Avaliação do estado de exploração dos recursos pesqueiros acessíveis á pescaria artesanal de arrasto para praia, no distrito Mogíncual, província de Nampula, norte de Moçambique

Abstract

The high demand and the need to obtain fish resources increased considerably, leading to overexploitation [ CITATION Abd141 \l 2070 ]. The work entitled the assessment of the state of exploitation of fisheries resources accessible to artisanal beach trawling in Mogincual’s district, Nampula Province, North of Mozambique, was conducted based on the historical data of 2010 to 2017 provided by the Directorate of Studies, Planning and Infrastructures of the Ministry of Sea, inland waters and fisheries (MIMAIP) and by the National Fisheries Research - Delegation of Nampula, corresponding to the sampling of artisanal beach trawling fish in Mogincual’s district. The specifics objectives were to identify the main species of animals with the highest catches rates, to estimate the maximum sustainable yield and the maximum sustainable effort. The main species of animals with the highest catches rates were Rastrelliger kanagurta, Sardinella gibbosa, Decapterus kurroides, Decapterus macarellus, e Amblygaster sirm. It was verified statistics differences between the maximum sustainable yield for Schaefer 3702,9 t and Fox 3969 t and the maximum sustainable effort for Schaefer 61574,3 and Fox 54936,5, meaning that Fox’s model is going to result in higher yields than Schaefer’s model. The fisheries resources accessible to artisanal beach trawling in Mogincual’s district are in a situation of overfishing since the annual average catches are above the MSY, which shows the loosing of replenishment capacity of the removed biomass by fishing.
