摘要
在福建沿海,皱纹盘鲍秋季人工育苗效果明显优于春季育苗。采取异地引进亲鲍、用面积1m2的透明塑料薄膜培养硅藻饵料并用于采苗,薄膜投放密度14片/m2,担轮幼体布池密度10×10^4-15×10^4个/m^2等技术措施,匍匐幼体平均采集密度200-300个/片,稚鲍的前期培育时间可延长至44d,剥离规格达4.64 mm;稚鲍剥离至池底水泥板上进行继续培育,培育密度2000-2500个/m^2,至壳长10 mm时成活率可达79%;平均单位面积出苗量1200个/m^2。
It was much better for artificial breeding of disk abalone Haliotis discus hannai in autumn than in spring in coast in Fujian province.Firstly,the creeping larvae with over 4.64 mm in shell length were collected at an average density of 200-300 individuals per plastic piece in the delayed 44 d rearing period by the key technique including introduction of the different broodstock resources,the diatom culturing with transparent plastic film of 1 m^2 and,using the 14 pieces of film per square meter in the tank at the density of 10×10^4-15×10^4 inds/m^2.Then,the abalone juveniles were stripped to the floor slab at the bottom of the tank to continue breeding at a the density of 2000-2500 inds/m^2 until they had a shell length of 10 mm,with survival rate of 79% and the yield of 1200 inds/m^2 on average.
