Minister for Agriculture, Food and the Marine, Charlie McConalogue TD, visited the Marine Institute in Galway today and received the Marine Institute’s annual 2022 Fish Stock Book. The detailed annual publication provides the latest impartial scientific advice on the status of 75 key fish stocks of interest to Ireland.

Minister Charlie McConalogue said, "I am delighted to visit the Marine Institute today and to receive the Fish Stock Book for 2022. This provides essential information reviewing the state of fish stocks in 2022 and provides management advice for the setting of quotas for 2023. I am pleased that the work done by the Marine Institute scientists, feeding into the work of the International Council for the Exploration of the Seas (ICES), ensures that decisions we are making at the December Fisheries Council and in negotiations with Third Countries, including the UK, are based on quality data collected over the past year and advice that has been assessed and verified. It is important that the advice and the science underpinning that advice is made accessible to industry and other stakeholders through the continued annual publication of the Fish Stock Book.”

The Minister added. “The 2022 Stock Book is showing a continued gradual increase in the number of sustainably fished stocks. This progress is giving assurance that our policy at national and EU level is making progress on delivering sustainability. Stocks of haddock, monkfish, megrim, tuna, and some of the Dublin Bay Prawn stocks have increased in recent years and continue to be sustainably fished. There are some stocks such as cod, herring and whiting that are overfished and work will continue to set management measures that will support the rebuilding of these important stocks.”

This is the 30th edition of the annual book, which contains the latest management advice used by decision makers to set sustainable catch levels and fishing quotas for 2023. The publication is an invaluable reference guide for a wide audience, including the Minister’s team of negotiators, the fishing industry, marine scientists, environmental NGOs and third level institutes.

In 2021, Irish vessels landed approximately 182,000 tonnes of wild caught fish worth more than €265 million at first sale. This, in turn, supports a valuable processing industry and other activities in our coastal communities.

Ensuring long term sustainability is a key objective of sustainable management of fish stock under the Common Fisheries policy. To that end, every year, the Marine Institute undertakes an extensive data collection programme on multiple scientific fisheries surveys, travelling approximately 23,776 nautical miles over 200 days, equating to 2,030 scientist days at sea on Ireland’s marine research vessels.

Onshore and at sea sampling programmes measure over half a million fish and estimate age for a further 56,000 individuals across all commercial species. Irish data are compiled with that from other countries through the intergovernmental organisation ICES. Marine Institute scientists play a key role in carrying out the assessments and developing the scientific evidence and advice at ICES. The Stock Book integrates the latest scientific advice from ICES with relevant information on Irish fisheries.

Dr Paul Connolly, CEO of the Marine Institute said, "The scientific advice and services provided by our scientists to stakeholders are essential to supporting a sustainable ocean economy, protecting and managing our marine ecosystems and meeting EU obligations. Our scientists participate in, and lead, international working groups that assess fish stocks and provide the independent scientific advice on how many fish can be safely removed from this renewable resource. This work is essential to sustaining the ocean economy for our coastal communities."

Dr Ciaran Kelly, Director of Fisheries Ecosystem Advisory Services at the Marine Institute said, "The arrival of Ireland’s new research vessel, the RV Tom Crean this year, provides us with a state-of-the-art platform to undertake fisheries assessments in Irish waters. The RV Tom Crean and RV Celtic Explorer, enable our scientists to gather the best scientific evidence to help inform important decisions on fisheries management, and ocean sustainability.”

The 2022 Stock Book is available electronically on the Marine Institute's website and as an interactive online application. Most of the scientific work that delivers the Marine Institute's Stock Book is funded under the European Maritime, Fisheries and Aquaculture Fund (EMFAF).

Minister McConalogue was presented with the Stock Book during his visit to the Institute, where he was provided with a series of briefings and demonstrations on the important work of the Institute, including; Seabed Mapping – INFOMAR (Porcupine) linked to the Prawn Underwater TV Survey, Data Collection Framework (DCF) Surveys – Overview of DCF survey programme and spotlight on some of the key surveys involved, Ocean Observations, Climate and Biodiversity – Fisheries Advice (Evolving assessment and advice for shellfish fisheries). Seafood Safety Monitoring Programmes (Phytoplankton Laboratory) and Services to Government relating to regulation of aquaculture activities.

Inland Fisheries Ireland (IFI) has launched a summary report on the findings of fish stock surveys undertaken in all water bodies (lakes, rivers and transitional waters) during 2014. The report, ‘Sampling Fish for the Water Framework Directive’, also outlines the current ecological status of fish stocks in each water body.

