Abstract

EU fisheries sector suffers of low economic viability while European Commission has proposed adoption of new managerial approach on the sector. After the World Summit on Sustainable Development took place in Johanensburg in 2002, E.U. member states among others, commit their self to manage their fisheries in the basis of principle of Maximum Sustainable Yield (MSY), that is the optimal quantity of products taken out from the stock without compromise its capacity to regenerate for the future. Nowadays the majority of fishing stocks are in “overfishing” status, which means that there is a surplus of fishing effort in European fishing fleets. This surplus of effort by economic point of view defined as overcapitalization of fisheries sector (many boats, many gears). Technical Efficiency is critical for any Fisheries managerial scheme to be successful. Technical Efficiency looks for the optimal combination of inputs to achieve a given combination of outputs. Empirical measurement of technical efficiency falls possible through the estimation of parametric production functions and of non – parametric production functions. Two differed methodologies (DEA and SPF) were used in Greek Middle Scale fishing vessels to conclude that both methods can provide information for vessels technical efficiency. Three different types of fishing vessels were tested like trawlers, mixed vessels (acting both as trawlers and purse seines) and finally purse seines. Current research resulted various fleet segments technical efficiency, type of data needed to measure fleet’s technical efficiency, the characteristics of technical efficient fishing vessels and finally the capacity utilization of the same type of fishing vessels. Finally the advantages and disadvantages of each methodology are provided for Greek Middle Scale fishing fleet technical efficiency measurement
