Abstract

This work presents an Adaptive Fisheries Monitoring Model that was evaluated by the method of clustering fishery data collected in 2016-2017 in the Araguaia-Tocantins basin. Data were obtained from the Integrated Fish Statistics System (SIEPE), which generated categorical and numerical variables. The analysis reveals the most significant numerical variables in the study were the fishing yield and engine power of the watercraft, while the most expressive categorical variables were popular species name and fishing environment. These variables should be taken into account in fisheries monitoring programs in the Araguaia-Tocantins basin, as well as the use of SIEPE to support fisheries management at different scales.
