Bord Iascaigh Mhara (BIM), Ireland’s Seafood Development Agency, in association with IFA Aquaculture, is hosting a two-day seminar today (Thursday 13th February 2020) for members of Ireland’s vibrant oyster farming sector, valued at €43million according to the latest (2018) Business of Seafood report. The sold-out event, taking place in Carlingford, Co Louth, has attracted participants from more than 85% of businesses in the industry.

Speaking at the opening of the workshop, BIM’s chief executive, Jim O’Toole said, “The demand for Irish oysters continues to increase in Ireland and overseas. Consumers in Europe and Asia are actively seeking out Irish oysters and cite the unique characteristics and diversity in taste between brands. This strong and growing reputation has translated into strong prices for Irish oysters and excellence in food safety management and stringent attention to quality control among industry members accounts for much of these successes. BIM continues to support and work closely with the sector. It is a sector that has enormous potential to continue in its upwards growth trajectory and to further benefit those living and working in coastal communities throughout Ireland.”

The sector enjoyed a positive year in 2018, according to the BIM Business of Seafood report, producing an all-time high of 10,300 tonnes of oysters and employing 1,300 people nationwide. The seminar is taking place in an area renowned for its quality oyster production and will feature presentations from a host of experts on practical topics of immediate interest to the Irish sector.

Despite recent health and socio-economic challenges presented by the Asian market that have affected exports Irish oyster producers remain at the forefront of the luxury offering, with the sector showing continued investment in packaging and branding, focusing on Irish oyster’s superior quality. The latest figures show nearly 30% of Irish oysters are now packed and branded in Ireland prior to export, adding extra value to the sector. While France remains our largest export market at 74% of total export volume in 2018, we are continuing to diversify into alternative European markets such as the Netherlands and Belgium (2019 saw a 31% increase in exports to the Netherlands).

The morning session will include short ‘flash’ presentations from IFA Aquaculture on where we are as an industry, the latest BIM initiatives which aim to further promote sustainability, innovation and competitiveness in the Oyster Sector as well as some of the more innovative approaches from industry to further develop their businesses.

The second part of the morning session will look at some of the results from BIM’s Bluefish Climate Change project, funded by the Ireland Wales Programme. There will be an overview of our current trade position and opportunities for further expansion. We will also be joined by Bord Bia to highlight oyster promotional events in Europe throughout 2020 and the Food Safety Authority of Ireland to take us through some of the possible implications of Brexit in terms of food safety regulations.

Speakers from the Marine Institute, the SFPA and other industry experts will focus the afternoon session on topics such as water quality biosecurity, biotoxins and other environmental factors which significantly affect both oyster production and trade

The final aspect of the workshop will be an informed panel discussion, based on the day's presentations and addressing questions posed by workshop attendees.

The latest research and knowledge on oyster diseases was presented at a meeting on Pacific oyster health held recently by the Marine Institute’s Fish Health Unit.

The event attracted more than 80 participants from Ireland’s oyster farming industry, as well as representatives from Ireland’s seafood development agency Bord Iascaigh Mhara.

Presentations focused on mortality, disease management and current national and international research in oyster health.

Oyster mortalities in recent years in Ireland have been mainly associated with either Ostreid herpes virus-1 μVar (OsHV-1 μVar) infection or the bacterium Vibrio aestuarianus. Both diseases cause significant oyster mortality events and an economic loss to oyster farmers and producers.

Researchers from the Marine Institute and University College Cork presented the major findings from the REPOSUS project, funded by the Department of Agriculture, Food and the Marine’s FIRM programme.

The three-year REPOSUS project focused on reducing the impact of pathogens associated with mortalities in Pacific oysters. This included results from sentinel trials in disease impacted bays, molecular and pathogenicity characterisation studies on isolates of OsHV-1 and rache and studies on environmental parameters which influence mortality.

French institute IFREMER also presented the latest results from the VIVALDI project (Preventing and Migrating Farmed Bivalve Diseases) funded by the EU’s Horizon 2020 research and innovation programme.

VIVALDI combines European research resources to better understand shellfish diseases and improve the sustainability and competitiveness of the European shellfish industry. The Marine Institute is one of 21 partners involved in this research project.

Industry representatives from Ireland also shared their experience of managing losses in shellfish production due to oyster disease and mortality on their sites.

This feedback, along with research presented, will be used to update the current best practice guide for disease control and management in Ireland's oyster industry.

