Abstract :

Abstract Cyprinus carpio L., 1758 is one of the economic value species of Caspian sea. Nowadays, for conservation and restocking of this species artificial propagation methods is considered. Thus study of some of biological characters is needed. In these study 165 individuals of fishes examined for record of biometric data and age determination. Male fish’s length and weight ranges were 253-660ml and 265-3670 gr, respectively. Also female fish’s length and weight ranges were 305-602ml and 310-2900 gr, respectively. Age rane of all brooders were 2-14 years. Absolute fecundity ranges were calculated 77447-430745 eggs. Decreasing of age groups and aged individuals of brooders may be related to unsuitable reproduction and feeding conditions of their habitats and overfishing, thus fisheries management on the southern coastal waters of Caspian sea is necessary.
