Assessing trawl-survey estimates of frequency distributions
(ICES CM Documents;2000/K:23, Working paper, 2000)Marine trawl surveys catch a cluster of fish at each station and fish caught together tend to have more similar characteristics, such as length, age, stomach contents etc., than those in the entire population. When this ... -
Behavioural rhythm of cod during migration in the Barents Sea
(ICES CM Documents;2000/K:34, Working paper, 2000)To assess fish abundance by direct methods and to understand and model species interaction, it is important to have proper knowledge about behavioural patterns. Patterns in vertical distribution might strongly affect ... -
Fisheries management in the Barents Sea
(ICES CM Documents;1999/Q:1, Working paper, 1999)The fisheries in the Barents Sea are of very high importance to the region. Most of the fish stocks are shared by Norway and Russia and joint management decisions are taken by The Joint Norwegian-Russian Fisheries ... -
