dangers associated with overhead power lines, in particular sailing vessels and workboats with cranes or large air drafts. Voyage planning is a necessity in order to identify the location of overhead lines crossing the navigation.

Overhead power line heights on the River Shannon are maintained at 12.6metres (40 feet) from Normal Summer level for that section of navigation, masters of vessels with a large air draft should proceed with caution and make additional allowances when water levels are high.

If a vessel or its equipment comes into contact with an OHPL the operator should NOT attempt to move the vessel or equipment. The conductor may still be alive or re-energise automatically. Maintain a safe distance and prevent third parties from approaching due to risk of arcing. Contact the emergency services for assistance.

Anglers are also reminded that a minimum ground distance of 30 metres should be maintained from overhead power lines when using a rod and line.

Submarine Cables and Pipes

Masters of vessels are reminded not to anchor their vessels in the vicinity of submarine cables or pipes in case they foul their anchor or damage the cables or pipes. Look to the river banks for signage indicating their presence.

Water Levels - Precautions

Low Water Levels:

When water levels fall below normal summer levels masters should be aware of:

Navigation

To reduce the risk of grounding masters should navigate on or near the centreline of the channel, avoid short cutting in dog-legged channels and navigating too close to navigation markers.

Proceeding at a slow speed will also reduce “squat” effect i.e. where the vessel tends to sit lower in the water as a consequence of higher speed.

Slipways

Reduced slipway length available under the water surface and the possibility of launching trailers dropping off the end of the concrete apron.

More slipway surface susceptible to weed growth requiring care while engaged in launching boats, from slipping and sliding on the slope. Note also that launching vehicles may not be able to get sufficient traction on the slipway once the craft is launched to get up the incline.

Bank Erosion

Very dry riverbanks are more susceptible to erosion from vessel wash.

Lock Share

Maximising on the number of vessels in a lock will ensure that the total volume of water moving downstream is decreased. Lock cycles should be used for vessels travelling each way.

High Water Levels:

When water levels rise above normal summer level masters should be aware of:

Navigation

Navigation marks will have reduced height above the water level or may disappear underwater altogether making the navigable channel difficult to discern.

In narrow sections of the navigations water levels will tend to rise more quickly than in main streams and air draft at bridges will likewise be reduced.

There will also be increased flow rates particularly in the vicinity of navigation infrastructure such as bridges, weirs, locks etc where extra care in manoeuvring vessels will be required.

Harbours and Jetties

Due care is required in harbours and at slipways when levels are at or near the same level as the harbour walkways' as the edge will be difficult to discern especially in reduced light conditions. It is advised that Personal Flotation Devices be worn if tending to craft in a harbour in these conditions.

Slipways

Slipways should only be used for the purpose of launching and recovering of water craft or other objects from the water. Before using a slipway it should be examined to ensure that the surface has sufficient traction/grip for the intended purpose such as launching a craft from a trailer using a vehicle, that there is sufficient depth of water on the slipway to float the craft off the trailer before the concrete apron ends and that the wheels of the trailer do not drop off the edge of the slipway. That life-saving appliances are available in the vicinity, that the vehicle is roadworthy and capable of coping with the weight of the trailer and boat on the incline. It is recommended that slipway operations are conducted by two persons.

Caution to be Used in Reliance upon Aids to Navigation

The aids to navigation depicted on the navigation guides comprise a system of fixed and floating aids to navigation. Prudent mariners will not rely solely on any single aid to navigation, particularly a floating aid to navigation. With respect to buoys, the buoy symbol is used to indicate the approximate position of the buoy body and the ground tackle which secures it to the lake or river bed. The approximate position is used because of the practical limitations in positioning and maintaining buoys in precise geographical locations. These limitations include, but are not limited to, prevailing atmospheric and lake/river conditions, the slope of and the material making up the lake/river bed, the fact that the buoys are moored to varying lengths of chain, and the fact that the buoy body and/or ground tackle positions are not under continuous surveillance. Due to the forces of nature, the position of the buoy body can be expected to shift inside and outside the charted symbol.

Buoys and perches are also moved out of position or pulled over by those mariners who use them to moor up to instead of anchoring. To this end, mariners should always monitor their passage by relating buoy/perch positions with the published navigation guide. Furthermore, a vessel attempting to pass close by always risks collision with a yawing buoy or with the obstruction that the buoy or beacon/perch marks.

Masters of Vessels are requested to use the most up to date Navigation guides when navigating on the Inland Waterways.
