Abstract: The contents of proximate composition and trace elements were investigated in body wall of sea cucumberApstichopusjaponicuscollected from different regions (Dalian, Qingdao， Yantai, and Fujian) and farming methods (deep sea farming and captive farming). The sea cucumbers from different regions and farming methods was shown to have significant differences in the contents of protein, crude fat, crude ash and trace elements (Zn,B, Al, Cr, Mn and Cu)(P<0.05). The contents in the body walls were found to be 43.3%-55.3% of protein; crude ash of 1.7%-4.1%; crude fat of 23.9%-30.7%; 62.8-98.8 mg/kg of Zn; 25.5-44.8 mg/kg of B; 56.2-224.7 mg/kg of Al; 5.8-9.5 mg/kg of Cr; 16.1-29.2 mg/kg of Mn; and 1.5-4.0 mg/kg of Cu, as much twice Zn content (141.7-179.5 mg/kg) in the tendon as in the body walls. The maximal protein content was observed in the sea cucumber in captive farming from Fujian, the maximal crude ash content in captive farming from Qingdao, and the maximal crude crude fat content under captive farming from Yantai. The maximal Zn and Mn contents were found in the sea cucumber from Dalian, the maximal B and Cu contents from Yantai;and the maximal Al and Cr contents from Fujian. There were higher protein and crude fat contents in the sea cucumber under captive farming than those under deep sea farming from different regions. The contents of B, Cr and Cu, however, were higher in the body wall of the sea cucumber under deep sea farming than that under captive farming.
