Would CITES listing help threatened sea cucumbers due to overexploitation?

August 14, 2019

Published on Mongabay on 10.08.2019 https://news.mongabay.com/2019/08/sri-lanka-pushes-for-protection-of-sea-cucumbers-amid-overexploitation/

  • With fewer species of sea cucumbers being recorded in catches, Sri Lanka stands to benefit from a proposal that is calling for increased protection of threatened species under CITES Appendix II.
  • Experts say there’s good precedent for believing that the listing will raise awareness and spur action to protect the sea cucumbers, citing the example of various shark species that received greater attention after being listed.

In the early 1980s, a common sight along the still unpolluted beaches of southern Sri Lanka was that of fisherfolk sun-drying small, blackish, cylindrical objects. They called them sea slugs, sea leeches, or sea cucumbers. These marine invertebrates were so abundant in the shallow coastal regions that they could be picked by hand during low tide.

But growing demand for sea cucumbers, considered a delicacy across Asia, has since driven the largely export-oriented Sri Lankan fishery to unsustainable levels.

After the sea cucumbers in shallow coastal waters were harvested, the populations in deeper areas were targeted by snorkeling fishermen and skin divers. The fishing pressure was so enormous that the sea cucumber fishery in southern Sri Lanka collapsed within a few years.

The eastern coast of the island suffered the same fate, and today the sea cucumber fishery is confined to the northern arc of Sri Lanka. Experts say they fear the remaining sea cucumber populations there, too, will be depleted if not managed properly.

“As mostly scuba divers hand pick sea cucumbers now, the pressure particularly on high value species are high. Some of these high value sea cucumber species are already rare to not available on many sites,” Chamari Dissanayake, from the University of Sri Jayewardenepura, told Mongabay.

Dissanayake was a former research officer at the National Aquatic Resources Research and Development Agency (NARA) who studied the sea cucumber fishery. She identified 24 sea cucumber species in Sri Lankan waters, of which 20 have some sort of commercial value.

But the number being caught and sold is fast shrinking. A study published in May this year in the journal Aquatic Living Resources records nine sea cucumber species in commercial catches from November 2015 to January 2017 in Sri Lanka. That’s down from 11 species recorded in a study carried out in 2012, prompting researchers to conclude that some species are already overfished. These include the high-value Holothuria fuscogilva, known as the white teatfish and listed as vulnerable in the IUCN Red List.

Teatfish are generally in high demand, and overfishing has caused the populations to decline in many countries. H. nobilis, the black teatfish, is another rare species found in the Sri Lankan waters and listed as endangered.

Weak species management systems, overexploitation by fishers, and vulnerable biological traits are the key reasons why teatfish sea cucumbers are under threat across their wide geographic range, said Steven Purcell, an expert on sea cucumbers at Australia’s Southern Cross University.

“The teatfish species of sea cucumbers are impacted by a compounding problem called ‘opportunistic exploitation,’” he told Mongabay. “This occurs when fishers over-harvest high-value species and then shift to harvesting lower-value species but can still collect the last of the high-value ones opportunistically, while they are out in the sea. This means that the high-value species, such as the teatfish types, can be harvested to the level of local extinction.”

As these teatfish require higher levels of protection against the international trade, a proposal has been submitted to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) to list H. fuscogilvaH. nobilis and the endangered H. whitmaei (not recorded in Sri Lankan waters) in CITES Appendix II.

The proposal, supported by the European Union, Kenya, Senegal, the Seychelles and the U.S., will be considered at the 18th Conference of Parties (CoP18) to CITES in Geneva from Aug. 17 to 28.

There are three appendices under CITES offering varying degrees of protection for species. Inclusion in Appendix II will require countries to justify, through data collection and research, that exploitation and trade of the teatfish species in question won’t jeopardize their populations in the wild.

For Sri Lanka, that could mean investing in field surveys to determine current population densities of black and white teatfish at multiple sites around the country, and socioeconomic surveys to determine which species, and how many, are collected by fishers, as well as identifying prevailing trading practices, Purcell said. This research would be required for assessing non-detriment findings and to inform decisions about whether trade should be allowed to continue at present levels.

