Survey report from the joint Norwegian/Russian acoustic survey of pelagic fish in the Barents Sea September-October 2001

The survey was carried out in the period 3rd of September to 4th of October 2001 and was terminated by a meeting in Vadsoe 5-7th October. The main aim of the survey was to estimate the sizes of two pelagic fish stocks in the Barents Sea, the capelin and the polar cod, in addition to studying their biology and geographical distribution. An estimate was also made of a third pelagic species in the area, the young herring. The survey on pelagic species formed a part of a multipurpose survey, with aim to study fish, environmental features, and plankton. On "Johan Hjort" acoustic experiments on capelin avoidance towards vessel noise were done
