Abstract

 In this study was conducted with rainbow trout of land and fresh water in autumn and winter in Tajan River downstream areas. Duration of study was in November to March at 120 days. Two size frequencies were measured of 34. 91± 14. 0 SE and 60. 90± 13. 0 SE g) with 3 replicates of 200 individuals in a pool of 16 m2 with a sprinkling of aeration and water flow of 2. 0 LPs. feeding took placed at three times due to high turbidity, so using floating extruded feed. Fish nutritional and water physicochemical parameters were measured. The data showed that only in 5 warm months (June to September) water temperature was recorded less than 20° C which showed suitable condition for salmon rearing. Data expressed only two parameters, turbidity and suspended solid were determined over the standard limitation. Therefore, planktonic organisms due to opacity factor had no impact on Fish growth. The present study showed due to suitable initial weight of the storage, there was a significant difference between growth and nutritional parameters in both one and two experimental treatments, survival rate (respectively 91. 5 and 93. 83), condition factor (respectively 1. 34, 1. 14), feed conversion ratio (respectively 1. 37 and 1. 66), specific growth rate (respectively 1. 63 and 1. 39) and protein efficiency ratio (respectively 1. 69, 1. 39) (P <0. 05), Although both treatments showed appropriate amounts than conventional breeding conditions.
