Diagnóstico ambiental da pesca de peixe na barragem de Corumana - Moamba

Abstract

This research aims to analyze the negative impacts of fish fishing in the Corumana – Moamba Dam. The research was based on a qualitative and quantitative approach. Non-probabilistic convenience sampling was applied to 30 fishermen; non-probability snowball sampling to 15 fish dealers at Corumana Dam, and non-probability sampling by intentionality directed to the representative of the fisheries administration sector at Corumana Dam. For data collection, semi-structured interview techniques, systematic observation and document analysis were adopted. Regarding data analysis, it was based on content and statistical analysis. According to the results obtained in the field, the Gillnet is the main fishing gear in the Corumana Dam with 40cm size gills established locally. However, it was found in this place that fishermen do not comply with this criterion due to lack of fish, a situation that also affects fishermen, over there that accidental capture. On the other hand, the use of a network with smaller mesh sizes than those established locally was observed in the Dam. Thus, these actions generate negative impacts, depletion of fish is identified as having the greatest negative environmental impact, the reduction of profits as a negative economic impact, and unemployment as a negative social impact. Following this, fishermen are recommended to adopt locally authorized meshes; and the fisheries administration sector at the Dam to hire Environmental Educators to implement environmental programs on site and reinforce the supervision of fishing gear and sizes of fish caught.
