dc.description.abstract | Stomach content samples from 92 minke whales Balaenoptera acutorostrata,
caught during scientific whaling operations in July-August 1992,
were collected in five selected areas in Norwegian and adjacent
waters. Preliminary results from the stomach analyses indicate
a diet almost completely dominated by fish, although there was
considerable heterogeneity in species composition between the
areas. Capelin dominated the minke whale diets in the two
northernmost study areas (Spitsbergen and Bear Island). Further
south, in coastal areas of North Norway and Russia, herring was
the most important food item, but was accompanied by significant
amounts of sand eel, cod, haddock and saithe. A survey aimed to
locate and classify fish and plankton resources was conducted
simultaneously with the scientific whaling program. The northern
areas were particularly dominated by 0-group cod (which was not
found in whale stomachs), while capelin abundance was recorded
only sporadically. Along the coast of North Norway and Russia,
there appeared to be a larger degree of similarity between prey
abundance and minke whale diet. Herring was documented to be very
abundant both in the resource surveys and in the whale stomach
analyses. The similarity in distribution was particularly
conspicuous for 0-group herring. | no_NO |
