The paper describes diet variation of cod and haddock at a spawning ground
of the Norwegian Spring Spawning Herring. Samples were collected at bimonthly
intervals through a one-year period, including during and following
the spawning season of herring in March-April.
The significance of herring and herring eggs is analysed in relation to the
diet of the two demersal species during the remainder of the year. Both
species show strong diet shifts when herring or herring eggs appear in the
area.
