在工厂化对虾人工育苗中,亲虾是成功之本。如何管理好亲虾,特别是产卵后的亲虾,近年来各育苗单位都十分重视。在育苗期间当育苗室内的各水池布满卵后,往往都将亲虾处理掉。其原因一是室内暂养亲虾要占去部分水体;二是因室内(这时已是育苗后期)水温、室温都在不断升高而不便管理。所以产过卵的亲虾只好处理掉。如果幼体发育中出了问题,就会因无亲虾弥补而造成损失。
In industrialized shrimp artificial breeding, broodstock is the success of this. How to manage the broodstock, especially after the spawning broodstock, nursery units in recent years have attached great importance. After the nursery ponds are full of eggs in the nursery, the broodstock are often disposed of. The reason is that indoor rearing broodstock to account for part of the water body; the second is due to indoor (at this time is late nursery) water temperature, room temperature are rising and inconvenient to manage. Therefore, the pro-egg broodstock had to deal with it. If there is a problem in the development of larvae, it will be lost because of no broodstock make up.
