Sammendrag
Except for 1972, investigations on the Barents Sea capelin stock
have been carried out within the period 10 September - 15 October
since 1971 by the Institute of Marine Research. These investigations have revealed
variations in the geographical distribution of capelin during the period 1971-80. The present paper concentrates on the influence of temperature on the capelin distribution. The influence of ice is also briefly discussed.
The distribution area of capelin, north of 76°N and between the meridians 27°E and 55°E, is compared with the temperature at 100 m and ice conditions in the same area. The relation between temperatures and northerly distribution of capelin is fairly good, while there is no relation between ice conditions and capelin distribution.
The results also indicate that 3 and 4 years old capelin prefer water colder than 2°C.
