随着鲍鱼海上筏式养殖规模的扩大,出现了大面积的死亡现象。为了控制病害的发生和蔓延,笔者现结合生产实践,将如何降低筏养鲍鱼死亡率的关键措施介绍如下,供养鲍者参考。 (一)选用优良鲍苗 鲍鱼养殖海区相近,容易造成近亲繁殖,种质退化,急需改良品种。生产上利用杂交、转基因、克隆、多倍体育种等技术应用于鲍鱼育苗工艺中,已培育出了具有抗病力强、适应 With the expansion of abalone’s sea-raft culture, there has been a large-scale death. In order to control the occurrence and spread of disease, the author now combines production practices, will be how to reduce the cadaveric abalone mortality rate of the key measures introduced below, to provide a reference for the abalone. (A) the selection of fine abalone abalone farming sea area is similar, likely to cause inbreeding, germplasm degradation, the urgent need to improve varieties. Production of hybrid, transgenic, cloning, polyploid breeding technology used abalone seedling technology, has been bred with a strong disease resistance, adaptation
