Diet composition for three sciaenids caught off northeastern Brazil

Larimus breviceps, Isopisthus parvipinnis, and Paralonchurus brasiliensis are the 3 most abundant species of Sciaenidae in the Marine Extractive Reserve of Corumbau in Bahia (northeastern Brazil). Ontogenetic and seasonal changes in the diet of these species were analyzed. These changes may reflect...
