#Angling - Inland Fisheries Ireland (IFI) is currently carrying out a fish stock survey on Lough Ennell, near Mullingar, to assess the current status of the fish populations in the lake.

The survey takes place from today (Tuesday 19 September) till the Friday (22 September) and will involve netting throughout the lake undertaken by IFI staff from Limerick and research staff from Citywest headquarters crewing a total of two boats.

It’s expected that the survey will provide a range of information on the fish stocks in the lake, such as size distributions of fish captured, age and growth information for all species, diet of selected species, and catch per unit effort (CPUEs) for each fish species.

Samples for genetic analyses of brown trout and pike will also be taken. The information collected will assist IFI in managing, conserving and monitoring any changes in the fish stocks of the lake.

The survey crews will be very visible on the lake and all sets of nets will be marked with distinctive buoys labelled ‘IFI Survey’. Any anglers or other lake users are asked to be vigilant if out and about on the lake to avoid snagging in the nets.

Further details on the background of this survey are available on the IFI website.

#Fishing - Dr Peter Heffernan, CEO of the Marine Institute, presented the Minister for the Marine Simon Coveney with The 2012 Stock Book ahead of the EU Fisheries Council negotiations next week, noting an improvement in certain fish stocks with a higher number of stocks sustainably fished in 2012 compared with 2011 - as Tom McSweeney writes about in his column last Friday.

The Stock Book gives an overview of 59 stocks from which Ireland has an EU quota allocation and will be used to inform discussions and decisions on Total Allowable Catches (TACs) fishing quotas for 2013. TACs and quotas will be decided at the December EU Fisheries Council on 18-20 December which will be attended by the minister, who has lately faced criticism over the proposed deep-sea salmon farm in Galway Bay.

Minister Coveney said: "I welcome the comprehensive review carried out by the Marine Institute showing the state of fish stocks that are of importance to Ireland. Of the 59 stocks in which Ireland has a share of the EU TAC, 42% are now fished sustainably compared to 36% in 2011. The state of the resource base in terms of the biomass, the population of mature fish in the stock, has also improved. The number of depleted stocks has declined from 12 to 8.

"It is good to see progress on delivering sustainable fishing. Further efforts are needed both in terms of setting TAC levels and also taking other measures such as reducing catches of juvenile fish and dealing with unacceptable levels of discards.

He added: "Having the latest scientific information at my fingertips is essential at the December council. My approach to the negotiations will be to utilise this science to ensure EU fishing policy secures the long term sustainability of the industry.

"The December Council negotiations must concentrate on achieving a more practical and pragmatic regime for the fishing industry, grounded in the scientific data available in the Stock Book.”  

The Stock Book advice is developed using the latest available research, assessments and advice on the fisheries resource. Irish scientists collaborate with other international scientists at the International Council for the Exploration of the Seas (ICES).  

“ICES is a key forum for Ireland where our scientists develop impartial scientific advice that meets best international standards,” said Dr Heffernan.  

The Stock Book is presented annually to Department of Agriculture, Food and the Marine. The information is of vital importance in serving Ireland during the annual TAC negotiations at the various EU Council of Fisheries meetings, but principally at the December council meeting where the quotas for the following year are set.

It is also of interest to a wider audience, including the fishing industry, marine scientists, managers, environmental NGOs, 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 has been published by the Marine Institute since 1993 and has evolved considerably in that time period.  It continues to evolve in a changing fisheries advisory environment. The Stock Book is available electronically on the Marine Institute’s website HERE.

#ANGLING - Plans to bring forward the estuary draft net season "would have a detrimental effect" on spring salmon stocks, writes Derek Evans in The Irish Times today.

Evans was responding to proposals before Minister of State for Natural Resources Fergus O'Dowd to extend the draft net season from its current start date of 12 May to mid-April.

"At a time when we are beginning to see the benefits of the 2006 drift net closure coming to fruition in terms of salmon returning to our lakes and rivers," he writes, "is it not absolutely unreasonable to even consider such an application?"

He referred to anglers who have "played their part" by sticking to a "suite of regulations" introduced by the State in an effort to conserve river stocks, which include a doubling of the salmon licence fee and an annual bag limit restricted to 10 fish.

Spring salmon angling is also a significant attraction for tourism, he suggests, and any threat could damage that business.

The minister's office has issued a statement saying there no proposal currently under consideration to bring forward the start date.

#ANGLING - Northern Ireland river anglers are taking a novel approach to lobbying Stormont over salmon exploitation by harnessing the power of social networking.

According to the News Letter, the NoSalmonNets campaigners "have swapped their fishing rods for laptop computers", using Facebook to attract support for their campaign to bring an end to the offshore netting of wild salmon stocks.

As previously reported on Afloat.ie, Northern Ireland's Department of Culture, Arts and Leisure (DCAL) has called for a voluntary ban on offshore salmon fishing, following new research that shows a significant drop in their numbers in the North's rivers.

