Dietary Analysis of Batfishes (Lophiiformes: Ogcocephalidae) in the Gulf of Mexico


Stomach content analyses, performed on three species of batfishes, Halieutichthys aculeatus, Ogcocephalus declivirostris, and Ogcocephalus pantosticus collected in the Gulf of Mexico in summer (June-July) and fall (Oct.-Nov.) 2002 and 2003, revealed a variety of benthic invertebrates, particularly gastropods, polychaete worms, and xanthid crabs. Schoener's dietary overlap indices (Sl) were calculated between the three species within the same seasons, and within each species between seasons. SI values indicated that each species consumed a different assemblage of prey and that two of the species exhibited temporal variation in diet.
