What is the appropriate water temperature for raising carp?

Carp can survive in water of 5-30 ℃, but the most suitable temperature for survival is 21-27 ℃, and the most suitable water temperature for embryonic development of carp is 20-30 ℃. If the water temperature changes too much, it will cause carp to get sick or die. When the water level is below 2 ℃, the carp will go into hibernation.

In general, carp live in the water temperature of 5-30 ℃, and the temperature of 21-27 ℃ is the most suitable. The sharp change of water temperature will bring some shadow to the growth of carp. When the water temperature rises or decreases by more than 3 ℃, the carp will get sick, and if the temperature changes by more than 10 ℃, it will lead to fish death.

According to the results of the experiment, the most suitable temperature for the embryonic development of common carp is 20 Mel 30 ℃. When the water temperature is 20 ℃ ~ 25 ℃, the appetite is so strong that you can eat continuously from morning till night. When the water temperature is below 10 ℃, the amount of activity will become very small, almost will not eat, when less than 2 ℃, will hide in the deep water will not eat motionless hibernation.

What kind of water is suitable for carp culture?

The adaptability of carp is very strong. Carp can be seen in rice fields with low water, closed ponds, gurgling streams and endless rivers. In some abandoned ponds or wild lakes, some carp can survive and grow well without feeding in time. Thus it can be seen that carp do not have high requirements for water quality, as long as there is water, even wild lakes and barren ponds can survive.

Matters needing attention in culturing carp

1. Preparation work. Tidy up the pond before stocking. The area of the pond is more than 2 mu, the water depth is 2-3m, the water retention is good, there is no leakage point, it is convenient for injection and drainage, and it is close to the water source. The bottom of the pool should be flat, the silt should not be too thick, and it should not exceed the 20cm.

2. Feeding management. Fish fry will grow very fast in the first few days after entering the pond, so it is necessary to increase feed. At present, there is a special carp feed on the market, feeding this feed can improve the survival rate and enhance the physique of carp, and grow very fast, relatively fat.

In the process of breeding, we should carefully observe the water quality and fry situation in the fish ponds, change the water frequently, and disinfect the fresh water and fertilize the water. If the water quality turns yellow and the transparency is too high, fertilizing water should be carried out immediately.

When the growth rate of fish is the fastest in summer, in order to ensure the nutrition of fish, more feed is needed, and it must be fed on time, according to position, and according to quantity.

3. Treatment of epidemic disease. When breeding carp, it is necessary to check every day for abnormalities, activity, feeding and growth of carps. If there is a lack of vitality, less food intake, slow swimming and other conditions, must be checked clearly, whether sick, timely isolation treatment, if there is a fish death, must be caught in time for disposal. To avoid large-scale infectious diseases or other fish diseases.
