Caracterização da pesca artesanal com base na monitoria realizada no Parque Nacional do Arquipélago do Bazaruto, Província de Inhambane

Abstract

The artisanal fishing sub-sector has been important for the development of the country's economy but also for the well-being of the coastal population, which depends on this activity as a safe source of protein and income generation. This study aimed to evaluate artisanal fishing based on monitoring carried out on Bazaruto Island. The internship was carried out over a period of 90 days, but the monitoring of artisanal fishing was carried out over 74 days in the fishing centers of Sitone-sede, Nhadave and Jenha, respectively. A total of 84 fishing boats were sampled, of which 41.67% were in the fishing center of Sitone-sede, 30.95% in Nhadave and 27.38% in Jenha. During the study, the activity of 91 fishing nets was recorded, of which 51.65% were in Sitone-sede, 27.47% in Nhadave and 20.88% in the Jenha fishing center, respectively. A total of 41 fish species were identified during the fishing monitoring: 31 species in the Sitone-sede fishing center, 29 species in Nhadave and 27 species in the Jenha fishing center. The most abundant species were Decapterus sp. and Sardinella sp. There was a high similarity in the specific composition of the catches between the fishing centers. The highest catch per unit of effort (CPUE) was observed in February with 180.86 kg/boat and the lowest CPUE in January with 48.13 kg/boat. The analysis of the size structure of the species Decapterus sp. and Sardinella sp. (which were most frequently caught in the fishing centers) shows that Decapterus sp. had a size variation between 12 cm and 25 cm (n= 65) while Sardinella Sp. had a size variation between 12.5 cm and 16 cm (n=25). These length ranges of these two species of pelagic fish are below their maximum lengths.(TRADUÇAO NOSSA)
