Morphometric and electrophoretic comparison of Common carp (Cyprinus carpio L.) in north of Iran
M. Yosefian
In a research project during 1999-2000, transferrin polymorphism in blood serum as well as several morphometric and meristic characteristics were determined in 7 groups of carps of different fish farms. Transferrin polymorphism in carp is expressed by the occurrence of one or two band phenotypes determined by a series of codominant alleles. In this study, there was significant difference especially between sea andcultured carp (P<0.01). Sampling of sea carp in general have been from race of carp with BB dominant genotype, but fish sample from shahid rajaii fish farm have shown variety genotype including AA, AB, BB, AC, BC and CC. In morphological investigation, the C.V. of meristic characteristics, which is under genetic bases such as number of fin rays and number of scales on lateral line was higher significantly in those fishes caught from the sea than cultured fishes (P<0.00). Relative comparative of morphometric characteristics such as head length to standard length and width of body showed also significant difference between those two groups (P<0.05).
