TROPHIC INTERRELATIONS OF THE THREE MOST ABUNDANT FISH SPECIES FROM LAGUNA SAN IGNACIO, BAJA CALIFORNIA SUR, MEXICO

摘要

We analyzed the trophic interrelations of cominate sea catfish Arius platypogon, shortfin weakfish Cynoscion parvipinnis, and California king croaker Menticirrhus undulatus from Laguna San Ignacio, B.C.S., Mexico during spring and summer 1992. Four differ- ent trophic groups were found on the basis of feeding preferences; crustaceans, fish, mollusks, and polychaetes. Each predator species has a preference for specific prey.
