The annual Irish Groundfish Survey (IGFS) off the Atlantic coastline of Ireland is now under way for 2026 and will continue to Wednesday 18 November, subject to operational and weather constraints.
The IGFS is a demersal trawl survey carried out by the Marine Institute, consisting of some 170 fishing hauls of 30 minutes duration each in International Council for the Exploration of the Sea (ICES) areas Vla, Vllb, Vllg and Vllj, in fulfilment of Ireland’s Common Fisheries Policy obligations.
The approximate locations of the shooting position of these hauls are set out in the tables in Appendix 1 and a map indicating each position is available in Appendix 2 to Marine Notice No 48 of 2026, attached below. Fishing in the 2025 survey will take place within a two-nautical-mile (2 nmi) radius of these indicative positions.
The survey will be conducted by the RV Celtic Explorer (callsign EIGB). The vessel will deploy a high headline GOV 36/47 demersal trawl during fishing operations, and will display appropriate lights and signals.
The Marine Institute requests that commercial fishing and other marine operators keep a 2nmi area around the tow mid-points clear of any gear or apparatus during the survey period outlined above.
Further details, including a map and coordinates of the trawl survey area and contact information, can be found in the Marine Notice attached below.
