Dual-method survey of recreational fishing for guitarfishes in Southern and Southeastern Brazil

Abstract

We comprehensively assessed marine recreational fishing of threatened guitarfishes (Pseudobatos percellens, Pseudobatos horkelii, and Zapteryx brevirostris) in Southern and Southeastern regions of Brazil. A dual-method approach integrated social media reports and in-person interviews to explore practices, challenges, and conservation implications of recreational fishing for these species. Seasonal capture of guitarfishes required the promotion of catch-and-release, especially during gestational periods, and the development of best angling practices manuals and accessible identification guides. With a focus on land-based activities and engagement with fishers, our findings underscored the importance of collaboration among researchers, recreational fishers, and conservationists to map and monitor recreational capture and contribute to guitarfish research and conservation.
