The Loughs Agency says it welcomes the new legislation to protect basking sharks in Irish waters.

As reported by Afloat.ie on Monday (3 October), measures to accord the status of ‘protected wild animal’ on basking sharks under the Wildlife Act were signed into law by Minister for Marine Charlie McConalogue and Minister of State for Heritage Malcolm Noonan.

The Irish Basking Shark Group (IBSG) was among the organisations responsible for pushing the new regulations through. The group’s ‘Save our Shark’ campaign garnered the support of over 12,000 members of the public signing an online petition.

The basking shark has been classified as endangered on the International Union for Conservation of Nature’s red list of globally threatened species, with its status changing from vulnerable to endangered globally in 2019.

It is now protected from hunting, injury and wilful destruction of its breeding and resting places in Irish waters under the Wildlife Act. However, the Social Democrats are calling for a protection plan “with the necessary resources” for the second-largest fish in the oceans.

Basking sharks have been frequently sighted in both Loughs Agency catchments— in Lough Foyle off the coast of Donegal as well as in Carlingford Lough.

The Loughs Agency is the cross-border body for the fisheries and marine resources of the Foyle and Carlingford areas and says it has been heavily involved in conservation efforts for the basking shark and other marine wildlife species as part of the SeaMonitor Project, with further updates available in the near future.

Sharon McMahon, chief executive of the Loughs Agency said: “We welcome the news that these stunning creatures are now designated as protected under Ireland’s Wildlife Act.

“The threat of extinction is on the increase for the basking shark, and as our waters constitute one of the most internationally important coastal regions for the species, this announcement will serve to ensure our loughs remain a safe space.

“On behalf of Loughs Agency, I would like to thank Ministers Noonan and McConalogue for signing off these regulations.”

The move has also been welcomed as “a huge step forward” by campaign network Fair Seas, though its policy officer Dr Donal Griffin added: “We can do even more to make sure basking sharks thrive in Irish waters.”

Fair Seas says new regulations giving legal protection to basking sharks mark a huge step forward in conserving the globally threatened species.

As of October 3rd 2022, basking sharks in Irish waters are legally protected under Section 23 of Ireland’s Wildlife Act.

The coalition of Ireland’s leading environmental non-governmental organisations and networks believes that an ‘ecosystem-based approach’ to conservation is required to give species like the basking shark a genuine chance of recovery.

The Fair Seas report ‘Revitalising Our Seas’ is encouraging the government to implement this approach to their ambition of protecting 30% of Irish waters with a network of Marine Protected Areas by 2030.

Aoife O’Mahony, Fair Seas campaign manager, said, ‘It is such a special moment to see a basking shark up close, it is something people remember for the rest of their lives. However, we must also remember these enormous fish are ‘wildlife’ and need to be treated with respect. The legal protection for these animals announced today is such good news and fundamental to their long-term conservation in Ireland. This is another step in the right direction to conserve and protect our marine habitats and species, the next step of finalising Marine Protected Areas legislation this year will help build on successes like today's announcement.”

Dr Donal Griffin, Fair Seas marine policy officer and Irish Basking Shark Group (IBSG) co-coordinator, said, “Given that basking sharks are classified as ‘endangered’, this is a huge step forward in ensuring Ireland remains a place worth visiting for these animals in the future. Yet we can do even more to make sure basking sharks thrive in Irish waters. Ireland has committed to protecting 30% of its seas by 2030, and along with many other nationally and globally important marine species, the basking shark must be a key consideration in Ireland’s future Marine Protected Area network.”

Basking sharks are the second biggest fish in the sea, with females only reaching sexual maturity once they have grown to between 8 and 10 metres in length.

These fish are most often spotted off Donegal, Mayo, Cork and Kerry coasts. Several records show between 60 and 75 individuals in a single sighting.

More than 100 basking sharks were spotted in the waters off Hook Head in Co Wexford last week as their season for 2022 starts “with a bang”, as the Irish Whale and Dolphin Group reports.

A member of the public, Charlie O’Malley observed the massive congregation of the ocean’s second largest fish last Thursday (24 March) just six-to-eight miles southwest of Hook Head.

Not only were they great in number, but in size too — with O’Malley estimating many larger specimens of the marine wildlife giant of over 20ft in length.

“We have no reason to doubt the veracity of this report,” said IWDG sightings officer Pádraig Whooley. “Charlie hails from Achill Island and basking sharks are a species that run in his blood.”

