Currently there are about 2,500 Chinese white dolphins living in the Pearl River basin, the mid-Macau basin and Hong Kong, the home of Chinese mammals.

However, experts say, the number of white dolphins has shown signs of a significant reduction in the past few years, due to increased travel by sea, pollution of water sources and loss of habitat.

'We hope to have the participation of the community of scientists to analyze the standard gene, while creating a stable environment for the number of rare and precious Chinese dolphins' , the founding chairman of the fish observation team. Chinese white pig, Ms. Judy Chen, said.

Data collected will be important evidence for the regional government to develop a strategy to preserve Chinese white dolphin.

In addition, the biological samples of these dolphins will be sent to AND bank to investigate the environmental impacts affecting mammals.

Chinese white dolphin is one of many Pacific humpback dolphins, the only species that is unique to the pink outer skin. They were on the list of 'nearly extinct' that need to be protected by the International Union for Conservation of Nature (IUCN).

According to the Hong Kong Dolphin Conservation Society, the number of dolphins in Hong Kong has dropped from 158 in 2003 to 75 in 2000.
