Beneficial effects of
omega-3 (ω-3) fatty acids are consistent of long chain polyunsaturated fatty
acids (PUFA) on human health have been well understood issue during the last
decade. Freshwater gammarids known as a natural source of PUFA and some of fish
especially salmonids (e.g. trout) feeding mainly on these crustacea, thus
became rich in these fatty acids. The aim of this work is to reveal of lipid
content and fatty acid composition of Gammarus
komareki that inhabiting in Kırkgözler limnocrene spring Northwestern
Anatolia, Çanakkale – Turkey. Total lipid of G. komareki was found 4.97% (±0.11). The results showed that the
polyunsaturated fatty acids (PUFA) such as eicosapentaenoic (EPA) and
docosahexaenoic (DHA) acids were found higher than monounsaturated fatty acids.
Total ω-3, ω-6 and ω-9 were 16.63%,
12.3%, and 29.41% respectively. PUFA (30.74%), oleic+elaidic acids
(27.84%), palmitic acid (19.63%) and EPA (9.45%) are predominant in G. komareki. According to our data, G. komareki has almost a higher content
of PUFA than the other Gammarids which live in the Europe and Asia. Thus, it
might be considered as an alternative source of PUFA and ω-3 fatty acids for
local aquaculture nutrition.
