为了筛选金鳟受精卵孵化期间水霉感染的有效防治药物,比较研究了2种自组中药复方(A和B)及2种化学除菌剂(过氧乙酸和过氧化氢,C和D)3种消毒浓度下的作用效果。将金鳟发眼卵随机分为13组,每组2个平行,每个平行1 000粒卵,选取适当的高、中、低浓度对鱼卵进行浸泡消毒,每天1次,每次持续35 min,每日消毒前进行活卵、死卵(霉菌感染死亡及其他原因死亡)计数,实验结束后,对每组存活发眼卵进行计数。结果表明:本实验所选用的2种自组中药复方和2种化药除菌剂对金鳟受精卵孵化期间水霉病的防治均有一定效果,且表现出一定的浓度相关性。经筛选,B中剂量组、C中剂量组和D高剂量组效果最为显著,但是考虑化药后期残留及对发眼卵的潜在危害,建议选择中药复方B进行金鳟受精卵水霉病防治,以进一步实现健康绿色养殖。选用中药复方B进行消毒时,应严格保证其消毒浓度及作用时间,以确保较好的消毒效果。 In order to screen effective control agents for the infection of watery mildew during the incubation period of the golden brown trout, two kinds of self-combination traditional Chinese medicines (A and B) and two kinds of chemical agents (peracetic acid and hydrogen peroxide, C and D) Effect of 3 kinds of disinfection concentration. The eye of the golden trout eyes were randomly divided into 13 groups of two parallel to each group 1 000 eggs each parallel, select the appropriate high, medium and low concentrations of soaked egg disinfection, once daily, each time for 35 min. Live ovulation, dead eggs (death caused by mold infection and death from other causes) were counted before daily disinfection. After the experiment, the number of surviving eggs in each group was counted. The results showed that the two kinds of self-combined traditional Chinese medicine compound and two kinds of chemical agents were selected in this experiment have certain effect on the prevention and control of watery mildew during hatching of the golden oyster fertilized eggs, and showed a certain concentration-related. After screening, B medium dose group, C middle dose group and D high dose group have the most obvious effect. However, taking into account the late residue of chemical drugs and the potential damage to the eye eggs, it is suggested that traditional Chinese medicine compound B should be used to prevent and cure , In order to further realize healthy green farming. Selection of traditional Chinese medicine compound B for disinfection should be strictly guaranteed its disinfection concentration and the role of time to ensure better disinfection.
