Avaliação dos impactos do uso da arte de pesca chicocota na pescaria artesanal

Abstract

Chicocota is a cone-shaped net about 15 to 17 meters long, composed of buoys, weights, ropes, cuttings and a bag covered by raffia or mosquito netting, and is generally fixed in places with currents of water to catch the fish . At present, one of the challenges of the fisheries sector at national level is the conservation and sustainable use of fisheries resources; one of the measures taken by the Government of Mozambique to ensure the rational and sustainable use of fishing resources has been the fight against the use of destructive gear in fishing and the creation of closed and closed periods. The present study aimed to describe the capture of chicocota in the estuaries of the Bons Sinais, in Zambézia province, and to discuss the impacts of the use of chicocota on fisheries. The results show that the captures of chicocota art are mainly composed of Sergestidae and Penaeus monodon. The distribution of the length classes of these groups, which was influenced by the 2 mm mesh of the mosquito net used in the art, indicates that the use of the same, contributes to the decrease of the stock of these species in the adult phase, taking into account that the study constitutes nurseries for the species that compose the most captured families.
