Comparative Survey of Morphometric-meristic Male and Female Anjak Fish (Schizocypris brucei, Annandale and Hora, 1920) of Hamoun Wetland in South East Iran

The species named schizocypris brucei belongs to the cyprinidae family and of fish that has native economic value to the southeastern regions of Iran. Surveying specifications of morphometric-meristic fish in Hamoun wetland and Chahnimes Iran was done in breeding season (April 2010) and after fishing with a spring net 11 mm, a total of 36 specimens of this species transferred to the laboratory. The results of morphometric- meristic survey showed that these fish have an average total of 18.5±1.99 cm length, 55.5±14.45 g weight and 1.4±2.42 year. The mean number of lateral line scales is 92.1±8.95 and the number of vertebrate is assigned 42±5.38. Mean head length is 3.2±0.40 cm, length of caudal fin is 2.6±0.36 cm, the distance pre-anal is 11.3±1.40 cm, diameter of eye is 0.5±0.11 cm, the distance between the eye is 1.0±0.16 cm, mean standard length is 15.4±1.70 cm, the mean fork length is16.9±1.73 cm, maximum height body is 2.9±0.42, height and length of dorsal fin is 3.1±0.50, 1.7±0.32 cm respectively, height and length of the anal fine is 1.00±0.24, 2.6±0.62 cm respectively, the length pectoral fins is 2.2±0.31cm, fins abdominal is 1.8±0.31cm, distance of the fine pectoral-abdominal is 4.1±0.52 cm and abdominal-anal is 3.5±0.5 cm were calculated. Also sex and morphometric-meristic specifications of the type of each male and female was compared and it was found that male and female are different in 20 morphometric factors and 2 meristic factors. Overall, little difference between the minimum and maximum total length and total weight, very low growth in the life of this fish and the low reproductive age is shown.
