Grass carp fry why always die, how to prevent grass carp fry from dying

Water temperature is too low: Grass carp fry are sensitive to water temperature, if the water temperature is below 10 degrees, they have the risk of death. Poor water quality: poor water quality will lead to a large number of bacteria in the water reproduction, so that grass carp fry sick and dead. Anoxia in water: The oxygen content in water may be reduced for various reasons, so that the grass carp fry died due to lack of oxygen. Inadequate food: Although the grass carp fry appetite is not large, but long-term non-feeding may also lead to its death.

1. Why do grass carp fry always die

1. Water temperature is too low: Because grass carp fry is still relatively small, it is very sensitive to the surrounding environment. If the water temperature is too low, it may lead to the death of grass carp fry, because grass carp fry generally like to live in warm places. Specifically, if the water temperature is below 10 degrees, grass carp fry will be more dangerous.

2. Poor water quality: If the water quality is too poor, it may cause bacteria in the water to multiply faster, and the grass carp fry will easily get sick at this time. Disease is an important cause of the death of grass carp fry, and in some cases of infectious diseases, it may even lead to large-scale death of grass carp fry.

3. Anoxia in water: Grass carp fry also have relatively high requirements for the oxygen content in the surrounding water. If the oxygen content in the water is reduced due to low air pressure or other reasons, the grass carp fry may die due to lack of oxygen.

4. Insufficient food: The grass carp fry are small in size and have a small appetite. Even so, if they are not fed for a long time, they may die.

2. how to prevent the grass carp fry from dying

1. Ensure a good water environment: First of all, we must ensure that all factors of the water environment are suitable. The first is the water temperature, try to keep it around 20 degrees. Then the water quality, to change water regularly, basically a week or so have to change water once, but do not change too much water, otherwise the water environment will change dramatically. Then there is the oxygen content in the water, before breeding, we have to prepare oxygen pumps and other appliances, which can be used when necessary.

2. Provide sufficient food: When raising grass carp fry, it is necessary to provide sufficient food so that they will not die easily. Grass carp fry can eat nutritious food such as egg yolk, fish and insects, or artificial feed. If the length of grass carp fry reaches more than 5 centimeters, they can eat grass.

3. Disease prevention: Disease prevention is also an important task. Measures such as regular disinfection and regular monitoring of the status of grass carp fry can be taken to prevent diseases.