IFI has been assigned the responsibility by the Environmental Protection Agency (EPA) to deliver the fish monitoring requirements of the Water Framework Directive (WFD). The fundamental objectives of the WDF are to protect and maintain the status of waters that are already of good or high quality, to prevent any further deterioration, and to restore all waters that are impaired so that they achieve at least a good ecological status.

The fish monitoring programme has been conducted annually since 2007 at specified locations. The second year of the third three-year cycle began in 2014 with an extensive surveillance monitoring programme; 70 river sites, 26 lakes and seven transitional water bodies were surveyed throughout the country.

Dr Cathal Gallagher, Head of Research and Development in Inland Fisheries Ireland, said: “I would like to congratulate all who have contributed to the significant level of work which was undertaken in 2014. This work provides information on the ecological status of fish species present in selected waterbodies as well as information on their abundance, growth and population demographics for fishery managers, legislators, angling clubs, fishery owners and other interested parties”.

Dr Ciaran Byrne, CEO of Inland Fisheries Ireland, commented: “I welcome this summary report of IFI’s fish monitoring programme for the Water Framework Directive. The information captured in the report gives us an increased understanding of the dynamics and changes in our fish populations at sample locations throughout Ireland.”

2014 Report Findings
During 2014, 26 lakes were surveyed with 19 fish species and two types of hybrids identified. A total of 12,205 fish were recorded. Eel was the most common fish species recorded (96 per cent of lakes surveyed) followed by brown trout (81 per cent), perch (65 per cent), roach (42 per cent) and pike (38 per cent).

In general, salmon, brown trout, sea trout and Arctic char were the dominant species in the north, west and south-west of the country. Perch were recorded for the first time in a lake in Donegal. This introduction was illegal and the source is unknown; further investigation will be undertaken by IFI.

Experimental hydro acoustic surveys were carried out on Loughs Caragh, Allen, Melvin, Beagh and Leane to complement the routine surveys. Initial results show that Lough Allen has a large population of pelagic fish, dominated by pollan and juvenile perch; Lough Leane continues to sustain a good population of Killarney shad; Lough Beagh has a healthy Arctic char population; and Loughs Melvin and Caragh continue to sustain small Arctic char populations.

According to the report, 62 per cent of lakes were classified as ‘good’ or better status, with three sites having improved in status since they were last classified. The geographical variation in ecological status reflects the change in fish communities of upland lakes with little human disturbance versus the fish communities of lowland lakes subject to more intensive anthropogenic pressures.

A total of 14 fish species and one type of hybrid (roach x bream) were recorded in 70 river sites (or 50 water bodies) during 2014. A total of 13,480 fish were counted. Brown trout was the most common fish species recorded (96 per cent of sites), followed by salmon (77 per cent), eel (56 per cent), stone loach (50 per cent), minnow (39 per cent), and three-spined stickleback (39 per cent). Sixty per cent of river sites were classified as ‘good’ or better status, with two sites having improved in status since they were last classified.

A total of 50 fish species (or 40,362 individual fish) were recorded across two transitional waters (seven transitional water bodies). The highest number of species recorded in a water body was 29, in the Lower Shannon Estuary. Flounder and sand goby were the most widespread species, while sprat was the most abundant. Some important angling species documented during these surveys included brown trout, European sea bass, salmon, sea trout, pollack and conger eel. Overall both waters achieved ‘good’ status.

#fishstock – The CEO Dr Peter Heffernan of the Marine Institute presented the 2013 Stock Book to the Minister for Agriculture, Food & the Marine Mr. Simon Coveney in today.

The function of the Stock Book is to inform management decisions on fishing opportunities for the Irish fishing fleet in 2014. The Stock Book contains impartial scientific advice developed by the Marine Institute while working with other international scientists. This advice is developed using the latest available research, assessments and advice on the fisheries resource.

The Stock Book forms an important component of the sustainability assessment presented to the Dail annually before the EU fisheries negotiations commence. This year, advice was given for 59 stocks. Results show that 34% of the stocks were fished at sustainable levels, while 24% were fished above these levels and 42% were fished at unknown levels. The EU Commission have stated that the situation continues to improve with 39% of stocks overfished in 2013 compared to 94% in 2003.

"The Stock Book publication is key to our fisheries negotiations with the EU. It is critical I have the latest scientific information and that my decisions are based on sound science that supports sustainable fishing. We are now preparing for the introduction of a discards ban which will apply to stocks such as herring and mackerel from 2015 and to whitefish fisheries from 2016. We need to have regard for changes needed in fisheries management in the lead up to the introduction of the ban and the detailed information in the Stock Book will help us in our preparatory work." said Minister Coveney.

Minister Coveney also stated that "the seas around Ireland are among the most productive fishing areas in EU waters and in 2013, more than 1,040,117 tonnes of fish, with an estimated landed value of €1.161 billion were available to the fleets fishing there".