#Oysters - Unauthorised oysters farms have exploded in number on Lough Foyle amid a continued dispute over its ownership, as the Belfast Telegraph reports.

The estuary between the counties of Donegal and Derry remains a point of contention as Brexit looms, with both the UK and Irish governments claiming dominion over its waters.

As a result, there has been a proliferation of unregulated oyster farming that could be worth £20 million or €22.89 million each year, according to the Loughs Agency.

On Tuesday 5th June 2018, a man was convicted by Judge Mary Fahy at Galway District Court for being in possession of 1,425 undersized native oysters (Ostrea edulis), contrary to Bye-Law 628 of 1982.

Patrick Cormican, with an address at Newline, Maree, County Galway, pleaded guilty to a single charge of being in possession of the undersize native oysters when apprehended by Fisheries Officers at approximately 1pm on 7th December 2017, at Blackweir, County Galway.

Solicitor Dioraí Ford, representing Inland Fisheries Ireland, outlined to the court that Fisheries Officers observed Mr. Cormican loading bags of oysters into a tractor-trailer at Blackweir on that date. The officers were aware that these bags contained undersized oysters. Mr. Cormican is a licenced oyster fisherman and on the day in question had approximately 5,000 oysters, of which 1,425 were undersized. Officers spent over an hour and a half measuring and counting the oysters.

The court heard that Mr. Cormican was co-operative on the day in question and had a previous conviction in relation to oysters dating from 1991. Judge Fahy commented on how serious a matter this was, particularly with the local connection with the world famous Clarinbrige Oyster. Mr Ford outlined that the Fisheries Officers involved in the case had never seen such an amount of undersized oysters before while carrying out an inspection of this type.

Judge Fahy convicted Mr. Cormican and imposed a fine of €750. Costs of €800 were also awarded against Mr. Cormican.

Oysters in Ireland

There are two species of oysters commonly eaten in Ireland – the native oyster (Ostrea edulis) and the non-native Pacific oyster (Crassostrea gigas). The native oyster grows wild and is typically caught by licensed dredging, while the Pacific oyster is most commonly farmed on trestles and harvested mechanically.

Native oyster stocks are under threat and sustainable fishing requires adherence to size limits, in order to allow oysters to grow large enough to breed before harvesting. The minimum legal size is 76mm. Inland Fisheries Ireland is charged with protection of oysters, and conducts regular inshore patrols to check for compliance. Sales outlets such as fishmongers and restaurants should be familiar with the legal requirements and refuse to accept undersize oysters.

#Fishing - Fishermen wishing to apply for oyster dredge licences for the 2018 season must submit a completed official form to the relevant River Basin District Office before noon on Friday 24 November.

This process became necessary due to the fact that there are many Special Areas of Conservation (SACs) and Natura 2000 sites in Ireland that also contain oyster fisheries.

As the exploitation of these fisheries will require dredging, appropriate assessment of these fishing activities will have to be undertaken.

In the absence of appropriate assessments, against predetermined conservation objectives, it is necessary to ensure that no intensification of the fishing activity for oysters be permitted.

This has been further strengthened by the issuing of a direction from the minister in accordance with Section 278 (5)(a) of the Fisheries (Consolidation) Act 1959 as amended and the Habitats Directive as transposed by European Commission (Birds and Natural Habitats) Regulations 2011 (SI 477/ 2011).

As yet, no appropriate assessment of the potential impact of the wild oyster fishery has been completed for most locations within SACs and, in the absence of the necessary advice, Inland Fisheries Ireland must ensure that no intensification of the oyster fishery takes place.

As a consequence, IFI must continue to limit the number of licences that can be issued for 2017.

The official procedure and application form are available for download at the IFI website HERE.

Applicants must complete the application form in full and ensure that any relevant information that will assist IFI in assessing their application is submitted with the application.

The relevant licence fee for 2018 is €89 and this must also accompany the application. Unsuccessful applicants will have their fee refunded in full. Further information on the process is available with the application form.

Application forms are also available from Inland Fisheries Ireland, Teach Breac, Earl’s Island, Galway, H91 K6D2 (Tel 091 563118), from any Inland Fisheries Ireland District Office, or from Inland Fisheries Ireland head office, 3044 Lake Drive, Citywest Business Campus, Dublin 24, D24 Y265.

#Seafood - Donegal's oyster industry has been hit by an import ban in Hong Kong over an outbreak of food poisoning.

