The Chinese white dolphin injured in Hong Kong waters in January (2015) was caught last Friday (6th of February) after 18 days of search efforts and sent to Ocean Park for treatment.
The animal, nicknamed ‘Hope’ , was found off Shek Pik, on southern Lantau Island, by experts from Ocean Park (amusement park) and the Agriculture, Fisheries and Conservation Department who had been searching for the dolphin since January 20.
The team captured it using a specially adapted net and a sedative to slow the dolphin down. The preliminary health assessment found multiple serious wounds with three exposed vertebrae in front of its tail. Also the caudal (tail) vertebrae in front of its fluke was cut through and Hope suffered at least 4 deep transversal wounds on its tail stock, extending back from its dorsal fin toward the tail.
Over the next few days Hope will have 24-hour care and undergo a thorough examination – including X-rays, ultrasound, bacterial swabs and blood tests – and receive medical treatment at the hands of experts from the park, the conservation department and the Society for the Prevention of Cruelty to Animals.
The dolphin is a male, 2.3 metres long and weighs 135 kg. It was first spotted by a group of University of Hong Kong students off the Lantau village of Tai O on January 16. They saw severe cuts on its fin and back, probably caused by the propeller of an outboard motor.
Some marine conservation specialists argued that it should be left to recover in the wild. Images of the wounded animal were circulated on the internet, causing widespread concern and pressure that probably led to the current capture.
Chinese white dolphins are a protected species in the city, with only 60 of them living in Hong Kong waters.
Hong Kong Dolphin Conservation Society chairman Dr Samuel Hung Ka-yiu, who inspected the dolphin after its rescue, said there was no immediate threat to its survival, but judging from its condition it faced a long road to recovery.
Yesterday’s success was the sixth attempt to capture the animal. The society provided a boat for the search team to use in the operation, and sent its own team to observe the process. Asked whether the rescue procedure had caused any further injury to the dolphin, Hung said his society had shot a video of the rescue process for the park to release and it was better to leave that judgment to the public.

HK Marine Life’s Opinion:
It is questionable whether the dolphin can recover from such severe injuries. Only the veterinarian and experts can judge that. But the public should know that Ocean Park for many years ran a so-called captive breeding program for dolphins that in reality managed to kill 10 times more dolphins than were born. In fact the survivorship of healthy dolphins in captivity is preety poor. A study published in 1994 examined survivorship of dolphins and whales at Ocean Park (article online here), and showed that Ocean park was not unique – all captive dolphins and whales have relatively poor survivorship.
The dolphins injuries look extremely severe. A severed or partially severed vertebrae in front of the fluke would deprive it of proper locomotion and condemn it to early death. Now if the dolphin were to die as a direct or indirect result of these injuries, the humane question to ask would be how and where should it die? In the wild where it grew up where its social contacts are? Or alone in a clinical tank at Ocean Park.
Dr Hung has been very cautious in his statements. Part of the reason may be his well-founded opposition to Ocean Park’s dolphin facilities which serve to foster public appetite for dolphin shows and captive dolphins (see SCMP articel here).
