As part of a biological investigation of important demersal fish
species, stomachs have been taken from cod, haddock, saithe and a few
other species in 1982 and 1983. Also observations of stomachs have
been made in the field. Some of the data from this sampling programme
are presented in this paper. Data have been collected in spring, when
the spawning of cod and herring take place and in summer. The
stomachs have been preserved one by one together with data on each
individual fish. In 1982 the stomachs were mainly put on formalin but
in 1983 they were frozen. Data collected together with the stomachs
are length, weight, age, sex and maturity. For cod also an index
describing them as coastal or oceanic type have been given by otolitt
readings. The stomach content have been analyzed for important prey
groups. Tables showing total stomack content both in numbers and
weight and devided on the various prey categories are given. A
distinct seasonal shift in preference of prey is illustrated.
