Peculiarities of spring feeding by capelin (Mallotus villosus) on the Grand Bank in 1987–90
The comparative feeding characteristics of immature and mature capelin (Mallotus villosus) on the Grand Bank (NAFO Divisions 3LNO) during 1987–90 in April and May are presented. Copepods, mainly Calanus finmarchicus, were the main food for immature capelin. Areas of intensive feeding on copepods wer...
