Fish (average initial weight 0.35±0.01g) were fed five experimental diets containing the following inclusion levels of PL: 0, 2, 4, 6 and 8%. Results showed that final body weight, weight gain and specific growth rate increased significantly (P<0.05) as dietary PL level increased from 0 to 6%, meanwhile the survival was not affected by dietary PL supplementation. Increasing dietary PL level significantly (P<0.05) increased in 20:4n-6 content in neutral lipid of liver, indicating fish had the capacity to convert C18 to C20 and C22 by elongation and desaturation. The expression levels of PPAR-α and PPAR-γ and the activities of catalase, superoxide dismutase and glutathione peroxidase in liver were significantly (P<0.05) increased, and liver thiobarbituric acid reactive substances value was decreased with dietary PL supplementation up to 6% compared with the control. Therefore, it was concluded that supplementation of 6% (18.8gkg−1, polar lipid of diet) PL could improve growth performance of blunt snout bream fingerlings.
