“…Third, the previously evidentiary attitude arose from early concerns over the applicability of extinction risk criteria, generally, and IUCN Red List Categories and Criteria, specifically, to wide-ranging exploited marine fishes. 109,110 These early concerns have not been borne out. 111 Since then, a large body of empirical meta-analysis and simulation analyses demonstrated strong alignment between the fisheries status of species and the Red List status, including for chondrichthyans.…”

“…The need for management and conservation of exploited elasmobranchs is widely accepted (Dulvy et al., ), and the provisions CITES offers are a useful tool to encourage sustainable management for internationally traded species (Vincent, de Mitcheson, Fowler, & Lieberman, ). However, the merits of investing in the management and conservation of marine species, through the trade‐related Convention, and the effectiveness, costs, impacts and benefits of this approach are still widely debated (Challender, Harrop, & MacMillan, ; Christie, Oracion, & Eisma‐Osorio, ; Cochrane, ; Cochrane & Doulman, ; Foster, Wiswedel, & Vincent, ; Franckx, ; Guggisberg, ; Mace, O'Criodain, Rice, & Sant, ; Rice & Mace, ). This is partly because a large range of established instruments and mechanisms for fisheries management already exist (Caddy & Cochrane, ; Cochrane & Garcia, ; Gutiérrez, Hilborn, & Defeo, ; Marashi, ; Melnychuk, Peterson, Elliott, & Hilborn, ), and because many species of elasmobranchs are caught as bycatch and have significant value for the domestic market, which is not subject to CITES controls.…”

Examining the impact of CITES listing of sharks and rays in Southeast Asian fisheries

CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora) aims to ensure that international trade in specimens of wild animals and plants does not threaten their survival. However, measuring the effectiveness and impacts of these trade regulations for commercially exploited aquatic species remains challenging. This study highlights observed or documented changes in elasmobranch fisheries in eight Southeast Asian countries before and after the listing of sharks and rays in CITES’ Appendix II, and the influence of CITES across five pillars or sectors of a “fishery assessment framework” developed especially for this purpose. Fisheries experts reported change was most common in the “governance” (e.g., policy, regulation and compliance) and “fisher(y)” sectors (e.g., structure and effort) of the assessment framework. The smallest change was recorded in “markets” (e.g., structures and prices) and “sociocultural” sectors (e.g., consumption, livelihoods and community awareness). Overall, the study demonstrates a measurable, albeit small, mostly positive influence of CITES in five of eight countries, while noting predominantly negative influences across two, and ongoing challenges for all in maintaining legal trade of these CITES‐listed species. The study concludes by offering guidance on future needs: most notably, more effort for long‐term collection of fundamental fisher‐, stock‐ and market‐related data to inform adaptive management and facilitation of legal trade where it is shown to be sustainable. Furthermore, as many of the shark and ray species under CITES provisions are transboundary stocks, increased support for communication and cooperation among regional fishery stakeholders is an ongoing need.

Informing CITES Parties: Strengthening science‐based decision‐making when listing marine species

et al. 2019

View full text Add to dashboard Cite

International trade in vulnerable marine species is regulated once they are listed in CITES Appendices (the Convention on International Trade in Endangered Species of Wild Fauna and Flora). Parties to the Convention submit proposal(s) 150 days prior to the CITES Conference for voting on the inclusion of new species in Appendices I and II, making a case for why CITES listing criteria are met in each case. Before the vote, Parties receive advice from (a) the Food and Agriculture Organization of the United Nations, (b) the International Union for Conservation of Nature—TRAFFIC and (c) the CITES Secretariat, among others. This paper offers an expert review of listing processes, which are the subject of much debate in fishery and environment‐protection communities, looking at two specific cases: silky shark (Carcharhinus falciformis, Carcharhinidae) and bigeye thresher shark (Alopias superciliosus, Alopiidae). The reviewers determine that the evidence made available to voting Parties is substantial, but suffers from non‐standard presentation across assessments. The best available data are not always presented or described transparently in relation to CITES criteria. An extension of the assessment period, as well as the opportunity to refute evidence, has been suggested as ways to support more informed and effective decision‐making by CITES Parties, whose composition of delegations varies greatly in their experience of marine species management and trade. Experts welcomed a greater coherence of advice between fishery and non‐fishery sources in the long term, and proposed a range of suggested improvements for the delivery of information and advice to CITES Parties.
