、有效用藥
，才能達到健康養殖的效果。

一、對症下藥

、氟呱酸、呋喃唑酮
、五氯酚鈉、孔雀石綠等。二是要針對病情選擇適當藥物。三是要防止不同養殖品種對藥物的過敏。

二
、時間適宜

藥物施用的時間一般在傍晚前，潑藥後，氣溫、shuiwenjiangdi，kejianshaoyuleideyingjifanyinghetinengxiaohao。ruguozaiqingchenpoyao，yinshuizhongrongyangchuyuzuidizhuangtai，yizaochengqueyangfutou。zaizhongwuyangguangzhisheshishiyong，huijiangdiyaoxiao。eryutianheleiyudiqiyatianqishibuyipoyao。

三、潑灑均勻

潑灑藥液，切不可定點傾倒，應用木瓢
、勺子等均勻潑灑。全池潑灑時應從上風處逐漸向下風處，使藥物潑灑均勻。尤其是池塘邊角容易被疏忽
，造成用藥不到的區域，殺菌、殺蟲不徹底，使魚病複發。

四、劑量精準

潑灑藥物要準確丈量水體；bansiliaodeyaowuyaojiaozhunquegujiyutizhong，yimianyongyaoguoliangzaochengzhongduhuoyongyaobuzudabudaozhiliaoxiaoguo。jisuanshuititijibuzhunhechengyaoliangbugou

五
、溶解藥物

潑灑藥物前要按要求用開水、溫水或冷水充分溶解，潑灑的藥物不能有顆粒或塊狀
、團(tuan)狀(zhuang)，以(yi)防(fang)藥(yao)物(wu)沒(mei)有(you)充(chong)分(fen)溶(rong)解(jie)，水(shui)體(ti)依(yi)然(ran)達(da)不(bu)到(dao)規(gui)定(ding)濃(nong)度(du)，或(huo)藥(yao)物(wu)顆(ke)粒(li)被(bei)魚(yu)誤(wu)食(shi)而(er)致(zhi)死(si)。如(ru)生(sheng)石(shi)灰(hui)要(yao)化(hua)漿(jiang)潑(po)灑(sa)，漂(piao)白(bai)粉(fen)不(bu)宜(yi)幹(gan)灑(sa)。溶(rong)解(jie)藥(yao)要(yao)注(zhu)意(yi)水(shui)溫(wen)，如(ru)殺(sha)蟲(chong)中(zhong)草(cao)藥(yao)要(yao)求(qiu)溫(wen)度(du)在(zai)60℃—100℃。

六、先喂飼料

潑(po)灑(sa)藥(yao)物(wu)不(bu)要(yao)投(tou)喂(wei)飼(si)料(liao)
，最(zui)好(hao)先(xian)喂(wei)食(shi)後(hou)灑(sa)藥(yao)。但(dan)在(zai)投(tou)喂(wei)藥(yao)餌(er)時(shi)，要(yao)使(shi)魚(yu)空(kong)腹(fu)，讓(rang)魚(yu)搶(qiang)食(shi)，以(yi)減(jian)少(shao)藥(yao)餌(er)在(zai)水(shui)中(zhong)滯(zhi)留(liu)時(shi)間(jian)
，以(yi)免(mian)藥(yao)物(wu)失(shi)散(san)在(zai)水(shui)中(zhong)
，造(zao)成(cheng)藥(yao)物(wu)浪(lang)費(fei)和(he)藥(yao)效(xiao)達(da)不(bu)到(dao)。

七、分別用藥

、硫酸銅、敵百蟲混用。酸性藥物和堿性藥物就不能混合使用。藥物在混用之前應先進行小水體試驗
，然後再進行大麵積使用，切不可盲目混用。

八
、浮頭勿動

魚在浮頭時或浮頭剛結束時，不要用藥，否則會造成大批魚死亡。

九
、注意有效期

十
、隨時應急

用藥前應做好一些應急措施準備，用藥後應在現場觀察2—4小時，不離開池塘邊，觀察魚情，注意是否有異常情況，一旦發現魚嚴重浮頭或不正常，應及時采取措施。
