重在预防

Prevention is Key

要饲养兰寿的话，所有人都会为鱼生病感到烦恼。越晚发现患病，鱼的生存率越低。早期发现、早期治疗自不必说，但在这之前最重要的是不要让鱼得病。为了明确预防的方法，在这里列出疾病预防的五大原则。

Everyone who want to feed Ranchu will be bothered by sickness of the fish.The later discovery of illness, the lower rate for fish to survive. What matter most is to keep fish healthy, needless to say early detection and treatment .Here,the five principles are listed in order to clarify the method of prevention.

原则1 饲养水的维持、管理不能懈怠

Principle 1 Maintaining and managing the feeding water should not been let up

饲养水槽是兰寿唯一的生存环境。饲养水的状态与兰寿的健康息息相关。导致鱼得病的原因，除了从外部引入的特定病原体之外，就只有饲养水的管理不足了。

Feeding trough is the uniqe living environment for Ranchu. The condition of feeding water is closely related with Ranchu’s health.The only cause lead to fish disease is the lack of management,except of a specific pathogen from the outside.

原则2 多加注意防止引入疾病

Principle 2 Pay more attention ,or you will lead in disease 不论如何努力管理水质，如果带入了疾病就前功尽弃了。从外部引入疾病的途径有放入

了外来的兰寿、使鱼混养等。在这时使用的网和容器也是原因之一。放入外来的鱼时，不但要作药浴，还要分开饲养一个季度。

If infect disease,no matter how efforts we have put to manage water quality, all the work we've done will be wasted.The approachs infecting diseases from outside are as follows: put a foreign Ranchu into the water, polyculture of fish and so on.even the using net and container this moment is also one of the reasons. Not only to make medicine bath, but also keeping a separate quarter when leading the foreign fish.

原则3 进行预防药浴

Principle 3 Preventive medicine bath

不同季节，鱼容易得的疾病也不同。如果了解疾病的早期症状，不但可以实现早期治疗，还可以通过药浴进行有效预防。

In different seasons, the diseases the fish suscepted are also different. If you know the early symptoms of the disease, not only early treatment can be achieved, but also can be effective in preventing drug bath.

原则4 避免喂食过多饵料

Principle 4 Avoid of feeding too much bait

过多的饵料不但会加重内脏的负担，也会导致水质的腐败。要让鱼吃到八分饱，注意保持水质的稳定。

Too much feed would not only increase the burden of internal organs, water quality will lead to corruption. Allow fish to eat eight to keep the water quality stable.

原则5 经常留意健康情况

Principle 5 Pay attention to health frequently

知识固然十分重要，但也要会活学活用。这就要靠平时的观察了。可以通过体表、泳姿、鳃部的运动等了解鱼的健康状态并迅速采取对策，防止鱼得病。

请牢记以上疾病预防的五大原则！

Knowledge is certainly important, but also will live for everyday by usual observation. Through the surface, swimming stroke, gill movement, etc. to find out the health of fish, and take prompt measures to prevent the fish getting sick.

Keep in mind of the five principles of disease prevention above!

季节的变化与疾病

Season changes&Disease

A.春季的疾病

A、the spring disease

到了春天，兰寿从冬眠中醒来。由于冬眠中没能进食，免疫力较为低下。这个时期需要注意的是由于饵料投放过多导致的肠炎以及由于水质腐败导致的细菌和原虫的滋生。15℃以下的冷天停止投饵，天气暖和时也需注意不要有剩饵。这一时期需要注意的有白点病(Ich ）、烂尾病(tail-rot disease)、水霉病(Saprolegniasis)等，如果在早期发现是比较容易治愈的。

In spring, Ranchu have a lower immunity when they wake up from hibernation without eating something. Note that this period should note enteritis caused by putting too much bait and breeding of bacteria and protozoa because of corruption of water quality. Stop feeding when the weather downs b elow 15 ℃,and make sure there have no leftover bait when the weather is warm. During this period ,it should be noted that there are Ich, tail-rot disease, Saprolegniasis and so on, it is relatively easy to cure if have a early detection.
