[First-line Case] How Can Sea Cucumber Spend Summer Safely under High Temperature?
With the increase of temperature, sea cucumber culture has entered a critical period. Spending the summer safely is a problem that breeding friends are very concerned about in the process of sea cucumber pond breeding. Therefore, we must do a good job in the relevant work of safe summer from the following aspects.
1. processing moss
Before entering the high temperature, the moss in the pond must be cleaned to refuse hidden dangers. "Live moss is terrible, dead moss is even more terrible". Dead moss rots at the bottom of the pool, increasing the burden on the bottom of the pool. It will not only smother the bottom of the black pool, but also lead to bottom heat poisoning. Therefore, if there is rotten moss residue at the bottom of the pool, use it.Strong decomposition bottom modificationTimely decomposition.
2. water quality control
Before the high temperature, the water quality of the pond must be adjusted to maintain a good water color, stable algae phase and appropriate transparency, especially red water, black water, thick green water and other phenomena must be dealt with in advance. Recently, with the increase of water temperature, many ponds have flagellated algae, which should be used after changing water properly.Water Change Overlord+Strong decomposition bottom modificationTo provide a good growth environment for sea cucumber.
3. bottom quality management
June is a "bottom-raising" stage. Too much organic matter at the bottom of the pool should be cleaned to control the reproduction of harmful bacteria. Excessive organic matter at the bottom of the pool is fermented by bacteria at the bottom of the pool, which directly leads to thermal hypoxia at the bottom. Now there is a misconception among breeding friends that it must be good to see yellow sand with naked eyes on behalf of the bottom of the pool, but because bacteria and organic matter are invisible, it is too late to deal with it when the bottom of the pool is black.Weedley.It is a star product in sea cucumber culture that integrates bacteriostasis, bottom modification and oxygen enhancement.
4. adjustment water level
Appropriate to raise the water level, conditional up to 1.8 meters or more. There are many benefits of raising the water level: 1. A higher water level can effectively prevent the rapid rise of the pond water temperature;
2. When the water color transparency is certain, the higher water temperature can reduce the light transmittance of the water body and inhibit the growth of moss to a certain extent.
At the same time, it should be noted that in ponds with high water level, the aerator must be turned on in sweltering and windless weather and used in advance.The bottom is changed to white and black.Prevention of hypoxia; timely discharge of fresh water after rain, usedetoxification 360Break the stratification of water body and avoid anoxia at the bottom of the pool.
5. physical cooling
At present, the more practical methods are to build shading nets and drill wells to divert water. Both methods can effectively reduce the water temperature of the pond, but each has its advantages and disadvantages.
① Shading net: Shading net can reduce the light intensity of the pond, and also cause the oxygen-producing ability of algae to weaken. With the decrease of light intensity, most of the benthic light-happy algae may age and die, and then cause the decrease of dissolved oxygen. The death of some algae will also release algal toxins, which has a non-negligible impact on sea cucumbers. Secondly, it may destroy the original balance of bacteria and algae in the pond, reduce beneficial bacteria and increase harmful bacteria, it causes the rise of nitrite in the pond, and the imbalance of the proportion of carbon, nitrogen and phosphorus. Therefore, we must use it regularly in time.Strong decomposition bottom modificationorWeedley.Change the bottom, decompose the dead algae organic matter at the bottom of the tank, and sterilize and disinfect.
② Drilling a well to divert water, although it will reduce the temperature of the pond water, but the salinity of the well water is low and the heavy metal ions are high, so it must be used regularly after adding the well waterdetoxification 360orBaidu Quick SolutionComplex heavy metal ions; In addition, the well water is lack of nutrition and trace elements and essential nutrients, resulting in low immunity of sea cucumbers. Therefore, some ponds will have long-term well water supply in summer, resulting in sea cucumbers not only coming out late in autumn, but also having poor vitality. Therefore, sea cucumbers should be supplemented frequently after well water supply.stress nutrientsIncreased immunity.
