The risk of 'genetic pollution' in Mediterranean fish populations related to aquaculture activities

摘要

To the list of negative factors that affect marine biodiversity, such as habitat destruction, physical and chemical pollution, and introduction of exotic species, we must add "genetic pollution." By this we mean alteration of the natural genetic architecture and microevolutionary processes of wild populations due to the gene flow from farmed conspecifics that have escaped from aquaculture plants. This environmental problem created by aquaculture at the end of the last century was widely discussed at the World Conference of the NACA/FAO in Bangkok 2000.
