Experts in shark biology, data and mapping recently met at the Marine Institute’s headquarters in Oranmore, Co Galway to map the distribution of deepwater sharks, skates and chimaeras in the North-East Atlantic Ocean.

Scientists and marine experts at the International Council Exploration of the Seas’ (ICES) WKSHARKS Workshop analysed decades of data from research surveys in the North Atlantic Ocean.

This included nearly 30 years of data collected by Irish scientists on board the Marine Institute’s RV Celtic Explorer and commercial vessels.

The WKSHARKS Workshop included experts from Ireland, the United Kingdom, Portugal, France and Denmark, with other experts contributing remotely from Norway, Iceland and the Netherlands.

And their aim was to produce maps that indicate the area and depth of 25 species of deepwater sharks, skates and chimaeras — information that will assist in understanding the range and habitat of these marine wildlife species, underpinning future management decisions.

It will also be considered by the Convention for the Protection of the Marine Environment of the North-East Atlantic (OSPAR) and the North-East Atlantic Fisheries Commission (NEAFC) to determine future action to sustainably manage these populations.

These two organisations have a joint interest in the open North Atlantic, while ICES scientists have unique knowledge of the deepwater fisheries and species in this area, which focuses on waters off Ireland, Portugal and Iceland.

Maurice Clarke, fisheries scientist at the Marine Institute and WKSHARKS Workshop chair, said: “Sharks and rays have an important function in maintaining balanced and healthy marine ecosystems. Providing scientific advice is essential to protecting these marine species in the North-East Atlantic.

“For many of these species, this is the first time that data from European surveys is being collated and analysed for this purpose.”

Irish waters are home to 71 species of sharks, skates, rays and chimaeras. These species include some of the latest maturing and slowest reproducing of all vertebrates, resulting in very low population growth rates with little capacity to recover from overfishing and other threats such as pollution or habitat destruction.

ICES received a joint request from the Convention for the Protection of the Marine Environment of the North-East Atlantic (OSPAR) and the North-East Atlantic Fisheries Commission (NEAFC) to develop distribution maps of deep-sea sharks, rays and skates, and also to advise on methods of mitigating bycatch of these species.

To track Atlantic salmon movements from river to sea and back, millions of salmon have been tagged over the past 50 years as part of scientific international tagging programmes.

Recently, ICES published a co-operative research report documenting 50 years of marine tag recoveries from Atlantic salmon, and marking 2019’s declaration as International Year the Salmon.

Programmes have included tagging of smolts, migrating out from their freshwater nurseries to the sea and their recaptures in high-seas fisheries off Norway and the Faroes, in coastal fisheries around Greenland and upon return to home waters.

Other studies included tagging of adults caught at sea and their subsequent recaptures in home waters in coastal fisheries and by anglers.

“Tagging and related data efforts are crucial as scientists seek to improve understanding of wild Atlantic salmon distribution and migration at sea and the underlying causes of mortality,” said Niall O'Maoileidigh of the Marine Institute.

“This is particularly important given that, despite initiatives that have mitigated some declines, abundance of the species has continued to drop in the last two decades.”

Tagging has included various types of external ‘floy tags’ focusing in the past 20 years on coded wire tags, less than 2mm in length and delicately implanted into the nose cartilage of fish.

This report not only documents the history of these tagging programmes for posterity but also investigates migration patterns, timings, return rates, their changes and patterns.

“Mass marking techniques still provide basic information on survival rates, exploitation rates and migration in general. However, with current technology e-tagging is becoming far more informative, giving rise to information not only of the ‘when and where’ of tagging-releases and recaptures, but also on the movements, routes, depths and behaviours in-between,” O’Maoileidigh added.

Earlier this week Ireland’s first salmon of 2019 was caught and released on New Year’s Day in Co Donegal.

#MarineScience - Dr Colm Lordan of Fisheries Ecosystems Advisory Services at the Marine Institute has been appointed as one of the Vice Chairs of the International Council for the Exploration of the Sea (ICES) Advisory Committee.

The ICES Advisory Committee (ACOM) is responsible for providing scientific advice to competent authorities in support of the sustainable management of marine resources and ecosystems in the North Atlantic Ocean. Dr Lordan will work 50% of the time in his new ACOM role and 50% in his team lead role at the Marine Institute.

Dr Lordan joined the Marine Institute in 1998 and participated in Northern Shelf and Southern Shelf demersal stock assessment working groups.

In 2003, his focus moved to nephrops stocks and developing underwater television surveys and assessment methods. Dr Lordan currently leads a team of marine scientists working on demersal fish and nephrops surveys, stock assessment and scientific advice.

Dr Lordan said he is expecting his three-year term as Vice Chair of the ICES Advisory Committee to be both busy and diverse.

“I am looking forward to getting a broader perspective on the advisory system and I hope to learn a lot about stocks, fisheries, assessments, and management challenges in areas beyond the Celtic Seas,” he said.

“I am also interested in collaborating with others to improve the quality assurance and to develop new and innovative advisory products.”

Dr Lordan was first involved with ICES in 1993, and since then has participated in 60 different ICES expert groups and chaired or co-chaired 16 working groups.

ICES has a network of more than 5,000 scientists from over 690 marine institutes in 20 countries. For more information on ICES visit www.ices.dk.

The Marine Institute's specialist research library, Oceanus with has over 5,000 books relating to marine, natural and life sciences is now open online. The institute's extensive collection of scientific literature relating to marine and freshwater resources is available to browse in advance of visiting the library in person to access the material.

Some rare items date back over one hundred years and in the collection which includes contributions from the Fisheries Branch until the Fisheries Research Centre moved to Abbotstown in the 1970s and was incorporated into the Marine Institute in January 1996. The library has built up a fine collection of resource material to support and assist research, development and innovation in the marine sector.

"The foundations of the Marine Institute Library collection began with materials acquired by the Fisheries Branch of the Department of Agriculture and Technical Instruction for Ireland, which was established in 1899," said Dr. Peter Heffernan, Chief Executive of the Marine Institute.

According to Anne Wilkinson, the Institute's Library and Information Manager, "Our unique archive material, dating from c. 1890, is an important element of this collection. The archive includes scientific reports, books and publications prepared by Irish and international marine researchers, including copies of Fishery Ireland Acts dating from the late 1800s and Reports of the Inspectors of Irish Fisheries and Sea and Inland Fisheries Ireland from the same period."

The Library archive has a microfiche reader to facilitate access to some of this material. In addition there are many research reports prepared by Marine Institute scientists and marine related publications issued by the EU, the International Council for the Exploration of the Sea (ICES), and the Food and Agriculture Organisation of the United Nations (FAO).