Dissanayake’s research indicates that about 10,000 people depend on the sea cucumber fishery, a key earner of foreign currency.

“A solution has to be found by offering alternative livelihoods,” Dissanayake said.

Daniel Fernando, a co-founder of Blue Resources Trust, a marine research and conservation nonprofit, said there was good precedent to believe that achieving CITES listing for the overexploited sea cucumbers would be a key step toward protecting the species.

“Many people still consider marine fish just as a commodity and there is little focus on their protection,” he told Mongabay. “But CITES listing of marine species made lot of people around the globe to change this outlook.”

He pointed in particular to the listing of several shark species in various CITES appendices as helping to spur action for their protection.

“As a result of previous listing of sharks, many countries including Sri Lanka began investing in the protection of the species,” Fernando said. “All these marine species become threatened due to unsustainable fishing practices and lack of management.”

Spear-fishing threatens Giant Coral Fish

January 25, 2017

Images showing large Hump-head Wrasse (which is about 4.5ft) speared at Unawatuna raised concerns again whether spearfishing has to be banned. The Hump-head Wrasse  is categorized as ‘Endangered’ and it is important to protect this fish. Here is my article published on SundayTimes on 03.03.2013 http://www.sundaytimes.lk/130303/news/spear-fishing-threatens-giant-coral-fish-35194.html

Large Hump-head Wrasse speared last week

Large Hump-head Wrasse speared last week

Kalpitiya’s unsustainable fishing practices came under the spotlight recently after dozens of dolphins were killed after being trapped in banned fishing nets. Besides the charismatic dolphin, other “endangered” marine creatures are falling victim to illegal fishing methods, including spear fishing. Spear fishing could wipe out the world’s biggest reef fish, the Hump-head Wrasse, from Kalpitiya and other marine areas, warn marine biologists.

The Hump-head Wrasse is also known as Napoleon Wrasse, and is scientifically categorised as Cheilinus undulates. The male can grow up to six feet (two metres) and can weigh up to 190 kilograms. It has a prominent bulge on its forehead, hence the name “hump head.” Some females have a sex change and turn into males with maturity. The Hump-head Wrasse can live up to 30 years, but many get killed even before reaching maturity.

Kalpitiya fisherman Chanaka says divers who dive for chank and sea cucumber also target the Hump-head Wrasse. “Most of the larger Hump-head Wrasse are gone from Kalpitiya,” Chanaka said. In a bid to survive, the giant fish sometimes hide in cavities in underwater caves, but this does not stop divers from shooting their spears into the cavities and killing the fish.

In times past, spear fishing was done with free diving, without scuba kits. The time a hunter can stay under water was limited, but now modern spear-fishing makes use of elastic powered spear-guns and slings, or compressed gas-powered spearguns to strike the fish with accuracy. The scuba gear allow the diver to stay underwater for long periods, and divers use the extra time to go for the larger fish.

Kalpitiya Bar Reef Sanctuary architect Arjan Rajasuriya confirmed that the Hump-head Wrasse is becoming a rarity in Kalpitiya. All the larger fish have been hunted, and the Hump Head Wrasse appears to be highly vulnerable to over-fishing, he said.

The absence of the Hump-head Wrasse could be bad for the health of the coral reef, says Mr. Rajasuriya. The Hump-head Wrasse feeds on hard-shelled prey such as mollusks, starfish, or crustaceans. This includes the coral-eating Crown-of-Thorn starfish. With the disappearance of the large fish, the Crown-of-thorn starfish population is increasing and putting the system out of balance. There was a Crown-of-thorn starfish outbreak at the Pigeon Island coral reef last year.

In 1996, the International Union for Conservation of Nature (IUCN) listed the Hump-head Wrasse as vulnerable. In the Red List of Threatened Species it was later upgraded to “endangered”. The fish is also targeted for the live restaurant fish trade, where fish are kept live in tanks for the customer to pick the fish he wants cooked for him. Samantha Gunasekara of Customs Biodiversity says this kind of trade is not found in Sri Lanka.

