Key Technical Points and Management Methods for High-Temperature Sea Cucumber Farming
Recently, sea cucumbers have frequently been dying from heat stress caused by high temperatures, causing huge economic losses to farmers. Under high temperatures, sea cucumbers show floating and skin-melting phenomena, and continuous long-term high temperatures can lead to death. So how should sea cucumbers be farmed during high temperatures? Come to Qinnong Net to learn about sea cucumber farming techniques during the high-temperature period.
1. Deepen the water level
Since high temperatures kill sea cucumbers, we must find ways to lower the water temperature by raising the water level, using artificial shading and applying the fertilizer-water effect to reduce the water temperature, so that the sea cucumbers are kept in a relatively suitable temperature environment. Maintaining a certain water level can effectively reduce water transparency and prevent the water temperature from rising, but at the same time it is necessary to prevent insufficient dissolved oxygen in the water caused by hot, stuffy conditions.
2. Optimize water quality
As high temperatures cause sea cucumbers to retreat into the reef, many farmers no longer pay as much attention to water quality management. Changes in the water quality of the farming site have a certain impact on sea cucumbers, and this is a key point for helping sea cucumbers safely pass the summer. Proper supplementation of bacteria and carbon can ensure the stability of the water body, accelerate material circulation and cultivate beneficial microorganisms, giving the water body a fertilizing effect.
3. Strengthen substrate management
Normally, feeding bait and grass leads to black bottom and foul bottom phenomena in the pond. If these are not dealt with during high temperatures, they will increase the farming risk for sea cucumbers during the high-temperature period. Therefore, the bottom of the farming pond must be cleaned regularly to improve the farming site environment and reduce the oxygen deficiency and poisoning of sea cucumbers caused by black bottom, foul bottom and fermentation at the bottom. During high temperatures, in addition to improving the bottom environment, it is also necessary to increase oxygen and detoxify. Water bodies are generally short of oxygen during high temperatures. Supplying dissolved oxygen to the water body can not only maintain sufficient dissolved oxygen at the bottom, but also effectively remove toxic and harmful substances such as ammonia nitrogen and hydrogen sulfide, so that sea cucumbers can safely pass the summer.
4. Strengthen the physique
High temperatures not only make the farming environment unstable, but also cause a certain stress response in sea cucumbers. Long-term stress response will cause the physique of sea cucumbers to decline rapidly, making them unable to resist long periods of high temperature and low-heat conditions. Therefore, after rain or high temperatures, the physique of sea cucumbers should be activated in a timely manner to improve their physique and reduce the impact of high temperatures on them.
The above is the high-temperature sea cucumber farming technique brought to you by Qinnong Net. During high temperatures, it is essential to do a good job in water temperature regulation and the stability of the farming environment. This is the key point that determines whether sea cucumbers can safely pass the summer. If you want to learn more, please stay tuned to Qinnong Net.
