Atlantic Salmon, Sea Trout & Eels

Salmon, sea-trout and eels belong to the group of fish which live for part of their lives in freshwater and part in the ocean. In the case of salmon and sea trout, these fish migrate from the seas where they have been feeding and return to spawn in the rivers in which they themselves were spawned. In contrast, eels spawn in the ocean, returning to rivers and lakes to feed and grow.

All three are vitally important to Ireland from an economic and cultural perspective. In recent times the number of these fish in our waters has declined.

Role of Marine Institute, Newport

The Marine Institutes role is to investigate the causes of these declines by developing a deeper understanding of the complex biology of these fascinating animals. In this way we can provide scientific advice which will slow down or halt this decline and more importantly restore these stocks to safe biological levels and allow sustainable fishing for commercial and recreational fishermen.

Operational Programmes

This task has been mandated under the Marine Institute Act, 1991 and is carried out to meet Ireland's obligations under a series of international treaties such as the Oslo Paris for the Protection of the Marine Environment of the North East Atlantic and the Rio Declaration of 1991. The Marine Institute is committed to working with other Irish researchers to disseminate data and to build public awareness of marine environment issues.


Foreign Vessel Surveys

To investigate spatial distribution and collect biological information on Irish Sea gadoids. To conduct a trawl survey to estimate the abundance & distribution of anglerfish. Bottom Trawl Survey targeting juvenile gadoid species. North and West of Ireland.


Infomar- Introduction to Seabed Surveying at the Marine Institute

The data will be of interest to fisheries managers, aquaculture operators, coastal zone managers and engineers, offshore engineering interests, licensing authorities and those carrying out environmental impact assessments. Covering some 125,000 square kilometres of underwater territory, INFOMAR project will produce integrated mapping products covering the physical, chemical and biological features of the seabed.
