Summary of the action: Demersal stocks in the Mediterranean are affected by overfishing and a poor exploitation pattern with high juveniles fishing mortality and high production of discards. To improve this status the Common Fishery Policy foresees the implementation of an Ecosystem-based Approach to Fisheries Management (EAFM) whilst ensuring that exploitation rates of living marine biological resources are able to restore and maintain populations of harvested species above levels that can produce the maximum sustainable yield (MSY). To increase the productivity of the stocks and their profitability, a key requirement is to rebuild the size- and age-structure of exploited populations by shifting the size of rst capture towards larger sizes. However, in the case of the trawl fishery, a noticeable increase in the mesh size of the cod-end would be required to substantially increase the size at first capture of species like hake and red mullet. This could led to negative implications on the catch rate of associated small-sized commercial species (e.g. shrimps). A possible management alternative is the reduction of the mortality rate of juveniles by protecting the areas/habitats were
