Potential Contribution of Farmed Fishes to The Recommended Nutrient Intakes (RNIs): A Case Study of Farmed Atlantic Salmon (S. salar) and Different Origin Large Rainbow Trout (O. mykiss)

Abstract

In this study, different source species such as the large rainbow trout (O. mykiss) and Norwegian salmon (S. salar) were compared in terms of nutritional properties. The groups consisted of large rainbow trout of France-origin (Group A), large rainbow trout of local-origin (Group B) and imported Norwegian salmon (Group N). Group B had the highest crude protein content compared to the others. Group N's crude fat, protein and energy content was lower than that of Groups A and B. In the amino acid profile of the groups, lysine, glutamic acid and aspartic acid were determined at high rates, respectively. Group A's PUFA content was similar to that of Group N. The most important factor that makes Groups A and B superior to N, was the higher EPA+DHA, vitamin A, iron and selenium content. Accordingly, it was determined that the crude protein, crude oil, energy values and lysine, EPA+DHA, vitamin A, and selenium contents of large rainbow trout sampled from fish grown in the Black Sea were higher than Norwegian salmon.
