Thousands of turtles captured in Madagascar despite ban

12.11.2010
New research has revealed up to 16,000 endangered turtles are being caught each year by villagers in just one region of Madagascar, despite a government ban.

Researchers from the University of Exeter and Blue Ventures Conservation say the figure, thought to be a conservative estimate, is the first direct assessment of turtle exploitation on the island.

The study highlights the extent of small-scale fishing, traditionally very difficult to monitor, and could be vital in finding a way to sustainably manage turtle fishing in the region.

Dr Annette Broderick, from the Centre for Ecology and Conservation (Cornwall) at the University of Exeter, said: "We conducted this study because we know this small-scale, artisanal fishing is going on despite it being illegal to catch turtles under Malagasy law.

"Because turtles are an endangered species, it's important for us to know what's going on in the region so we can work with the local community to find a sustainable way forward."

Traditionally it has been very difficult and expensive to get data on small-scale, artisanal turtle catch because of the difficulty of access to these remote areas.

This research used a new approach, involving locals in the process by paying a village representative to document each turtle caught, including taking a picture of each one.

Frances Humber, who works for Blue Ventures Conservation, said: "Catching turtles for their meat is an important part of Malagasy culture for many coastal people, but the villagers also understand the importance of ensuring the future of this resource.

"This study is a great way of involving communities in the process of finding a sustainable way forward. Obviously we can't be sure every turtle catch is reported, so we view the figures from this study as a conservative estimate which is still nevertheless very valuable for informing policy."

The research monitored the harvest of marine turtles at 12 coastal villages in Madagascar and documented a total of 699 marine turtle landings, including four species – with the majority being green turtles.

Combining these data with those from previous studies in the region produced a conservative estimate of annual turtle catch in the south-western province of Madagascar of between 10,000 and 16,000.

Frances Humber admits the figures from this study are a cause for concern, but insists Madagascar should not be singled out.

"We'd expect similar harvests in many countries in the tropical coastal developing world, so this isn't an isolated issue, but clearly it is a cause for concern when dealing with endangered species," she said. "It's possible the model for this study could be used elsewhere to get a better idea of numbers.

"Until we get more details, it's difficult to draw conclusions about what is sustainable and how we can find solutions. Clearly making turtle fishing illegal hasn't worked, so we need to work with communities to promote sustainable practices."

The research is due to be published in Animal Conservation.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
