Abstract: 

The Kutum, Rutilus frisii, is the most important bony fish inhabiting the South of Caspian Sea so that the populations of autumn form gravely shrinked and neared to be extinct. This research implemented to finding of artificial reproduction biotechnic and restocking damaged population of autumn form Kutum in Caspian Sea. The autumn form of Kutum brooders caught from Bandar Anzali harbor to entrance Nahang-Roogah River in Anzali Wetland. The brooders held in two different conditions include of floating cages in Anzali Wetland and earthen pond for adaptation and complete gonad maturation. Male to female ratio was 1 to 1.4. Minimum and maximum weight were 1450 g and 3100 g with average of 1850 g in female and 670 g and 1900 g with average of 1165 g, respectively.  For artificial spawning, male and female brooders injected by carp pituitary extract with dose of 2-3 and 4-5 mg/kg body weight, respectively. Mean number of absolute, practical and relative fecundity determined as 88565±16809, 73805±14008 and 48670±12056. Dry method used for eggs fertilization, mean of fecundity was measured 97.3±3.2% and incubation period lasted 7 to 10 days in temperature of 14 to 16oC. Larvae introduced into fertilized earthen ponds (500 m2) in intensive condition (3 million /ha). Period of the larvae nutrition and fries culture in earthen ponds lasted 3-4 months. Finally, autumn form kutum fingerlings of 1-2 g produced and released into Anzali Wetland to its restocking for first time.
