With what pesticide poison fish can make the fish die out?

With the rapid development of science and technology, many pesticides have been developed and applied in all aspects. There are special herbicides for weeding and insecticides for insecticides, so what pesticides can be used to cure fish?

What kind of pesticide can be used to cure fish

Pesticide fish generally use rotenone, which is a concentrated component of rotenone. Rotenone is a ketone extracted from the root of aquatic plant fish rattan, which is generally used as a pesticide and is a relatively safe drug in agriculture, but when it acts on fish ponds, a small amount of rotenone can cause large area death of fish, so it should be used cautiously on the edge of fish ponds. The effect of using this substance in the fish pond is better when clearing the pond, and it can be killed together with small miscellaneous fish and parasites in the water, and the drug effect disappears in about 10 days.

In addition, it should be noted that do not use pesticide poisoned fish in wild news or public drinking water, it is easy to cause poisoning and endanger public security, and be prosecuted and punished for crimes against public security. According to the provisions of the law, whoever poisons or causes serious injury, death or heavy losses to public or private property by other dangerous means shall be sentenced to fixed-term imprisonment of not less than ten years, life imprisonment or death.

What is rotenone

Rotenone is essentially an insecticide found in the roots of Leguminosae plants in tropical and subtropical Asia, almost insoluble in water, but soluble in ethanol, acetone, carbon tetrachloride, chloroform, ether and many other organic solvents. The agricultural pests controlled by this pesticide are aphids, planthoppers, yellow striped beetles, moths, cabbage insects, and so on. this pesticide has strong specificity and kills insects quickly, but it is easy to decompose after its efficacy, and it is basically a pesticide that is harmless to the human body, but it should be noted that accidental administration will still lead to poisoning and damage to the liver and kidney.

Although many species of fish will quickly surface in the solution of lethal concentration of rotenone, if they are transferred to methylene salt solution with 5-lOmg concentration in time, the fish will recover immediately. With the application of this characteristic of rotenone, high quality ornamental fish can be caught, and this method can sometimes be used in some scientific research.

The above is about the use of pesticides for fish medicine some of the relevant knowledge, in the use of this pesticide for fish medicine, or to pay attention to their own protection to avoid pesticide poisoning.
