Genetic homogeneity of dolphinfish (Coryphaena hippurus) in the western Mediterranean and the eastern Atlantic

Dolphinfish (Coryphaena hippurus) is an epipelagic, highly migratory specie s distributed worldwide in tropical and temperate waters including the Medi terranean Sea. Protein electrophoresis analyses can provide knowledge of th e genetic population structure of the species and therefore be used as a to ol for fishery management. Areas sampled include the islands of Majorca and Sicily in the western Mediterranean and the Canary Islands in the eastern Atlantic. The results of the protein electrophoresis reveal a level of gene tic variability similar to other highly migratory species. No differences w ere found among locations, and it was not possible to reject the null hypot hesis of one panmictic population in the area studied.
