Alimentação de Isopisthus parvipinnis (Teleostei: Sciaenidae) na Baía de Santos, São Paulo

Abstract: Stomach contents of 688 specimens of Isopisthus parvipinnis from Baía de Santos (SP) sampled between J une!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 … Show more

“…For the other species there is some information on food habits (Lowe-MacConnell, 1966;Braga et al, 1985;Rodrigues & Meira, 1988;Soares, 1989;Teixeira et al, 1992;Amaral et al, 1994), but none is available on diel changes.…”

“…Studies conducted in southern and south-eastern regions of the Brazilian coastline record a broader diet for this species, although only the Teleostei and Decapoda Natantia categories have been shown to be important (Soares, 1989;Soares & Vazzoler, 2001). For the coast of Ilhéus, I. parvipinnis is stenophagic according to definitions presented by Zavala-Camin (1996), and carnivorous, where at least juveniles tend to consume crustaceans.…”

“…Furthermore, they can contribute to the formulation of fishery management plans and policies in favor of a better utilization of the catches (Gulland, 1966). Research regarding biological aspects of I. parvipinnis has been conducted in the southern (Coelho et al, 1988;Chaves et al, 1998;Chaves et al, 2003) and south-eastern regions (Soares, 1989;Giannini & Paiva-Filho, 1994;Soares & Vazzoler, 2001) of Brazil, but there are no studies on this species in northeastern area. Especially in this region, the continental shelf is very close (about 32 km) (França, 1979), and because of this the low depth trawling is concentrated in few areas, possibly increasing the impacts.…”

“…Na presente investigação, as inferências são ainda mais restritivas em virtude (1) do reduzido número de exemplares analisados, (2) da ausência de um tratamento particular por estação do ano e faixa etária, e (3) da reunião das duas espécies de Citharichthys em um grupo único, exceto durante uma pequena parte do período. A circunstância número 2, por exemplo, cuja influência sobre a interpretação da dieta de uma espécie é bem exemplificada por Soares (1989) e Rodriguez (1996, pode ser a causa da diferença constatada entre os dados referentes ao conjunto de C. arenaceus e C. spilopterus e aqueles referentes a uma e a outra, individualmente.…”
