摘　　要：进行了浒苔(Enteromorpha prolifera)的营养成分测定及投喂刺参(Apostichopus japonicus)的生长试验观察。营养成分检测结果显示,浒苔是一种高蛋白、低脂肪、矿物元素含量丰富的安全藻类食品。另外,分别以浒苔、海泥、浒苔∶海泥(质量比3∶7)、配合饵料∶海泥(质量比3∶7)4种饲料投喂刺参30 d。试验结果:浒苔∶海泥(3∶7)组既有最好的增重率,也有良好的成活率和健康状况;配合饵料∶海泥(3∶7)组次之;而单独投喂浒苔组或海泥组则表现较差。研究结果表明,浒苔具有良好的营养作用,可替代马尾藻、鼠尾藻、海带等作为一种优质的刺参养殖用饵料源。In this study,nutrition components of Enteromorpha prolifera were analyzed and sea cucumber（Apostichopus japonicus） feeding trial was conducted with this seaweed.The result showed that component of water,crude protein,crude fiber,fat and ash were 10.91%,10.22%,8.76%,0.37%,and 18.32% in the dried seaweed.The content of potassium,phosphorus,calcium,iodine,iron,magnesium,zinc,manganese and copper were 26 852.32,498.60,25 648.43,325.62,423.58,7 875.64,20.14,319.80,13.25 mg·kg-1,respectively.It indicated that E.prolifera was a kind of high-protein and low-fat seaweed with abundant mineral elements.It is also a kind of safe seafood as the content of lead,cadmium,inorganic arsenic,methyl mercury and polychlorinated biphenyl were much lower than the dose regulated in ＂algae products health standard＂ and ＂standard of feed hygiene＂.During the 30 days feeding trial,four groups of sea cucumbers were fed with mud,dried E.prolifera ∶ mud（mass ratio 3∶7）,artificial complex diet ∶ mud（3∶7）,dried E.prolifera,respectively.It revealed that the dried E.prolifera ∶ mud（3∶7） group had the highest growth rate and survival rate within the four experimental groups.In contrast,the sea cucumbers fed with mud or dried E.prolifera given poor growth and health conditions.This study proved that E.prolifera had good nutritional function and could be potentially used as high quality feedstuff for sea cucumber culture.
