Title

EFFECT OF FEMALE AGE, LENGTH AND WEIGHT ON ARTIFICIAL PROPAGATION EFFICIENCY IN KUTUM BROODS (RUTILUS FRISII KUTUM, KAMENSKII 1901) MIGRATING TO THE SHIROUD RIVER

Pages

Abstract

 Kutum (Rutilus frisii KUTUM) is one of the economically valuable fishes in the Caspian Sea. This fish enters the rivers leading to the Caspian Sea for spawning. One of these rivers, which the fish migrate to, is SHIROUD RIVER. In the ARTIFICIAL PROPAGATION process of KUTUM, different factors are involved in quality and quantity of female broods and their eggs. For this target, in the propagation season of 2008 we studied the effect of AGE, LENGTH and WEIGHT on ARTIFICIAL PROPAGATION efficiency in KUTUM broods migrating to SHIROUD RIVER. For this reason, from February to May 2009 we studied the AGE, LENGTH and WEIGHT of 90 female KUTUM. According to the results, average of total LENGTH was 43.26 cm, average of WEIGHT 832.08 grams, average of AGE 4.41, average of egg diameter 1.85 ml, average of egg number 294.49, average of absolute fecundity 41370, average of relative fecundity 52, average of fertilization percentage 93.55. Also, according to Kruskal wails test and Man-Whitney, there was a significant difference between AGE and total factors. Relationship between AGE and total factors was linear and weak to average, but relationship between fork LENGTH and WEIGHT with total factors were weak to strong.
