- Abstract
The fatty acid (FA) profiles of edible muscle of selected commercially important freshwater and marine fish species from Turkey were investigated. The fatty acid compositions of freshwater fish species were 23.00–29.60% saturated (SFA), 25.70–36.50% monounsaturated (MUFAs), and 26.59–31.92% polyunsaturated acids (PUFAs), whereas the fatty acid compositions of marine fish consisted of 21.08–36.90% (SFA), 18.03–51.45% MUFAs, and 20.92–53.17% PUFAs. There was a wide variation and significant ( P < 0.05) differences among the fatty acid profiles of the freshwater and marine fish samples, including differences in the SFA, MUFA, PUFA, EPA, DHA, DHA/EPA, total n-3 PFAs, total n-6 PUFAs and n-3/n-6 values. In addition, the cheap marine fish species such as anchovy and European pilchard, bogue are better dietary sources of n-3 PUFAs than more expensive species such as bluefish, Atlantic mackerel, sea bream and sea bass. Through the application of two multivariate statistical methods, Principal Component and Hierarchical Analysis, fish species from Turkey waters were classified according to the geographical locations categorized in terms of fatty acid profiles. Clustering by fish species also gave rise to defined groups.
