DEMERSAL FISH COMMITTEE 1992 Report of Activities

Recording of densities and growth rates of the 1991 and 1992 year classes of sole, plaice, dab, flounder and whiting was carried out. Two cruises were therefore undertaken according to the criteria of the International Demersal Young Fish Survey. The beamtrawl survey was continued in order to estimate the stock size of adult flatfish in the Southern North Sea by means of beamtrawl fishery in August. This was part of an international survey in collaboration with the Dutch and UK institutes. The market sampling was continued covering sole and plaice (North Sea-English Channel-Celtic Sea and Irish Sea), cod (North Sea) and whiting (North Sea).
