The Irish Groundfish Surveys is part of an annual International Bottom Trawl Survey (IBTS) programme co-ordinated by the International Council for the Exploration of the Sea (ICES). The survey is carried out over 47 days between October-December each year by the Marine Institute and collects demersal trawl and ancillary data in Irish waters to produce relative abundance indices for fisheries management in the Northwest Atlantic Shelf waters.

The survey is carried out over 47 days between October-December each year by the Marine Institute and collects demersal trawl and ancillary data in Irish waters to produce relative Abundance indices for fisheries management in the Northwest Atlantic Shelf waters. In addition to the commercially exploited fish, elasmobranch, cephalopod and crustacean species, and an amount of macroinvertebrate species are also caught. These are sampled in a similar way to the groundfish, identified by species (or higher taxa where not practical to ID at sea), and total weight as well as total as well as recorded where possible. An internal review of this data was undertaken in 2019 to check for Spatial and Temporal consistency in Abundance and Taxonomy with the standardised data set being made available here.

The Irish Groundfish Survey forms part of the International Bottom Trawl Survey (IBTS) programme, an international survey effort coordinated by ICES (the International Council of the Exploration of the Sea). Over 42 days in the Autumn/Winter each year the survey collects demersal trawl and ancillary data in Irish waters to produce relative abundance indices for fisheries management. The Irish Groundfish Survey (IGFS) in its current form commenced in 2003 on the 65m research vessel, the R.V. Celtic Explorer. In Irish waters currently, France and Ireland cover the Celtic Sea area, Ireland covers the shelf West of Ireland, Ireland and the UK Scotland cover the north coast of Ireland and the UK Northern Ireland covers the Irish Sea.
