通过亲蚕强化营养促熟培育和精心挑选亲蚕,集中同步产卵,缩短双齿围沙蚕人工育苗的时间,提高受精卵的质量；按照♀∶♂=3∶1配比产卵,孵化密度为1500~1800万粒/m3,孵化率达80%以上。本试验经60 d培育,在1200 m2的培育面积中育出5~6 cm 沙蚕幼体2812万尾,单位面积出苗量为2.34万尾/m2,底栖后至出池成活率为50%,平均产量约1250 kg/亩。
通過親蠶彊化營養促熟培育和精心挑選親蠶,集中同步產卵,縮短雙齒圍沙蠶人工育苗的時間,提高受精卵的質量；按照♀∶♂=3∶1配比產卵,孵化密度為1500~1800萬粒/m3,孵化率達80%以上。本試驗經60 d培育,在1200 m2的培育麵積中育齣5~6 cm 沙蠶幼體2812萬尾,單位麵積齣苗量為2.34萬尾/m2,底棲後至齣池成活率為50%,平均產量約1250 kg/畝。
통과친잠강화영양촉숙배육화정심도선친잠,집중동보산란,축단쌍치위사잠인공육묘적시간,제고수정란적질량；안조♀∶♂=3∶1배비산란,부화밀도위1500~1800만립/m3,부화솔체80%이상。본시험경60 d배육,재1200 m2적배육면적중육출5~6 cm 사잠유체2812만미,단위면적출묘량위2.34만미/m2,저서후지출지성활솔위50%,평균산량약1250 kg/무。
Perinereis aibuhitensis could be breeded artificially earlier by means of nutritional enhance-ment and choosing ripening parent (♀∶♂= 3∶1 ).The larvae were properly controlled at a hatch density of 15~18 millions/m3 .Totally 28.12 millions larva with body length about 5~6 cm were yiel-ded from a water volume of 1200 m2 after 60 days.Output of seeding was 2.34 thousands/m2 in unit ar-ea.Survival rate from demersal was 50% and average yield was about 1250 kg/acreage.
