High overexploitation risk due to management shortfall in highly traded requiem sharks

Most of the international trade in fins (and likely meat too) is derived from requiem sharks (family Carcharhinidae), yet only two 56 species currently regulated. Here, we quantify catch, trade, and shortfall national regional fisheries management (M-Risk) for all shark based on 831 assessments across 30 countries four Regional Fisheries Management Organizations (RFMOs). Requiem comprise over half (60%) annual reported global Chondrichthyan catch with most (86%) identified fin trade. are inadequately managed by fisheries, an average M-Risk (50%) ideal score, consequently 70% threatened globally. The high volume these iconic require worldwide sustainable supported full implementation CITES regulations this newly listed family.
