Isopisthus parvipinnis, Sciaenidae, Stomach content, Feeding, Baía de Santos, Brazil
Abstract
Stomach contents of 688 specimens of Isopisthus parvipinnis from Baía de Santos (SP) sampled between June/76 and April/77 were examined. The relative importance of different components of the diet was expressed as percentage frequency of occcurrence, percentage number, and feeding index proposed by Kawakami & Vazzoler (1980). The most frequent and abundant items were Teleostei and Decapoda Natantia. The relative proportions of the main dietary items exhibited seasonal variations. Also, dietary changes may be linked to growth.
