Abstract :Beneficial effects of omega-3 insert ignore into journalissuearticles values(ω-3); fatty acids are consistent of long chain polyunsaturated fatty acids insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(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% insert ignore into journalissuearticles values(±0.11);. The results showed that the polyunsaturated fatty acids insert ignore into journalissuearticles values(PUFA); such as eicosapentaenoic insert ignore into journalissuearticles values(EPA); and docosahexaenoic insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(30.74%);, oleic+elaidic acids insert ignore into journalissuearticles values(27.84%);, palmitic acid insert ignore into journalissuearticles values(19.63%); and EPA insert ignore into journalissuearticles values(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.
