Abstract: Nutrient compositions were analyzed and evaluated in body walls of sea cucumber Apostichopus joponicus(body weight about 200 g) farmed in artificial reefs and ponds to understand the nutrient value of reef- and pond- reared sea cucumber. The results showed that there were significantly lower crude fatty, cholesterol, content and energy values (P<0.05) and significantly higher crude ash content (P<0.05) in the sea cucumber farmed in reefs than the one reared in the ponds, without significant differences in moisture and crude protein (P>0.05). However, the sea cucumber farmed in artificial reefs had significantly higher Na and Mg contents and significantly lower Ca, Fe, Cu and Mn contents in the sea cucumber farmed in the reef group than those in the ponds (P<0.05). The sea cucumber farmed in reefs had significantly higher total amino acids and total tasty amino acids contents than the sea cucumber farmed in ponds did (P<0.05), without significant difference in total essential amino acid content between the two groups. With the exception of Thr, both AAS and CS were found to be less than 1 in reef- and pond- reared sea cucumber. There were no significant difference in total saturated fatty acid and unsaturated fatty acid contents between reef- and pond- reared sea cucumber. However, the sea cucumber farmed in reefs had significantly lower C16:1 and C20:5n3 contents than the sea cucumber farmed in ponds did (P<0.05), without significant difference in other fatty acid contents between reef- and pond- reared sea cucumber. The findings indicate that the composition and content of nutrients and flavor substances in sea cucumber culture are affected by the culture pattern, the reef-reared sea cucumber is characterized by higher contents in protein, essential amino acid and tasty amino acids, and by lower content of fatty and cholesterol, superior to the sea cucumber farmed in ponds.
