The high temperature in summer is very harmful to sea cucumbers, what are the problems that should b

Recently, heavy rainfall and continuous high temperature in Shandong, Dalian and other places have led to a wide range of sea cucumber deaths, and the sea cucumber breeding industry has suffered heavy losses. The summary is as follows: when the water temperature is continuously higher than 24, the feeding and activity of pond ginseng stop due to summer hibernation, the metabolic level is significantly reduced, and the emergency disease resistance ability is significantly weakened. At the same time, the decomposition and release of toxic substances at the bottom of the water lead to a sharp deterioration of water quality, resulting in hypoxia and pathogen breeding in the water body, making sea cucumbers very susceptible to diseases.

When the water temperature is consistently higher than 33, sea cucumbers cannot maintain basic life activities through summer hibernation, and only dies. The high temperature of the ginseng pond is mainly caused by the following two reasons: first, the high temperature in summer will directly cause the water temperature to rise; Second, the heavy rain caused the freshwater and seawater in the ginseng pond to stratify, and the bottom heat was difficult to dissipate, resulting in the continuous increase in the temperature of the bottom water.

In view of the above situation, the following measures can be taken:

The first is to maintain a deeper water level. With the continuous increase of water temperature, sea cucumber breeding ponds should try to maintain the highest water level under the existing conditions of the pond to ensure that the bottom water temperature is relatively low. In case of continuous high temperature weather, it is best to cover the ginseng pond with a shade net, frame it with iron wire, and fix the cement column, so that the water temperature can be reduced by about 3, on the one hand, it can better create the water temperature conditions for the normal feeding and growth of sea cucumbers, and promote the growth of sea cucumbers; On the other hand, it can avoid the harmful effect of continuous high temperature on sea cucumbers.

The second is to prevent the decay of seaweeds, weeds and other plants in the pond. If there is a large amount of seaweed and weeds in the breeding pond, it should be found and removed in time to prevent it from rotting in the pond at high temperatures, resulting in water quality deterioration.

The third is to control the plankton in the pond. The conditions of light and water temperature during the high temperature period in summer are suitable for the growth of plankton. The proliferation of plankton such as green algae, dinoflagellates, and flagellates can easily affect the water quality and adversely affect the growth of sea cucumbers.

Fourth, increase oxygen in a timely manner to control water quality. The dissolved oxygen saturation of seawater decreases during the high temperature period, and the lack of oxygen in the pond is easy. The amount of dissolved oxygen in the pond can be increased by changing a large amount of water more than 1 3 each time or using an aerator to ensure the normal living environment of cultivated sea cucumbers.

Fifth, scientific water exchange. During heavy rainstorms, no water is allowed to enter or drain; After the rainstorm, the inflow and drainage must be measured before the salinity of the outer sea water is above 22 before the water can be entered; The water intake should be carried out in the second half of the night and early in the morning to reduce the temperature of the pool water and increase the amount of water exchange, which can continuously reduce the water temperature. If the conditions are good, the high-level pool or deep saline water well can be used for water exchange, and the cooling effect is obvious.

Sixth, strengthen daily management. Insist on patrolling the pond every morning and evening, observe the changes in water color, water level and transparency, regularly (3 5 days) dive into the bottom of the water to check the sea cucumber, observe whether there are abnormal changes in body color and body shape, make a good record, and even if the ginseng is found to avoid affecting the water quality.

It is necessary to pay attention to oxygen, but also to the cleanliness of the water source, to pay attention to the filtration of the water source, to pay attention to the air, and also to pay attention to the oxygen content of the water source.

Sea cucumber belongs to the temperate and cold zone species, high temperature will cause sea cucumber to get sick and die, to control the water temperature, change the water frequently, and often remove the debris at the bottom of the water.

Sea cucumber is a well-known tonic in our country and is deeply loved by the general public. However, sea cucumber belongs to the cold temperate zone, and the suitable temperature for growth is 3 18, and the optimal water temperature for survival is 10 16. The change of water temperature will have a significant impact on the growth and physiological activities of sea cucumbers.

