O. Sars» and the Soviet Union research vessels «Poisk» and "Akademik Knipovich". Adult capelin was found mainly distributed between 71ºN and 76ºN and between 38ºE and 48ºE and occurred predominantly as scattered registrations with the larger part close to the bottom. This made the conditions for an acoustic abundance estimate unfavourable, and probably only part of the adult capelin present in the area was recorded. The bottom registrations of adult capelin occurred in water with temperatures between -l and 0ºC while the pelagic concentrations of adult capelin were found mainly in temperatures between 0.5 and 2.0ºC. Most of the adult capelin were in the prespawning stage and consisted mainly of the 1970 year-class with some admixture of the 1969 year-class. The majority of the adult fish had a length between 15.0 and 17.5 cm Report Barents Sea Barentshav* Institute for Marine Research: Brage IMR Barents Sea |
