초록

This experiment was conducted to evaluate the effects of different substrates in rearing tank on growth and body
composition of juvenile sea cucumber Apostichophus japonicus. Sea cucumber (average weight 3.6) were randomly
distributed at a density of 10 juvenile per tank into nine tanks providing three different substrates including
free-substrates, sand and wave-shaped plastic sheet as (shelter). Juveniles were fed with a commercial feed once
in every 2 days for 8 weeks. At the end of the experiment, survival of sea cucumber was not affected by the presence
of substrates (P>0.05). Weight gain and specific growth rate of sea cucumber reared in the tanks with sand
were significantly higher than those of sea cucumber reared in the tanks with shelter and without substrate
(P<0.05). Crude protein and crude lipid of whole body in sea cucumber reared in free-substrate tanks were significantly
higher than those of juvenile reared in the tanks with other substrates (P<0.05). Higher ash content was
obtained in sea cucumber reared in the tanks with sand compared to that of juvenile reared in the tanks with other
substrates (P<0.05). The results of this study suggest that growth and proximate composition of whole body of
sea cucumber was significantly affected by substrates. Among materials tested, sand may be a proper substrate for
sea cucumber culture.
