Seeking for a sustainable exploitation of the populations of commercialy valuable fish species without causing danger to their genetic resources it is necessary to amass extensive data about the population genetic structure of this fish species.

Original primer pairs Ang1 and Ang2 have been designed for the mtDNA analysis of the eel. On the basis of the Anguilla genus species mtDNA D-loop region data obtained during work it can be stated that inland and territorial water bodies of Lithuania contain no A. japonica and A. rostrata species.
