Report 2 of the Study Group on Red-fish Stocks (SGRS) ...
A trawl-acoustic survey on pelagic redfish (Sebastes mentella) in the Irminger Sea and adjacent waters was carried out by Germany, Iceland and Russia in June/July 2005. Nearly 400 000 nm2 were covered. A total biomass of 551 000 t was estimated at depths shallower than the “deep scattering layer” (D...
