Cod and bovine insulin (2 i.u. kg −1 ) were injected intra‐arterially into cannulated Northern pike, Esox lucius L. and the levels of 13 plasma amino acids analysed by gas‐liquid chroma‐tography after 9 and 48 h. Both insulins caused an equally significant reduction in the level of each amino acid after 9 h which was followed by a recovery to near‐control levels after 48 h. The data support the hypothesis that insulin plays a major role in the regulation of protein metabolism in this species.
