INFORMATION MODEL FOR SUSTAINABILITY ANALYSIS OF FISH RESOURCES IN GREECE

摘要

Fishery activities in Greece have a strong impact on the structure of the ecosystems and the patterns of sustainability offish resources. The presented information model consists of a multidimensional database on sea fishery in Greece and data mining software for sustainability analysis offish resources. The 2241 time series data for the period 1990-2007 are stored in database and concerns quantity offish catch by areas, species, months, kind of fishery and fishing tools as well as value and employment. The developed system of data mining rules applies the computing of descriptive statistics and trend models. The database analysis shows sustainability for total fish catch in the time period 2000-2007, but some significant changes of the fish catch by areas and by species. The attained information has 2 aspects: (1) ecological, regarding needed measures to control water quality and minimise pollutions of coastal areas; (2) economical, related to effective management of sea fish resources in Greece. An analysis of the mined information, for the present and the future, can support experts and researchers in the fields of biology and ecology to study changes in sea fish communities, in biodiversity and in marine ecosystems as a whole.
