Abstract :

This research was conducted for 45 days at the Caspian Sea Aquaculture Research Center (Aquaculture Research Institute). Treatments included autumn and spring form, which were randomized and three replications. A total of 6 tests planes were used. Water was supplied from pumping water from the Caspian Sea coast. The meal was started with SFC1 Concentrate. The feeding rate was considered to be 4% of total weight. The results showed that the maximum and minimum amount of weight gains were occurred in race, autumn treatment (mean= 42.66±1.82) and spring race (mean= 31.92±8.24), respectively. The minimum average of FCR (4.13±0.11) was referred to race, autumn treatment and the maximum of that (5.18 ±1.41) was referred to spring race.
