Abstract
For studying the biological characteristics and physical appearance, morphometric and electrophortic record information and the genetic study of Liza auratus are accomplished by polymorphism, Transferin, hemoglobin, total protein and the analysis of electrophoresis in the Babolsar and Fereydunkenar areas in the southern part of the Caspian sea in 2010. According to the random sampling of 50 Liza auratus from fishing in these areas (Babolsar and Fereydunkenar) and after observation of the variety in transferin of Liza auratus in these areas, ploymorphism tranferin appeared in the form of 1 or 2 band by the number of Codominants. Meaningful differences observed between fishes in both areas (Babolsar and Fereydunkenar)and the abundance of meaningful differences in Liza arautus from the Babolsar area was more than the and Fereydunkenar area. Genotypes comprise AA. AB. BB.AC. CC. BC. And all of the meristic and morphometric factors of fishes from the Babolsar area had more abundance than the Fereydunkenar area. In comparison with the caught samples in the Fereydunkenar area, Genotype BB had more abundance in the Babolsar area. According to these studies. The coefficient of variance for countable factors which are imporessed by genetic factors, like, (the number of fin rays and the number of up and down scale on the lateral line of fish from the Babolsar area had more abundance than the Fereydunkenar area. And so, in comparison with the proportion of morphometric factors, like, (the length of head, standard length and the height of body in the fishes that are caught from the Babolsar area) was more than Fereydunkenar area.
