Caracterização da ictiofauna acessível a pesca artesanal no estuário de Bons Sinais, distrito de Quelimane província da Zambézia

Abstract

The study of the characterization of the ichthyofauna was carried out from September 2017 to August 2018 and had as main objective to provide subsidies on the specific composition, population structure, diversity and abundance of the communities. Samples were collected at two fishing centers Chuabodembe and Icidua in the flood and ebb tide. 6702 individuals belonging to 24 families and 43 species were collected. The Carangidae family was the most abundant in terms of species numbers (8), and the Engraulidae and Clupeidae families with 3 species were the second most abundant. The Engraulidae family contributed the most with number of individuals and weight in both fishing centers. As for the specific diversity, the Chuabo Dembe fishing center was more diverse than Iciduaa. The results of the length structure showed that the species are most often captured in the juvenile state. However, the results obtained in this work show that the species captured in the estuary of Bons Sinais are of great economic importance, and that is why management rules must be established so that species do not exhaust.
