Sharks and rays high on CITES #CoP17 agenda | CITES

CITES regulates international trade in over 35,000 species of plants and animals, including their products and derivatives, ensuring their survival in the wild with benefits for the livelihoods of local people and the global environment. The CITES permit system seeks to ensure that international trade in listed species is sustainable, legal and traceable.

Press Release

Geneva 16 September 2016: South Africa, home to one quarter of the world’s 400+ shark species, will this month host the triennial meeting of the World Wildlife Conference where strengthened protection for sharks and rays will again be high on the agenda.

Delegates from over 180 countries attending the meeting – also known as CITES #CoP17 – will receive updates on actions taken following CoP16 in Bangkok, where five shark species, namely the oceanic white tip, porbeagle and three species of hammerhead, and all manta rays were given protection under CITES Appendix II, with trade in these species now being regulated to prevent over-exploitation.

At CITES #CoP17 Parties will be asked to consider three more proposals to bring sharks and rays under CITES trade controls, namely to include:

  • Silky shark Carcharhinus falciformis in Appendix II
  • Thresher sharks Alopias spp. in Appendix II
  • Devil rays Mobula spp. in Appendix II

Shark Fins & Meat Contain High Levels of Neurotoxins

shark meat fins neurotoxins

In a new study, University of Miami (UM) scientists found high concentrations of toxins linked to neurodegenerative diseases in the fins and muscles of 10 species of sharks. The research team suggests that restricting consumption of sharks can have positive health benefits for consumers and for shark conservation, since several of the sharks analyzed in the study are threatened with extinction due to overfishing.

The species sampled for this study were the:

  • Blacknose shark (Carharhinus acronotus)
  • Blacktip shark (Carcharhinus limbatus)
  • Bonnethead shark (Sphyrna tiburo)
  • Bull shark (Carcharhinus leucas)
  • Great Hammerhead shark (Sphyrna mokarran)
  • Lemon shark (Negaprion brevirostris)
  • Nurse shark (Ginglymostoma cirraum)
  • Atlantic Sharpnose shark (Rhizoprionodon terraenovae)
  • Smooth Hammerhead shark (Sphyrna zygaena)
  • Tiger shark (Galeocerdo cuvier)

The two toxins analyzed were Mercury and β-N-methylamino-L-alanine (BMAA) which have been linked in recent studies to both Alzheimer’s disease and ALS.

Shark Crimes: How DNA Helps Fight Fin Trade

Humans kill some 100 million sharks annually, largely for shark fin soup. Some shark species, like the oceanic whitetip, have declined up to 99 percent.

To find out how new trade restrictions are affecting the global shark fin trade, shark geneticist Demian Chapman is using DNA to get an accurate picture of how they’re caught and traded, as well as the role they play in our oceans.

“The same techniques that are used for solving crimes,” said Chapman, a Pew marine fellow, “are the exact same ones we use to solve crimes involving wildlife.”

Nassau Grouper: Bahamas National Tust PSA

Bahamas National Trust Fact Sheet: Nassau Grouper

Epinephelus striatus

The Nassau Grouper belongs to the Seabass family of fish. All Seabass have strong, stout bodies and large mouths. Five dark brown bands, a black saddle-like spot near the tail fin, and a dark streak running from its nose through its eye are features that distinguish the Nassau Grouper from other groupers. The dorsal fin is notched between for ward spines. The Nassau Grouper can change colour from pale to almost black to match its surroundings. It can grow to 1 to 2 feet long and can reach a maximum of 4 feet and weigh fifteen pounds or more. Nassau Groupers may live for more than 25 years. The Nassau Grouper is a valuable fisheries re source and an important part of the coral reef community. The grouper is usually found in caves, crevices and cracks of the reef. It is rarely found deeper than 90 feet. This fi sh often rests on the sea bottom, blending with its surroundings. Nassau groupers are found through out the Caribbean Sea.

Nassau Groupers, like most Seabass are predators. They sit camouflaged out side the openings of caves, and wait for unsuspecting prey to swim by. They see well without much light, and often hunt at dawn and dusk when other fi sh are looking for shelter or waking up. Groupers eat many animals such as lobster, crab, octopus and shrimp.

Groupers spawn around the full moon during late December or early January after the seawater has begun to cool. They gather around banks by the thousands to spawn. Around this time they change colour: black on top and white on its belly. Spawning takes place at sunset when males and females move from the shallows and into deep water. Here they rise quickly to the surface in small groups releasing eggs and milt into the open sea. Males are often seen nudging the bellies of females as both sexes swim rapidly toward the surface. Spawning continues for several days following the occurrence of the full moon. Nassau grouper eggs are clear, less than 1 millimetre in diameter and they are buoyant. After they are fertilized they are carried away from the reef by the wind and tide. Within 20 – 45 hours baby fish called larvae hatch from these tiny eggs. After a month at sea, the ocean currents return the larvae to the reef. Of the million or so eggs released by each female, less than 1% will live and grow into adults. Nassau Groupers can begin life as a female and then switch to male. Change can hap pen at any time after maturity – when they reach 10 to 24 inches long and 5 – 6 years old. Male groupers are larger and thus targeted by fishermen. This can result in a shortage of sperm. In response to heavy fi sh ing pressure resulting in limited sperm, it is possible that a female may change to a male before reproducing as a female. In some groupers, there is no sex change.

There is a strong local market for the Nassau Grouper. Traditional dishes such as Boiled fish and Grouper fingers, keep the Nassau Grouper in high demand. The fishing of Groupers provides hundreds of thousands of dollars in income to fishermen around The Bahamas.

Nassau grouper is eaten by barracudas, lizard fish, dolphins, sharks and other large predators of the reef community. But the predators that have the biggest impact on the grouper population are humans. People are fishing groupers before they can grow to maturity and reproduce. Sex change may also cause a problem. In undisturbed areas there are usually equal numbers of male and females. In heavily fished areas there are often three or more times more females than males. This means many eggs will not be fertilized during spawning. Other threats include, habitat destruction, coral breakage from divers, siltation from construction, runoff from logging and agriculture, dredging, sewage, oil spills and other contaminants that harm coral reefs where Nassau Groupers live.

There are a number of measures that can be taken to protect and manage the Nassau grouper:

  • Establish Marine parks and Reserves where the fi shing of grouper is prohibited.
  • Establish a minimum harvestable size limit and enforce the minimum legal size for a grouper which is 3 pounds.
  • Protect spawning aggregation sites – because of fishing at these sites, groupers are susceptible to overfishing.
  • Develop alternative fishing strategies: encourage fishermen to catch other species of fish.
  • Support the Closed Season for Grouper during the designated dates (December – February).

Sharks Play Critical Role in Ocean Food Web | Pew

As apex predators, tiger sharks and other shark species play a critical role in maintaining the health of ocean ecosystems.

But shark populations are decreasing around the world, due to overfishing and the high demand for shark fin soup. When their numbers plummet, it can have a chain reaction on ocean food webs, impacting seabirds and commercially important fish species, such as tuna and jacks. This is only one example of how removing sharks from the marine environment may have other negative effects that spread through the food web.

In July 2011, The Bahamas declared a shark sanctuary in its Exclusive Economic Zone. Two months earlier, scientists had tagged 12 oceanic whiteips around The Bahamas and created an animation that tracked the movement of three of those sharks. The scientists found that although they are highly migratory, oceanic whitetips spent most of their time within the sanctuary. Sanctuaries are an important refuge for sharks.
