Özet:

 

This  study  was  aimed  to  determined  the  effects  of  different  concentrations  of  canola  oil  (CO)  on  the  digestibility,   vicerosomatic  index  (VSI),  hepatosomatic  index  (HSI)  and  the  contents  of  fatty  acids  in  the  liver  of  rainbow  trout   (Oncorhynchus mykiss). Rainbow trouts were fed with the experimental diets for 70 days. The diets were given as triplicate   groups of rainbow trout (initial weight of 119 g) to apparent satiation twice in a day. There were not significant differences in   digestibility of protein and lipid between the experimental diets. VSI and HSI were not significantly different among the all   treatment and between the initals and the end of trials (P>0.05). Liver fatty acid contents of all groups were different from   each other. Liver fatty acid analyses showed that EPA and DHA from n-3 HUFA's in the fish fed by the fish oil diet (K) and   the initial liver samples, oleic acid (C18:1n-9, OA) and linoleic acid (C18:2n-6, LA) in the fish fed by the canola oil (C 50 , C 75 ,   C 100 ) were higher than in the fish fed by the control diet. Arachidonic acid (C20:4n-6; ARA) were 2.54, 3.15, 4.15, 4.63 and   5.64% in C 75 , K, C 100 , C 50 groups and initial, respectively. n3/n6 rate was quite high in all groups. 	 	 		 .
