The Concept, Content and System of Genetic Resources Meta database on China Marine Economically Valuable (Cultivated) Animals Study on the protection and conservation of marine biological genetic resources has gained much widely with the development of marine aquaculture in China. The more and more data have been collected but how to share these data demands attention too. Sharing of nature resources and biodiversity information useful for aquaculture and related research is the key to their sustainable utilization. Meta data refers to information on the location, source, content, or other specifies in relation to actual data. Meta database is a database designed and developed for meta data conservation and management, which provides services for the management, query and use of actual data. This system has powerful information query functions, such as query by institute catalogue, query by the matic information category, query by name, and query by author. It is rich in information. There are some meta databases such as China Information Network for Sustainable Development and other links on the Internet. But there is no mechanism for marine economically valuable (cultivated) animal genetic resources information exchanging and sharing in China at present. It is there for neccessary and urgent to setup an information query channel with meta data to help people know where to find required information on marine cultivated species and how to use them. This paper clarifies the definition, role and meaning of meta data, and outlined the concept, key elements and standards of meta database. The general status of biodiversity meta database in our country is also reviewed. We discussed the contents and strategies to setup the China Marine Economically Valuable (Cultivated) animal genetic resources meta database in the present paper, including standing criterion institute on collecting, processing, meta database constituting and sharing of information sharing of scientific data on genetic resources, and data collection framework designing. The conceptical basis on how to organize and construct this kind of database is presented.
