1  EFFECTS OF DIETARY INCLUSION OF CHLORELLA VULGARIS ON GROWTH, BLOOD BIOCHEMICAL PARAMETERS AND ANTIOXIDANT ENZYMES ACTIVITY IN OLIVE FLOUNDER, PARALICHTHYS OLIVACEUS  Samad Rahimnejad1, Heum-Gi Park2, Sang-Min Lee1* Department of Marine Bioscience and Technology, Gangneung-Wonju National University, Gangneung 25457, Korea Department of Marine Resource Development, Gangneung-Wonju National University, Gangneung 25457, Korea  ABSTRACT This study was carried out to investigate the effects of dietary inclusion of defatted Chlorella on growth performance, body composition, blood biochemistry and antioxidant enzymes activity in olive flounder. Four isonitrogenous (51% crude protein) diets were formulated to contain 0 (control), 5, 10 or 15% Chlorella meal (CM) (designated as, Con, CM5, CM10 and CM15, respectively) and fed to triplicate groups of fish (104.4 g) to apparent satiation twice daily for 8 wk. At the end of feeding trial, significant enhancement (P <0.05) in growth performance was obtained at over 10% CM compared to fish fed the control diet. No significant changes in dorsal muscle and liver proximate compositions were found following CM administration. The groups fed CM containing diets revealed significantly lower plasma cholesterol concentration than those fed the control diet. Dietary CM affected antioxidant enzymes activity; significantly higher plasma catalase activity was found in fish fed ≥10% CM and total antioxidant capacity increased in CM5 and CM10 groups compared to control. However, plasma glutathione peroxidase and superoxide dismutase activities were not significantly influenced by dietary CM. Also, significant enhancement in DPPH radical scavenging activity was found in dorsal muscle of fish fed CM15 diet compared to control. The findings in this study showed that dietary inclusion of 10-15% CM can enhance growth performance, and affect antioxidant enzymes activity and lipid metabolism in olive flounder.
