How to mix fishery medicine
With the increase of species and stocking density in ponds, the chances of simultaneous occurrence of different diseases of different fish in ponds are greatly increased. In general, the effect of single use of fishery medicine is not good, but the method of mixed use of fishery medicine can be used.
In order to significantly improve the curative effect.
1. The principle of mixing. It does not affect the chemical stability of the active components of the drug; does not increase the toxicity, the ideal effect is not to increase the toxicity; the efficacy is reasonable, the advantages are complementary; do not increase the cost of drug use.
2. Points for attention. (1) when mixed with fishery drugs, they should be tested in small water bodies or test equipment first. (2) for current use, drugs that need to be diluted or dissolved should be diluted or dissolved separately and then mixed. (3) the reasonable choice should be made according to the acidity and basicity of fishery medicine. (4) the types and times of mixed drugs should be reduced as far as possible so as not to increase the cost and pollute the water body.
3. Examples of mixed methods. The main results are as follows: (1) the mixture of copper sulfate and ferrous sulfate in the proportion of 5 ∶ 2 and sprinkling in the whole pool with the concentration of 0.7ppm can control some protoparasitic fish diseases. As an auxiliary drug, ferrous sulfate has a convergent effect, mainly to remove obstacles for copper sulfate to kill parasites. (2) every kilogram of rhubarb plus 20 kilograms of 0.3% ammonia is mixed and soaked for 12 hours, diluted with water and sprinkled throughout the pond, which can prevent and cure diseases such as viral hemorrhagic disease, bacterial Gill rot, white head and mouth disease of fish. Among them, ammonia is a synergist, which can improve the efficacy of rhubarb.
4. Fishery medicine that can not be mixed. (1) avoid mixing with quicklime when using bleach for disinfection, as hypochlorite and its ions are 50% less active in strong alkaline solutions than in neutral or slightly acidic solutions. (2) Alkaline drugs shall not be added when using trichlorfon to prevent the formation of more toxic dichlorvos, so as to avoid poisoning of humans, animals and fish.

The nutrition of making wine from fish is especially high.
People who drink alcohol all know that fish is the delicacy of wine, but few people know that fish itself can also make wine, and its nutritional value is several times higher than that of ordinary wine. In China's wine market, fish wine produced in Dalian has attracted people's attention. The people of Dalian not only love seafood, but also are good at studying the new "eating method" of seafood. It can be called one of the most unique fish wine in China. Sun Keman, a native of Dalian, has studied it painstakingly. The evaluation of the authority of the wine industry on fish wine is that it has changed the traditional technology of wine-making in China for thousands of years and created the world wine industry.
