Changes in fatty acid composition on tench (Tinca tinca L., 1758) captured in differnt seasons from the Seyhan dam lake

Seasonal changes in proximate composition the effects of fishing seasons onthe chemical and fatty acids composition of tench (Tinca tinca L.,1758) captured ain Nowember (2006), July (2007) and August (2007) from Seyhan Dam Lake wereinvestigated. It was found that the protein content of tench fillets inNowember(2006), July (2007) and August (2007) were 16.86%, 16.82%, 16.74%and lipid contents were 0.69%,1.05% and 1.22% respectively. The major fatty acidsof tench fillets in all groups were palmitik acid, oleic acid, eicosapentaenoic acidand docosahexaenoic acid. EPA content (in PUFA) of tench filet, were 12.28% inNowember, 25.94% in July and 14.26% in August. The DHA content (in PUFA) oftench fillet of Nowember (41.41%) was significantly higher (p<0.05) than thecontents in July (23.57%) and August (20.79%).
