1、防治魚病。

1. Prevention and control of fish diseases.

硫酸銅可用于防治原生動物引起的魚病（如：鞭毛蟲、卵鞭蟲病、隱鞭蟲病、魚波豆蟲病、毛管蟲病、斜管蟲病、纖毛蟲如車輪蟲病等）以及甲殼動物引起的魚病（如中華鳋病等）。

Copper sulfate can be used to prevent and treat fish diseases caused by protozoa (such as flagellates, egg whipworm disease, cryptoflagellate disease, fish wave bean disease, capillary disease, oblique tube disease, ciliates such as rotifer disease, etc.), as well as fish diseases caused by crustaceans (such as Chinese shrimp disease, etc.).

全池潑灑的用藥濃度：常與硫酸亞鐵配合使用，既又有效果。

The medication concentration for whole pool sprinkling: often used in combination with ferrous sulfate, which is both safe and effective.

春、秋季為0.7-1克/立方米，硫酸銅與硫酸亞鐵比為5∶2或6:2，硫酸銅單用時在1克/立方米以下。

In spring and autumn, it is 0.7-1 grams per cubic meter, and the ratio of copper sulfate to ferrous sulfate is 5:2 or 6:2. When copper sulfate is used alone, it is below 1 gram per cubic meter.

夏季應降到0.6~0.8克/立方米。用藥時間盡量全池均勻潑灑，用藥后要做好解救魚類浮頭的準備工作。

In summer, it should be reduced to 0.6~0.8 grams per cubic meter. Try to sprinkle the medication evenly throughout the pool as much as possible, and prepare to rescue fish floating heads after medication.

硫酸銅與高錳酸鉀（5：2）合用，在10度以下水溫時，濃度采用0.5-0.7克/立方米可斜管蟲病。

The combination of copper sulfate and potassium permanganate (5:2) at a concentration of 0.5-0.7 grams per cubic meter at a temperature below 10 degrees Celsius can treat the disease of Chlamydomonas obliquus.

硫酸銅與檸檬酸（3：2）合用，池水成0.15-0.20克/立方米可以小瓜蟲病。

The combination of copper sulfate and citric acid (3:2) can treat meloidogyne at a concentration of 0.15-0.20g/cubic meter.

硫酸銅0.7克/立方米，可越冬親蝦的纖毛蟲病。

Copper sulfate 0.7g/cubic meter can treat ciliate disease of overwintering parent shrimp.

硫酸銅0.7克/立方米和0.4克/立方米的撲草凈合用，先用硫酸銅，后用撲草凈與濕土（1：100）拌勻后潑灑可殺滅青泥苔。

Copper sulfate 0.7g/m3 and 0.4 g/m3 of chlorpromazine are used together. First, copper sulfate is used, and then chlorpromazine is mixed with wet soil (1:100) before sprinkling to kill green mud moss.

硫酸銅0.7克/立方米隔1天再用一次可殺滅輪蟲和椎實螺；間隔12小時再用一次可殺滅田螺、湖螺以及對蝦池赤潮生物（裸甲藻、三鞭藻等）。

Copper sulfate 0.7g/cubic meter can be used every other day to kill rotifers and snails; Once every 12 hours, it can be used to kill snails, lake snails, and red tide organisms in shrimp ponds (such as naked dinoflagellates and trichomonas).

硫酸銅1克/立方米，可殺滅水中輪蟲，以預防因輪蟲過度繁殖引起缺氧。

Copper sulfate 1 gram/cubic meter can kill rotifers in water to prevent hypoxia caused by excessive reproduction of rotifers.

硫酸銅0.5克/立方米與1克/立方米大黃合用，可細菌性疾病，隔3-4天再用一次可草魚出血病。

Copper sulfate 0.5 g/m3 combined with 1 g/m3 rhubarb can treat bacterial diseases, and can be used once every 3-4 days to treat grass carp bleeding disease.

2、魚(苗)種藥浴。

2. Fish (fry) seed medicinal bath.

常用藥浴濃度為8克/立方米的銅鐵合劑水溶液（即硫酸銅與硫酸亞鐵比為5∶2），硫酸銅8克/立方米加漂白粉10克/立方米合劑水溶液藥浴10-30分鐘。以上兩種配方均可以殺滅體表和鰓上細菌、原蟲，對未形成胞囊的粘胞子蟲也有效。

A copper iron mixture aqueous solution with a commonly used bath concentration of 8 grams/cubic meter (i.e. a ratio of copper sulfate to ferrous sulfate of 5:2), and a copper sulfate aqueous solution with a bleaching powder of 10 grams/cubic meter for 10 to 30 minutes. Both of the above formulas can kill bacteria and protozoa on the body surface and gills, and are also effective against myxocystis that have not formed cysts.

3、殺滅藻類植物，控制有害藻類生長。

3. Kill algae and control the growth of harmful algae.

硫酸銅可以用來抑制、殺滅池塘過多的藍藻和絲狀綠藻，也可以殺滅真菌和某些細菌。硫酸銅用于殺滅藍藻有效果，還可以用于防治微囊藻、卵甲藻引起的魚類中毒。全池潑灑的用藥濃度為0.7-0.9克/立方米（硫酸銅與硫酸亞鐵比為5∶2），硫酸銅還可用于青泥苔、螺蚌等和防治絲狀藻類附著引起的魚蝦蟹病。

Copper sulfate can be used to inhibit and kill excessive blue-green algae and filamentous green algae in ponds, as well as to kill fungi and certain bacteria. Copper sulfate is effective in killing blue-green algae and can also be used to prevent fish poisoning caused by Microcystis and Chlorella. The concentration of medication for the entire pond is 0.7-0.9 grams per cubic meter (copper sulfate to ferrous sulfate ratio is 5:2). Copper sulfate can also be used to remove green mud moss, snails, and clams, as well as to prevent and control fish, shrimp, and crab diseases caused by the attachment of filamentous algae.

用藥后要及時開動增氧機為宜，或在第二天清晨酌情加注清水。防止藻類死亡后，產生的有毒物質引起魚類中毒或缺氧泛塘。

It is advisable to start the oxygenator in a timely manner after medication, or add water as appropriate in the morning of the next day. To prevent toxic substances produced after the death of algae from causing fish poisoning or hypoxia flooding.

4、工具、食場。

4. Disinfection of tools and food facilities.

魚具用20克/立方米，硫酸銅水溶液浸泡半小時，可殺滅原蟲。

Fish utensils can be disinfected by soaking in 20 grams per cubic meter of copper sulfate aqueous solution for half an hour, which can kill protozoa.

食場可在魚病流行季節定期進行。每次用硫酸銅100克，硫酸亞鐵40克。溶于水后潑灑在食場周圍，面積控制在80-100，先潑藥后喂魚，每天一次，連用2~3天。用以防治原生動物性疾病。還有什么事項可以隨時來咨詢我們http://m.yiqijieneng.cn！

Disinfection of the food grounds can be carried out regularly during the epidemic season of fish diseases. Use 100 grams of copper sulfate and 40 grams of ferrous sulfate each time.
