探讨了大银鱼胚胎发育过程中 ,不同水源对水霉病发生的影响及几种抗菌药物的防治效果。结果表明自来水是一种良好的孵化用水。在水霉病发生后 ,甲醛、孔雀石绿、强力霉素、痢特灵及氯霉素具有较好的抑菌作用。尤其是甲醛、孔雀石绿和强力霉素。但从孵化率来看 ,痢特灵组和氯霉素组孵化率较高。为了有效抑制水霉病蔓延 ,通过搅拌或强充气等方式阻止菌丝缠绕好卵是一条有效的途径 The effects of different water sources on the occurrence of watery mildew and the control effects of several antimicrobial agents in the process of embryonic development were discussed. The results show that tap water is a good hatching water. In the water mold disease, formaldehyde, malachite green, doxycycline, furazolidone and chloramphenicol has good antibacterial activity. In particular, formaldehyde, malachite green and doxycycline. However, from the hatchability rate, furazolidone group and chloramphenicol group hatching rate higher. In order to effectively inhibit the spread of water mold, by stirring or strong aeration to prevent mycelial wound eggs is an effective way
