Title: Determination of Biometry and Gonadosomatic Index in Male Khramulia (Capoeta capoeta gracilis, Keyserling 1861) in the Sefidroud River

This fish is a potamodoromous and spawning in rivers. The study of biometry and Gonadosomatic index is the important indicators of reproduction biology in fishes. The present study was conducted in spring of 2010 on 36 Khramulia specimens caught from each of 1, 2 and 3 years fishes, in the Sefidroud River to investigate Gonadosomatic index and biometry in this male species. According to the results obtained the highest mean of total length (186.67 mm), mean of fork length (173.67 mm), mean of standard length (160.5 mm), mean of weight (66.45 g) and ovary weight (1.902 g) belonged to 3-year specimens, while the lowest mean of total length (121.25 mm), mean of fork length (111.75 mm), mean of standard length (102.63 mm), mean of weight (21.81 g) and ovary weight (0.546 g) belonged to 1-year specimens. Among different age groups of fish were significant differences in mean of total length, fork length, standard length, weight and gonad weight (p 0.05). While there was no significant differences in Gonadosomatic index among these male broodstocks (P>0.05).Read More
