1, species selection: choose the board flat and large body fat, back is brown or dark green, the abdomen is milky white or light red breeding. 2, breeding pool: according to the size of the breeding pool to control the breeding density. 3, water temperature: the temperature is generally controlled at 20-30 ℃ is more appropriate. 4, water quality: water transparency should be controlled at about 30 cm. 5, water depth: it is desirable to maintain the Water depth: 0.3-0.4 meters, the highest water level should not be more than 1 meter. 6, feeding: snappers like to eat animal feed, feeding amount to 1 hour to eat up as well. 7, disease prevention and control: snappers in the pool as well as the breeding pool need to be disinfected on a regular basis.

I. Turtle breeding methods

1, species selection

Choose turtle fry, you can choose the plate flat and large body fat, the back shows brown or dark green, the abdomen is creamy white or light red, so that the turtle reproduction ability is strong, it's better to keep. No matter what kind of turtle seedlings into the pool must be graded about 15 days of temporary breeding, to be adapted to the environment and then put into the breeding pool.

2. Breeding Pond

In most cases, the breeding pond is used to breed a large number of softshell turtles, and the density of softshell turtles should be controlled according to the size of the pond, and should not be too dense. If it is a self-propagation, self-breeding, self-farming turtle farms should consider the new turtle pools, young turtle pools, juvenile turtle pools, 3-year-old turtle pools, adult turtle pools, 5 kinds of turtle pools supporting the construction.

3, water temperature

Snappers are sensitive to water temperature, if the water temperature is too low, it will greatly affect the appetite of snappers, and its activity will be reduced. Generally speaking, the temperature control in 20-30 ℃ is more appropriate. In the process of turtle hibernation, the same need to regulate the temperature, not too low.

4, water quality

Snappers have high requirements for water quality, they like clean, water transparency should be controlled at about 30 centimeters. Water change is the main way to directly improve water quality, so pay attention to regular water change in the breeding process. At the same time, pay attention to check the protective facilities to prevent the turtle from escaping and also prevent the invasion of some natural enemies.

5, water depth

Snappers should keep the water depth of 0.3-0.4 meters during the juvenile period, if it is too small, you can add some, and the highest water level should not be more than 1 meter.

6, feeding

Suitable for snappers feeding is generally underwater feeding, bait from the surface of the water 2-3 cm can be. The amount of feeding to eat within 1 hour is good, do not feed too much, otherwise it will cause a relatively large burden to the snapper's digestive system. Snappers are omnivorous animals, like to eat animal feed, but also can eat some vegetables and fruits and other plant feed. When feeding, pay attention to the combination of meat and vegetables, a reasonable combination can increase the growth rate of snappers.

7, disease prevention and control

Snappers need to be sterilized before entering the pool, such as soaking in salt water. In the process of breeding, we should also pay attention to the prevention and control of diseases, the more common diseases are mycosis, white spot disease and so on. At the same time, the breeding pond also needs to be disinfected regularly.

Second, the main points of turtle farming technology

1, regulating the aquaculture water

The indicators of the aquaculture of the turtle water body are: dissolved oxygen to maintain more than 5, pH value stabilized between 7.5-8, alkalinity, hardness stabilized at 3.0-3.2 milligrams per liter, the content of ammonia nitrogen is less than 0.02 mg/liter, nitrite concentration below 0.1 mg/liter, and pool water transparency between 20-30 cm.

2, timely sewage, scientific drainage

According to the water color regularly discharged bottom organic matter. Adhere to the sewage 2-3 times a day, in order to save the warm water of the breeding pool each time to drain the residual bait and feces, that is, no black sewage outflow as a limit.

3, reasonable pools, timely clearing of the pool

In the breeding of snappers, the same pool of snapper fry should try to achieve the same specifications, so as to avoid the size of the bite, the growth of the difference between the disparity. Do a reasonable division of the pool, the size of the turtle hierarchical feeding, not only conducive to the management, but also easy to grasp the implementation of the feeding program as well as follow-up. In addition, timely cleaning of the pool is also essential.

When washing the pool, the snapper will be transferred to the reserve pool, the original pool with cold water to fully rinse the sand layer of dirt, to the sand layer basically no black sewage outflow, the sand layer color black to yellowish as appropriate.

4, the establishment of production files

In the breeding, the baiting situation, the occurrence of disease, snapper specifications and the number of records on file, for the convenience of the technical staff to refer to, so as to formulate the next stage of the production program as well as the basis of the technical measures to be taken.

5, control the quality of feed

Selected snapper feed to meet the appropriate standards, and pay attention to the proper preservation. The feed should be used now, and the feed should be checked for mold and deterioration before each feeding. In addition to adhering to the ? Four fixed (timing, quantity, location, quality)? In addition to the principle of feeding, the amount of feeding also needs to be adjusted according to the eating situation of the turtle.
