Abstract

Kutum (Rutilus frisii kutum) is an economically valuable fish in the Caspian Sea. The fish enters to the rivers leading to the Caspian Sea for spawning. One of these rivers, is SHIROUD RIVER. In the ARTIFICIAL SPAWNING process of Kutum, different factors involved in quality and quantity of female broods and their eggs and also the best TEMPERATURE and MIGRATION time for spawning. For this reason, in spawning season, the influence of TEMPERATURE and MIGRATION time on some of fecundity indices and fertilization rate of females in SHIROUD RIVER were studied. In this study, 90 individuals of female were studied from February to May 2008. Averages of total length, weight and age were 43.26 cm, 832.08 g, and 4.41 respectively. Results showed that maximum average egg diameter (1.86 mm), number of eggs in each gram of body weight (309.12), relative fecundity (56.21) and fertilization rate (95.82 %) obtained from 5 to 20 April (15.95°C). Maximum average of ovary weight (201.00 g) and absolute fecundity of eggs (49987.18) obtained from 6 to 20 March (17.74°C). Relationship between TEMPERATURE and MIGRATION time with fecundity indices was linear and weak.
