    水质、水温失调、鱼对水体的理化性质的适应范围:如果单位水体内载鱼量太多,生存的生态环境很恶劣、超过适应范围,便可能发病。
    Water quality, water temperature disorders, fish on the physical and chemical properties of the water body of the scope: if the unit of water contained too much fish, the living environment is very poor, more than the scope of adaptation, it may be.
    不及时换水,鱼的排泄物、分泌物过多使二氧化碳、氨增多,微生物孳生,蓝绿藻类浮游植物生长过多,都可使水质恶化,溶氧量降低,使鱼发病。
    Not timely change the water, fish excreta, secretions of too much carbon dioxide and ammonia increased, microbial breeding, blue-green algae phytoplankton growth too much, the deterioration of water quality, reduce the amount of dissolved oxygen, fish disease.
    水温突然变动,温差超过4 ℃以上;水温超过适应范围的上限或下限,以及水温短时间内多变,或长时期水温偏低,都会使鱼发病。
    The sudden change of water temperature, the temperature difference more than 4 degrees Celsius; water temperature exceeds the upper limit or lower limit, as well as the water temperature in a short period of time, or a long period of low water temperature, will make the fish disease.
    饲喂不当:观赏鱼全赖人工投饲,如果投喂的饲料营养成分不足,如长期投喂干饲料,缺乏动物性饵料,缺乏蛋白质、维生素、微量元素,或者不能定时定量,饥饱不匀,使鱼营养不良,体质衰弱而致病。还有配合饲料霉败变质,鱼会中毒致病。
    Feeding improper: ornamental fish with artificial feeding, if the lack of feeding the feed nutrients, such as long-term investment and dry feed, a lack of animal food, lack of protein, vitamins, trace elements, or be able to timing quantitative, hunger and satiety unevenness, fish malnutrition, physical decline and weak pathogenic. There are complex feed mildew degeneration, fish poisoning.
    操作不慎:在清箱换水、繁殖分缸捞鱼等操作过程中,操作粗糙,不慎碰伤鱼体,折断鱼鳍,或使鱼跳落于地上受伤,伤部极易感染。另常刮食附着藻的鱼,吻部也易感染。
    Careless operation: the box for water, reproduction cylinder is divided into fishing fish operation process, rough operation, accidentally bumps the fish body broken fins, or the fish jumping and falling on the ground injured, the injured very susceptible to infection. Another common scraping algae attached to the fish, the kiss is also easy to infection.
    外部带入病原体:将外部病原体带入养鱼容器的途径很多,如由饵料、水草带入,病鱼用过的工具未经消毒又用于无病鱼,新购鱼未经隔离观察就放入原来的鱼群等都能带入病原体。
    External into pathogens: external pathogens into the fish container in many ways, such as food, aquatic plants into, sick fish used tools not disinfected and for disease-free fish, buy new fish without isolated for observation into the original fish can be brought into the pathogen.
