Prevention and treatment of "autumn plague" in fish

In autumn, fish are prone to acute diseases with high mortality, such as impotence, small claw, Gill rot, water mildew and so on, commonly known as "autumn plague". Seven key points should be taken to prevent and control the outbreak of "autumn plague" in fish.

1. Improve the ecological environment. Pay attention to ecological control, properly feed full-price concentrate, tender grass, etc., as far as possible to meet the nutritional needs of fish growth, in order to improve their immune ability.

2. Actively add new water. The addition of new water can not only bring oxygen and a variety of nutrients, but also dilute the organic matter and biological metabolic toxic substances in the pool water, which is conducive to disease prevention.

3. Pay attention to the improvement of water quality. Can apply quicklime, bleach, microbial preparation and so on.

4. Strengthen the killing of insects in fish. In vitro parasitic disease of fish is the inducing factor of many diseases, so we must strengthen observation to kill insects thoroughly and put an end to the harm of various complications.

5. Add bait properly. Microbiotics and allicin are regularly added to the fish feed to enhance the fish's ability to resist diseases.

6. Avoid stirring of carp. If there are more carp in the pond, concentrate should be added accordingly to make the active carp full and lazy, so as to avoid muddy the pond water.

7. Neutralize pH. In autumn, ponds are often acidic, but in an acidic environment, fish have slower metabolism, less food intake, poor digestion and weak disease resistance, so they should regularly apply appropriate amount of quicklime to neutralize acidity and alkalinity.
