This study to 6 weeks and at the center of proliferation and bony fish Syjuval Bandar Turkman in Golestan province was on Cyprinus carpio. Experiments in four treatments and three replications were as follows: Treatment 1: control, treatment 2: 3% zeolite of food weight, treatment 3: 6 % zeolite of food weight, treatment 4: 9 % zeolite of food weight. Feeding rate of 10 percent based on total body weight of fish a repeat a day. Given the importance of the physical and chemical factors and their impact on water supply and ultimately the fish growth, these factors were so controlled through the experiment that the amount of dissolved oxygen has always been fixed on 5.5 - 6 ppm, the temperature 26 andplusmn; 2 0C and pH 7.5 to 8. Cyprinus carpiofingerlings during the test meal containing SFC: 8.7% moisture, 11.2% Ash, 32% protein and 10.5% fat, were fed. According to the results of this study were identified between treatments were weight and body length observed differences are statistically significant (p andlt; 0.05). Maximum weight and length as the maximum amount of GR, % BWI and SGR in the treatment 3 and the lowest were in the control group. While no significant differences in FCR, CF and survival were observed (p andgt; 0.05). The results showed that the use of zeolite improved growth in Cyprinus carpio.
