Stocks’ overexploitation and socio-economic sustainability are two major issues currently at stake in European fisheries. In this view the European Commission is considering the implementation of management plans as a means to move towards a longer-term perspective on fisheries management, to consider regional differences and to increase stakeholder involvement. Adriatic small pelagic species (anchovies and sardines) are some of the most studied species in the world from a biologic perspective; several economic analysis have also been realised on Italian pelagic fishery; despite that, no complete bioeconomic modelization has been carried out yet considering all biologic, technical and economic issues. Bioeconomic models cannot be considered foolproof tools but are important implements to help decision makers and can supply a fundamental scientific basis for management plans. This research gathers all available information (from biologic, technologic and economic perspectives) in order to carry out a bioeconomic model of the Adriatic pelagic fishery. Different approaches are analyzed and some of them developed to highlight potential divergences in results, characteristics and implications. Growth, production and demand functions are estimated. A formal analysis about interaction and competition between Italian and Croatian fleet is examined proposing different equilibriums for open access, duopoly and a form of cooperative solution. Anyway normative judgments are limited because of poor knowledge of population dynamics and data related to the Croatian fleet.
