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

Diversity of the tidal pool ichthyofauna of Cabo Branco beach, João Pessoa, Paraíba, Brazil

Resumo

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.
