The use of molecular methods in fisheries

The existence of high diversity between fish populations and species, among which some are not completely defined (for instance species of genus Cobitis), as well as negative human influence through overexploatation, non adequate fish stokings and changes of natural habitats, both ensured the fact that fish entered into the focus of many molecular biological investigations. In this paper we give the rewiew of the most used techniques in the differentiation of fish populations, including their advantages and weaknesses. The problem of the reduction of genetic diversity in freshwater (for instance common carp, Cyprinus carpio) and marine (for instance seabass, Dicentrqrchus labrax) aquaculture is also discussed.