Whooley said this “incredible kick-start” to the 2022 basking shark season follows a “good year” for sightings in 2021, with 161 validated by the IWDG — though the peak was between 2009 and 2011 when an average of more than 200 per annum were validated.

Sightings have also come in from Inis Mór in the Aran Islands and Baltimore in West Cork, and more are expected in the coming weeks — not least because these sharks have been in the news recently owing to their newly gained legal protection under the Wildlife Act, as reported on Afloat.ie.

Basking sharks are to be given protection by the Government under the Wildlife Act, Minister for Heritage Malcolm Noonan has announced.

The move follows a long campaign by marine scientists, NGOs and school students for protection of Cetorhinus maximus the world’s second-largest shark and fish – known as Liabhán chor gréine, or the “great fish of the sun”.

The number of breeding individuals has been estimated at approximately 8,000-10,000 worldwide, the majority of which are in the north-east Atlantic.

Noonan said that it would be afforded “protected wild animal” status under the Wildlife Act, and this will be supported by development of a code of conduct for sustainable wildlife tourism.

In an open letter last year appealing to the Government for protection of the basking shark, a group of scientists explained that Irish coastal waters are “one of the few places globally” where basking sharks “regularly and predictably occur on the surface close to shore”.

“This surface swimming behaviour is the root of its deep cultural connections with western Irish coastal and island communities,” the scientists said.

“ Current threats to the survival of these magnificent animals include harassment and disturbance, ship collisions, and entanglement,” they stated.

Basking sharks were hunted by the Irish whaling industry in the early 18th century, including off Achill, Co Mayo where thousands of sharks were caught and processed for their liver oil until the 1970s.

“ It may be a surprise for some to hear that it was legal to fish for the basking shark in Irish waters until 2001 and not prohibited in all EU waters until 2006,” the scientists said.

“ Due to these unsustainable practices the shark is now classified by the International Union for the Conservation of Nature (IUCN) as endangered in the northeast Atlantic,” they stated.

Noonan said that work had been underway in his department for a number of months to progress protections for the basking shark.

“ I’m delighted to be able to announce today that they will be finalised in the near future,” Noonan said.

“ Basking sharks are extraordinary creatures and they’re facing increasing pressures from a range of sources, including disturbance,” he said.

“ This move will confer legal protections on them in the short term and enhance their protection in the longer term through the collaborative development of a Code of Conduct to support best practice in sustainable eco tourism,” he said.

He paid tribute to colleagues Minister for Marine Charlie McConalogue and Minister for Foreign Affairs and Defence Simon Coveney “for their support in progressing this important work.

Noonan also thanked “the many members of the public – particularly the young children – who have been so passionate in calling for basking shark protection”.

Minister for Housing, Local Government and Heritage Darragh O’Brien said that “marine protection is a vital element of the work we do in this department”.

He said that “strong progress is being made in that regard, particularly on Marine Protected Areas (MPAs), which will form a crucial pillar in ensuring that we have a clean, healthy, diverse and sustainably used marine environment.”

Under Section 23(2)(a) of the Wildlife Act 1976, it is an offence to:

hunt a protected wild animal (unless under permission or licence granted by my Department)

injure a protected wild animal (unless done while hunting in accordance with a licence or exemption cited above), or

wilfully interfere with or destroy the breeding or resting places of a protected wild animal.

The two ministers said the National Parks and Wildlife Service will be engaging with the marine eco-tourism, recreation at sea and wildlife watching industries, as well as environmental NGOs, to develop a code of conduct.

This aims to ensure that “there is strong awareness of and accordance with best practice for operators and the public in observing or encountering marine wildlife such as basking sharks, as well as other species of fish, marine mammals and birds”, they said.

Noonan also indicated his intention to “progress the Programme for Government commitment to review the Wildlife Act”.

This will involve a detailed examination of protections and provisions in the Act, enabling a broader consideration of its effectiveness, he said.

Ten to twenty per cent of the world's basking sharks are in Irish waters year-round. Because of this an international consortium of leading scientists and conservation organisations has today called on the Irish Government to provide legal protection for them.

"Ireland needs to do this," according to Dr Emmett Johnston, Founder Member of the Irish Basking Shark Group which has made the call on World Oceans Day. "The scientific community have given their full support to list the basking shark under the Wildlife Act. Now is the right time to protect them and their habitats. Irish coastal waters are one of the few places globally that basking sharks regularly and predictably occur on the surface close to shore.

As Afloat reported earlier, the number of breeding individuals has been estimated at approximately 8,000-10,000 worldwide, most of which are in the northeast Atlantic.

