The Chinese Academy of Sciences (CAS) is the most prestigious professional science organization in China with China's scientific elite being members. It directs many research institutes, research programs, graduate training programs, and gives influential advice. The Chinese Academy of Engineering (CAE) gives important advice but unlike the CAS does not have research institutes of its own. The Chinese Academy of Social Sciences (CASS) has a similar role to CAS for social sciences and philosophy. There are also many more narrow academies such as the Chinese Academy of Fishery Sciences.
