Wildlife experts in south China are trying to rescue an endangered Chinese white dolphin (Sousa chinensis) that is in worsening health after swimming into a tributary of the Pearl river a week ago. The dolphin is approximately 30 years old and swam into the Baisha Rivernear Jiangmen in Guangdong Province on the 1st of February. It is now in a stretch of water about 100 km from the sea. “[…] the skin of the dolphin is festering and its health is deteriorating … its moving area is shrinking,” said Feng Kangkang, a worker with Jiangmen Chinese White Dolphin Nature Reserve, on Thursday. The team is watching the dolphin around-the-clock and recording its health condition, according to the Guangdong provincial ocean and fishery department. Dubbed the “giant pandas of the sea” by some, the Chinese white dolphins are mainly scattered in a few coastal areas where they exist in small numbers. About 2,000 are known from areas around the Pearl River, including HK which at the last count, was down to about 60 dolphins. (Photo/Xinhua)
The Agriculture, Fisheries and Conservation Department (AFCD) released 10 green turtles seized in an earlier enforcement action in the southern waters of Hong Kong on Monday (November 15).
The 10 green turtles are among the 35 green turtles and one hawksbill turtle seized from a fish raft in Sok Kwu Wan Fish Culture Zone on September 30. The turtles were assessed by vets at Ocean Park Hong Kong (OPHK) and have been looked after there with constant monitoring and veterinary care.
An AFCD spokesman said, “This is the largest batch sent to OPHK since it started helping to provide care for rescued sea turtles. The department is thankful to OPHK for making special arrangement to accommodate the sea turtles and the veterinarians and staff for taking care of them.”
The 10 green turtles weighed from 9.6 kilograms to 23kg and measured about 45 centimetres to 61cm in shell length. All of them were considered to be in good condition and ready to be returned to the sea. The AFCD will continue to work together with OPHK on the other turtles seized in the operation and release them in batches later according to their health condition and the weather.
Before the turtles were released to the sea, the AFCD tagged each of them with a microchip and Inconel tags for future identification. Satellite transmitters were also attached to the carapaces of some of the turtles. By tracking the movement and feeding grounds of green turtles in the sea, the AFCD can collect data for formulating appropriate conservation measures and share its findings with other conservation authorities for the better conservation of sea turtles.
Members of the public are urged to report any sighting of sea turtles to the department via 1823.
The Hong Kong Underwater Photo and Video Competition 2016, jointly organised by the Agriculture, Fisheries and Conservation Department (AFCD) and Hong Kong Underwater Association, announced its winning entries.
The Hong Kong Underwater Photo and Video Competition, in its 5th year now, received 443 entries this year, featuring marine ecology, habitats and marine life in Hong Kong waters.
An AFCD spokesman said, “Entries over the years have showcased the beauty of marine life and habitats in Hong Kong waters, and have helped promote the conservation of the marine environment.”
The event comprised a photo competition and a video competition. In the photo competition the categories were Macros/Close-ups and Standard/Wide Angle. In addition to prizes for champions and runners-up in each group, there were Special Prizes for Junior Underwater Photographers presented by the judging panel to encourage less experienced underwater photographers to participate in the competition.
I have added the winning video entries to this Youtube playlist. The winning photos as well as the video entries can also be found on the AFCD Chinese page for the competition and the competitions Facebook page.
On Friday (12/8/16) the Agriculture, Fisheries and Conservation Department (AFCD) released three juvenile green turtles in the southeastern waters of Hong Kong.
The green turtles were found by members of the public at Pak Lap Beach and Silverstrand Beach in Sai Kung and a refuse collection depot on Tin Hau Temple Street in North Point between January 2014 and July this year.
After an initial check-up by the AFCD, the turtles were taken to Ocean Park Hong Kong (OPHK) for a thorough veterinary assessment and necessary medical treatment. Since then, they have been looked after at OPHK.
The three green turtles weighed 8.6 kg to 34.5 kg and measured about 45 cm to 66 cm in shell length. All of the turtles were in good condition and ready to be returned to sea.
Before the turtles were released into the sea, the AFCD tagged each of them with a microchip and Inconel tags for future identification. Satellite transmitters were also attached to their shells. By tracking the oceanic movement and feeding grounds of green turtles, the AFCD can collect data for formulating appropriate conservation measures and share its findings with other conservation authorities for the better conservation of sea turtles.
The green turtle is a globally endangered species. Members of the public are urged to report any sighting of sea turtles to the department via the government hotline 1823 to help protect them.
