Fish bycath from shrimp fishery (Xyphopenaeus kroyeri) in the Bay of Santos, SP, (Brazil): I - quantitative studies

Abstract

During the sea-bob shrimp fishery, a large quantity of miscellaneous fishes are caught, of which the most part was discarded in the sea. In this paper, quantitative aspects of this bycatch products are analized, e.g. diversity of ichthyofauna, catch per unit effort and proportions of the sea-bob shrimp versus acompanying fish fauna. Sampling has been made from Sept. 1981 to Sept. 1983 at Santos bay, one of the most important fishing area from Brazil. A total of 5583 fishes were collected during 28 fishery operations with otter-trawl.
