Maximising potential impact of Marine Protected Area placement: an integrated socioeconomic perspective
Meira Mizrahi studied the socioeconomic factors that influence the effectiveness of Marine Protected Areas at national and local scales. She found that factors varied in their influence depending on Marine Protected Area location and scale. Conservation organisations are using the results of this study to support Marine Protected Area planning
Status of Southeast Asia's marine sharks and rays
In Southeast Asia elasmobranchs are particularly threatened. We synthesized knowledge from the peer-reviewed and gray literature on elasmobranchs in the region, including their fisheries, status, trade, biology, and management. Our assessment included x species of sharkes and y species of rays. We found that 59% of assessed species are threatened with extinction and 72.5% are in decline; rays were more threatened than sharks. Research and conservation is complicated by the socioeconomic contexts of the countries, geopolitical issues in the South China Sea, and the overcapacity and multispecies nature of fisheries that incidentally capture elasmobranchs. The general paucity of data, funds, personnel, and enforcement hinders management. Reduced capacity in the general fishery sector and marine protected areas of sufficient size (for elasmobranchs and local enforcement capabilities) are among recommendations to strengthen conservation
Market surveys and social media provide confirmation of the endangered giant freshwater whipray Urogymnus polylepis in Myanmar
The giant freshwater whipray Urogymnus polylepis is a threatened species that is vulnerable to riverine and coastal marine pressures. Despite its threatened status, the range of U. polylepis is still being determined. In this study, photographic evidence of U. polylepis in Myanmar was provided through market surveys (2017-2018) and social media (Sharks and Rays of Rakhine Facebook page, 2021). Urogymnus polylepis is exposed to fisheries and habitat degradation pressures in Myanmar; therefore, conservation management is likely needed to ensure populations persist into the future
