Abstract
In this study, the body composition and fatty acid profiles of Salmo trutta macrostigma living under natural conditions in Anatolia were analyzed. The total crude protein, lipid, ash, dry matter and fatty acid profile of fish meat were determined. Crude protein, lipid, ash and moisture of Salmo trutta macrostigma were 19.92%, 3.461%, 1.18% and 75.11% respectively. The predominant fatty acids found in Salmo trutta macrostigma muscle were myristic acid (C14:0, 2.23), palmitic acid (C16:0; 18.81%), palmitoleic acid (C16:1, 8.82%), stearic acid (C18:0; 4.11%), oleic acid (C18:1 n9; 11.93%), linoleic acid (C18:2n6, 3,72%), linolenic acid (C18:3n3, 9.27%), eicosapentaenoic acid (EPA; C20:5 n3; 7.48%) and docosahexaenoic acid (DHA; C22:6n3; 7.69%).The Fatty acid composition analyses showed that wild Salmo trutta macrostigma consisted of 29.17% saturated (SFA), 21.58% monounsaturated (MUFAs) and, 31.21% polyunsaturated acids (PUFAs).
Highlights
Salmo trutta macrostigma naturally contain omega-3 (n-3) fatty acids; especially, eicosapentaenoic acid (EPA, 20:5 n-3) and docosahexaenoic acid (DHA, 22:6 n-3) which have beneficial effects on human health
There is no study on the body composition and fatty acid profile of Salmo trutta macrostigma which naturally exist in Körkün Brook, with abundant habitat, in Toros Mountain in Turkey
The main objective of this study was to attract attention of the fish farmers to the protection of this species by carrying out the proximate composition and fatty acid profiles of Salmo trutta macrostigma which is endangered in Körkün Brook and other brooks in Turkey
Summary
Salmo trutta macrostigma naturally contain omega-3 (n-3) fatty acids; especially, eicosapentaenoic acid (EPA, 20:5 n-3) and docosahexaenoic acid (DHA, 22:6 n-3) which have beneficial effects on human health. Due to this reason, the importance of lipids and fatty acid composition of fish has highly increased recently. The main objective of this study was to attract attention of the fish farmers to the protection of this species by carrying out the proximate composition and fatty acid profiles of Salmo trutta macrostigma which is endangered in Körkün Brook and other brooks in Turkey. The hunting force on the brown trout will decrease and this species will be increased thanks to farmers
