一、水霉病 病因:发生在20℃以下的低水温季节。奥尼鱼进入越冬期时,因鱼体的损伤、鳞片脱落,导致水霉菌入侵,在受伤及病灶处迅速繁殖,长出许多棉毛状的水霉菌丝。病鱼焦躁不安,游动缓慢,食欲减退,鱼体消瘦终至死亡。 防治方法:(1)越冬池要严格消毒后才能放鱼。(2)水温应保持在20℃以上,做好保温升温工作。(3)在捕捞搬运和放养时尽量避免鱼体受伤,注意合理的放养密度。(4)入
First, the cause of watery mildew: occurred in the low temperature below 20 ℃ season. When the Omani enters the wintering period, the flakes fall off due to the damage of the fish body, leading to the invasion of the water fungus and rapidly multiplying the wounds and lesions to grow many cottony mycelia. Diseased fish restlessness, slow swimming, loss of appetite, weight loss to death. Prevention and treatment methods: (1) winter pool disinfection should be strictly after the fish. (2) water temperature should be maintained at above 20 ℃, do a good job of warming temperature. (3) Try to avoid the fish from being injured when handling and stocking. Pay attention to the reasonable stocking density. (4) into
