Quantificação e carcinofauna acompanhante do camarão-rosa Farfantepenaeus subtílis (Pérez Farfante, 1967) em pescarias industriais na plataforma continental Amazônica.

Abstract

On the north coast of Brazil, the pink shrimp (Farfantepenaeus subtilis Farfante Pérez, 1967) is exploited by the fishing industry, using fishing gear bottom trawl with doors, catching lots of fish. This work aims to contribute to the quantitative and qualitative knowledge of carcinofauna escort of pink shrimp fishing industry in the Amazon continental shelf. We estimated the escort carcinofauna capture period for the study 11,479,870 kilograms. The relationship between pounds of pink shrimp caught and escort carcinofauna very varied during the study period, whereas, the average ratio (pounds of pink shrimpxarcinofauna kg) was 1:1. The communities crab, shrimp and portunids were present in more than 97% of trawls were monitored and categorized as very common. The average CPUE's escort carcinofauna differed significantly between seasons, statistically significant differences between the ranges of depth, but not between time of day. We identified 44 species of crustaceans malacostracos, divided into five groups: shrimp (9), lobsters (4), crabs (20), portunids (7) and stomatopods (4). The specimens are deposited in the Collection of the Laboratory for Crustacean carcinological the Cepnor/ICMBio.
