Sea cucumbers die in the depths of the aquaculture network in May Now sea cucumbers are dying

The northern sea cucumber culture is mostly the open-air culture of the intertidal zone and shrimp pond reefs, and many farmers have the concept of low temperature in winter and sea cucumbers do not need to be managed, resulting in many sea cucumber diseases. From past experience, the time of onset of sea cucumber farming in a large area is basically the same, and most of them in Shandong are from mid-February to early May, concentrated in March-April.

During this period, the air temperature and water temperature gradually rise, but the recovery speed is not synchronized, the temperature rises quickly, and the water temperature rises with a lag. The air temperature is higher than the water temperature, so that the water temperature difference between the middle and lower layers of the pond is formed, forming a water temperature stratification (1-2 water temperature difference between 1 m and 3 m). At the same time, sea cucumbers consume a large amount of oxygen in their activities and metabolism at the bottom, causing the bottom layer to become a hypoxic area, or even an anaerobic area (the bottom dissolved oxygen is usually below 3mg L during this period).

In the hypoxic state, the metabolic level of sea cucumber decreases, the function of various systems is blocked, and the ability to resist stress and disease is greatly weakened. At this time, the bottom anaerobic bacteria multiply, and the organic matter is anaerobically decomposed, producing a large number of harmful substances such as ammonia nitrogen and hydrogen sulfide, which further aggravates the adverse effects on sea cucumbers. Due to the deterioration of water quality and weak physique, various pathogenic bacteria take advantage of the deficiency to enter, resulting in a large area of sea cucumber disease.

The senior team of sea cucumbers, the old Yin family, will answer for you, thank you.

If you have professional problems about sea cucumber farming, you can ask experts to visit the site and give detailed solutions, so that you can find out the problem and solve it as soon as possible. Qingdao sea cucumber Lao Yin's family is professional for the answer, I hope to help you, thank you.

Summary. This year's high temperature, heavy rain, sultry heat, aquatic weeds grow crazy and die and other reasons, resulting in the sea cucumber breeding industry once again returned to the pre-liberation period.

The main disaster of sea cucumber farming is in summer, when sea cucumbers are hibernating, and their resistance is very weak. When the water temperature exceeds 32, the probability of drifting, peeling, and falling off the reef is greatly increased.

What to throw in a sea cucumber circle will cause the sea cucumber to die.

This year's high temperature, heavy rain, sultry heat, aquatic weeds grow crazy and die and other reasons, resulting in the sea cucumber breeding industry once again returned to the pre-liberation period. The main disaster of sea cucumber farming is in the summer of Tanpin, when the sea cucumber is dormant in summer, and the resistance is very weak. When the water temperature exceeds 32, the probability of drifting, peeling, and falling off the reef is greatly improved.

I hope my reply is helpful to you and I wish you a happy life!

Recently, with the increase in water temperature, there is a phenomenon of sea cucumber poisoning and death in the circle, the place of occurrence: there are pits at the bottom of the pond or places where there are dead moss and rotten grass and jujubes, the symptoms are manifested: sea cucumbers gather and are accompanied by systemic decay, and after dissection, it is found that the intestines of sea cucumbers are full of foul-smelling black mud, and all sea cucumbers will definitely die if they enter these places.

The main reasons:1Where there are pits, it is easy to gather dirt (in winter, there are benches and shacks in the pits, and the sea cucumbers who die of frostbite are particularly serious). 2.Dead moss and rotten grass were not dealt with in time. 3.In spring, the management and maintenance of the bottom of the circle is weak.

Handling suggestions:1Strengthen the management awareness of the winter circle (e.g. reef remediation).

2.There are many dead moss and rotten grass in the circle to be fished out in time, especially the yellow tube vegetables, which rot very quickly after death. 3.

Use a circulating water pump to flush the bottom of the ring. 4.To change the bottom of the detoxification, follow the principle of a small number of times, and it is a good choice to cooperate with the bottom of the oxygenation treatment circle.

