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)
A sub-adult male finless porpoise measuring 1.43 m in length was found stranded at South Channel, Tap Mun last Sunday (17th August 2014). Tap Mun (also known as Grass Island) is in the northeast New Territories close to the Hoi Ha Wan marine park. According to marine police it was found entangled in fishing nets. The presence of net entanglement, CT scan images by Ocean Park Conservation Fund and the necropsy indicate that the porpoise as a result of net entanglement and likely drowned. Vets also found multiple abscesses I. Both left and right lungs suggesting chronic pneumonia. The porpoise also had lesions and bruising that suggest struggling in a net.
Finless porpoises (Neophocaena phocaenoides) along with the Chinese White dolphins (Sousa chinensis) are the only two cetaceans resident all year round in Hong Kong waters. This is the 34th cetacean stranding in 2014. Entanglement in fishing nets is the top cause of cetacean strandings in Hong Kong.
