High temperature Culture Technology of Sea Cucumber

Recently, there is a frequent phenomenon of heat death of sea cucumbers due to high temperature, which causes huge economic losses to farmers. Sea cucumbers will float and peel at high temperature, and continuous high temperature will lead to sea cucumber death. So how to raise sea cucumbers at high temperatures? Come to the pro-agriculture network to take a look at the culture techniques of sea cucumbers in the high temperature period.

1. Deepen the water level

High temperature makes sea cucumber death, we must find a way to lower the water temperature, through raising the water level, artificial shading and fertilizer water effect to reduce the water temperature, so that the sea cucumber in a relatively suitable temperature environment. Keeping a certain water level can effectively reduce the transmittance of the water body and prevent the water temperature from getting higher, but at the same time, it is necessary to prevent the lack of dissolved oxygen in the water body caused by high temperature and muggy heat.

2. Optimize water quality

With the high temperature, sea cucumber back to the reef, many farmers do not pay so much attention to the management of water quality, when the change of water quality of the breeding site has a certain impact on sea cucumbers, which is the key point for sea cucumbers to spend the summer safely. Proper supplement of bacteria and carbon can not only ensure the stability of the water body, but also accelerate the material circulation, cultivate beneficial microorganisms, and make the water body in a role of fertility.

3. Strengthen the management of bottom quality.

The phenomenon of black bottom and smelly bottom should be caused by feeding bait and forage at ordinary times. if it is not treated at high temperature, it will increase the risk of sea cucumber culture in the high temperature period. Therefore, the low culture pond must be cleaned regularly to improve the environment of the culture site and reduce the phenomenon of sea cucumber hypoxia and poisoning caused by bottom black bottom, smelly bottom and fermentation. In addition to improving the bottom environment at high temperature, it is also necessary to increase oxygen and detoxify. At high temperature, the water body is generally anoxic, and 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 spend the summer safely.

4. Strengthen the physique

At high temperature, it not only makes the culture environment unstable, but also has a certain stress response to sea cucumbers. Long-term stress reaction will lead to a rapid decline in the physique of sea cucumbers, which can not resist the high temperature and low heat environment for a long time. Therefore, it is necessary to activate the physique of sea cucumbers in time after rain or high temperature, so as to improve the physique of sea cucumbers and reduce the impact of high temperature on them.

The above are the high-temperature culture technology of sea cucumbers brought by the pro-agricultural network. At high temperatures, we must do a good job in the regulation of water temperature and the stability of the culture environment, which is the key point related to whether the sea cucumbers can safely spend the summer.
