摘要: 摘 要:真蛸为福建省近年来新兴的海水养殖优良种类,具有较高的营养价值、商品价值和产业化养殖潜景。本文报道了福建省水产研究所2008年~2011年真蛸人工繁殖及受精卵孵化结果:127头雌亲蛸经强化培育,共有77头产卵,获卵194万粒,孵出143.4万头浮游幼体。雌亲蛸获产率46.2%~86.7%,卵子受精率75.6%~91.8%,受精卵孵化率77.9%~95.0%。在20.0℃~22.5℃水温条件下,真蛸受精卵经21d~36d开始孵出,孵出后4d~6d为孵出高峰,每窝卵开始孵出至孵化结束维持10d~16d

Abstract: Abstract: Octopus Vulgar has a high nutritional value, commodity value and potential of industrial farming prospects,so it is considered as a new candidate for aquaculture in Fujian Province, China. In this study, the authors focus on the artificial propagation and hatchery technology of fertilized eggs of Octopus Vulgaris during 2008-2011.The resuits indicate that there were 77 femal broodstocks spawned 1940000 eggs in the 127 enriched femal broodstocks,and the hatched larvae were 1434000.the rates of spawning,fertilization and hatching rate were 46.2%-86.7%,75.6%-91.8% and 77.9%-95.0%. Under 20.0℃-22.5℃,it took 21d-36d from fertilization to hatching,the climax when larvae emerge from eggs is in 4th day to 6th day after hatching.The time lasts 10d-16d from the fist larve to the last one emerged in every ovarian.