On Tom MacSweeney's Maritime Ireland Radio Show another Founder/Member of the Group, Dr Simon Berrow, who is also CEO of the Irish Whale and Dolphin Group, said that during the Summer months basking sharks also suffer harassment and disturbance from boats, jet skis, divers and snorkelers.

More than 2,000 people have already signed an online petition in support of legal protection for basking sharks in Irish waters.

The appeal was started by Simon Berrow of the Irish Whale and Dolphin Group to encourage TDs to support The Wildlife (Amendment) Bill 2021 tabled last week by Social Democrats TD Jennifer Whitmore.

As previously reported on Afloat.ie, the bill would make it illegal for anyone to intentionally or recklessly injure, disturb or harass the second-largest fish in the world’s oceans.

While basking sharks are an endangered species, they are currently not afforded the same protections in law as whales, dolphins, porpoise and seals in Irish waters.

Berrow says: "Ireland and our coastal communities have historically benefited from basking shark fisheries and today we have a duty to provide protection for this highly mobile species when they occupy Irish territorial waters."

He adds: "Adding the species to Schedule Five of the Wildlife Act (1976) as amended is the simplest method to provide protection for the species in Irish territorial waters."

A Wicklow TD with a background in fisheries science and environmental law has introduced a bill that would afford stronger protections to basking sharks in Irish waters, as TheJournal.ie reports.

The Wildlife (Amendment) Bill 2021 tabled by Dáil deputy Jennifer Whitmore of the Social Democrats would make it illegal for anyone to intentionally or recklessly injure, disturb or harass the second-largest fish in the world’s oceans.

Experts estimate that as much as one-fifth of the global population of basking sharks may be found in Irish waters, though remarkably little is known about their lives — something researchers from Trinity have set out to discover by tagging a number of them off West Cork.

“We have a deep cultural connection to this animal and it is often a symbol of our indigenous maritime life,” Whitmore told the Dáil on Thursday (13 May).

However, the endangered marine wildlife giants are not a protected species in Ireland like cetaceans (dolphins, porpoise and whales) and seals.

TheJournal.ie has more on the story HERE.

Researchers from Trinity’s School of Natural Sciences were in West Cork earlier this month to tag some of the many basking sharks that have been frequenting our shores — and learn more about the second largest fish in the world’s oceans.

Funded by the Irish Research Council and Science Foundation Ireland, Assistant Professor Nicholas Payne and PhD candidate Haley Dolton spent a week on the water with West Cork Charters in which they managed to apply tags to four basking sharks.

These electronic tags will accumulate data about the sharks’ behaviour and physiology as they move around the coast feeding on plankton.

The goal, the researchers say, is to learn more about the anatomy and physiology of these gentle giants and hopefully guide conservation efforts for this endangered marine wildlife species.

“Basking sharks are a difficult species to study because they are not very abundant and they only grace our shores for a brief period each year, from April to August, so I am delighted we were able to learn so much about them this past week,” said Dr Payne.

Sadly the first phase of the pair’s work involved dissecting the remains of two basking sharks that washed up on the West Cork coast at the end of April, as previously reported on Afloat.ie.

“We would rather not have have had the opportunity to examine the two sharks that died prematurely before we took to the sea, but these sad events did at least help us learn more about them,” Dr Payne explained.

“Basking sharks are an endangered species and at risk of death from fishing bycatch and from getting struck by boats, so the more we know about them — especially their behaviour and physiology — the better chance we have of protecting them.

“The experience we had of observing live sharks in all their glory really emphasises that we should do our best to protect these incredible animals.”

Dolton added: “The amount of data we managed to collect throughout the whole week was phenomenal and beyond what I’d hoped for. We are currently analysing all the results and look forward to sharing our findings with everyone later in the year.”

The carcass of a second basking shark has washed up on the coast of West Cork just days after the discovery of an unusually fresh specimen 20km away.

According to Cork Beo, the second large fish was found at the weekend near Courtmacsherry and is believed to have been dead for some time.

Another basking shark carcass measuring a whopping seven metres that beached at Inchydoney last week presented a rare opportunity for marine biologists to examine relatively fresh remains.

It’s unknown how the female shark died, but dissection revealed that the marine wildlife giant still had food in its stomach.

“It’s sad of course to see such a big beautiful animal like that, but it’s good to try and get something positive out of it,” Trinity lecturer Dr Nicholas Payne said.

Basking sharks have been spotted in great numbers off West Cork this month, with video of a kayaker surrounded by the second biggest fish in the sea making a splash last week.

