Teleosts (97%) were the most important prey regarding the frequency of occurrence values, followed by cephalopods (59.2%), and crustaceans (5.8%). In total, 1230 individuals (1001 teleosts, 220 cephalopods, nine crustaceans) belonging to 34 species (15 teleosts, 18 cephalopods, one crustacean) were identified.
