Thailand releases endangered Leopard Sharks as part of conservation efforts

A young Indo-Pacific Leopard Shark glided into the waters of southern Thailand's Maiton island after a short countdown. This was the first attempt to "rewild" this endangered species.

The spotted shark, once a common sight among snorkelers and divers, has been declining in the wild due to habitat loss and overfishing over the last decade, even though they thrived in private tanks.

Why not release the successful breeding population from the aquariums back into nature so that the wild populations can recover? Metavee Chuangcharoendee is the project manager of the StAR Project Thailand. This partnership was launched last year by the government, aquariums, and NGOs.

In December, the newest release included the nearly two-year-old sharks Maiton Hope Spot Toty. The pups were among seven released to date, after having been bred and reared in an aquarium for a little over a year.

All were taught the behaviours that they would need to survive in the wild. This included a sea pen at Maiton Resort where 'they adjusted to natural conditions.

The sea pen was built to help acclimatise sharks to their new environment. Shark nannies take care of them - feeding them daily, monitoring their growth, and recording their health in general. This will allow them to stay healthy and prepare them for life on the open ocean, said Metavee.

Marine veterinarians performed final health checks on the pups two days before they were released to the sea in December.

Before the animals could be released, they were subjected to a series of tests, including ultrasounds, which assessed the internal health of the sharks, as well as the installation?of acoustic trackers, DNA samples, and measurements.

Metavee, who is a wildlife conservationist in Thailand, said that while the species of sharks are protected under Thailand's laws on wildlife conservation, they need to be better managed and given more protection.

Metavee's success does not just depend on the number of sharks it releases, but also the signs of a true recovery, such as frequent sightings of divers, proof of breeding in nature, and the absence from the fish market of leopard sharks.

"That is probably what I'd call a long term success," she said. (Reporting and writing by Napat Hasshasartar; editing by Himani Sarkar).
