Two are the main sub actions of the proposed action: Sub-action 1: Exploitation of non-marketable fish Trawlings result in a high amount of discard (40%-50%). There is a need to utilize and manage these resources more efficiently either for direct human consumption or for use in feeds for aquaculture. It has been estimated that 10%-20% of the total catches is undersized specimens of marketable species. An example is the catches of Pagrus pagrus at the gulf of Heraklion at 2.500.000 fish annually, weighing between 30-50g.The situation is comparable with other species such as Dentex dentex, Diplodus sargus, Lithognathus mormyrus etc. From the total catch almost no specimens survive of those returned to the sea. On the other hand, research results show that 30%-75% of these fish can survive if they are introduced to tanks after handling (sophistication of tanks determines survival rate). The collected populations can subsequently be reared in aquaculture facilities until marketable size. The remain of the discard can be used as food for the reared populations. For the implementation of the work package pilot rearing of fish collected during 20 fishing expeditions will be performed. The rearing will take place at the aquaculture facilities of IMBC at Heraklion as well as in facilities prepared for this purpose in the gulf of Souda. Sub-action 2: Exploitation of species with high growth rate Studies of the Cretan ichthyofauna showed that the region is a reproductive field for Seriola dumerili and Polyprion americanus as well as for members of the centrolophidae family such as Schedophilus ovalis, unknown in Greek fishery. Due to their particular high growth rate these species are very interesting for aquaculture as they reach 1,5Kg (S. dumerili) to 2,5Kg (P. americanus) per year (in comparison to sea bream or sea bass which reach 150-200 g annually). Fishing is performed either with purse-line or with the use of FAD ( Fish Aggregating Devices). Their catching size is usually small (20-60g) and thus nonmarketable with the exception of S. dumerili. The rearing of these species could be particularly effective, as it does not requires large populations (due to their large final size). Furthermore, caught fish that are not harmed display high survival rates facilitating the creation of farmed stock is not difficult. Furthermore, the study of the behavior of these species in the wild can contribute to actions for re-population or sea ranching. For the implementation , pilot rearing will be performed with fish caught by fishermen or with experimental surveys conducted in Heraklion and Souda. During the implementation Local Fishermen Unions in collaboration with the Directorate of Fisheries at the prefectural level will organize seminars and workshops in order to raise awareness and for the dissemination of the results of the action. Furthermore, the partnership will participate in relevant European networks of island regions for the exchange of experience and information.
