Abstract

BACKGROUND: Increase in aquatic production is dependent on raw materials, quality of diet, feed manufacture technology and optimum feed formulation. OBJECTIVES: The aim of this study was investigation and quality control feed of FFT, GFT1 and GFT2 of rainbow trout in farm and fish feed factory producers in Chaharmahal and Bakhtiari province. METHODS: In this study samples of FFT, GFT1 and GFT2 of diets were randomly taken from farm and fish feed factory producers in Chaharmahal and Bakhtiari province. Samples were analyzed for moisture, crud protein (CP), ether extract (EE), ash, phosphorous, TVN, Total count and coliform count. RESULTS: The results showed, diet CP was differs significantly (p<0.05) from many of the feeds. In addition nutrients of CP, phosphorous and EE of diets were differed slightly from rainbow trout requirement and in some cases were lower than instance requirement. The index of TVN that shows free nitrogen, was higher than standard in all samples. Total count and coliform count were different  between some of the other feed factories. CONCLUSIONS: Better management in fish feed factories  must be applied to balance the nutrient requirements  of the rainbow trout diet in different stages of growth, by using fresh, suitable and special feed materials.
