Mediterranean Aquaculture and Genetic Pollution: A Review Combined with Data from a Fish Farm Evaluating the Ecological Risks of Finfish Escapes

Mediterranean finfish aquaculture is mainly represented by the production of gilthead sea bream (Sparus aurata) and bass (Dicentrarchus labrax) growing in marine cage farms. Despite numerous benefits fish farming, ecological risk potentially caused escapes to wild populations occasionally high. In current study, an integrated review presented regarding S. aurata D. labrax their potential effect on genetic composition populations. The collected data from literature are combined discussed along with recorded a farm located Aegean Sea, Greece. According these records, present generally stable rate, ranging between 0 2% each escape event, which occur 5–8 times per year. Although for other farmed species worldwide, may be higher, this probably lower populations, characterized low levels differentiation. Nevertheless, introgression still exists. Particularly structure differentiation seem unaffected now. suitable management measurements would useful strategy avoid future negative effects escapes. These strategies should focused further efforts towards recapture program development, reduced escapees’ survival, proper legislation. Furthermore, more survival percentage, migration pathways, way pathways relate mortality, type season release also valuable.