A dead finless porpoise (Neophocaena phocaenoides) was found in Discovery Bay on Sunday afternoon, the fourth dead marine mammal discovered in four days after the bodies of three dolphins were discovered on Thursday.
It was found in the water and handed over to the Ocean Park Conservation Foundation for an autopsy. The OPCFHK said that the porpoise was a 1.55 metre long female and the body had reached the fourth stage of decomposition. Its cause of death has yet to be determined.
On Thursday, the bodies of three Chinese white dolphins (Sousa chinensis) were found – one entangled in fishing wire near Lido Beach in Sham Tseng, one in waters near Lamma Island and another in Fan Kwai Tong off Lantau Island.
The Hong Kong Dolphin Conservation Society (HKDCS) estimate that there has been a decline since 2014, when 61 dolphins were estimated to be in Hong Kong waters.
A locally-rare finless porpoise (Neophocaena phocaenoides) was found dead in the waters off Shek O, last week (19th November 2015).
The adult female finless porpoise was discovered on Wednesday at Tai Long Pai, bringing the total number of cetacean strandings this year up to 35. It measured 162 centimetres in length and was already severely decomposed. Dissection revealed a fishing rod in its stomach, but the cause of death is still unknown.
Marine Police received information that the corpse of a finless porpoise had been spotted floating near Shek O. The porpoise was then collected and brought to Marine Police Regional Headquarters at Sai Wan Ho, where Ocean Park Conservation Foundation’s Cetacean Stranding Response Team took on the cadaver for autopsy.
Elsewhere in China the Global Times reports another finless porpoise washed up dead in Poyang Lake in Jiangxi Province. Poyang Lake is a freshwater lake which along with the Dongting Lake is host to an estimated 500 finless porpoises. This stranding brings the total for Poyang Lake for 2015 to 5.
A wider restricted area in southern Lamma would keep out the noisy junk parties that threaten the nesting site of rare creatures
It’s a sunny September day and half a dozen junks and pleasure boats are anchored in a scenic inlet on southern Lamma Island.
House music is booming and banana boat-tugging speedboats zip across the bay, while those with the energy make the 50-metre swim to shore – unknowingly committing an illegal act by frolicking on the sandy shores of Sham Wan beach.
The beach is one of the few regular nesting sites for endangered green sea turtles in southern China and is a restricted area during the breeding season between June and October. It was designated a site of special scientific interest in 1999.
Illegal entry is liable to a maximum fine of HK$50,000, but that’s only if nature wardens are able to stop such violations.
Scientists and green groups want the Agriculture, Fisheries and Conservation Department to ramp up protection efforts by expanding the 0.5-hectare restricted zone to the entire bay to keep out junk parties.
A study by the Eco-Education and Resources Centre between 2013 and 2015 recorded anywhere between 12 and 17 boats anchored in the bay at weekends. Average noise levels went as high as 80 decibels, similar to a police siren, in some parts of the bay.
Green turtles are known for their migratory behaviour and loyalty to feeding sites and nesting grounds. Tracking efforts show they usually swim to Wanshan Archipelago, Fujian waters, the Pratas Islands, the Spratly Islands and the Philippines after visiting Hong Kong.
“Nesting sea turtles are easily affected by human activity,” said ERC science manager Dr Michelle Cheung Ma-shan.
“If a turtle is put off from approaching the beach, it will be forced to lay its eggs underwater, where they will die.”
There have already been notable drops over the years. Between 1998 and 2006, there were 14 records of nesting turtles in Sham Wan. But only two have been documented since 2006, with the last sighting in 2012.
Floating markers similar to ones used in marine parks could be set up to demarcate the entire bay as a protected area.
The ultimate goal is to establish a marine park in hopes that strengthened conservation efforts can bring back sea turtles in greater numbers, says Ken Ching See-ho, the ERC’s founder and director.
“The first step is to expand the restricted area under the Wild Animals Protection Ordinance.”
Cheung said nature wardens should be patrolling the beach to keep people out, but their field studies showed they were only present about “60 to 70 per cent of the time”.
Ching said the department could look to successful examples of turtle protection areas overseas, such as the Sandakan Turtle Island Park in Sabah, Malaysia, and a protected area in Taiwan’s Penghu Islands.
Green Power chief executive Dr Man Chi-sam said Hong Kong’s efforts at turtle conservation were “very behind” and “very passive”. “[The findings] also reflect the low public awareness and understanding of this species in Hong Kong,” he said.
A department spokesman said regular patrols were conducted in the area to control unauthorised entry and to monitor the nesting activities of green turtles. “We will step up patrols and put up more warning signs to alert the public not to enter during the restricted period.”
