Information model for sustainability analysis of fish resources in Greece

Abstract

Fishery activities in Greece have a strong impact on the structure of the ecosystems and the patterns of sustainability of fish resources. The presented information model consists of a multi-dimensional database on sea fishery in Greece and data mining software for sustainability analysis of fish resources. The developed system of data mining rules applies the computing of de- scriptive 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.