Marine biologist Nishan Perera said spearfishing is practised in other parts of the island as well. Not only the Hump-head Wrasse, but also Giant Groupers, Parrot Fish and most of the giant fish are being over-fished in our waters by spear fishing, he said. The Giant Grouper can grow up to three metres, but such big specimens are rare these days, Mr. Perera said.

Wallapatta agarwood the new illegal million-rupee racket

February 16, 2014

An attempt to smuggle out wallapatta agarwood worth Rs. 12 million was prevented by vigilant Customs officers last week.

The offender had 16.8kg of the substance concealed in his baggage, Samantha Gunasekara of the Customs Biodiversity Protection Unit said. It had been cleaned and considered to be grade 1 quality. The offender was at Bandaranaike International Airport to board a Bangalore-bound flight. Preliminary investigations revealed that he was only a carrier, and investigations are underway to find the source of the agarwood.

Agarwood is a product of the wild tree, wallapatta, and it is illegal to own or take out a forest product without permission but because of its high value criminals collect and export it illegally. Wallapatta is scientifically classified as a sub-canopy tree growing in wet zone forests as well as in home gardens in these areas. The tree creates a resin called agarwood in its core as a reaction to a fungal infection, and this is used as a base for perfumes.

Perfumes produced using agarwood are expensive because of the resin’s scarcity, so a wave of illegal felling of wallapatta has been reported, several dozen cases from different parts of Sri Lanka in the first weeks of 2014.

In the latest case, Morontuduwa police arrested three men for cutting down a wallapatta tree and transporting in a van. Because the agarwood has to be exported illegally, stringent measures have to be put in place to nab the offenders who mastermind this racket.

Only some wallapatta trees affected by fungi manufacture the agarwood resin. Since there is no way to detect whether a wallapatta tree is secreting agarwood, trees are being felled indiscriminately for quick profits. Prof. Nimal Gunatilleke, who has studied the growth of wallapatta, warns that extensive removal of large mature trees could affect the survival of wild wallapatta trees, already categorised as “vulnerable” to extinction on the National RedList.

Prof. Gunatilleke points out that investigation of the tree’s reproductive ecology and low-cost propagation methods of wallapatta were needed to restore the growth of the tree in the forest and to increase domestic growth to reduce pressure on this rapidly dwindling natural resource. The Director General of the Department of Wildlife Conservation (DWC) said regulations to protect wallapatta have been drafted. He said the cultivation of wallapatta would be encouraged under stringent monitoring conditions.

Lanka won’t reveal shark secret

March 17, 2013

Malaka Rodrigo �reporting �from Bangkok – Sri Lanka maintained total silence on how it voted as an important proposal to protect sharks and manta ray species was passed earlier this week at the 16th Conference of the Parties (COP16) of Convention on International Trade of Endangered Species of Wild Fauna & Flora (CITES) in Bangkok.

Activists canvassing for the shark vote at the Bangkok conference

The proposal was passed with a clear majority after some tense proceedings as countries opposing the decision could canvass support from other countries and call for a re-vote. As expected Japan backed by India and Gambia challenged the decision on oceanic white-tip shark while China and Grenada had attempted to reopen the debate on the listing of the three hammerhead sharks. However, there was no revote in spite of attempts to reopen the debate.

It was widely speculated that China and Japan would pressurise Sri Lanka to vote their way but, Sri Lanka’s delegation head and Wildlife Conservation (DWC) Director General H.D. Ratnayake declined to comment on Sri Lanka’s position on the basis that it was a secret ballot.Following the favourable vote these species have been listed under Appendix-II of CITES and accordingly these species of sharks and manta rays will have to be traded with CITES permits following proof that they were harvested sustainably and legally.

Mr. Ratnayake said his department would work closely with the Fisheries Department and NARA to protect these species in Sri Lankan waters. He said this was just the beginning in an area where much more had to be done to protect Sri Lanka’s marine species. The Sunday Times last week reported on the importance of Sri Lanka voting in favour of the proposal to list oceanic white-tip shark, three species of hammerhead sharks and two species of manta ray. These are threatened species in Sri Lanka’s waters because of a big export market for their dried fins and gill plates.

