Description
Summary:The Institute of Marine Research (IMR), Bergen, has carried out combined bottom trawl and acoustic surveys for cod in the Barents Sea since 1981. Commercial statistics are collected routinely for this area through the Directorate of Fisheries; the Institute collects length and age samples of these landings. Also, the Institute of Fishery Technology Research conducted studies of cod-end selectivity for Norwegian bottom trawlers in the Barents Sea during 1989. These data are readily available and represent the most comprehensive information describing the condition of the stock, and the prosecution of the Norwegian bottom trawl fishery.
