Aspectos da biologia reprodutiva de fêmeas de Etropus longimanus Norman, 1933 (Bothidae) da região de Cabo Frio, Rio de Janeiro: 1. tamanho da primeira maturação, tipo e época de desova

Abstract: Durante o período de novembro de 1986 a outubro de 1988 foram realizados estudos sobre a ictiofauna demersal na região de ocorrência do fenômeno da ressurgência em Cabo Frio, pelo Instituto de Estudos do Mar Almirante Paulo Moreira (IEAPM). A partir de coletas mensais da ictiofauna, efetuadas com arrasto de porta, e da água, para a obtenção dos valores da temperatura, constatou-se a abundância de Etropus longimanus na região. Foram obtidas 653 fêmeas, em diferentes tamanhos e fases de desenvolvimento gonadal, … Show more

“…In this present study near Cape Frio, juveniles of two species of Etropus were collected. Saad and Fagundes-Netto (1992) observed for E. longimanus females of the same region evidence of spawning at depths of less than 60 m, although they did not detect a specific location for the reproduction of this species. Although the Etropus larvae found do not have characteristics that allow their identification to species level, it is likely that the larvae present in the oceanic zone, specially where the shelf is wider, are E. longimanus that were transported there and then taken to a more coastal zone through oceanographic processes.…”
