Abstract
From 1984 to 1988 the average weight of cod (Gadus morhun) by age group in the
Northeast Arctic stock was reduced by about 60% in most age groups. During the
same period, the estimated individual food consumption by age group has decreased
by 40-70%. It is concluded that these two features are closely correlated and that the
decimation of the stock of one of the major prey species, the capelin (Mallotus
villosus), is ultimately largely responsible.
