CITES voted yesterday (4th October) on proposals to list silky sharks, all
three species of thresher sharks and all nine species of mobula rays on
Appendix II. Really great news !!

are all aware that sharks play an integral role in marine ecosystems and that
many sharks have life-history characteristics that make them intrinsically
susceptible to overfishing, international trade and at great risk for
population depletion due to insufficient controls on exploitation. Many of us have personally seen the decrease of shark populations over the years during the dives we have done all around the world.

of today, 18 shark and ray species are listed on Appendix I and II of the CITES. It took
until 2003 to protect the first two shark species : whale sharks and basking
sharks (appendix II); the great white followed in 2005 (appendix II); in 2013
hammerhead, dusky, oceanic whitetip sharks and manta rays were added (always appendix

Today, finally, this status was recognized by CITES even for silky sharks, thresher sharks and mobula rays, listed on Appendix II.
This list does not prohibit trade, but rather should ensures trade is
controlled in order to avoid use incompatible with the species’ survival.
That means that these species are not yet considered threatened
with extinction, but they may become so unless trade is closely controlled.

Proposal #42 added silky sharks while proposal #43 moved all three species of
thresher sharks
to Appendix II.

and thresher sharks have shown declines of between 70 and 80% throughout their worldwide
ranges, with local declines of more than 90%.

sharks are listed as “near threatened” while all three species of thresher
sharks species are listed as “vulnerable” on the IUCN Red List.

sharks are the species most commonly caught as a bycatch (fish caught
accidentally when targeting other species) in longline and purse seine
fisheries. There is targeted fishing for silkies as well, both for meat and for
the shark fin trade.

proposal drew strong support, with Mexico,
Chile, Bahrain, the DRC, Jamaica,
Ethiopia, New Zealand and Argentina speaking in support of
the proposal. Opposition came from Qatar, Japan, Nicaragua, Iceland
and Indonesia,
who believe sharks are best managed by regional fishery organizations rather
than global regulations. Surprisingly, also the FAO -an organization concerned
primarily with global food availability rather than the conservation of species-
spoke against CITES' listing for silky sharks, preferring regional control of
the species. Despite this opposition, the CITES membership won the match and silky
sharks entered the Appendix II.

dramatic and beautiful thresher sharks, with their long caudal fin, are highly
prized in the shark fin trade, and are believed to be at the highest risk of
extinction of all pelagic sharks. Annual takes of thresher sharks are difficult
to determine, as many animals move secretly into the fin trade, but it is
believed that well over one million thresher sharks may be harvested annually.

generally mature late (female between 12 and 14 years) and only give birth to
about two pups. Due to a lifespan of about 20 years and a 12 month gestation
period, they will only produce about 10 pups during their life cycle.

for and against the thresher shark listing followed a similar pattern to the
silky proposal, with opposition voiced by Iceland,
and the FAO. But the CITES membership voted with a large majority to list
thresher sharks on Appendix II.

Mobula (devil) rays are heavily commercially fished for their gill plates, which are used
in Asian medicine, and the global trade in dried gill plates is reported to be
more than 120 tons per year. Mobula rays have a very low reproductive rate,
bearing a single pup every 2-3 years, and therefore have limited ability to
recover from population declines. Proposal #44 placed all nine species of mobula rays on Appendix II. By secret ballot,
as requested by Japan, and
despite opposition of the repetitive Iceland,
Japan and Myanmar  -but surprisingly not the FAO-  the CITES membership voted positively and all species of mobula ray entered Appendix II.

these submissions started their iter in 2015, when Sri
Lanka, the Maldives
and Fiji
submitted the proposals, which were put forth in response to scientific evidence
of global declines in these species. More than 50 countries have agreed to
co-sponsor, listing one or more of these species, including several African