Note: The maintenance of the bottom of the circle in spring is of great significance, not only to provide a good environment for the growth of sea cucumbers in spring, but also to buy an insurance for sea cucumbers in summer.

1.Due to water quality problems, the feces and bacteria of sea cucumbers in the pond are eaten into the body of sea cucumbers along with food, causing intestinal diseases, reduced food intake, and even death.

2.Why do wild sea cucumbers grow fat, fast and good? Because they live in pristine ecosystems.

I am a farmer in Laizhou, Shandong, not a big household, there are always problems when I first raised, I lost a lot of money, what medicine has been used, what Neptune what Western medicine added antibiotics, the effect is average, cure this, that is sick again, the best in the long term is Chishen Chinese herbal medicine, auxiliary food delivery, restore the original ecology of water quality, long-term delivery, ammonia nitrogen and other components in the pool have been controlled, sea cucumber eating increases intestinal diseases will not appear again, of course, there are a small number of deaths, but for the increase in production, It's all drizzle.

Oh sea cucumber in the breeding problem species of water requirements are not very high, some people use the factory to raise treasure fish after the waste water to raise sea cucumber, the effect is also very good, do not feed, it grows very well and is not sick, during the breeding period of the main problem is in the intestines, can be mixed with some ** enteritis drugs mixed in the bait species feeding, how do you raise.

It's just a matter of saying the specifics, otherwise it's hard to explain, and there's so much to pay attention to.

The main causes of sea cucumber disease are stress and intestinal diseases. These can be done through prevention, the source of the disease to a minimum, can be used regular use of microecological disinfection, cast bacteria to balance the water quality of beneficial bacteria, add intestinal prebiotics in the material, add multi-dimensional supplement to the nutrition of sea cucumbers, enhance immunity, and achieve low-cost breeding.

Of course it will, as long as it's a living thing, it's going to get sick.

Recent cause of death:

First, after the rain, the sea water appears to be inverted, that is, the water suddenly becomes clear, or red, the semi-clumps turn bright and black, and the dominant turns yellow and green, and a large number of algae die, producing toxic and empty elements.

Second, the seawater was poisoned by a large amount of rainwater (fresh water) mixed with celery.

Third, after the rain, the rainwater floats on the surface, leaving only a layer of fresh water cover, who the oxygen in the air cannot melt into the lower layer of seawater, in addition, the freshwater cover is equivalent to the greenhouse membrane of the land buckle, it is the underground seawater heating, which aggravates the geothermal phenomenon, and then the bottom hypoxia is more serious, so the sea cucumbers will crawl out of the reef to the shore or the top of the reef due to the lack of oxygen, and the severe oil swelling will be spitting out of the intestines, and even worse, the skin will be optimized.

At this time, do not use ** peeling drugs should be used to detoxify and increase oxygenation to change the bottom and adjust water to reduce the onset of the disease If you use it to connect it, you may go home to the chrysanthemum skin phenomenon.

Recent cause of death:

One. After it rained.

The seawater appears to be inverted.

It's just that the water suddenly becomes clear.

or turn red. Semi-dark darkened.

The advantage turns yellow and green.

Phenomenon. A large number of algae died.

Toxin production. Second, seawater died of poisoning by mixing with a large amount of rainwater (fresh water).

Third. After the rain.

Rainwater drifts on the surface.

Only a layer of fresh water remains.

Who is in the air.

Oxygen. It does not melt into the lower seawater.

Other than that. Fresh water cover is equivalent to.

Land. buckle the greenhouse film.

It is the groundwater that warms up.

exacerbated geothermal phenomena.

And then the underlying hypoxia is more severe.

Therefore. Sea cucumbers will come from due to lack of oxygen.

Reef. Introverted.

Shore. Or climb out of the reef.

Severe liquid acres of oil edema mouth and vomiting intestines.

What's more. Improves skin appearance.

Do not use ** at this time.

Peeling. of medications.

Detoxification should be used to increase oxygen.

Bottom-up. Reducing the incidence of disease can be reduced by starting with water transfer.

If you want me to plug in.

may go home to brighten the year.

Chrysanthemum. Dermatosis occurs.
