Long-chain omega-3 polyunsaturated fatty acids (LC-PUFA) essential for human nutrition are mostly obtained from wild fish catch. To sustain LC-PUFA supply from natural populations, one needs to know how environmental and intrinsic factors affect fish fatty acid (FA) profiles and contents. We studied seven Salmoniformes species from two arctic lakes. We aimed to estimate differences in FA composition of total lipids and two major lipid classes, polar lipids (PL) and triacylglycerols (TAG), among the species and to evaluate LC-PUFA contents corresponded to PL and TAG in muscles. Fatty acid profiles of PL and TAG in all species were characterized by prevalence of omega-3 LC-PUFA and C16-C18 monoenoic FA, respectively. Fish with similar feeding spectra were identified similarly in multivariate analyses of total lipids, TAG and PL, due to differences in levels of mostly the same FA. Thus, suitability both TAG and total lipids for identification of feeding spectra of fish was confirmed. All species had similar content of LC-PUFA esterified as PL, 1.9 - 3.5 mg · g-1, while the content as TAG form strongly varied, from 0.9 to 9.8 mg · g-1. The LC-PUFA-rich fish species accumulated these valuable compounds predominately in TAG form.