The Stock Book has been published by the Marine Institute since 1993 and has evolved considerably in that time period. The majority of the scientific advice presented in the Stock Book is formulated by the International Council for the Exploration of the Seas (ICES). The majority of the ICES scientific advice is released in June each year. This is to facilitate consultation with the fishing industry and managers on available fishing opportunities for the coming year.

Peter Heffernan (CEO Marine Institute) stated that "The information contained in the Stock Book represents a huge effort by the Marine Institute to produce the best possible science for the Minister. It is of vital importance to Ireland during the December Fisheries Council meeting"

The Stock Book is also of interest to a wider audience, including the fishing industry, marine scientists, managers, environmental NGO's, third level institutes, financial institutions and those with an interest in the status and management of marine fisheries resources in the waters around Ireland.

The Stock Book is also available electronically on the Marine Institute's web site here

#GALWAY BAY NEWS - Archaeologists in Galway Bay have unearthed an extensive tidal weir complex at Barna and a late medieval quay on Mutton Island, The Irish Times reports.

The weir, which is estimated to date from the early Christian period, consists of a granite barrier with channels cut through it, designed to control the flow of water in the adjacent lagoon.

Connemara archaeologist Michael Gibbons suggests that the weir implies a considerable fish stock migrating through the area into the Barna river.

The remains of a large Iron Age fort which overlooks the site may also have given its name to the townland of Knocknacarra, which is now a populous suburb of Galway.

Meanwhile, further east at Mutton Island a medieval quay which predates the current lighthouse quay has been found.

For all you need on the Marine Environment - covering the latest news and updates on marine science and wildlife, weather and climate, power from the sea and Ireland's coastal regions and communities - the place to be is Afloat.ie.

Coastal Notes

The Coastal Notes category covers a broad range of stories, events and developments that have an impact on Ireland's coastal regions and communities, whose lives and livelihoods are directly linked with the sea and Ireland's coastal waters.

Topics covered in Coastal Notes can be as varied as the rare finding of sea-life creatures, an historic shipwreck with secrets to tell, or even a trawler's net caught hauling much more than just fish.

Other angles focusing the attention of Coastal Notes are Ireland's maritime museums, which are of national importance to maintaining access and knowledge of our nautical heritage, and those who harvest the sea using small boats based in harbours where infrastructure and safety pose an issue, plying their trade along the rugged wild western seaboard.

Coastal Notes tells the stories that are arguably as varied as the environment they come from, and which shape people's interaction with the natural world and our relationship with the sea.

Marine Wildlife

One of the greatest memories of any day spent boating around the Irish coast is an encounter with Marine Wildlife. It's a thrill for young and old to witness seabirds, seals, dolphins and whales right there in their own habitat. And as boaters fortunate enough to have experienced it will testify, even spotting a distant dorsal fin can be the highlight of any day afloat. Was that a porpoise? Was it a whale? No matter how brief the glimpse, it's a privilege to share the seas with Irish marine wildlife.

Thanks to our location in the North Atlantic, there appears to be no shortage of marine life to observe. From whales to dolphins, seals, sharks and other ocean animals, the Marine Wildlife category documents the most interesting accounts around our shores. And we're keen to receive your observations, your photos, links and video clips, too!

Also valuable is the unique perspective of all those who go afloat, from coastal sailing to sea angling to inshore kayaking to offshore yacht racing, as what they encounter can be of great importance to organisations such as the Irish Whale and Dolphin Group (IWDG). Thanks to their work we now know we share the seas with dozens of species who also call Ireland home. But as impressive as the list is, the experts believe there are still gaps in our knowledge. Next time you are out on the ocean waves, keep a sharp look out!

Weather

As an island in the North Atlantic, Ireland's fate is decided by Weather more so than many other European countries. When storm-force winds race across the Irish Sea, ferry and shipping services are cut off, disrupting our economy. When swollen waves crash on our shores, communities are flooded and fishermen brace for impact - both to their vessels and to their livelihoods.

Keeping abreast of the weather, therefore, is as important to leisure cruisers and fishing crews alike - for whom a small craft warning can mean the difference between life and death - as it is to the communities lining the coast, where timely weather alerts can help protect homes and lives.

Weather affects us all, and Afloat.ie will keep you informed on the hows and the whys.

Marine Science

Perhaps it's the work of the Irish research vessels RV Celtic Explorer and RV Celtic Voyager out in the Atlantic Ocean that best highlights the essential nature of Marine Science for the future growth of Ireland's emerging 'blue economy'.

