After returning to the earth in spring, the temperature rises and everything recovers, and the number and virulent capacity of pathogenic microorganisms will continue to increase. (For example, the hemolytic value of the exudates of Aeromonas hydrophila is 23 at a water temperature of 12°C, and the lethality rate is 0; When the water temperature is 20°C, the hemolysis price rises to 68 and the fatality rate reaches 83.3%). During the spring, it is the top priority of the current work to do a good job in the “water quality, temperature difference, nutrition, and disease prevention†of turtle culture.
First, the water quality is related to "fishing the water to raise water first," and the principle of "broad water raising of big fish" is also applicable to turtle culture. The soft-shelled turtle is naturally happy and afraid of dirt. A good water environment is one of the basic conditions for the steady growth of soft-shelled turtles.
1. In the case of a relatively stable climate after the spring season, changing the water and sewage in the open-air overwintering pool and the greenhouse overwintering pool, appropriate replacement of part of the bottom water and adding some new water will reduce the total amount of waste and harmful bacteria in the culture pond. The role.
2. Water body disinfection Water is one of the main ways to spread diseases. Regular and timely disinfection of water bodies is an effective method to control the occurrence of turtle disease. During the spring, the soft-shelled turtle has a weak constitution and should use mild drugs. , such as iodine preparations, bromine preparations and so on.
3, the water quality regulation caused by the disease of the soft-shelled turtle pathogens are mostly pathogenic bacteria, generally difficult to survive in the partial alkaline environment, it should be regularly used quicklime to adjust the pH of the water, the pH value controlled between 7.5-8.0, during the spring, The use of quicklime should not be excessive.
Regular use of photosynthetic bacteria, EM bacteria and other microbial agents, on the one hand can inhibit the proliferation of harmful bacteria, on the other hand can break down the waste water, waste, etc. in the water, can effectively purify the water body; In addition, in the new pool ready to spill sprinkling microorganisms Formulations can lock well and stabilize water color.
The proper amount of stocking some water hyacinths and other aquatic plants can also effectively purify water bodies.
4. Controlling the color of water directly reflects the population and state of beneficial algae in the water. The color of the soft-shelled turtle pond should be kept in a green state, and the algae balance, and the water body will be stable.
In the new pond to be stocked, it is necessary to vigorously fertilize algae to create a suitable environment for the soft-shelled turtle pond and to adapt it quickly to the environment. "Fat Underwater Pond" is the reason.
Second, the temperature difference is related to “No Spring on the third dayâ€. During the spring, it is a season when the weather changes. Whether it is the precipitation of the open-air pool or the elevated water level of the Wenpen Pond, it can prevent high temperature and ventilation and change the wintering pool. Water discharge should be aware of the weather changes, depending on the specific circumstances, and should not be subject to large-scale irrigation.
The graded ponds during the beginning of spring should also be aware of the changes in temperature and water temperature, especially if the water temperature does not exceed 3°C.
If the temperature difference is too large, whether it is the original turtle pond, or the soft-shelled turtle, it is very likely to cause severe stress reactions, resulting in a large number of deaths.
Third, the nutrition temperature rises, the soft-shelled turtle's vitality increases, activities are frequent, physical fitness also increases. It is advisable to feed in a timely manner and increase the amount of bait appropriately, adding more energy-supplying substances and vitamins and some microbial preparations to the bait.
Turtles in open-air ponds should be fed with fish, snails, and animal livers in a timely manner to attract food. When the appetite is strong, the amount of compound feed should be increased, and multivitamins, microbial preparations, or antibiotics should be added.
In addition to the appropriate increase in feeding, the soft-shelled turtle should also be supplemented with some vitamins, antibiotics, immune agents, and liver and gall bladder herbs.
In short, the nutrient feeding during the beginning of spring is important for restoring, enhancing physical fitness, conditioning and improving internal organs.
Fourth, disease prevention during the opening of the spring, is a period of frequent occurrence of turtle disease, mainly cold, skin perforation syndrome, fungal disease, bleeding, etc., should take the same precautions and treatment, ecological prevention and drug prevention and treatment of the principle.
1. Disinfection of the environment inside and outside the culture ponds, water bodies, and the bottom of the pool should be regularly disinfected and changed at the end; disinfectants such as bleaching powder, quicklime, iodine preparations and bromine preparations should be used;
2, the fish body disinfection graded pond fish should be fully disinfected to prevent bacteria into the new pool, the use of drugs such as potassium permanganate, iodine preparations, salt and so on.
3. Reasonably stocking turtle ponds with reasonable stocking density. Do not blindly pursue high-density and high-yield production. Only reasonable density can provide benefits.
If the stocking density is too high, the phenomenon of mutual biting and fighting of the soft-shelled turtle will increase, and the probability of disease susceptibility will increase. Once the disease occurs, it will not be worth the loss.
4, "Five set" feeding timing, positioning, set quality, quantitative, set people to vote on the turtle feed, feeding amount to 80% full, an hour or so is appropriate. Too much feed will not only waste feed, but will also lead to deterioration of feed due to prolonged feeding. It will also increase the internal organs load of the soft-shelled turtle.
5. Regulate water quality The combination of water disinfection and water quality regulation makes the water color suitable, the algae balance, and the water stability.
6, drug prevention adhere to the "disease-free prevention, early treatment of disease," "a minor disease retreatment, serious illness and light governance," "outside of the combination of internal and external use" principle, to avoid "no disease regardless of illness and disorder rule" phenomenon.
7. Ecological prevention Vigorously promote the use of microbial preparations in water bodies and feedstuffs, and strive to grow a certain area of ​​aquatic plants in the water body and stock a certain number of carp species to purify the water body, and at the same time feed effective Chinese herbal medicines. Not only economic but also effective, but also in line with the trends and requirements of pollution-free farming.
