家鱼人工繁殖中因催产操作不慎,亲鱼相互猛烈追逐或捕捞网具粗糙等原因,产后亲鱼尤其是性情暴躁的鲢亲鱼脱鳞、体表受伤充血现象十分普遍,特别是经多次注射或人工受精的亲鱼更为严重。据调查统计,每年因亲鱼受伤感染水霉菌而死亡的约占催产亲鱼总数的3％—5％,个别渔场高达20％。亲鱼死亡既造成重大经济损失,又导致性比失调,影响来年配对催产。故产后亲鱼防治水霉病是家孵生产中的重要一环。而常规方法有注射抗菌类药物,在体表涂抹抗菌素软膏,还有的用3％的食盐水浸洗。上述方法使用效果均欠佳。1992
Artificial reproduction of domestic fish due to improper operation of oxytocin, fierce mutual pursuit of broodstock or rough fishing nets and other reasons, postpartum broodstock, especially the gruff fish, silverfish deworming, surface injury, congestion is very common, especially after multiple injections or Artificial insemination broodstock more serious. According to the survey, about 3% -5% of the total number of mothers and broodstock died each year due to the death of broodstock infected with water fungi, and up to 20% in some fisheries. The death of broodstock not only caused major economic losses, but also lead to sexual imbalance, affect the coming year pairing. Therefore, prevention and treatment of moldy broodstock after birth is an important part of hatchling production. The conventional method of injection of antibacterial drugs, antibiotic ointment in the body smear, and some with 3% saline immersion. The above methods are not effective. 1992
