In this study we tested the hypothesis that Centropomus parallelus Poey moves between areas where fishing tourism is important, but the management rules for recreational fisheries are different. Fieldwork was conducted from May 2014 to June 2017 in an estuary located in the border between the states of SAo Paulo and Parana, South-Southeastern Brazil. Through a mark and recapture experiment, 2.000 individuals were tagged, of which 42 were recaptured. Among these, six fish were recaptured in Parana, after being tagged in SAo Paulo, and a fish was recaptured in SAo Paulo, after being tagged in Parana. These results support the hypothesis tested and indicate an uneven use of C. parallelus by anglers in both states. Thus, the use of the species and the recreational fisheries regulations need to be reviewed in the study area, taking into account the ability of C. parallelus to move across political boundaries and the importance of a fish-oriented fisheries management regime.
