A brand new research led by scientists from Florida Worldwide College (FIU) and the Wildlife Conservation Society (WCS) has discovered that there was substantial progress in implementing protections for chondrichthytes (cartilaginous fish together with sharks, rays and chimaeras) underneath the Conference on Worldwide Commerce in Endangered Species of Wild Fauna and Flora (CITES).
Whereas that is excellent news within the general combat for shark and ray conservation, the research additionally identifies areas in want of enchancment to safeguard probably the most threatened species.
The brand new research, revealed in Marine Coverage, finds that 48 per cent of the 183 CITES signatories have applied regulatory reforms, starting from full prohibition on the taking and commerce of sharks and rays to species-specific protections and science-based catch quotas.
Among the many protections in most want of enforcement are these surrounding manta rays and mobulas, that are hunted for his or her gill-rakers regardless of having been listed on CITES Appendix II (species which may be threatened with extinction if protecting measures usually are not enforced) in 2016.
Gill-rakers – the tissue in between the rays’ gills which is used to filter plankton from the water – are notably wanted by the Chinese language market, the place they’re dried and powdered to be used in a ‘conventional’ remedy.
Indonesia was singled out by the report as a nation the place the implementation of CITES Appendix II listings has been successful on this regard.
The nation’s manta populations have lengthy been a first-rate goal of the gill-raker commerce, however prevention and enforcement of CITES measures have resulted in a decreased catch and commerce of the rays.
Along with the unlawful commerce in shark fins and manta ray gill-rakers, chondrichthytes (cartilaginous fish together with sharks species are additionally focused for his or her meat, oil-rich livers and skins, with shark species making up nearly all of merchandise.
In accordance with information collected since 2014, 47 per cent of all contraband seized by customs officers had been shark fins and, general, shark merchandise had been virtually 4 occasions as more likely to be seized as merchandise comprised of rays.

Most protected species
Sharks and rays are among the many most threatened animals within the oceans – roughly one-third of pelagic shark and ray species are listed as ‘Critically Endangered’, ‘Endangered’, and ‘Susceptible to Extinction’ on the IUCN Crimson Checklist of Threatened Species.
Of the animals mostly afforded protections by way of CITES, whale sharks (Rhincodon typus) are prime of the record, with 53 nations implementing measures to forestall commerce within the species.
All species of sawfish (household Pristidae) are afforded globally vital protections, with oceanic whitetip sharks (Carcharhinus longimanus), nice white sharks (Carcharodon carcharias), and basking sharks (Cetorhinus maximus) rounding out the highest 5 most protected species.
In mild of the persevering with threats to those species, the oceanic whitetip shark, whale shark and all mobulid rays are to be thought-about for even larger protections with an inventory on CITES Appendix I (species underneath direct risk of extinction) on the subsequent CITES assembly in November 2025.
Whereas the research reveals {that a} prohibition within the commerce of endangered species is having a marked impact on shark and ray conservation, it additionally reveals a large implementation hole in how CITES laws are enforced.
Indonesia, one of many largest exporters of shark merchandise, is singled out for reward as a consequence of its sturdy investments in species identification instruments and regulatory frameworks, and the aforementioned success in stemming the unlawful commerce in manta ray merchandise.
Different nations, such because the Dominican Republic, Samoa, Monaco, and Colombia have all applied protections for sharks during the last decade, and the Maldives has prolonged the total safety already afforded to sharks to incorporate rays.
On the other facet of the fence, the report’s authors observe that market surveys in Hong Kong and China counsel commerce in CITES-listed sharks stays much like the quantity previous to their itemizing.
Mexico and Sri Lanka are named as main sources for the unlawful commerce in shark fins, indicating they’ve issues imposing the implementation of laws, regardless of having formal CITES commitments in place.
To be able to deal with the shortcomings of imposing present laws, the report identifies numerous essential steps that should be taken, together with scaling up species identification instruments at ports, rising coaching for customs officers, bettering information assortment on commerce volumes and sources, and fostering cross-border collaboration amongst fisheries and wildlife businesses.
‘This research reveals the highly effective influence CITES listings can must drive higher nationwide degree conservation motion,’ stated the research’s lead writer, Dr Mark Bond of FIU’s Institute of the Setting.
‘Nevertheless, there’s way more to be performed and CITES shark and ray listings will solely stop extinctions if nations take accountability and prioritise improved fisheries administration laws, compliance, and enforcement, in live performance with sturdy monitoring, and deal with the gaps recognized on this research.
‘Sharks and rays don’t respect political boundaries so international efforts and regional cooperation on the scale that CITES can ship is essential to their survival.’
