Avaliação de tipos de iscas e fatores ambientais na pesca esportiva: um estudo de caso no estuário do Rio Potengi

Abstract

Sport fishing is an amateur fishing modality widely practiced in the Potengi River estuary and can be done on or off the boat, presenting a great wealth of species of interest in sport fishing. In our work, we focus on factors such as types of bait and environmental variables such as tidal amplitude, which can influence the activity. The analysis and treatment of data in the R software, using the GAMLSS model, showed that environmental factors such as tidal amplitude and tidal state are directly related to a greater amount of action and action-capture of fish that occur in the estuary. As well as the factors depth, amplitude and tidal state showed a statistically significant relationship with the variables action, action-capture and capture. Some groups of fish captured seem to be related only to a few points, while others are common to the three points analyzed in the estuary.
