Abstract

Seasonal variations of proximate composition and fatty acid profiles of wild brown trout (Salmo trutta macrostigma Dumeril, 1858) caught from the Munzur River, Tunceli-Turkey were investigated in this study. It was determined that wild brown trout was high in mono-unsaturated, poly-unsaturated and saturated fatty acids, respectively. C18:1 omega-9 (oleic acid) was the most abundant fatty acid in all seasons ranging from 20.27 to 29.35 %. C22:6 omega-3 (docosahexaenoic acid-DHA), C18:3 omega-3c (cis-linolenic acid), C18:2 omega-6c (linoleic acid), and C20:5 omega-3 (eicosapentaenoic acid-EPA) were found to be predominant fatty acids in PUFAs. As a conclusion, wild brown trout living in Munzur river could be considered as an important protein and omega-3 fatty acid source according to the nutritional quality results evaluated in terms of proximate and fatty acid composition.
