초록/요약
This study was conducted to investigate the proper dietary protein and lipid level for growth and body composition of juvenile sea cucumber (Stichopus japonicus). Three replicate groups of the sea cucumber (average weight of 1.1 g) were fed the experimental diets containing four protein levels (10, 20, 30 and 40%) and three lipid levels (3, 7 and 11%) for 10 weeks. At the end of the feeding trial, survival of each group was over 87% and there was no significant difference among the groups. Weight gain and specific growth rate (SGR) of sea cucumber were significantly affected dietary protein (P<0.005) and lipid levels (P<0.005). The highest weight gain and SGR were observed when sea cucumber fed the diet containing 30% protein with 3% lipid (P<0.05). Weight gain and SGR of sea cucumber fed the diet containing 3% lipid were higher than the other groups at the same protein level except for 40% protein groups (P<0.05). Protein content of sea cucumber fed the diet containing 30% protein with 3% lipid was significantly (P<0.05) higher than those of sea cucumber fed the 20% protein diets with 7% or 11% lipids and 10% protein diet with 7% lipid, but was not significant different from that of sea cucumber fed the other diets. Moisture, lipid and ash contents of the whole body were not significantly different among the groups. The results of this study indicate that the diet containing 30% protein and 3% lipid is optimal for growth of juvenile sea cucumber.
