Diversidade da ictiofauna de poças de maré da praia do Cabo Branco, João Pessoa, Paraíba, Brasil

Abstract

A survey of the tidal pool fish community was carried out between february/1987 and january/1988, at Cabo Branco Beach, João Pessoa, Paraíba, Brazil. Specimens were collected monthly at low tide, using rotenone. A total of 3143 specimens was obtained. The most speciose families were Ophichthidae (14% of the total number of species), Mugilidae (11%) and Muraenidae (9%), and the most representative ones in number of individuais were Gobiidae (48%), Pomacentridae (13%) and Labrisomidae (10%). The main resident species were Bathygobius soporator (Valenciennes, 1837) and Abudefduf saxalilis (Linnaeus, 1758). The presence of a large number of juveniles in the pools indicated the importance of the studied sites as nursery áreas for several fish species.
