At least five cetaceans died over the Chinese New Year weekend, including four finless porpoises and a rare Chinese white dolphin.
The bodies were sent to the Ocean Park Conservation Foundation (OPCF) for further investigation and were found to have multiple fractures.
Among the five cetaceans was a 2.5-metre adult Chinese white dolphin found stranded at Mo To Chau, a group of islands to the north of Lantau, between Chek Lap Kok and Tuen Mun.
The dolphin showed signs of choking, bone fractures and serious bone dislocation, while one of four finless porpoises was almost cut in half.
Samuel Hung Ka-yiu, founder and chairman of the Hong Kong Dolphin Conservation Society said that high-speed boats have always been a big threat to dolphins and that some of the aquatic mammals might be hit by propellers and chopped into pieces without being discovered, according to a report from The Standard.
Chinese white dolphins can be found in the waters around Lantau Island, where the habitat is influenced by the Pearl River freshwater outflow, while finless porpoises are usually found in southern waters including South Lantau from December through May.
