The results of a stratified random bottom trawl survey with R/V "Michael Sars" in May 1985 in the Barents Sea between N71°30' N75°30' and between E25°30' - N35°30' is described in this report. It also describes the results from a survey with the same vessel in the Barents Sea between N75°30' - N76°35' and between E25°30' - E35°00', between N73°00' - N74°10 and between E16°30' - E25°30' and in the Svalbard region between N74°00' - N80°30' and between E8°00' - E18°00' in July -August 1985. On the basis of the data from 119 trawl stations, the biomass of shrimps, Pandalus borealis, in the Barents Sea survey was estimated to be about 218 000 tonnes. In Spitsbergen area the biomass of shrimps was estimated to be about 35 000 tonnes on the basis of data from 72 trawl stations. By-catch data for fish are also given and discussed.
