The support and the further development of the aquaculture branch require proper management. For this reason information concerning biological, environmental and socio-economic data is needed. AQUABANK, a database with information concerning the state of development of the Greek aquaculture is operational since March 1994. The main data base, located in Iraklion, is available on-line. Also a microcomputer based system exists containing summary information. The information system is based on Client/Server technology. The initial data were collected from 75 farms (covering almost 60 per cent of the total national production being of all different types: vertical integrated, on-growing, big or small). The further data collection has taken place on a regular base from 10 selected farms according to their geographical distribution and type. The available information includes environmental parameters (T, O2, etc.), and also data about the biological performance of the reared population (growth rate according to the season, pathological problems, rearing technologies, etc.). AQUABANK, in relation with other databases containing socio-economic data (production statistics, legislation aspects, etc.), constitutes an important tool for aquaculture management.
