Fishery sector of the two sides of the northern Adriatic sea is interested by strong socio-economic barriers, despite the geographical closeness and the common historical background between Italian and Balkan coasts. Problems to be solved in the Northern Adriatic Sea fishery sector are essentially traceable to the mutual lack of information about social and economical aspects, together with a chronicle deficiency of structures. This is also the cause of the up to now non respect of European rules and regulations concerning sustainable fishery in the Northern Adriatic sea. Therefore, fishery policies should pay primary attention upon alternative operators' incomes, exploiting existing potentialities in the area, in order to encourage the adaptation to the in force laws. This can be reached through a ccordinated qualification and diversification of fishery activities in Italian and Balkan coasts, in order to give the chance to local enterprises to develop and compete in different markets. Expected Results: The most important result of the ADRI.FISH project is the establishment of the Social-Economic Observatory of Fisheries in the Northern Adriatic Sea located in Chioggia (Italy). Today the Observatory employs a transnational staff and plays an important role in co-ordinating the fishing activities as it has become the centre for surveying and analysing social and economic data related to the fisheries sector. The Observatory pays special attention to production, market trends, employment and consumption. A database and statistical reports were created to support the work of the Observatory. Moreover, a transnational feasibility study for the identification of strategic areas suitable for structural interventions was made, focused on the technical evaluation of a proposal for the right typology, dimension, cost of logistics and commercial structures in the Northern Adriatic Sea. In addition to this, the first Fishers' Association in the Istrian region and the first Fishers' Centre in Izola were established and transnational training measures for promoting and marketing fishing products were organised. A specific section for the Socio-Economic Observatory was included on the ADRI.FISH website (available in Italian, English, Croatian and Slovenian) and a regular ADRI.FISH newsletter was published.
