Investigations on demersal fish in the Barents Sea winter 2005 : detailed report
A combined acoustic and bottom trawl survey to obtain indices of abundance and estimates of length and weight at age has been carried out each winter (4-6 weeks in January-March) since 1981 in the Barents Sea. The target species are cod and haddock, but abundance indices have also been worked out fo...
