Abstract
The feeding habits of spearnose grenadier (Coelorinchus multispinulosus) were studied using 361 specimens collected from January to December 2005~2006 in the coastal waters off Gori, Korea. The size of C. multispinulosus ranged from 1.5 to 8.5 cm in anal length (AL). C. multispinulosus was crustacean feeder that consumes mainly consumed shrimps and amphipods. Its diet also included small quantities of copepods, mysids, cumaceans, stomatopods, crabs, polychaetes and fishes. C. multispinulosus mainly consumed shrimps in all size classes and seasons except the smallest size class in summer which mainly consumed amphipods. Smaller individuals secondly consumed amphipods, copepods and mysids, and the portion of these prey items in the total diet decreased as body size.
