本文报道了方斑东风螺人工育苗试验.方斑东风螺亲螺日摄食率5～8%,亲螺夜间产卵,具卵囊,每个卵囊含卵约1千粒,以卵囊柄粘附于池底,呈悬浮状态。在水温28.0～29.0℃,盐度29的条件下,受精卵孵出卵囊的时间5～7d。浮游幼虫投喂角毛藻,孵化第13d开始出现变态的稚螺。浮游期壳长日均生长67.5μm。池底铺沙培育稚螺,变态15d的稚螺,壳长可达3mm。
In this paper, the artificial breeding test of M.album variegatus was reported.The inoculation rate of Proboscan moniliforme was 5-8%, and the progenitor spawned at night, with oocysts containing about 1000 eggs per oocyst, Attached to the bottom of the pool, was suspended. Under the conditions of water temperature of 28.0 ~ 29.0 ℃, salinity of 29, the fertilized eggs hatch the oocysts for 5 ~ 7 days. Floating larvae feeding Chaetoceros, hatch 13th metamorphosis juveniles. The average daily growth of shell of floating period was 67.5μm. Sand bottom pool to cultivate juvenile snails, metamorphosis juvenile snail 15d, shell length up to 3mm.
