Some observations on the feeding ecology of Norwegian spring spawning herring (Clupea harengus) along the coast of Norway
The feeding ecology of Norwegian spring spawning herring Clupea harengus was studied with samples collected from cruises in February -March 1991, May 1992, and February and April 1993. A wide variety of zooplankton organisms were observed in the diet of herring, with crustaceans dominating except in...