Once there is extreme heat in summer, the water temperature will be affected and rise, resulting in a series of stress reactions of sea cucumbers, such as vomiting dirt and melting skin. When the temperature exceeds the heat resistance limit, it will cause heat death to sea cucumbers.

It will seriously affect the metabolism of sea cucumbers and inhibit their growth, so if you want to prevent it, try to choose new varieties that are resistant to high temperatures and grow fast.

Throw the intestines out to confuse the enemy into giving them to eat, then run away that can be regenerated,

It's like throwing the intestines out and running away.

Summary. The most suitable salinity for the growth of sea cucumber is 27-30, the salinity that can survive is not more than 39, not less than 14, the change of salinity has a great impact on sea cucumber, and the salinity is often unstable in daily management, such as when the summer rain is very heavy, at this time, the salinity of the open sea must be measured before changing the water, if the difference is less than 2, it can be changed, if there are more than 2, the water should be changed as little as possible, otherwise the sea cucumber is very prone to vomiting.

When the temperature of the sea cucumber exceeds 34, the sea cucumber will appear, that is, the sea cucumber will die. The most suitable temperature source for the growth of sea cucumbers is 10-18 degrees, higher than about 24 degrees to start summer hibernation, lower than 5 degrees to start hibernation. The water temperature of the pond is generally relatively stable, and the cooling and heating are not very affected, but when the weather changes drastically, the water must be measured when the temperature is different.

The most suitable salinity for the growth of sea cucumber is 27-30, the salinity that can survive is not more than 39, not less than 14, the change of salinity has a great impact on sea cucumber, and in the daily management will often encounter the situation of unstable salinity, such as when the summer rain is very heavy, at this time the salinity of the open sea must be measured before changing the water, if the difference is less than 2, you can change the macro change, if there are more than 2 of the forest silver then try to change the water, otherwise the sea cucumber is very easy to vomit.

When the temperature of the sea cucumber exceeds 34, the sea cucumber will appear, that is, the sea cucumber will die. The most suitable temperature for sea cucumber growth is 10-18 degrees, with summer hibernation starting above 24 degrees Celsius and hibernation starting below 5 degrees. The water temperature of the sea cucumber pond is generally relatively stable, and the cooling and heating are not very affected, but when the weather changes rapidly, it is necessary to measure the difference in temperature.

The most suitable salinity for the growth of sea cucumber is 27-30, the salinity that can survive is not more than 39, not less than 14, the change of salinity has a great impact on sea cucumber, and the salinity is often unstable in daily management, such as when the summer rain is very heavy, at this time, the salinity of the open sea must be measured before changing the water, if the difference is less than 2, it can be changed, if there are more than 2, the water should be changed as little as possible, otherwise the sea cucumber is very prone to vomiting.

Summary. 1. Pay attention to water quality and bait, change water and bait in time. 2. If conditions permit, you can test the water quality, and then see if there is a deviation in the bait ratio and deal with it in time.

3. It is important to observe whether the sea cucumber has a disease, and to treat it in time if it is sick. When the water temperature reaches 20, the cucumber will move to the crevices of the reef in the deep sea or hide at the bottom of the rocks, and the whole body will shrink and harden like a thorn ball. Animals don't eat it.

It sleeps for the summer, and only wakes up after the fall to resume its activities.

1. Pay attention to the water quality and bait, change the water in time, and replace the bait to destroy the macro material. 2. If conditions permit, you can return the water quality test to see if there is a deviation in the bait ratio and deal with it in time. 3. It is important to observe whether the sea cucumber has a disease, and to treat it in time if it is sick.

When the water temperature reaches 20, the cucumber will move to the crevices of the reef in the deep sea or hide at the bottom of the rock, do not eat or move, and the whole body shrinks and hardens like a thorn ball. Animals don't eat it. It sleeps for the summer, and only wakes up after the fall to resume its activities.

See if the water temperature is too high over there.

Sea cucumbers are sensitive to temperature.

The water temperature is low, as long as it does not fall below 7 degrees, it will not have a big effect.
