Abstract: Considering its economic and halieutic interest, the rainbow trout (Oncorhynchus mykiss, Walbaum, on 1792) is one of the species the most appreciated in the world, in particular for the sports fishing. To compare the effects of two food of different formulation, (the one premises(place) used by the center of salmon farming and the other one imported) on some biological parameters of the trout rainbow, an experimental study was realized between 1st Mars and June 15th, 2016 in the National Center of Hydrobiology and Fish farming of Azrou on 2000 fish fry stemming from the same prize of eggs and restarted randomly in 4 rectangular ponds fed with fresh water and fed four times by days during 107 days. The obtained results show good that the best performances of growth in length and in weight, the survival rate and feed efficiency are attributed to the imported food.
