Abstract：The effects of partial replacement of sea weed Sargassum pallidum meal by peanut vine powder on growth and digestibility were studied in juvenile sea cucumber Apostichopus japonicus .The sea cucum‐ber juveniles w ere fed the diets containing the sea w eed meal w hich w as replaced by peanut vine pow der at 0% (control group) ,8% ,16% ,24% ,32% and 40% with triplication for 60 days .The results showed that there was survival rate of over 95% in all groups ,without significant difference (P>0 .05) .It was found that the sea cucumber in group 24% replacement had the maximal specific grow th rate (0 .58% /d) , 28 .9% higher than that in the control group .There was poor growth in the juveniles in group 8% replace‐ment and group 16% replacement than than in the control group without significant difference ( P >0 .05) ,significantly lower in group 32% replacement and group 40% replacement that in the control group (P < 0 .05) .There were no significant differences in concentrations of COD ,ammonia‐N and NO2 -N in the water between the replacement groups (P>0 .05) and the control group .The digestibility was found to be decreased in the juveniles fed the diets containing more peanut vine pow der ,higher protease and am‐ylase activities in alimentary canal in the early 30 days than in the later 30 days .The maximal protease ac‐tivity was observed in the juveniles in the control group ,being lower with the larger replacement ratio . There were no significant differences in activities of superoxide dismutase and alkine phosphatase in the coelomic fluid between the replacement groups and the control group (P>0 .05) .
