The present study was conducted toestimate the optimum dietary supplementation level of Chlorella powder as a feed additive to optimize growth of juvenile olive flounder, Paralichthys olivaceus. Four experimental diets supplemented with Chlorella powder (CHP) at 0, 1, 2 and 4% (CHP0, CHP1, CHP2, and CHP4, respectively) of diet as a dry-matter (DM) basis were prepared. Three replicate groups of fish averaging 1.1±0.02 g were fed one of the four experimental diets for 12 weeks. After the feeding trial, fish fed the CHP2 diet had a higher (P < 0.05) weight gain (819%) than did fish fed CHP0 (707%) and CHP1(712%); however, there was no significant difference between fish fed CHP2 (8197%) and CHP4 (7559%) as among fish fed CHP0, CHP1, and CHP4 (P > 0.05). Fish fed CHP2 had a higher (P < 0.05) feed efficiency (134%) than did fish fed CHP0 (123%); however, there was no significant difference (P > 0.05) among fish fed CHP0 (123%), CHP1 (125%), and CHP4 (125%) as among fish fed CHP1 (125%), CHP2 (134%), and CHP4 (125%). Fish fed CHP2 and CHP4 had a lower (P < 0.05) serum glucose level (average 32.9 mg/dL) than did fish fed CHP0 and CHP1 (average 34.8 mg/dL). Fish fed CHP1 and CHP2 had a lower (P < 0.05) serum glutamic oxaloacetic transaminase (GOT) level than did fish fed CHP0 and CHP4. Glutamic pyruvic transaminase (GPT) levels significantly (P < 0.05) deceased as dietary CHP increased. Fish fed CHP2 and CHP4 had a less (P < 0.05) whole-body fat than did fish fed CHP0. These results indicate that the optimum dietary supplementation level of Chlorella powder as a feed additive in juvenile olive flounder could be approximately 2% of diet. |
