The aim of ecosystem-based fisheries management is to provide the maximum sustainable take of target organisms with the minimum impact on other ecosystem components. The challenge of the approach is that in the developing countries, including Turkey stock assessments have been made only for a tiny minority of stocks with the rest of these being categorized as "data poor stocks". The main problem for data poor stocks are to provide a proper data for presenting the stock conditions and make any recommendation to fisheries managers, stakeholders and fishermen. Based on this motivation, we focus on the question: Can we successfully develop an ecosystem based management scheme for the data poor fish stocks in Eastern Mediterranean? CMSY method based on surplus production modeling was used to estimate fisheries reference points in a maximum sustainable yield (MSY) framework for the stocks. Results showed that 60% percent of the stocks were subject to ongoing over-fishing and 30% of them were outside of safe biological limits, potentially suffering from impaired reproduction. Only 8% of the stocks fulfilled the requirement of the CFP as being not subject to over-fishing and having a biomass above the level that can produce MSY.
