1, clean water quality: small grass carp fry because of the age is relatively small, so the surrounding water quality is also more sensitive. If the water quality is very dirty, it will lead to bacterial infection of small grass carp fry, which may lead to their death. Therefore, in order to survive, they need to ensure water quality. As the case may be, a week or so for each water, do not let the water quality changes too much, you can replace about one third.
2. Appropriate water temperature: Too low water temperature is also an important cause of the death of small grass carp fry. They all like to live in warm water. Therefore, if conditions permit, it can be maintained at about 20 degrees, and no lower than 10 degrees.
3. Appropriate oxygenation: too low oxygen content in the water may also lead to the death of small grass carp fry. Therefore, when raising small grass carp fry, if the air pressure is relatively low and the oxygen in the water is too little, some oxygen can be supplemented appropriately.
4. Disease prevention: Because the resistance of the grass carp fry is not particularly good, it is easy to get sick and die at this time. Therefore, we must prevent diseases through disinfection and other measures, so that they are not easy to die.
1, adequate food: To small grass carp fry grow fast, you have to provide adequate and nutritious food. At this time, you can feed egg yolk and fish worms, which contain more protein.
2. Sufficient space: Providing sufficient space for the fry of grass carp is also an important aspect of promoting their rapid growth. Although the size of small grass carp fry is not particularly large, the number of fish should not be too large, not too dense.
3. Suitable water environment: Keeping the water environment suitable can promote the rapid growth of young fish. For example, the water temperature can be around 20 degrees; For example, in order to ensure that the oxygen content in the water is sufficient, oxygen can be used properly.
