硫酸铜可用于防治原生动物引起的鱼病（如：鞭毛虫、卵鞭虫病、隐鞭虫病、鱼波豆虫病、毛管虫病、斜管虫病、纤毛虫如车轮虫病等）以及甲壳动物引起的鱼病（如中华鳋病等）。

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.).

全池泼洒的用药浓度：常与硫酸亚铁配合使用，既安全又有效果。

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

春、秋季为0.7-1克/立方米，硫酸铜与硫酸亚铁比为5∶2或6:2，硫酸铜单用时在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.

夏季应降到0.6~0.8克/立方米。用药时间尽量全池均匀泼洒，用药后要做好解救鱼类浮头的准备工作。

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.

硫酸铜与高锰酸钾（5：2）合用，在10度以下水温时，浓度采用0.5-0.7克/立方米可治疗斜管虫病。

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.

硫酸铜与柠檬酸（3：2）合用，池水成0.15-0.20克/立方米可以治疗小瓜虫病。

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

硫酸铜0.7克/立方米，可治疗越冬亲虾的纤毛虫病。

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

硫酸铜0.7克/立方米和0.4克/立方米的扑草净合用，先用硫酸铜，后用扑草净与湿土（1：100）拌匀后泼洒可杀灭青泥苔。

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.

硫酸铜0.7克/立方米隔1天再用一次可杀灭轮虫和椎实螺；间隔12小时再用一次可杀灭田螺、湖螺以及对虾池赤潮生物（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).

硫酸铜1克/立方米，可杀灭水中轮虫，以预防因轮虫过度繁殖引起缺氧。

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

硫酸铜0.5克/立方米与1克/立方米大黄合用，可治疗细菌性疾病，隔3-4天再用一次可治疗草鱼出血病。

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、鱼(苗)种药浴。

2. Fish (fry) seed medicinal bath.

常用药浴浓度为8克/立方米的铜铁合剂水溶液（即硫酸铜与硫酸亚铁比为5∶2），硫酸铜8克/立方米加漂白粉10克/立方米合剂水溶液药浴10-30分钟。以上两种配方均可以杀灭体表和鳃上细菌、原虫，对未形成胞囊的粘胞子虫也有效。

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、杀灭藻类植物，控制有害藻类生长。

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

硫酸铜可以用来抑制、杀灭池塘过多的蓝藻和丝状绿藻，也可以杀灭真菌和某些细菌。硫酸铜用于杀灭蓝藻有效果，还可以用于防治微囊藻、卵甲藻引起的鱼类中毒。全池泼洒的用药浓度为0.7-0.9克/立方米（硫酸铜与硫酸亚铁比为5∶2），硫酸铜还可用于清除青泥苔、螺蚌等和防治丝状藻类附着引起的鱼虾蟹病。

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.

用药后要及时开动增氧机为宜，或在第二天清晨酌情加注清水。防止藻类死亡后，产生的有毒物质引起鱼类中毒或缺氧泛塘。

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、食场消毒。

4. Disinfection of tools and food facilities.

鱼具消毒用20克/立方米，硫酸铜水溶液浸泡半小时，可杀灭原虫。
