The effects of three lectins from Undaria pinnatifida lectin, Ulva pertusa lectin and Scytosiphon lomen-tarius lectin on the activities of Superoxide dismutase ( SOD) , Polyphenol oxidase ( PO) of Apostichopus japonicus were studied by supplying various lectin .The experimental dietary levels of Undaria pinnatifida lectin were 0.90%( m/m), 1.80%and 3.60%, and Ulva pertusa lectin were 1.36%、2.73%、5.45%, and Scytosiphon lomentarius lectin were 0.47%、0.94%、1.88%respectively, Group fed with basic feed was set as control .On the 5th, 10th, 15th and 20th day after feeding, the activities of Superoxide dismutase (SOD) and Polyphenol oxidase (PO) in Apostichopus ja-ponicus were determined .The results indicated that the activities of SOD and PO of each group increased ,respectively , has a significant difference (P <0.05) and a highly significant difference (P <0.01), with the control group.Feed-ing 1.80% concentration group of Undaria pinnatifida lectin;1.36% concentration group of Ulva pertusa lectin;1.88%concentration group of Scytosiphon lomentarius lectin are best.The results show that marine algae lectin can be used as the Apostichopus japonicus immune enhancer , it is recommended that the appropriate dosage:1.80%Undaria pinnatifida lectin, 1.36%Ulva pertusa lectin and 1.88%Scytosiphon lomentarius lectin.
