在对虾育茁生产中,由于卤虫卵价格大幅度上升,造成育苗成本上升.笔者经几年的实践,认为卤虫卵经孵化后再去壳,其用量可节省25%左右,具体方法为:1.孵化在使用前1～2星期,对卤虫卵进行淘洗消毒,然后装袋放入冷库进行低温冷藏备用.使用时,取出解冻(稍晒),进池孵化,此时充气量应调至最大位置,卵应均匀撒开,水温调至27～30℃,卤虫的孵化与虾苗的培育应同步进行.囟虫无节幼体要适当投饵,添加肥水,并用稀疏法控制其密度.
In shrimp breeding, the price of brine shrimp eggs due to a substantial increase, raising the cost of raising nursery.The author after several years of practice, that the brine shrimp hatch after shell, its dosage can save about 25%, the specific method is : 1. Hatching 1 to 2 weeks before use, panning and disinfecting Artemia eggs, and then bagged into cold storage for cold storage. Use, remove the thaw (slightly drying), into the pool hatch, then the amount of inflation Should be transferred to the maximum position, the eggs should be evenly spread, the water temperature was adjusted to 27 ~ 30 ℃, Artemia hatchlings and shrimp breeding should be carried out simultaneously .Flora insect nauplii should be appropriate to feed, add fertilizer and sparse method control Its density.
