摘要
为提高对虾亲虾眼柄摘除手术的存活率,比较使用弯头尖嘴钳和医用镊子进行对虾亲虾眼柄摘除手术的亲虾催熟期存活率。结果表明,使用弯头尖嘴钳手术时,日本囊对虾亲虾催熟期存活率为59.3%,明显高于使用医用镊子时的49.7%,存活率提高9.6%。使用弯头尖嘴钳手术时,斑节对虾亲虾催熟期存活率为93.3%,存活率明显高于日本囊对虾。尖嘴钳用于眼柄摘除手术的技术改进,有助于提高育苗生产的亲虾存活率。
In order to increase the survival rate of eyestalk ablation of penaeid shrimp broodstoek, a comparison experiment was conducted to compare the survival rate of eyestalk ablation of Marsupenaeus japonicus broodstock in ripening period using snip nose pliers with stainless steel nippers. The results showed that when snip nose pliers were used, the survival rate was 71.2%, which was olwiously higher than the stainless steel nippers of 60.6%（P〈0.01）, with a 9.6% increase of the smwival rate. And the survival rate was 93.3% with snip nose pliers in the eyestalk ablation of Penaeus monodon broodstoek, obviously higher than the survival tale .f Marsupenaeus japonicus. The eyestalk ablation using snip nose pliers improved the smwival rate of broodstock whieh is for breedirlg and production.
