(1) Hidden Turtle Pool: The hatchery pool generally requires a cement masonry structure, which can be built indoors or outdoors, with an area of ​​3-15 square meters. The pool depth should be used in consideration of other production purposes besides being used for hatchling turtles. There should be some land on one side or one side of the pool so that the hatchlings can rest ashore. The food table is located at the junction of water and land. The pool should be well equipped with drainage and drainage systems. Conditions can also be placed on the pool cover barbed wire to shade heatstroke, anti-snake, birds, rats and other predators.
(2) Baby Turtle Pond: The turtle pond should be considered for warm culture. In order to facilitate the erection of greenhouses and feeding management, generally 50-80 square meters. The pool is rectangular and has a cement and masonry structure. The height of the pool wall is 1.2-1.3 meters. The depth of the pool can be determined according to the individual size of the raised turtle. The pool should be equipped with a feed table and a large area of ​​rest basking table to prevent the turtle from being drowned when it cannot find a rest place. Intake and drainage systems and heating equipment to support.
2. Feeding of young and young turtles
(1) Feeding of juvenile turtles: hatchling hatchlings are relatively delicate and should not be directly under the pool. They can be allowed to crawl freely on the fine sand. After the umbilical cord dry off and converge, the body becomes flat from curly to flat. Place it in a pot, pot, and raise it. The first and second days of juvenile tortoises have not been absorbed because of the yolk and do not require external nutrition. Two days later, they began to feed leeches and cooked egg yolks, and they were fed several times a day. Each time they ate for the next time they were saturated, there was no surplus. After two days, they began to feed minced fish, shrimps, snails, and oysters. And mixed with a small amount of rice, wheat flour and other mixed feed. Change water daily to keep the basin clean.
After a few days of indoor rearing, they can be transferred to hatchlings for feeding. Before entering the pool, use drugs for disinfection. No more than 80 stocking densities per square meter. The feed requires fine, fine, soft, fresh, animal-based fish, shrimp, snails, clams, livestock and poultry organs, etc., supplemented by vegetable melons, vegetables, and wheat bran. It is advisable to feed artificial compound feed with a protein content of about 40%.
The depth of juvenile turtle pool is generally 20-30 cm, and the fish should be regularly sterilized with drugs in the breeding to prevent the occurrence of diseases.
After entering in October, when the water temperature drops to 15°C, warming culture conditions should be promptly transferred to greenhouse cultivation. If there is no heating equipment, wintering measures should be taken, such as the outdoor pool membrane insulation method: first put sediment in the pool, pour water, so that the mud is moist, hand to mud into a group, not water, but also So that juvenile turtles can account for the degree of sediment. Do not feed during the winter, but when the silt is too dry, sprinkle water properly to maintain the necessary humidity. When the temperature is too low, the straw can be covered with straw insulation.
(2) Feeding of young turtles: Currently, most of the hatchlings use warming culture. When the water temperature drops to 15°C in October each year, about 15 g of turtles are transferred to the greenhouse. Hot water or boiler heating can be. The water temperature is preferably controlled at 28 °C to 30 °C. The size, shape, and heating equipment of the aquaculture ponds can be referenced to soft-shelled turtle breeding equipment, but more rest benches should be provided.
Juvenile turtle stocking density is generally about 30 / square meter. The best use of compound feed, protein content should be about 40%, daily feed about 3% -5%. The feed must be mixed with some melon and leafy green materials and minced or squeezed into juice. At the same time, some internal medicines should be regularly added to prevent diseases. Daily from 8 to 9 am, 4-5 pm When feeding each time, each dose will be full and there will be no leftovers.
When the hatchlings are warmed and cultured, the water should be changed once every three to five days. Before the new water is injected, the bottom bait should be removed to keep the water clean. Every time the water is changed, the difference between the temperature of the input water and the discharged water generally does not exceed 3°C, and the amount of water changed is 1/3 of the total amount of water. If the whole pool changes water, the bottom of the tank should be washed and dried. Every week, we must also use quicklime water to splash and regularly disinfect drugs in order to achieve the purpose of improving water quality, sterilization and disease prevention.
