在对虾育苗过程中,受精卵孵化一般有两种方法:一是网箱孵化,受精卵孵化后将无节幼体撇入育苗池培育;另一种方法是将收集来的受精卵直接放入育苗池孵化,一直培育到仔虾出苗。这两种孵化方法,前者操作繁杂,又要占去一部分水体;后者因坏卵易沉底腐败,育苗池水质和无节幼体密度都不易控制。另外,上述两种方法都易造成虾卵堆集,卵膜和无节幼体会受到不同程度的伤亡,将直接影响孵化率。
In the shrimp nursery process, the hatching of fertilized eggs are generally two ways: First, the cage hatch, after hatching nosocomial nauplii into the nursery pond breeding; the other method is to collect the fertilized eggs directly into the nursery Pool incubation, has been nurtured to larvae emergence. The two incubation methods, the former complex operation, but also take up a portion of the water; the latter due to bad eggs easy to sink at the bottom of corruption, nursery pond water quality and nauplii density are not easy to control. In addition, the above two methods are likely to cause the accumulation of shrimp eggs, egg and nauplii will be subjected to varying degrees of casualties will directly affect the hatching rate.
