      Abstract

      In this study we report information on post-release mortality in artisanal fisheries of the Angular Angelshark Squatina guggenheim Marini, 1936, a critically endangered shark in Southeastern-South Brazil. We analyze artisanal fishing operations, which take place on the beachfront and verified that despite the release of all 74 captured sharks, about 30% were found stranded, debilitated or dead, a few minutes later, due to the release method (throwing). We suggest adjustments based on successful field integration experiences with fishers.