Blood ivory a topic at International Forum on Wildlife Crime

March 17, 2013

Suspect traffickers arrested, stock seized in Lanka vital as probe continues� Malaka Rodrigo reporting from Bangkok

The poaching of elephants for tusks was another issue discussed at the many side events held parallel to the 16th Conference of Parties (COP16) at the Convention of International Trade on Endangered Species of Wild Fauna and Flora (CITES).

The 16th Conference of Parties (COP16) in progress

The fate of the haul of ivory seized recently by Sri Lankan Customs was a hot topic at CITES and the Asian Development Bank side event ‘Symposium on Combating Wildlife Crime’. The senior representatives of Sri Lanka participating at the event said the ivory will not be distributed to the temples.

Kenya Wildlife Service (KWS representative Halke Elme confirmed Kenya has received a letter from Sri Lanka saying the ivory will not be released. KWS is the state agency of Kenya protecting its wildlife and based on the recent reports that the ivory is to be released, KWS has sent a letter querying Sri Lanka. Mr.Elme said KWS received the reply from the Sri Lanka Government a few days ago.

The representative from the Lusaka Agreement Task Force who was present at the CITES-ADB symposium praised Sri Lanka for the seizure of the ivory. Lusaka Agreement Task Force is a law enforcement institution which is also the Secretariat of the Lusaka Agreement on Cooperative Enforcement Operations Directed at Illegal Trade in Wild Fauna and Flora. The representative said its officials had arrested suspects believed to be linked to the haul of ivory seized in Sri Lanka and added it is vital that the stock be kept as a criminal investigation is still ongoing.

Talking exclusively to the Sunday Times, CITES Secretary General John Scanlon said the convention also recognizes the role of transit countries to curb wildlife crime adding it is difficult to set up general rules for all the transit countries as the situation differs from one country to another. He said the CITES secretariat is aware of the seizure of the haul of the ivory by Sri Lanka Customs and subsequent attempt to release it to temples. Many of the Customs officers and other law enforcement officers present at the symposium shared the challenges they faced and their success stories at the CITES-ADB symposium on Wildlife Crime. It was also mentioned that over 1000 law enforcement officers were killed in trying to protect wildlife during the past decade.

Many of them were killed in Africa by well-armed elephant and rhino poachers, so it was not just the animal population that suffered, but also humans.
The level of interest seen in CITES about the haul of the ivory seized in Sri Lanka along showed that internationally Sri Lanka would get a black mark if we release the ivory for some other purpose. Sri Lanka Custom’s Samantha Gunasekera confirmed the stock of ivory is still in the Customs’ stores.
Thai Buddhist leaders prayed for poached elephants and called for the end to ivory use.

Symposium on Combating Wildlife Crime – Day3

March 17, 2013

“We need better intelligence and international corporation to curb Wildlife Crime” said the law enforcement officers participating the CITES-ADB Symposium on Combating Wildlife Crime. Being the last day, the participants were teamed into different groups for Breakout sessions on selected themes.  There were 3 Tracks on Technical Training on Special Investigative Techniques, Interactive Discussions on Wildlife Law, Policy and Governance, including barriers to Convictions and Interactive Discussions on Curbing Demand for Illegal Wildlife – Making Consumers Aware, Care.

Today is also special for me, since I had been a panelist of a session on “Multi-media, Social Media and Technology: Innovating for Wildlife”. I’ve started the session talking on importance of Social media in campaigning for wildlife also higlighting that Social media is yet to make a true penetration to some of the segments of public and experts in our part of the world. I’ve also shared the challenges I face on reporting Wildlife Crime. I was bit nervous to talk among giants in the field such as Brian Christy of NationalGeographic, but many has come to me after the panel, to having chat on different aspects I highlighted. I take this as an indication that I managed to deliver my first international talk successfully 🙂

Symposium on Combating Wildlife Crime – Day2

March 16, 2013

The second day of the “Symposium on Combating Wildlife Crime” as a side event to CITES COP16 was started at Queen Sirikit Convention Centre at Bangkok on 11.03.2013. The law enforcement officers and other involved parties in addressing Wildlife Crime have shared their experiences and discussed on ‘how to tackle the ever increasing issue of Wildlife Crime’. Everyone agreed that the penalties for Wildlife Crime is not as severe in comparison with similar crimes such as Narcotics, Gold or Human Trafficking; so that criminals take Wildlife Crime as ‘Low Risk’, but ‘Highly Profitable’ act.

