Effects of Habitats and Feeding Patterns on Fatty Acid Profile of Rainbow Trout (Oncorhynchus mykiss)
Effects of Habitats and Feeding Patterns on Fatty Acid Profile of Rainbow Trout (Oncorhynchus mykiss)
In this study, fatty acid profiles of rainbow trout, which has been bred in farms, and the trouts escaping from the farm to the nature (fish living in the canal between the farm and the Körkün Brook) and, which escaped from the farm and reached the Körkün Brook and fed here with natural nutrients have been compared. The rainbow trout obtained from the culture medium and the trout escaping from the farms to the nature were found to be significantly different in the fatty acid profile. The basic fatty acids of the samples taken from our research groups are; myristic acid (C14: O-), palmitic acid (C16: 0), palmitoleic acid (C16: 1), heptadecenoic acid (C17: 1), stearic acid (C18: 0), oleic acid (C18: 1 n9), linoleic acid (C18: 2 n6), vaccenic acid (C18: 1 n7), linolenic acid (C18: 3 n3), arashidic acid (C20: 0), arashidonic acid (C20: 4n6), eicosapentaenoic acid (C20: 5 n3), eruric acid (C22: 1 n9), docosahexaenoic acid (C22: 6 n3). In our study, saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids were determined respectively; 29.389-21.451%, 25.36-59.49% and 34.17-18.56%. As a result, the habitats and feeding of the fish affected the fatty acid profile of rainbow trout.
