Abstract

Adriatic Sea has a characteristic sea current circulation which flows northward along the eastern coast and southward along the western coast. This circulation affects the river Po plume spreading. River Po is the main source of nutrient input into North Adriatic Sea. This input causes eutrofication. Moreover, eutrofication causes increase in primary production, hypoxia and increase in phytoplankton biomass. Also, increase in primary production favours nutrition of anchovies and its larval stages while, on the other hand, hypoxia is not favourable for specific fish species. Human activity brings these nutrients into North Adriatic Sea via river Po, especially because of industry and agriculture. Correlation between nutrient input and fish behaviour is evident, in a complex ecosystem.