The days topics discussed included Curbing the Demand for Illegal Wildlife and Wildlife Products, Wildlife Crime, Anti-Corruption, Integrity and the Rule of Law, National Policy and Legal Environmental Frameworks, Innovative Wildlife Enforcement Tools and Strategies. The day’s tasks were ended with a Parallel Break-out Sessions of Professional Peer Groups.

Lanka urged to vote for sharks, manta rays

March 10, 2013

As the triennial meeting of the Convention on International Trade in Endangered Species of Wild Fauna and Flora takes place in Bangkok, Malaka Rodrigo stresses on the need to save those species which are fast becoming a rarity in our waters

A crucial proposal on protecting sharks and manta ray species has stirred debates and discussions ahead of a vote at the ongoing Bangkok conference on the Convention on International Trade of Endangered Species of Wild Fauna and Flora (CITES). �The Sunday Times learns the proposal would be put for a vote by secret ballot among CITES signatory nations at the conference where the Sri Lankan delegation is led by Wildlife Department Director General H.D. Ratnayake.

Sharks waiting to be auctioned

Attempts to contact Mr. Ratnayake to know how Sri Lanka would vote were not successful. �CITES is often hailed by scholars and conservationists as the most effective international environmental agreement to date. Sri Lanka was one of the 178 signatory countries that meet once in three years to discuss measures to protect wildlife species threatened by trade-driven over-exploitation.

The convention and its appendices list species that could be at risk and call for the control of import, export and re-export of such species through a permit system.

They also state that species that are already threatened with extinction cannot be commercially traded. �More than 30,000 such species are given trade protection through CITES and 70 new proposals have been presented at the conference — the 16th meeting of the Conference of the Parties (CoP 16).

Aquatic species top the conference agenda with proposals calling for the protection of shark and manta ray species among other threatened species. This species to be protected include oceanic white-tip shark, and three species of hammerhead shark and two species of manta ray — species found in Sri Lankan waters.

The hammerhead shark is notable for its unusual shape of the head which has given it its English name. Locally, it is known as “Udalu Mora”. There are three species of hammerhead sharks — scalloped hammerhead (sphyrna lewini), great hammerhead (sphyrna mokarran) and smooth hammerhead (sphyrna zygaena). The scalloped and great hammerhead sharks have already been listed as ‘endangered’ while smooth hammerhead sharks are considered ‘vulnerable’ to extinction, according to IUCN Red List.
Oceanic white-tip sharks (carcharhinus longimanus), said to be an aggressive species, live in deep waters, but fishermen have become more accustomed to kill them and as a result they are ‘vulnerable’ to extinction. Sharks and mantas live long and take time to mature sexually. Sharks and mantas have a long gestation period and produce only a few young.

Small bony fish, which have many predators, usually lay thousands of eggs during one spawning season for the survival of the species. Sharks, top predators themselves, give birth to a few young during their life time as they face no major threats. But the situation is different today and they too face a major threat with the humans invading the ocean and engaging in a killing frenzy.

But sadly, overfishing, driven by the high demand for shark fins and manta ray gill, does not allow the shark and manta populations to recover. Shark fin soup is a popular delicacy in China and other East Asian countries while manta gill plates are used in Chinese medicine. Hundreds of sharks are caught daily in Sri Lankan waters and there is a big export market for their dried fins.

If the CITES proposal is adopted, Sri Lanka will be required to introduce a permit system to regulate the export of shark and manta products. Welcoming the proposal, Dr. Hiran Jayawardane, former Chairman of the National Aquatic Resources Research and Development Agency (NARA), said large manta ray species were a rare sight today in our waters and it was indeed good to see efforts being made for their protection. “Not just hammerheads, but all shark species are under threat today due to large-scale fishing.”

