Dark muscle tissue of farmed rainbow trout (Oncorhynchus mykiss Walbaum) was found to have a higher total lipid content than light muscle—73 vs 30 g kg −1 —which was mainly due to a higher content of neutral lipids. In accordance with this the phospholipid content in the dark muscle tissue was 322 g kg −1 of total lipids compared with 569 g kg −1 in light muscle tissue. Lipids from light muscle tissue contained higher percentages of polyunsaturated fatty acids than the dark muscle lipids, and docosahexaenoic acid was the major fatty acid present.
