Description
Summary:We analyzed stomach content of blue whiting in the Barents Sea in February-March 2002 and 2006, and in August-September 2005. Krill was the most important prey for blue whiting in the Barents Sea, and constituted about 90% of diet in winter and 50% in summer. Blue whiting also fed on amphipods and fish, including blue whiting. Copepods, an important group of prey for blue whiting in the Norwegian Sea, was unimportant in the diet in the Barents Sea. NORSK SAMMENDRAG: Vi undersøkte dietten til kolmule i Barentshavet i februar-mars 2002 og 2006, og i august og september 2005. Krill var det viktigste byttet til kolmula i Barentshavet, og utgjorde ca 90% av diett om vinteren og ca 50% om sommeren. Kolmula spiste også amfipoder og fisk, inkludert kolmule. Hoppekreps som er viktig for kolmula i Norskehavet, utgjorde en ubetydelig andel av dietten.