Dr. Jayewardene said many countries such as the Maldives and Seychelles had taken measures to protect their marine resources which in turn benefitted them economically through tourism and other areas. �“We need a more enlightened and sophisticated approach to marine conservation,” Dr. Jayewardene said drawing attention to the upcoming Marine Conservation Forum organised by the Colombo-based Indian Ocean Marine Affairs Co-operation (IOMAC). The Forum will focus on international experience and inspire countries like Sri Lanka to be more compassionate towards marine life.

Fisheries Department Director General Nimal Hettiarachchie said the department was planning to start a monitoring programme on shark landings. He pointed out that Sri Lanka had already banned the catching of Thresher Shark, a species threatened with extinction.

Conservationists said if the catching continues in an unsustainable manner, sharks and manta rays would decline to a point that the entire trade will collapse. “So it is better to act now before it is too late. Let’s hope that Sri Lanka will take the right decision in joining hands with the rest of the world in protecting fish in the troubled waters,” one conservationist said.

CITES conference to adopt measures to combat overfishing, illegal logging and wildlife crime

March 3, 2013

The 16th Conference of Parties (COP16) of CITES starts today. This meeting will be particularly important for Sri Lanka as there are few proposal for enlisting Manta Ray (Maduwa in Sinhala) and Sharks in CITES Appendix II which will then need a permit system, if the country needs to export parts of these animals. The Gill Rakers of Manta Ray and Fins of the Sharks are on demand which made Sri Lanka one of the top Manta Ray gill rakers exporting country.

In addition there was a decision to release the 359 African Elephant tusks that has been seized by customs. CITES has banned trading of Elephant Ivory, so it is also not appropriate to encourage releasing ivory to the system and many calls to destroy the stock publicly. Hence, the CITES’ COP16 will be relevant to Sri Lanka in many angles and to follow up the proceedings, please follow Window-to-Nature..!!

CITES came into action in 1973 also completes 40 years in 2013. Here is an extract from CITES COP16 Media Kit..

The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) will hold its next triennial conference in Bangkok from 3 to 14 March to decide how to improve the world’s wildlife trade regime that has been in place for 40 years. Some 2,000 delegates representing 178 governments, indigenous peoples, non-governmental organizations and businesses are expected to attend and discuss, among other things, 70 proposals for amending the rules for specific species. Many of these proposals reflect growing international concern about the escalation of poaching and illegal trafficking of wild animals, the destruction of the world’s marine and forest resources through overfishing and excessive logging and the risks that wildlife crime represents for the security of the planet.

The 70 proposals submitted by 55 countries from across all regions of the world seek to improve the conservation and sustainable use of marine species (including several shark species) and timber species (including over a 100 species from Madagascar), the vicuña population of Ecuador, freshwater turtles, frogs, crocodiles, ornamental and medicinal plants and many other animals and plants. Proposals addressing elephants, white rhinoceros, and polar bears were also submitted.

This year, the 70 proposals1 will be divided up as follows:
– Animals: 48 proposals
– Plants: 22 proposals
– Transfer from Appendix I to Appendix II: 10 proposals
– Transfer from Appendix II to Appendix I: 12 proposals
– Inclusion into Appendix I: none
– Inclusion into Appendix II: 25
– Deletion from Appendix I: 7 􀃆 from which 6 exctinct animal species
– Deletion from Appendix II: 11 􀃆 from which 4 extinct animal species
– Annotations to the Appendices: 5

February 25, 2013

Overfishing threatens the magnificent and prized ‘Ali Maduwa’, writes Malaka Rodrigo�

A giant “maduwa”, or manta ray, was netted last week by fisherman in Welipatanwila, Ambalanthota, on the South coast. The ocean creature was pregnant and weighed 1,500 kilograms. A week earlier, another manta ray was caught by fishermen in Akkaraipattu, on the East coast. Both sea creatures have been identified as Giant Oceanic Manta Rays, the largest member of the ray family.