From marine research to development and sustainable management, Ireland is developing a strong and well-deserved reputation as an emerging centre of excellence. Whether it's Wavebob ocean energy technology to aquaculture to weather buoys and oil exploration, the Marine Science category documents the work of Irish marine scientists and researchers and how they have secured prominent roles in many European and international marine science bodies.

Power From The Sea

The message from the experts is clear: offshore wind and wave energy is the future. And as Ireland looks towards the potential of the renewable energy sector, generating Power From The Sea will become a greater priority in the State's 'blue growth' strategy.

Developments and activities in existing and planned projects in the pipeline from the wind and wave renewables sector, and those of the energy exploration industry, point to the future of energy requirements for the whole world, not just in Ireland. And that's not to mention the supplementary industries that sea power projects can support in coastal communities.

Irish ports are already in a good position to capitalise on investments in offshore renewable energy services. And Power From The Sea can even be good for marine wildlife if done properly.

Aside from the green sector, our coastal waters also hold a wealth of oil and gas resources that numerous prospectors are hoping to exploit, even if people in coastal and island areas are as yet unsure of the potential benefits or pitfalls for their communities.

Changing Ocean Climate

Our ocean and climate are inextricably linked - the ocean plays a crucial role in the global climate system in a number of ways. These include absorbing excess heat from the atmosphere and absorbing 30 per cent of the carbon dioxide added to the atmosphere by human activity. But our marine ecosystems are coming under increasing pressure due to climate change.

The Marine Institute, with its national and international partners, works to observe and understand how our ocean is changing and analyses, models and projects the impacts of our changing oceans. Advice and forecasting projections of our changing oceans and climate are essential to create effective policies and management decisions to safeguard our ocean.

Dr Paul Connolly, CEO of the Marine Institute, said, “Our ocean is fundamental to life on earth and affects so many facets of our everyday activities. One of the greatest challenges we face as a society is that of our changing climate. The strong international collaborations that the Marine Institute has built up over decades facilitates a shared focusing on our changing ocean climate and developing new and enhanced ways of monitoring it and tracking changes over time.

“Our knowledge and services help us to observe these patterns of change and identify the steps to safeguard our marine ecosystems for future generations.”

The Marine Institute’s annual ocean climate research survey, which has been running since 2004, facilitates long term monitoring of the deep water environment to the west of Ireland. This repeat survey, which takes place on board RV Celtic Explorer, enables scientists to establish baseline oceanic conditions in Irish waters that can be used as a benchmark for future changes.

Scientists collect data on temperature, salinity, water currents, oxygen and carbon dioxide in the Atlantic Ocean. This high quality oceanographic data contributes to the Atlantic Ocean Observing System. Physical oceanographic data from the survey is submitted to the International Council for the Exploration of the Seas (ICES) and, in addition, the survey contributes to national research such as the VOCAB ocean acidification and biogeochemistry project, the ‘Clean Atlantic’ project on marine litter and the A4 marine climate change project.

Dr Caroline Cusack, who co-ordinates scientific activities on board the RV Celtic Explorer for the annual survey, said, “The generation of long-term series to monitor ocean climate is vital to allow us understand the likely impact of future changes in ocean climate on ecosystems and other marine resources.”

Other activities during the survey in 2019 included the deployment of oceanographic gliders, two Argo floats (Ireland’s contribution to EuroArgo) and four surface drifters (Interreg Atlantic Area Clean Atlantic project). The new Argo floats have the capacity to measure dissolved ocean and biogeochemical parameters from the ocean surface down to a depth of 2,000 metres continuously for up to four years, providing important information as to the health of our oceans.

During the 2019 survey, the RV Celtic Explorer retrieved a string of oceanographic sensors from the deep ocean at an adjacent subsurface moored station and deployed a replacement M6 weather buoy, as part of the Irish Marine Data Buoy Observation Network (IMDBON).

Funded by the Department of Agriculture, Food and the Marine, the IMDBON is managed by the Marine Institute in collaboration with Met Éireann and is designed to improve weather forecasts and safety at sea around Ireland. The data buoys have instruments which collect weather and ocean data including wind speed and direction, pressure, air and sea surface temperature and wave statistics. This data provides vital information for weather forecasts, shipping bulletins, gale and swell warnings as well as data for general public information and research.

“It is only in the last 20 years, meteorologists and climatologists have really began to understood the pivotal role the ocean plays in determining our climate and weather,” said Evelyn Cusack, Head of Forecasting at Met Éireann. “The real-time information provided by the Irish data buoy network is particularly important for our mariners and rescue services. The M6 data buoy in the Atlantic provides vital information on swell waves generated by Atlantic storms. Even though the weather and winds may be calm around our shores, there could be some very high swells coming in from Atlantic storms.”
