The effect of different feeding levels (1.2%, 1.4%, 1.8% and to satiety) on the growth skill, morphological indexes and chemical composition of the dorsal muscle of rainbow trout (Oncorhynchus my-kiss) have been investigated. Significant differences were observed for the morphological indexes which increased with feeding level. For instance, the increase of feeding level induces a decrease in moisture content in the muscle composition, which corresponds to an increase of fat. Feeding level modified phospholipids, triglycerids and fatty acids content. These results can be of potential interest for the consumer from a diet point of view, and for the fish processing industry, since the processing and safe preservation of finished products are strictly linked to the chemical characteristics of fresh product.
