What impact has the recent sustained high temperature weather had on hairy crab farming?

Sustained high temperature weather has had an extremely negative impact on the growth of hairy crabs. The surface temperature of the lake water has suddenly increased, causing the pH value in the lake water to remain in a low condition for a long time, causing the hairy crabs to become severely hypoxic and die. die.

Hairy crabs are a delicacy in autumn. Most people will choose to buy some hairy crabs to treat themselves in life. However, for hairy crabs under the influence of continuous high temperature weather, not only the taste is not good, but also easy to eat. The lack of crab roe has had an extremely negative impact on hairy crab farming. Due to the continuous high temperatures recently, the pond water has been exposed to the sun. Once the water temperature exceeds 35°C, the hairy crabs will start to stop eating. ?

The price of high-quality hairy crabs is likely to rise this year.

The growth of hairy crabs needs to go through different stages. Generally speaking, it needs to go through 5 times of shedding. Each time the crabs shed their shells, they will grow a circle. However, under high temperatures, the crabs eat less and many crabs eat less. Farmers are worried that hairy crabs will have difficulty shedding their shells, and extreme high temperatures will cause a "eutrophic" state of floating algae in the lake environment, which will easily affect the growth of aquatic plants and cause a shortage of hairy crabs in the food chain. The continued rise in temperature will also cause the price of high-quality hairy crabs to continue to rise, which will also have a certain economic impact on ordinary consumers.

With continued high temperatures, the cost of raising crabs is getting higher and higher.

Under continuous high temperatures, hypoxia is likely to occur in the water, so the only way to ensure the healthy growth of hairy crabs in the water is through oxygenation. They endure the high temperatures and heat, adding oxygen to the lake at any time, and at the same time removing silt or replacing the silt on the river bottom so that aquatic plants can grow better.

In the process of raising hairy crabs, you must observe the growth and facilities of the hairy crabs, properly test the water quality of the breeding area, and take certain measures in a timely manner after problems are discovered, so that the hairy crabs can obtain A more reasonable growth environment. Generally speaking, the suitable temperature for hairy crabs is between 22°C and 25°C. Hairy crab breeding is more likely to suffer losses in sustained high temperature weather.
