Estudo da pescaria de arrasto de praia em Angoche provincia da Nampula

Abstract

The present work took place from January to March 1998, in two fishing centers - Thamole and Kwirikwige, in the district of Angoche, in Nampula Province. The objective was to Study the Beach Drag Fishing. Samplings were taken daily with the exception of bad weather and/or important worship days. As for the specific composition, 124 species and 46 families were identified in the center of Thamole, and in Kwirikwige 115 species and 49 families. The dead tide in both centers was the one with the highest number of species in relation to the live one. Of the most abundant families, Carangidae was the most dominant, both in the two centers and in both types of tide. As for the dead and living tides, the species Stolephorus indicus returned to dominate in both, while in Kwirikwige the species Thryssa setrirostris and Insidiaíor secutor dominated in the tidal and viva respectively. The species Stolephorus indicus was the most abundant in Thamole and Kwirikwige Secuior insidiaíor. In relation to catches per unit of effort (CPUE), Kwirikwige was the center that always showed the highest yields. In full capture the trend was the same with Kwirikwige again outperforming thamole. As for the study of the population structure of the species: SardineUa albella, Thryssa vitrirostris and Stolephorus indicus, they presented lengths that varied from a minimum of 2.5 cm to a maximum of 18 cm. All of them showed significant differences between the two centers.
