一.做好产卵前及产卵期间亲虾疾病的预防工作健壮的亲虾是育苗的基本保障之一,只有优质的亲虾方能得到优质的虾卵,如想得到优质的亲虾,我认为应做到以下几点:1.选择个体较大、健壮无病的亲虾;2.要让亲虾在整个暂养过程中,有一个良好的环境条件,其中包括暂养密度、光照、水温及水质的理化因子。若发现亲虾有病,可用2ppm~3ppm 的土霉素或1ppm 氯霉素交替使用,连续使用三天基本痊愈;3.对虾卵消毒也是保证苗齐、苗壮的一个前提,虾卵消毒的过程是用网箱将虾卵收集起来,洗卵,用0.5ppm~0.8ppm 的孔雀石绿或200ppm~300ppm福尔马林浸泡,用过滤海水冲洗。这样即可以消除病原,又可以切断其传播的途径。
First, to do a good job before and during spawning broodstock disease prevention work Robust broodstock is one of the basic security nursery, only high-quality broodstock can get high-quality shrimp eggs, such as want to get high-quality broodstock, I The following points should be considered: 1. Choose a larger, robust and sick broodstock; 2. Make the broodstock have a good environmental condition throughout the holding process, including the holding density, light, Physical and chemical factors of water temperature and water quality. If you find that the broodstock disease, available 2ppm ~ 3ppm oxytetracycline or 1ppm chloramphenicol alternating use, three days of continuous use basically recovered; 3. Shrimp egg disinfection is to ensure Miao Qi, Miao Zhuang a prerequisite for shrimp egg disinfection The process is to use cages to collect shrimp eggs, egg wash, with 0.5ppm ~ 0.8ppm malachite green or 200ppm ~ 300ppm formalin soaked, washed with filtered seawater. In this way, the pathogen can be eliminated and the path of its transmission can be cut off.
