In this research direction, the Institute’s activities include research in biology, ecology and spatiotemporal distribution of species, the assessment of the fish stocks status and the collection and organization of fisheries data.

Particular emphasis is given to addressing the problems of overfishing, due partly to the excessive and uneconomic development of the fishing fleet that has led to a decline in fish stocks, thereby reducing efficiency and increasing costs of fishing.

Many research activities have ecosystem orientation and include research on trophic networks,  the habitats of species, the impacts of climate change on the distribution and abundance of marine resources and the interactions between fishing and the marine ecosystem.

The Institute’s activities also cover the management of the coastal zone and focus on the study of the interactions between human activities that compete for space and resources (fisheries, tourism, services, agriculture, industry, aquaculture, urban development and transport) and their impacts on the coastal environment and the coastal ecosystems.

The activities of this research axis serve important aspects of fisheries policy and legislation and they are harmonized with the requirements of the Common European Fisheries Policy. The post-merger business plan of the Institute includes the integration of fisheries research in inland waters under this research axis.
