“…Recreational fishing in these regions is growing in popularity (Martinazzo et al., 2022). The impact of recreational fishing on guitarfishes and other elasmobranchs has been inadequately investigated, thereby highlighting a need for further research (Gallagher et al., 2017).…”

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.

Abandoned, lost, or discarded fishing gears (ALDFG) are major pollutants in water ecosystems, however, there is a serious lack of estimates on the loss of recreational fishing gears worldwide. To fill this gap, some recreationists like magnet fishers, who use neodymium magnets to retrieve metal items from water, can provide additional information. As they often remove ALDFG, we aimed to carry out the first social media analysis of their online content by searching ALDFG in their posts. During our work, we analyzed Hungarian magnet fishers’ posts, covering a total of 6 years from their initial activities on social media. In total, 2,889 posts were scanned of which 1,039 photos and 84 videos were analyzed. Magnet fishers caught 2,018 fishing gears while a total of 31 types of fishing gear were identified. Significant differences were found between flowing (n = 1,959, mean ± SD = 12.89 ± 16.51) and standing waters (n = 889, mean ± SD = 24.69 ± 31.39) in the numbers of fishing gears. Based on the results, we can conclude that ALDFG is a common freshwater pollutant in the country, and social media activities of magnet fishers can be used in detecting freshwater ALDFG containing metal.
