解读危害养殖鱼类的病原性疾病 Pathogenic diseases of harm fish farming 损害饲养鱼类的病原性疾病首要有病毒性疾病、细菌性疾病和寄生虫性疾病等。其间病毒病因为其病原体细小，在宿主细胞内仿制，所以难以选用药物进行操控，一旦迸发病毒病将损失惨重，农业部新发布的《鱼类产地检疫规程》也将病毒性疾病作为要点检疫目标；一起北京市水产饲养首要是在静水池塘条件下饲养鲤、鲫、草鱼、鲟、观赏鱼以及在流水条件下饲养鲑鳟等鱼类为主，因而作者要点讨论北京市静水池塘和流水饲养条件下鱼类病毒病的防控技术办法。 Damage the primary pathogenic diseases breeding of fish with viral diseases, bacterial diseases and parasitic diseases. The virus disease because of its fine imitation of pathogens, in host cells, so it is difficult to choose drug control, once the outbreak virus disease would be disastrous, the Ministry of Agriculture issued a new fish quarantine rules for will also be viral diseases as points of quarantine target; with Beijing aquatic products is mainly reared under hydrostatic conditions Carp Ponds grass carp, crucian carp, ornamental fish, sturgeon, and feeding the trout in water under the condition of fish, thus the author point control technology measures of Beijing city water ponds and water feeding conditions fish virus disease. 鱼类病毒病发病与品种和水温有关 鱼类病毒病发病与饲养品种和水温密切相关。例如鲤春病毒血症首要在鲤中发作，发病温度为11～17℃，超越22℃不发病；锦鲤疱疹病毒病在鲤和锦鲤中发作，发病温度为23～28℃，低于18℃或高于30℃不发病；草鱼出血病在草鱼、青鱼中发作，在水温20～30℃特别是25～28℃时为盛行顶峰。 Fish virus disease incidence and pathogenesis of varieties and water fish viral diseases and breeding varieties and the water temperature is closely related to. For example, spring viremia of first episode in the carp, the onset temperature of 11～ 17 ℃, 22℃beyond not disease; Koi herpes virus attacks in common carp and Koi, the onset temperature of 23～ 28 ℃, below 18℃ or above 30 ℃without disease; grass carp hemorrhage in grass carp, herring attack, in the water temperature of 20～ 30 ℃is 25～ 28 ℃popular peak. 鱼类病毒病难以用药物操控,病毒性疾病不同于细菌性疾病，因为病毒不能本身增殖，有必要依托宿主细胞内的能量和物质增殖，是专性的细胞内寄生生物。因而可以医治细菌性疾病的抗生素等药物对病毒性疾病根本没有用果。鱼类一旦感染病毒性疾病，大多没有有用的药物医治办法，首要是以预防为主。 Fish viral diseases to drug control, viral diseases is different from bacterial disease, because the virus cannot itself proliferation, it is necessary to rely on the e