Next Tuesday 13 April the Cork Nature Network hosts a free talk in the impact of microplastics on the marine environment, and specifically on the largest fish in the sea.

During this talk, Dr Alina Wieczorek will be presenting her research — being conducted both in Ireland and the Maldives in the Indian Ocean — on microplastic interactions with whale sharks and basking sharks.

She will also share some first insights into how researchers can use scientific findings to inform society and stakeholders to collaboratively find solutions to address environmental issues such as plastic pollution.

Online attendance for ‘Microplastics a Macro-Disaster: A threat to the largest fish of our seas?’ at 7pm next Tuesday 13 April is free, and registration is open now at Eventbrite.

Ireland's Offshore Renewable Energy

Because of Ireland's location at the Atlantic edge of the EU, it has more offshore energy potential than most other countries in Europe. The conditions are suitable for the development of the full range of current offshore renewable energy technologies.

Offshore Renewable Energy FAQs

Offshore renewable energy draws on the natural energy provided by wind, wave and tide to convert it into electricity for industry and domestic consumption.

Offshore wind is the most advanced technology, using fixed wind turbines in coastal areas, while floating wind is a developing technology more suited to deeper water. In 2018, offshore wind provided a tiny fraction of global electricity supply, but it is set to expand strongly in the coming decades into a USD 1 trillion business, according to the International Energy Agency (IEA). It says that turbines are growing in size and in power capacity, which in turn is "delivering major performance and cost improvements for offshore wind farms".

The global offshore wind market grew nearly 30% per year between 2010 and 2018, according to the IEA, due to rapid technology improvements, It calculated that about 150 new offshore wind projects are in active development around the world. Europe in particular has fostered the technology's development, led by Britain, Germany and Denmark, but China added more capacity than any other country in 2018.

A report for the Irish Wind Energy Assocation (IWEA) by the Carbon Trust – a British government-backed limited company established to accelerate Britain's move to a low carbon economy - says there are currently 14 fixed-bottom wind energy projects, four floating wind projects and one project that has yet to choose a technology at some stage of development in Irish waters. Some of these projects are aiming to build before 2030 to contribute to the 5GW target set by the Irish government, and others are expected to build after 2030. These projects have to secure planning permission, obtain a grid connection and also be successful in a competitive auction in the Renewable Electricity Support Scheme (RESS).

The electricity generated by each turbine is collected by an offshore electricity substation located within the wind farm. Seabed cables connect the offshore substation to an onshore substation on the coast. These cables transport the electricity to land from where it will be used to power homes, farms and businesses around Ireland. The offshore developer works with EirGrid, which operates the national grid, to identify how best to do this and where exactly on the grid the project should connect.

The new Marine Planning and Development Management Bill will create a new streamlined system for planning permission for activity or infrastructure in Irish waters or on the seabed, including offshore wind farms. It is due to be published before the end of 2020 and enacted in 2021.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE. Is there scope for community involvement in offshore wind? The IWEA says that from the early stages of a project, the wind farm developer "should be engaging with the local community to inform them about the project, answer their questions and listen to their concerns". It says this provides the community with "the opportunity to work with the developer to help shape the final layout and design of the project". Listening to fishing industry concerns, and how fishermen may be affected by survey works, construction and eventual operation of a project is "of particular concern to developers", the IWEA says. It says there will also be a community benefit fund put in place for each project. It says the final details of this will be addressed in the design of the RESS (see below) for offshore wind but it has the potential to be "tens of millions of euro over the 15 years of the RESS contract". The Government is also considering the possibility that communities will be enabled to invest in offshore wind farms though there is "no clarity yet on how this would work", the IWEA says.

Based on current plans, it would amount to around 12 GW of offshore wind energy. However, the IWEA points out that is unlikely that all of the projects planned will be completed. The industry says there is even more significant potential for floating offshore wind off Ireland's west coast and the Programme for Government contains a commitment to develop a long-term plan for at least 30 GW of floating offshore wind in our deeper waters.

There are many different models of turbines. The larger a turbine, the more efficient it is in producing electricity at a good price. In choosing a turbine model the developer will be conscious of this ,but also has to be aware the impact of the turbine on the environment, marine life, biodiversity and visual impact. As a broad rule an offshore wind turbine will have a tip-height of between 165m and 215m tall. However, turbine technology is evolving at a rapid rate with larger more efficient turbines anticipated on the market in the coming years.

