California Fish and Game, 74, pp. 49-54. Comments: The Amphipod Corophium salmonis is the most important prey for juvenile (Emmett et al., 1993). Adults feeds on Amphipods: Corophium salmonis, Corophium spinicorne and Eogammarus spp., and fishes especially Engraulis mordax, insects, primarily chironomid and heleid larvae, and the mysid Neomysis mercedis. Also Bivalvia, Crangonidae, and Isopoda are eaten principally (Muir et al., 1988). |
