    观赏鱼致病的主要原因
    来源:http://www.yunsyb.com  2015-01-29 14:43:49
    1.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;
    1 water quality, water temperature, fish to water imbalance of physicochemical properties of the adaptation: if the unit water fish carrying too much capacity, ecological environment is very harsh, more than survival adaptation range, then the disease 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 water, excreta, secretions of the fish too much carbon dioxide, ammonia increased, microbial breeding, blue green algae phytoplankton growth too much, can make the water quality deterioration, dissolved oxygen content is reduced, so that the 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 water temperature suddenly changes, temperature difference is more than 4 DEG C; the water temperature exceeds the range of adaptation of the upper or lower, and water temperature in a short time or long period variable, the water temperature is low, will make the fish disease.
    2.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。
    2: ornamental fish because of improper feeding of artificial feeding, if cast feed nutrition feed shortage, such as long-term feeding dry feed, the lack of animal bait, lack of protein, vitamins, trace elements, or not quantitative timing, hunger and satiety unevenness, the fish malnutrition, physical weakness and disease. And feed mildew metamorphic, fish poisoning.
    3.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。
    3 careless operation: in the clear box and water for breeding cylinder fish etc. in the process of operation, the operation of rough, accidentally bumps fish fins, broken, or the fish jumped down to the ground were injured, injured easily infection. The other is always blowing attached algae eating fish, the snout is easy to infection.
    4.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。
    4 external pathogens: many ways into external pathogens into the fish container, such as by food, aquatic plants into, the sick fish used tools without disinfection and for disease free fish, buy new fish without isolation observation into the original fish can bring pathogens.
    5.还有一个是鱼群中的打斗致伤而引起病变。
    5 there is a fish fight injury caused by disease.
