What impact has the recent continuous high temperature weather brought to hairy crab culture?

The continuous high temperature weather has brought extremely adverse effects on the growth of hairy crabs. The sudden increase in the temperature of the lake resulted in the long-term low pH value in the lake, which led to the serious death of hairy crabs due to hypoxia.

Hairy crabs are a delicious food in autumn, and most people will choose to buy some hairy crabs to treat themselves in their lives. However, for hairy crabs under the influence of continuous high temperature weather, not only the taste is not good, but also the phenomenon of insufficient crab yolk is prone to occur, which has brought extremely adverse effects on hairy crab culture. Due to the recent high temperature, the pond water was exposed to the sun. Once the water temperature exceeds 35℃, hairy crabs stop eating. ?

The price of high-quality hairy crabs may rise this year.

Hairy crabs need to go through different stages. Generally speaking, it needs to go through five molts, and every time it molts, the crab will grow a circle. However, at high temperatures, crabs will eat less. Many crab farmers are worried that it is difficult for hairy crabs to shed their shells, and extreme high temperature will cause algae to float in the lake environment. Rich in nutrition? State, easy to affect the growth of aquatic plants, resulting in a shortage of food chain of hairy crabs. The continuous increase in temperature will also lead to the continuous increase in the price of high-quality hairy crabs, which will also have a certain economic impact on ordinary consumers.

With the continuous high temperature, the raising cost of crab farmers is getting higher and higher.

Under the continuous high temperature, the water body is prone to lack of oxygen, and the healthy growth of hairy crabs in water can only be guaranteed by increasing oxygen. They endure the heat, replenish oxygen to the lake at any time, and remove silt at the same time, or replace the silt at the bottom of the river to make the aquatic plants grow better.

In the process of breeding hairy crabs, it is necessary to observe the growth situation and facilities of hairy crabs, reasonably detect the water quality in the breeding area, and take certain measures in time after finding problems, so that hairy crabs can obtain a more reasonable growth environment. Generally speaking, the suitable temperature of hairy crabs is between 22℃ and 25℃, and hairy crab culture is more vulnerable to losses under continuous high temperature weather.
