CATDOLL : CATDOLL: What is the approximate survival rate of silver carp through artificial breeding?

First of all, we have to look at the weather and water temperature: I personally think that the critical water temperature for silver carp is 16 degrees Celsius. Below 16 degrees Celsius, bighead carp and bighead carp are in danger of death. The water temperature is between 16 and 18 degrees Celsius, and they are in danger of death. Even if they are lucky enough to survive, they grow very slowly, and then they will become thin and die due to lack of food. The final survival rate is generally not high, and it is not recommended to rush for success. There are two ways to release fry: winter and spring. Winter release means that after the fish pond is fished, the original fish pond is cleaned, repaired and detoxified. After a period of time, the temperature is colder and the fry have entered a fasting period. Released fry can survive the winter safely. The other way is to start releasing fry in March after the spring.

Silver carp grows faster than bighead carp. In natural rivers and lakes, individuals weighing more than 10 kilograms can be seen. It is suitable for breeding in fertile ponds. The time for releasing fish fry should be planned. The time period for releasing silver carp can be selected in April and October. These two seasons are most helpful for the early growth of silver carp. The number of silver carp released each time should be gradually reduced, and the male-female ratio of the prepared fish should be controlled. The number of silver carp released per acre can be controlled at about 1,000.

Silver carp mainly refers to freshwater bighead carp and silver carp (also called flower carp). Almost all silver carp mainly filter feed on ephemera, among which silver carp mainly filter feed on algae and other ephemera, and its gill rakers are relatively dense; silver carp mainly filter feed on ephemera or gnats, and its gill rakers are relatively loose. There are no wild fish for sale in the market now, and if there are, they are some lies. I am telling the truth. In our rural areas, whether it is a large reservoir area or a collective pond, they are all contracted by someone. From large reservoirs to small ponds, fish are raised. The water is turbid and black, mainly because of the long-term water quality corruption caused by the feeding of flavored feed.

It is really difficult to judge whether silver carp and carp are artificially farmed or wild. For example, those raised in fish ponds without feeding are considered wild or farmed. There are currently very few silver carp and carp in rivers and they are basically not sold in general vegetable markets.

The survival rate of silver carp through artificial breeding is about 80%, which is still considerable. As long as the breeding is done well, the mortality rate will not be high.

If the artificial breeding method is correct and the breeding environment is suitable, the survival rate is about 70%.

It is relatively easy to raise, and the survival rate is about 90%. However, the density must be controlled well, and some nutritious feed must be fed.

There should be a probability of about 80% in the future. Generally, in an artificial breeding environment, a more favorable environment will be created, making it easier to grow.
