Typology of the lagoons of northern Greece according to their environmental characteristics and fisheries production

The typology of the lagoon ecosystems according to their environmental characteristics and their fishery production can describe not only the dynamics of their fisheries capability but also the effectiveness of the applied fishery management. Lagoon systems are places with a great biological and ecological importance. Fishery is the main economical activity in these ecosystems but intensive agriculture, industry and tourism have degraded their sensitive environmental structure. According to their ecological characteristics, the human fishery interferences and their fishery productivity, twenty-three lagoon ecosystems are examined and classified in this study, aiming to the adaptation of a more suitable extensive aquaculture management for each group of lagoons. The application of new contemporary aquaculture management models can lead to the up gradation of their fisheries productivity in common with the conservation of their natural resources, as fishing is the best suited activity for these ecosystems, well adapted from the past.
