Xinhua reported on the 22nd of July (2017) that a rare rough-toothed dolphin (Steno bredanensis), named Jiangjiang, was released back to sea earlier this week, two months after it beached itself and was rescued in Guangdong Province.
The 2.2-meter male dolphin was found stranded on the coast of Heisha Bay near the city of Jiangmen (200 km west of Hong Kong) on May 3. It was suffering breathing troubles, according to Yang Naicai, a vet who joined the rescue operation.
Rescuers checked the dolphin’s breathing, gave an injection of antibiotics, and provided food and medicine to help it regain its strength.
The animal was housed in a pool designated for dolphin rescue at the Pearl River Estuary Chinese White Dolphin National Nature Reserve.
“We maintained round the clock monitoring, hoping for a miracle,” said Chen Hailiang, from the reserve.
The dolphin, which weighs around 100 kg, was released back to the sea on Thursday as its physical condition had returned to normal.
Although the rough-toothed dolphin, a national second class protected species, can be found in deep tropical, subtropical and temperate waters around the world, it is a rare visitor to Chinese coastal waters.
In 2014, a rough-toothed dolphin stranded in Guangdong died despite rescue efforts.
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 dead dolphin was found by boatman at around midnight off Sai Wan Ho. The dolphin measured about 1.5 m in length. Police recovered the carcass and has passed it to the AFCD for further identification and post-mortem.
The dolphin recently spotted with terrible dorsal fin and back injuries likely caused by an outboard motor has been identified as an individual frequently spotted in Hong Kong waters off Lantau Island (see map below). The individual designated WL212 was identified by cross-referencing against a photographic database of dorsal fin markings. This allows us to make the before and after comparison of the injuries in the featured image courtesy of the HKDCS (HK Dolphin Conservation Society).
