Comparison between by-catch and shrimp production landings by the small shrimp trawlers in Perequê beach, São Paulo State, Brazil

Abstract

During 1987 and 1988, 44 samples of sea-bob shrimp (Xiphopenaeus kroyeri Heller, 1862) fishery by-catch, captured by small boats that landed in the Perequê beach, Guarujá, São Paulo state, Brazil, were analyzed. It was compared the average quarter of year production of each zoological group (including the trash too), and the total by-catch production with the sea-bob shrimp production. It was observed that, in the fourth, second and third quarters of year, the by-catch dominant group was the fishes, and in the first quarter was the crustacean group. The sea-bob shrimp production was not bigger than the by-catch production only in the first quarter of year.