 

The Renewable Electricity Support Scheme is designed to support the development of renewable energy projects in Ireland. Under the scheme wind farms and solar farms compete against each other in an auction with the projects which offer power at the lowest price awarded contracts. These contracts provide them with a guaranteed price for their power for 15 years. If they obtain a better price for their electricity on the wholesale market they must return the difference to the consumer.

Yes. The first auction for offshore renewable energy projects is expected to take place in late 2021.

Cost is one difference, and technology is another. Floating wind farm technology is relatively new, but allows use of deeper water. Ireland's 50-metre contour line is the limit for traditional bottom-fixed wind farms, and it is also very close to population centres, which makes visibility of large turbines an issue - hence the attraction of floating structures Do offshore wind farms pose a navigational hazard to shipping? Inshore fishermen do have valid concerns. One of the first steps in identifying a site as a potential location for an offshore wind farm is to identify and assess the level of existing marine activity in the area and this particularly includes shipping. The National Marine Planning Framework aims to create, for the first time, a plan to balance the various kinds of offshore activity with the protection of the Irish marine environment. This is expected to be published before the end of 2020, and will set out clearly where is suitable for offshore renewable energy development and where it is not - due, for example, to shipping movements and safe navigation.

YEnvironmental organisations are concerned about the impact of turbines on bird populations, particularly migrating birds. A Danish scientific study published in 2019 found evidence that larger birds were tending to avoid turbine blades, but said it didn't have sufficient evidence for smaller birds – and cautioned that the cumulative effect of farms could still have an impact on bird movements. A full environmental impact assessment has to be carried out before a developer can apply for planning permission to develop an offshore wind farm. This would include desk-based studies as well as extensive surveys of the population and movements of birds and marine mammals, as well as fish and seabed habitats. If a potential environmental impact is identified the developer must, as part of the planning application, show how the project will be designed in such a way as to avoid the impact or to mitigate against it.

A typical 500 MW offshore wind farm would require an operations and maintenance base which would be on the nearby coast. Such a project would generally create between 80-100 fulltime jobs, according to the IWEA. There would also be a substantial increase to in-direct employment and associated socio-economic benefit to the surrounding area where the operation and maintenance hub is located.

The recent Carbon Trust report for the IWEA, entitled Harnessing our potential, identified significant skills shortages for offshore wind in Ireland across the areas of engineering financial services and logistics. The IWEA says that as Ireland is a relatively new entrant to the offshore wind market, there are "opportunities to develop and implement strategies to address the skills shortages for delivering offshore wind and for Ireland to be a net exporter of human capital and skills to the highly competitive global offshore wind supply chain". Offshore wind requires a diverse workforce with jobs in both transferable (for example from the oil and gas sector) and specialist disciplines across apprenticeships and higher education. IWEA have a training network called the Green Tech Skillnet that facilitates training and networking opportunities in the renewable energy sector.

It is expected that developing the 3.5 GW of offshore wind energy identified in the Government's Climate Action Plan would create around 2,500 jobs in construction and development and around 700 permanent operations and maintenance jobs. The Programme for Government published in 2020 has an enhanced target of 5 GW of offshore wind which would create even more employment. The industry says that in the initial stages, the development of offshore wind energy would create employment in conducting environmental surveys, community engagement and development applications for planning. As a site moves to construction, people with backgrounds in various types of engineering, marine construction and marine transport would be recruited. Once the site is up and running , a project requires a team of turbine technicians, engineers and administrators to ensure the wind farm is fully and properly maintained, as well as crew for the crew transfer vessels transporting workers from shore to the turbines.

The IEA says that today's offshore wind market "doesn't even come close to tapping the full potential – with high-quality resources available in most major markets". It estimates that offshore wind has the potential to generate more than 420 000 Terawatt hours per year (TWh/yr) worldwide – as in more than 18 times the current global electricity demand. One Terawatt is 114 megawatts, and to put it in context, Scotland it has a population a little over 5 million and requires 25 TWh/yr of electrical energy.

Not as advanced as wind, with anchoring a big challenge – given that the most effective wave energy has to be in the most energetic locations, such as the Irish west coast. Britain, Ireland and Portugal are regarded as most advanced in developing wave energy technology. The prize is significant, the industry says, as there are forecasts that varying between 4000TWh/yr to 29500TWh/yr. Europe consumes around 3000TWh/year.

The industry has two main umbrella organisations – the Irish Wind Energy Association, which represents both onshore and offshore wind, and the Marine Renewables Industry Association, which focuses on all types of renewable in the marine environment.
