Abstract: To compare the effect of different diets on the growth of sea cucumber with different specifications (the weight was 105.57，73.15 and 52.89 g，respectively)，three sizes of Apostichopus japonicas were fed with two diets，which were respectively composed of kelp feed stuff and gel form ulated diet，for 60 days. The results showed that the Specific Growth Rate (SGR) of three sizes of A. japonicas fed with kelp feed stuff were (0. 69±0.04)，(0.87±0.05) and (0.99 ±0.02) %?d -1，respectively，and that fed with diet of gel formulated were ( 0.65±0.03 )，(0.86±0.05) and ( 0.81±0.10) %?d -1，respectively. The daily weight gain ( WGr ) and SGR of A.japonicas fed with diet of kelp feed stuff were significantly higher than diet of gel form ulated in the group of small size，but there were no significant difference between the group of large and medium size. In summary，the kelp feed stuff could be used for the diet of A. japonicas，and the gel form ulated diet could be used as a supplementary die t of kelp feed stuff for raft culture of A. japonicas.
