Biomassa dos principais recursos de peixe de Boa-Paz, Moçambique

Data collected during a survey conducted by the Soviet trawler Sebastopolsky rybak , in January 1987, covering the Boa-Paz area, Mozambique, were analysed. The biomass of demersal fish was found to be higher than the one of pelagic fish. The most representative group among the demersals was the first grade fish, where the families Sparidae, Lethrinidae, Lutjanidae and Serranidae were included, corresponding to a biomass of about 3,500 tonnes. In the pelagics the family Carangidae was the most important one and the species Decapterus russelli and Trachurus trachurus showed the highest biomass estimates in this family.
