FATTY ACIDS PROFILE IN CARASSIUS SPP. FROM LAKE GOPŁO, POLAND
FATTY ACIDS PROFILE IN CARASSIUS
AbstractEffects of sex and age on fatty acids profile in the meat of Carassius spp. were evaluated. Carassius auratus fillets displayed a higher content of SFA and MUFA than Carassius carassius. In contrast, Carassius carassius had a higher content of PUFA (higher proportion of linoleic, arachidonic, eicosapentaenoic, docosatetraenoic and docosapentaenoic acids) and total n-3 and n-6 PUFA, compared with Carassius auratus. Moreover, γ-linolenic acid was higher in fillets from Carassius auratus. What is more, fillets from females had a greater content of eicosapentaenoic acid than males. Finally, 4-year-old fish had a lower content of ALA, higher MUFA content and better nutritional indexes (n-3/n-6, AI) than 3-year-old fish.
