Diet of four serranid species from the Senegalese coast (eastern tropical Atlantic)

Abstract

       Data on the diet of four serranid species with high commercial value, caught off the Senegalese coast, were determined by analyzing stomach contents. The studied fishes were the white grouper Epinephelus aeneus, the golden grouper E. costae, the dusky grouper E. marginatus and the comb grouper Mycteroperca rubra. The coefficient of vacuity and other dietary parameters were calculated. The four species fed mainly on teleosts but also on crustaceans and cephalopods, including the common Octopus.
