Regarded as relevant nursery areas for fishes, the estuarine systems shelter many commercially important species. From October 2008 to November 2009, we investigated the ichthyofaunal composition and described the routine of artisanal fishing with camboa net in the estuary at the Cassurubá Extractive Reserve, Bahia, Brazil. Samplings were conducted in three rivers, during the new and full moons. A total of 1,074 fishes were caught in 17 fisheries with nets, belonging to 26 species and 17 families, with a total biomass of 378.4 kg. The Gerreidae and Centropomidae families were the most abundant ones, and there was a predominance of catches. Out of the total, 50% of individuals which were at the first gonadal maturation (L50) described in the literature had a size less than the expected one, indicating growth overfishing. We recommends the establishment of management systems shared between the actors involved in this fishing art and the Cassurubá Extractive Reserve managers, in order to reduce the capture of individuals below the first gonadal maturation size.
Considerados relevantes áreas de berçário para peixes, os sistemas estuarinos abrigam muitas espécies comercialmente importantes. De outubro de 2008 a novembro de 2009 foi investigada a composição ictiofaunística e descrita a rotina da pesca artesanal com rede de camboa no estuário da Reserva Extrativista (RESEX) do Cassurubá, Bahia. As amostragens foram realizadas em três rios, nas luas nova e cheia. Um total de 1.074 peixes foi capturado em 17 despescas, pertencentes a 26 espécies e 17 famílias, com biomassa total de 378,4 kg. As famílias Gerreidae e Centropomidae foram as mais abundantes, dominando as capturas. Do total, 50% dos indivíduos que se encontram na primeira maturação gonadal (L50) descrita na literatura apresentaram tamanho inferior ao esperado, indicando sobrepesca de crescimento. Recomenda-se o estabelecimento de sistemas de gestão compartilhada entre os atores envolvidos com essa arte de pesca e os gestores da Resex do Cassurubá, com o objetivo de reduzir a captura de indivíduos abaixo do tamanho de primeira maturação gonadal.
