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.
