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. Results from 2014 are presented here and suggest a significant increase in numbers of juvenile haddock and whiting over the recent 5 year period in the northwest. In the Celtic Sea area horse mackerel numbers also show an increase. The other gadoid and pelagic species are within the normal inter-annual fluctuations.
