Results of a stratified bottom trawl survey for shrimps (Pandalus borealis) in the Barents Sea and the Spitsbergen area in May-June 1980.

A stratified random bottom trawl survey of the shrimp grounds in the Barents Sea and the Spitsbergen area between 71°30'N and 78°18 'N, and between 10°05 'E and 35°04 'E was made in May-June 1980. On the basis of the data from 60 trawling stations, the biomass of shrimps, Pandalus borealis, in the area surveyed was estimated by the swept area method to be about 65 000 tonnes. The estimate is probably an underestimate due to various reasons discussed