The Giant Oceanic Manta Ray was a common catch a decade ago, but the creature is steadily becoming less common. Known locally as “Ali Maduwa”, the creature is hunted primarily for its gill plates, which are extracted, dried and exported. Dried gill plates are widely used in Chinese traditional medicine. A kilogram can fetch between Rs.15,000 and Rs. 20,000. The manta ray uses its cartilaginous gill plates to filter the plankton that it lives on. The delicate gill filaments also play a role in the manta ray’s breathing system.

Manta rays are slow breeders with long lives. The animal, which can live to 50 years (some are known to have lived to 100 years), has a gestation period of more than a year and gives birth to just one single pup. Young mantas take between 10 and 15 years to reach sexual maturity.

“Manta ray populations simply cannot survive the current level of commercial fishing,” says manta expert Daniel Fernando. “Any target fishing that annually removes even a relatively small percentage of the breeding adults results in a rapid decline in overall populations within a few years. The remaining mature rays cannot breed fast enough to replace those lost to fishing. Manta rays in our waters are already in decline. Fishermen say they rarely catch large mantas in our waters any more.”

Daniel Fernando works for the Sri Lanka Manta Project (Manta Trust) and collects manta ray landings data for his research. �Most of the time mantas are a bycatch of gill nets, says Dr. Rekha Maldeniya, a marine fish expert who works for the National Aquatic Research and Development Agency (NARA). “Our fishermen do not like it when these large creatures get entangled in their nets, because they can damage the net.”

The manta ray comprises only 1 per cent of large pelagic fish catch, such as tuna, Dr. Maldeniya says. “NARA identifies the importance of skates and rays, but we don’t have the funds to carry out comprehensive research on these sea animals.”

Daniel Fernando of Manta Trust says fishermen can release manta rays that get entangled in their nets, but do not because they know the commercial value of the manta’s gill plates. He says the manta would be spared if fishermen used other sustainable methods of fishing, such as the pole-and-line tuna fishing method practised in the Maldives. The gill-net is one of the least sustainable of fishing methods, he adds.

Sri Lanka, like most countries, has not reported manta ray landings to world bodies such as the United Nations Food and Agriculture Organization (FAO). Researchers believe Sri Lanka is among the leading countries that fish manta rays, and the closely related Devil Ray. There is hope on the horizon for the rays if the Convention on International Trade in Endangered Species (CITES) makes a global decision on manta exploitation.

Ecuador, Colombia, and Brazil have proposed that the two manta ray species be listed under CITES, an international treaty drawn up in 1973 to prevent international trade from threatening animals and plants in the wild. Proposals to list manta rays and scores of other species in the CITES list will be discussed in March at the 16th Conference of Parties (COP16) to CITES. CITES has 177 member countries, including Sri Lanka. A two-thirds majority vote is required for the adoption of listing proposals. If this is agreed, Sri Lanka will have to introduce a permit system for the export of manta ray gills, a step that would help monitor and manage this particular fishery.

Manta expert Daniel Fernando said the move was directed at international trade and would not affect Sri Lankans fishing for local consumption. The move would help manage manta ray populations. Alternatives, such as manta ray tourism, as practised in the Maldives, would bring long-term benefits.�Mr. Fernando said a workshop on manta rays was held in Colombo for CITES delegates. It was attended by major countries in the region, including India, Bangladesh, Bhutan, Nepal, Indonesia, and the Maldives. All participants were positive about regulating the manta ray fishery.

In 2011, Shark Advocates International president Sonja Fordham met senior Sri Lankan officials to discuss shark and manta ray conservation.

Ms. Fordham was a leading figure in bringing the Giant Manta Ray under the Convention of Migratory Species (CMS). Through this listing, Sri Lanka and all CMS parties with giant mantas in their waters have agreed to protect the species and cooperate in preserving manta habitats.

Sonja Fordham says equal efforts should be extended to protect the oceanic whitetip sharks and three species of hammerhead, all of which are found and fished off Sri Lanka.

“We are hopeful Sri Lanka will participate in the CITES meeting and support the listing of these vulnerable shark and ray species,” Sonja Fordham told the Sunday Times.

“Support from Sri Lanka would send a positive signal about the country’s commitment to sustainable exploitation of marine resources and can help secure a much-needed global safeguard, before it’s too late.”
