摘　　要：2007年11月至2008年1月在浙江南麂岛利用低位坑道水泥池进行了真蛸养殖试验。结果表明:8口水泥池共放养真蛸1200头,体重范围165.0～622.5g,平均体重329.2g,经过40d养殖,体重范围325.0～1095.0g,平均体重达595.8g,平均每头真蛸增重266.6g,日均增重6.665g,日均增重率达1.441%,养殖成活率72.50%,饵料系数为6.97,投入产出比为1∶1.159。此外,还探讨了不同放养规格、密度及不同种类蛸巢对养殖效果的影响。Between November 2007 and January 2008, culture experiment of Octopus vulgaris was carried out in cement pools in a lower tunnel in Nanji Island, Zhejiang Province. 1 200 octopuses, whose original weight was from 165.0 g/ind to 622.5 g/ind, averaging 329.2 g/ind, were euhured in 8 cement pools. In 40 days, their average weight rose to 595.8 g/ind in a range of 325.0 g/ind to 1 095.0 g/ind, with the daily gain and daily gain ratio of 6.665 g and 1.441% respectively. The survival rate was 72.50%. The feed coefficient was 6.97, and the input-output ratio was 1：1.159. Effects on euhure efficiency exerted by different stocking size, culture density and type of octopus nests were also discussed.