Seamus Donnelly of NoSalmonNets has welcomed DCAL's recent decision to stop issusing licences for commercial salmon nets that may "contravene European law" off Antrim's north coast, made in an effort to protect salmon stocks in the Foyle river system.

Donnelly explained that the campaign was borne from frustration at the apparent inaction by the NI Executive over the protection of salmon.

“One of the keys to our success has to be Facebook," he said. "The internet has an unlimited reach and we took advantage of that.”

#INLAND WATERWAYS - Inland Fisheries Ireland (IFI) has announced the results of studies on the genetic makeup of brown trout stocks in the Suir and Boyne river catchments.

These studies form part of a wider scheme looking at Ireland's larger riverine catchments - assisted by the Office of Public Works, geneticists from UCD and trout anglers across Ireland - and involve a chemical analysis of scale samples from fish known as 'micro-satellite DNA analysis'.

The results from the Suir and Boyne are described by IFI as "quite amazing" and "of significant value" to managing the fisheries in these areas.

In both catchments, the first step saw trout stock samples of young fish examined genetically, and they were shown to be discrete - in other words, fish from any given tributary were found to be genetically different to those from others.

The next step involved samples of adult fish from the main river, contributed by anglers, which were then related to the different tributary genetic types.

Summary results from the Suir and Boyne show that there are respectively seven and five distinct families of trout in the catchment area; that most fish born in tributaries migrate to the main stem till adulthood before returning to their tributaries to spawn; that numbers migrating from individual tributaries are variable, but fish don't cross into adjacent catchment areas; and that there movement of young trout along the river system is "extraordinary", with fish often migrating from near the source to the mouth.

More details on findings for the Suir catchment and Boyne catchment are available on the IFI website.

#FISHING - The Minister for the Marine has spoken out over plans by the European Commission to make cuts in certain fish stocks that could see €65 million in lost earnings for Ireland's fishing fleet.

According to The Irish Times, Minister Simon Coveney said there was "very credible data prepared by the Marine Institute to back up" the case against proposals by EU maritime affairs commissioner Maria Damanaki to cut certain stocks by as much as 25%.

He told the paper he would "challenge anyone to say we are not sticking with scientific advice", and also suggested that the fishing industry is being more responsible in its own proposals.

"The European Commission is recommending a 60 per cent increase in the total allowable catch for Celtic Sea herring, whereas the industry is seeking 30 per cent as a more responsible approach,” said Minister Coveney.

“So this shows it is not true to say that fishermen are irresponsible, as some would suggest."

EU fish talks continue today in Brussels. The Irish Times has more on the story HERE.

The Marine Institute's two research vessels, RV Celtic Explorer and RV Celtic Voyager are to lead Europe with an all-time record of 627 days spent at sea of between both ships, well above the average for equivalent European research vessels.
In 2011, the RV Celtic Explorer is scheduled for 17 surveys in Irish waters resulting in 344 days at sea and the RV Celtic Voyager with 29 surveys resulting in 283 days at sea. In comparison, in 2010 the RV Celtic Explorer spent 308 days at sea with 18 surveys and as well as undergoing a refit. The Celtic Voyager took 280 sea-going days resulting in 32 surveys.

These figures compare favourably with our European counterparts, reflecting a high level of activity on national and international research and monitoring programmes.

Work duties in 2011 for the Galway based vessels will range from fisheries surveys to underwater mapping and from climate studies to deepwater surveys with the remotely operated submersible ROV Holland 1. The work schedule will facilitate training missions and to carry out essential maintenance work on Ireland's network of data buoys that, in parallel to their research function, supply the vital information on which weather and shipping forecasts are based.

The increased activity of the research vessels reflects the growing imperative to understand and sustainably manage the economic potential of our offshore marine territories, an area over ten times that of Ireland itself.

A major role of the ships' workload will be commercial fish stock assessments. Together they are to devote 141 days on stock surveys in support of the sustainable management of Ireland's fisheries.

The RV Celtic Voyager will conduct underwater television surveys of valuable prawn stocks off the Aran Islands, the Irish and Celtic Seas, working on blue whiting, a survey of herring stocks in the north-west. In addition a comprehensive 54-day annual Irish Groundfish Survey which will take place in stages all around the Irish coast from September to December.

The survey will be the largest undertaken by an Irish research vessel and is essential to providing the scientific data used to inform the annual quota negotiations required in Brussels each year.

For the 2011 schedule for both vessels is available to view by clicking HERE and the Maritime Institute website click this link.

At 65.5m RV Celtic Explorer (2,425grt) accommodates 35 personnel and up to 21 scientists and 31.4m RV Celtic Voyager (340grt) with up to 8 scientists and a maximum endurance of 14-day days.

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.”
