Description
Summary:Rapporten er også publisert som artikkel i Fiskets Gang,61(8),1975:101-104 During September-October 1974 observations were made on the distribution, abundance and year-class composition of capelin in the Barents Sea. Specifically it was of great importance to get an abundance estimate of the 1975 spawning population. Dense concentrations of capelin were found over a larger area than at the same time in 1973. The total population was estimated to be essentially larger than in 1973. l and 2 years old capelin showed reduced growth compared to «normal». As a result, the proportion of 2 years old capelin that is maturing, is also lower than «normal». Besides this, the abundance of 3 years old fish is found to be rather low and consequently the total spawning population will be reduced.
