Tartalmi leírás:
This study investigated the effects of a six-week starvation period on the fatty acid profile, body composition and blood parameters of intensively reared pike (Esox lucius). 150 pike were stocked in an experimental recirculating aquaculture system (RAS) and feed was completely withdrawn. Body composition, fatty acid composition and blood parameters (serum protein, albumin, triacylglycerol, cholesterol concentration and Lactate dehidrigenase and alkaline phosphatase activity) were measured and somatic indices were calculated. A significant decline in bodyweight, crude fat content and somatic indices was accompanied by a significant decrease of blood triacylglycerol content. The relative proportion of saturated fatty acids in the fillet decreased, while polyunsaturated fatty acids increased. There was also a significant increase in the average chain length and unsaturation index of fatty acids found in the fillet flesh.
