Technique of Artificial Breeding Snapping Turtle

Crocodile tortoise, is the oldest reptile, one of the world's largest freshwater turtles, known as the king of freshwater animals, is divided into two species, commonly known as alligators and alligators.

1. Good environmental factors.

When a water turtle lives in the water, the depth of the water for raising the turtle is generally slightly higher than that of the back of the turtle. it does not need to be too deep, and no more than 2 times the height of the back of the tortoise. It is best to provide a stone above the surface of the water for the turtle to climb to bask in the back. if the turtle needs sunshine, if it is kept completely indoors, let him bask in the sun more than ten minutes a day. It is recommended to keep it in the southeast where the sun can be exposed for about 1-2 hours (there is no need for long direct sunlight), and provide shading conditions (you can put a small piece of wood on the top of the tank for partial shading) to avoid heatstroke. In summer, we should pay attention to prevent the growth of algae in the tank, you can buy algae removal agents, which are sold in general aquarium stores. The bottom of the cylinder can be covered with small pebbles or large pebbles. However, if it is paved, it will be very troublesome to change the water. Beginners suggest using a bare tank, but nothing will be laid. Don't put water plants in the water.

2. Good water quality.

In view of the fact that under the condition of high-density intensive turtle culture, the turtle has more food intake and excreta, and the water temperature is higher, even if the feed is green feed, it is easy to pollute the water quality and produce more harmful substances in the water, especially ammonia nitrite and H2S, and the water quality can be effectively improved and harmful substances can be reduced by sprinkling and bottom application of photosynthetic bacteria. When adding new pool water, 10 × 10-6 15 × 10-6 photosynthetic bacteria are applied at the same time; changing water is also an effective way to control water quality, the water depth of about 20 cm can be changed once a day, and the water depth of 30 cm can be changed every 2 days. Do not change the water for many days, do not make the water stink. Quicklime can be sprinkled every 7 ~ 10 days with a concentration of 70 × 10 ~ 6, and should not be used at the same time.

3. Control of water temperature.

Crocodile turtles like to live in clean water. Therefore, attention should be paid to the replacement of new water in the process of feeding. Moreover, to ensure the survival rate of crocodile turtles, it is necessary to maintain a stable water temperature. The scientific regulation of water temperature directly affects the weight gain and survival rate of adult turtles. Under the condition of 18 ℃ ~ 20 ℃ for a long time, the growth rate of crocodile turtles is several times slower than the optimum water temperature of 30 ℃ ~ 31 ℃. Therefore, it is important to keep the water temperature of turtles within 30 ℃ ~ 31 ℃. On the other hand, when the tortoise ponds that are changing water or exposed to the outside world happen to encounter severe weather such as heavy rain or sudden changes in temperature, we should take precautions in time to avoid the variation of water temperature greater than 2 ℃.

4. Feed feeding.

Crocodile turtle eating habits are more miscellaneous, fish, Loach, meat and so on can become its food. When feeding crocodile turtles, the amount of compound feed is generally 1.5%, 2.5% of the total body weight of crocodile turtles, and 5% of live feed. Feed regularly and quantitatively 3 times a day, and the range of food should be uniform and wide.

5. The hibernation of crocodile turtles.

When the temperature drops below 13 ℃ from October to May, the tortoise begins to hibernate until the temperature rises to 18 degrees Celsius. Hibernating turtles don't eat and don't move, they just sleep. The simplest way to hibernate is to move the turtle into a dark and quiet place indoors, hibernating in shallow water (just over the back armour) and changing water once a month. In addition to changing water, try not to disturb the turtle. Be careful that the temperature is not lower than 6 degrees, otherwise the life of the turtle will be endangered. However, it is recommended to use heating sticks in winter, because the mortality rate of natural hibernation is very high. Heating rod is the kind of tropical fish, the temperature is set at about 30 degrees, with a lid on the tank.
