Another dead shark was found in Hong Kong waters over the weekend, just days after a dead dolphin and shark washed up on two separate Tuen Mun beaches.
It is believed that the two sharks are of the same, or related, shark species.
At 5:45pm on Saturday, a swimmer told lifeguards at Butterfly Beach about what he thought was a shark carcass floating near the shore.
Around six or seven lifeguards then went into the water, finding and retrieving a dead 36-centimetre-long spadenose shark.
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 60cm-long Pacific Spadenose shark (Scoliodon macrorhynchos) washed ashore at Butterfly Beach in Tuen Mun at about 11.30am this morning. As always when a shark or suspected shark is spotted at beach in Hong Kong,
the warning flag was hoisted and beach-goers are told not to swim there, while marine police and the government flying service scour the area for sharks. No more Sharks were found. The shark may have been still alive when it washed ashore, but is now being autopsied by Ocean Park Conservation Fund.
All of Hong Kongs gazetted beaches are enclosed with shark-prevention barriers of steel wire mesh. The shark nets for the beach were inspected but no damage was detected. It is possible that the shark came ashore during high tide – or it was simply small enough to slip through the mesh.
A similar or possibly the same species was found at a beach on Lamma in August 2014.
Also on Thursday, the carcass of a male Chinese white dolphin (Sousa chinensis) was found on a beach in Sham Tsang in Ts uen Wan district. An AFCD spokeswoman said the department was alerted to the discovery at 11am. The dolphin measured 2.1 metres long and was also sent to Ocean Park for an autopsy.
