To promote concern and increase awareness of the unfortunate circumstances of whales and dolphins, the HKDCS has been involved in various fields including carrying out research, offering related education to school children, providing volunteers a chance to join as research interns, and organising forums for dolphin-lovers which also serves as a social gathering for like-minded individuals.

Research projects include: The main targets of HKDCS's monitoring work are the Chinese white dolphins (Sousa chinensis), and the finless porpoises (Neophocaena phocaenoides).

At least 1,400 Chinese white dolphins are said to be living in this region, with about 300 alone in Hong Kong waters; but their population, temporal and spatial distribution, their use of habitat places and ranging patterns have not yet been studied adequately.

As a result of the discovery, the Chinese white dolphin is now placed at the highest level of protection under Taiwan's Wildlife Conservation Law.

The long-term aims of the exploratory surveys are to estimate the population of the Chinese white dolphin in the PRE and to study the spatial and temporal patterns of their distribution and habitats.

Data concerning their trends in abundance, distribution, habitat use, social organisation, life history, mortality rates and causes of Chinese white dolphins are to be acquired.

The HKDCS also holds an internship programme for local tertiary students, who are majoring in general biology, environmental science and/or other relevant fields, during the summer and also all year round.

Student interns will be able to help in a variety of research aspects; including the observation of impacts on Chinese white dolphins brought about by dolphin-watching activities, conducting boat surveys as well as studying about vessel effects on finless porpoises.

The HKDCS organises a wide range of activities that can be categorised into the following two groups: The HKDCS financed the "Environmental & Conservation Fund" and "Environmental Campaign Committee", and worked hand-in-hand with the Parent-Teacher Associations of participating schools, resulting in the latest creation of workshops for primary school students which will be held from September 2006 to December 2007.

The large scale exhibition "Get close with Chinese White Dolphin", was jointly held by the HKDCS and the Cityplaza.
