🐡淡水フグQ&A - 淡水フグに関するご質問お答えします！ -

Ｑ：
My Pao abei has become sick I think and I don’t know what to do. I hope you can help me.
A few weeks ago she developed a little white spot above her snout, yet it has developed so far that the white is occupying her entire head.
I have never seen this before and normal treatments don’t solve the problem.
Do you perhaps know what to do and are willing to help me?
Greetings,



Ａ：
In Japan, this condition is called Shirakumo disease, also known as Costia or Chilodonella disease.
Costia (Costia necatrix) or Chilodonella (Chilodonella) is a medical condition that infects pufferfish when they become ill due to stress or other factors.
It can also be transmitted by a drop in water temperature or deterioration of water quality.
The disease often occurs when a heater is not installed during the change of season or when the temperature is easily changed.
Treatment includes salt water baths and methylene blue, which is used to treat white spot disease.
It is also important to treat the water temperature and water quality deterioration that caused the stress.

日本では、白雲病と呼ばれている症状で、Costia症やChilodonella症とも呼ばれます。
フグがストレスなどで体調を崩したときにコスティア（Costia necatrix）やキロドネラ（Chilodonella）が感染する病状です。
水温低下や水質悪化などでも感染します。
季節の変わり目など気温が変わり易い時期にヒーターを設置していない場合によく発症します。
治療は塩水浴や白点病などを治療するときに使うメチレンブルーなどを使います。
またストレスの原因となった水温や水質悪化などを直す事も大切です。
