Factory-scale farming of turtles

1. Greenhouse farming environment

The factory scale of the armored fish, the construction of the pool mostly uses reinforced concrete structure, design and construction of the hierarchy must take into account the illumination angle, temperature control and reasonable operation, but also consider the long-term and variability, in order to facilitate the regulation of water temperature between the upper and lower layers, More than 2 layers are good, and the single layer double column is ideal. The advantages of this turtle pond are that it has good light transmission, low cost, low breeding disease, high survival rate, and can be used all year round. Once it is converted, it is easy to dismantle.

The turtle pond lighting is used to increase the indoor temperature by using light energy, and to adjust the water quality through the light source to reduce the disease and improve the survival rate. Practice has proved that, in the same way, it is raised in two greenhouses which are opaque and opaque and light-transmissive and light-transmissive. The growth rate is similar, but the light transmission is stronger than the opaque and the survival rate is high, which not only reduces the culture. The cost also improves the quality of the turtle. Especially for a well-designed lighting greenhouse, the investment is less than half of the completely closed greenhouse, and the management is convenient and easy to operate.

The water quality should be checked regularly, and the water quality should be kept as stable as possible. When changing water, the speed is fast and the time is short. The factory-scale large-scale aquaculture water injection and displacement are very large. In order to meet the water injection at any time, a temperature-regulating storage tank that can ensure the full-load water consumption should be set up to ensure the smooth flow of the drainage system.

2. Scientific stocking seed

The culture ponds should be carefully sanitized, and the stocking density can be determined according to the different farming methods and specifications: the turtles are directly cultivated into the turtles, the average density is 15 per square meter, and the pre-stocking density is 30 per square meter; It is cultivated into soft-shelled turtles, with an average of 25 per square meter. The pre-stocking density is 50 per square meter. From the turtle breeding to the turtle, the intensive cement pool is 5 per square meter. If the mud pond is intensively, it is 1 per square meter.

You can also use the "gold iodine" 30 ~ 50 international units for short-term immersion into the pool. Do not clear the underwater pond before stocking. The environment and pond disinfection in the general factory controlled greenhouse can be dried first to make the bottom of the pool dry, and then before stocking. 10 days with 400-500 times of strong chlorpheniramine directly spray disinfection. If the outdoor pond is a cement intensive pond, it can be disinfected with strong hydantoin and water for 10 days before stocking. If it is an outdoor soil pool, the water at the bottom of the pool can be drained first, and then 20 to 30 kilograms of quicklime per hectare plus sodium humate (black soil) 15 to 20 kilograms, exposed to dryness in the sun.

If you are a turtle, you can walk it on the surface of the turtle. If you are not eating the turtle, you can use it directly in the pool. Seedling stocking must be a fertilizer pond, the advantage is that there is a certain degree of fatness and green water quality, so that the seedlings will have a sense of security after the pond, especially in the fertilizer water, there are a certain number of plankton for the seed to swallow. It promotes growth, while cultivating a certain amount of biomass plays a positive role in controlling the number of pathogenic microorganisms.

3, feeding management skills

The quality of the feed should be reasonably proportioned according to the nutritional needs of the different growth stages of the turtle, and it is required to never feed the spoiled spoilage. In the reasonable ratio of feed at each stage, the feed ingredients should also be appropriately adjusted according to the situation at the time. In the season when turtle disease is prone to outbreak, fresh disease should be added with some anti-disease and anti-disease "Enteritis Flat", "Qingre San", "Strong", and cooperate with water disinfection "Powerful Haiin", "Bromoammonium", " Gold iodine, "new chlorhexidine", "stry-killing" and viral blockers to increase the body's disease resistance.

In addition to the outdoor intensive pond table, the fixed water level is fixed from the beginning of the stocking, the indoor pool should be adjusted according to the size of the turtle. For example, when the water level of the turtle fry is 20 cm, the food table is parallel with the water level at 20 cm. When the turtle seedling grows to 50 g, the water level should be increased by 30-40 cm, and the food table should be adjusted accordingly and washed frequently.

According to different seasons and turtle specifications, the feeding time and frequency are adjusted. The turtle breeding stage is 3 times a day, that is, the first morning at 6 o'clock, the second at 1 o'clock, and the third at 7 o'clock. Timing should consider both the feeding time of the turtle and the digestion and absorption time of the feed in the turtle. The distance between meals and meals should not be too long or too short. Feeding at a fixed table or food court, so that you can grasp the eating situation, but also understand the growth of the turtle, but also easy to clean and disinfect. The feeding amount should be flexibly adjusted according to the actual eating situation on the basis of the previous meal, and the general adjustment range is about 5%.

4, strengthen disease prevention and control

Water mold is caused by fungi such as water mold and mildew, and is often found in freshwater fish. The fungus lurks in the water body all the year round, and finds the opportunity to attack the turtle. Once invaded, the bacteria will absorb the nutrients and start to grow. The turtle can be covered in a few days, causing the turtle to move slowly, lose appetite, and die until it is weak. At the beginning of the disease, the mycelium is still growing, so no abnormalities can be seen. As the mycelium grows, the surface of the turtle appears as a gray-white cotton-like hyphae, which is flocculent when viewed in water and densely layered.

Prevent the growth of germs due to water pollution, and disinfect molds regularly. Vitamin E can be added to the feed to increase the anti-fungal ability of the turtle. After the disease is found, the turtle can be cured by placing it in a diluted salt water or baking soda solution for 12 hours.

Red neck disease is also called big neck disease, caused by Aeromonas hydrophila. Like water mold, Aeromonas hydrophila breeds in water, causing disease by invading turtle body by various factors. The soft-shelled turtles are less sensitive to the outside world, their appetite is weakened, and their movements are slow. They are lurking in the shade, and many of them end up in the sun. When the turtle is sick, the neck is red and swollen and congested. Some turtles also have systemic edema, red spots on the abdomen, and the lesions gradually spread to ulceration.

The disease usually occurs in the hot season, and should be based on prevention. The turtles are fed several times a week to feed the turtles, and then disinfect the water before and after the rainstorm to avoid the disease. When the turtle is inoculated, it should be disinfected and replaced with water in time. Then it can be mixed with the heat in the feed. After three days, it can be inhibited or treated well.

The rot disease is caused by the invasion of the bacteria, mainly through the turtles biting each other or other causes of wounds invading the body surface. The incidence rate is high and the epidemic time is long. When the disease occurs, the skin of the body surface begins to become inflamed and swollen, and the diseased tissue begins to gradually become necrotic and discoloration, followed by ulceration. As the disease spreads, the area of ​​ulceration is getting bigger and bigger. In severe cases, the muscles and bones are exposed, the limbs are rotten, and the claws fall off, which is extremely harmful.

When the turtles enter the pool, they should choose healthy, wound-free seeds. The water should be kept clean, disinfected regularly, and vitamin E added to the feed to increase disease resistance. When the disease occurs, the pool water is drained, and then the turtle is completely removed. The lime pond is used to disinfect the pond. After exposure, the water is discharged into the pond. The turtle is dipped in diluted potassium permanganate solution and then coated with bleaching powder for several days. It will heal.
