[Diet effect on fatty acids composition in trout (salmo gairdnerii). rev. esp. fisiol., (author's transl)].

The effect of diets with different fatty acids composition on muscular and hepatic fatty acids of rainbow trout (Salmo gairdnerii) was studied. The effect was higher on muscular fatty acids than on hepatic ones. The lack of correlation between dietary and liver fatty acids in diets with a high level of linoleic acid, showed a better utilization of this acid by the liver. The change in muscular fatty acids pattern was observed within a week of diet change, showing a significant tendency to approach the new dietary fatty acids pattern.
