Distribution and growth of capelin in the Barents Sea in relation to water temperature in the period 1974 to 1983
The variation in the distribution of the different age-groups of capelin in the Barents Sea were studied in relation to temperature variation in the period 1974 to 1983. In addition, growth of the capelin were compared to the temperature data for the years 1977 to 1983. The data were collected on ye...
