The Agriculture, Fisheries and Conservation Department (AFCD) released two juvenile green turtles (Chelonia mydas) in the southeastern waters of Hong Kong yesterday (September 21).
The turtles were found by members of the public at the Ma Wan Public Pier and Victoria Harbour in September 2013 and July this year. After an initial check-up by the AFCD, the turtles were taken to Ocean Park Hong Kong (OPHK) for veterinary assessment and have since been looked after at OPHK.
They weighed 8.4 kilograms and 26kg and measured about 42 and 60 cm in shell length. Both were in good condition, indicating that they were ready to be returned to sea.
Before the release into the sea, the AFCD tagged them with a microchip and Inconel tags for future identification and attached satellite transmitters to their shells. Tracking their movements and feeding grounds provides the AFCD with valuable data to formulate appropriate conservation measures and it can then share its findings with other conservation authorities for better conservation of sea turtles.
Green sea turtles are a globally endangered species. Members of the public are urged to report any sighting of sea turtles to the department by calling 1823 to help protect them.
In Hong Kong, all sea turtle species are protected under the Wild Animals Protection Ordinance (Cap 170) and the Protection of Endangered Species of Animals and Plants Ordinance (Cap 586). Of the five sea turtle species found in Hong Kong waters, the green turtle is to date the only species known to nest locally.
The decomposing body of a whale shark, a rare species in local waters, was found off the coast of Cheung Chau. The five-metre creature was spotted about 50 metres off the island by Cheung Chau resident Dan Carew. He reported the sighting to the police shortly before 7pm yesterday (31st August 2015).
The marine police later located the decomposing body near a coastal area off Cheung Chau Peak Road West. Carew told the media he saw the shark floating off the sea at sunset and immediately left his home to check it. It was later washed closer to the coast. Carew said there was a nylon rope around its tail. After studying the pictures and a video provided by Carew, the Ocean Park Conservation Foundation said it was a whale shark, characterised by its square head and pectoral fins.
A spokeswoman said the foundation could not tell how it died and would try to learn more from the Agriculture, Fisheries and Conservation Department. He said the largest known extant fish species was rare in local waters, although there had been occasional sightings.
Skin, fat and muscle samples were collected but a necropsy could not be made because of the poor condition of the carcass and the environmental restrictions on- site. AFCD has arranged carcass disposal.
