Sammendrag
The variations in the distribution and abundance of the different age groups
of capelin in the Barents Sea were studied in relation to temperature variations
in the period 1974-1982. The data were collected on yearly cruises in September-
October .
During the period 1976-1980 a pronounced south- and westward displacement of
all age groups was observed. The displacement coincides with decreasing water
temperatures in the region, and it is shown that the older age groups, 2, 3
and 4 years old fish, inhabited significantly warmer water masses in the years
1980-1982 than previously. The mean weight of the fish, especially for the 2
years old, changed correspondingly, as it was higher in 1980-1982 than previously
in the period.