According to The Irish Times, food safety investigators in the Chinese territory were notified by Irish authorities two weeks ago that the presence of norovirus was confirmed at a raw oyster processing plant in the north-eastern county that services the crucial Asian market.

Hong Kong subsequently banned the import of raw oysters from Donegal "for the sake of prudence". More HERE.

Sharks in Irish waters

Irish waters are home to 71 species of shark, skates and rays, 58 of which have been studied in detail and listed on the Ireland Red List of Cartilaginous fish. Irish sharks range from small Sleeper sharks, Dogfish and Catsharks, to larger species like Frilled, Mackerel and Cow sharks, all the way to the second largest shark in the world, the Basking shark. 

Irish waters provide a refuge for an array of shark species. Tralee Bay, Co. Kerry provides a habitat for several rare and endangered sharks and their relatives, including the migratory tope shark, angel shark and undulate ray. This area is also the last European refuge for the extremely rare white skate. Through a European Maritime and Fisheries Fund (EMFF) project, Marine Institute scientists have been working with fishermen to assess the distribution, diversity, and monthly relative abundance of skates and rays in Tralee, Brandon and Dingle Bays.

“These areas off the southwest coast of Ireland are important internationally as they hold some of the last remaining refuges for angel shark and white skate,” said Dr Maurice Clarke of the Marine Institute. “This EMFF project has provided data confirming the critically endangered status of some species and provides up-to-date information for the development of fishery measures to eliminate by-catch.” 

Irish waters are also home to the Black Mouthed Catshark, Galeus melastomus, one of Ireland’s smallest shark species which can be found in the deep sea along the continental shelf. In 2018, Irish scientists discovered a very rare shark-nursery 200 nautical miles off the west coast by the Marine Institute’s ROV Holland 1 on a shelf sloping to 750 metres deep. 

There are two ways that sharks are born, either as live young or from egg casings. In the ‘case’ of Black Mouthed Catsharks, the nursery discovered in 2018, was notable by the abundance of egg casings or ‘mermaid’s purses’. Many sharks, rays and skate lay eggs, the cases of which often wash ashore. If you find an egg casing along the seashore, take a photo for Purse Search Ireland, a citizen science project focusing on monitoring the shark, ray and skate species around Ireland.

Another species also found by Irish scientists using the ROV Holland 1 in 2018 was a very rare type of dogfish, the Sail Fin Rough Shark, Oxynotus paradoxus. These sharks are named after their long fins which resemble the trailing sails of a boat, and live in the deep sea in waters up to 750m deep. Like all sharks, skates and rays, they have no bones. Their skeleton is composed of cartilage, much like what our noses and ears are made from! This material is much more flexible and lighter than bone which is perfect for these animals living without the weight of gravity.

Throughout history sharks have been portrayed as the monsters of the sea, a concept that science is continuously debunking. Basking sharks were named in 1765 as Cetorhinus maximus, roughly translated to the ‘big-nosed sea monster’. Basking sharks are filter feeders, often swimming with their mouths agape, they filter plankton from the water.

They are very slow moving and like to bask in the sun in shallow water and are often seen in Irish waters around Spring and early Summer. To help understand the migration of these animals to be better able to understand and conserve these species, the Irish Basking Shark Group have tagged and mapped their travels.

Remarkably, many sharks like the Angel Shark, Squatina squatina have the ability to sense electricity. They do this via small pores in their skin called the ‘Ampullae of Lorenzini’ which are able to detect the tiny electrical impulses of a fish breathing, moving or even its heartbeat from distances of over a kilometre! Angel sharks, often referred to as Monkfish have a distinctively angelic shape, with flattened, large fins appearing like the wings of an angel. They live on the seafloor in the coastal waters of Ireland and much like a cat are nocturnal, primarily active at night.

The intricate complexity of shark adaptations is particularly noticeable in the texture of their skin. Composed of miniscule, perfectly shaped overlapping scales, the skin of shark provides them with protection. Often shark scales have been compared to teeth due to their hard enamel structure. They are strong, but also due to their intricate shape, these scales reduce drag and allow water to glide past them so that the shark can swim more effortlessly and silently. This natural flawless design has been used as inspiration for new neoprene fabric designs to help swimmers glide through the water. Although all sharks have this feature, the Leafscale Gulper Shark, Centrophorus squamosus, found in Ireland are specifically named due to the ornate leaf-shape of their scales.
