How to raise snapping turtle seedlings
First, the selection of snapping turtle seedlings
First of all, it is not recommended to buy turtle seedlings in winter. The weather is cold, and the turtle seedlings can't stand the toss. If the temperature can be kept within a safe range (4-30 degrees Celsius), the first thing to choose a turtle is to look at the appearance of the turtle. The tip of the mouth, limbs, claws and tail are intact, and there are no wrong nails, rotten nails, colds (runny nose and stuffy nose), pneumonia (breathing with open mouth) and parasites on the back nail. Second, it depends on the state. Generally, the seller is allowed to feed face to face, take out the tail of the water and bend to one side, touch the hind legs of the chin and stand up or even open his mouth to bite. This can basically be called a good state. As for the color of crustaceans and meat, it depends on personal hobbies.
Second, the breeding of snapping turtle fry
1. Temperature control device. Advanced patented technology can be used in both small and large greenhouses. Automatic hot water circulation energy-saving heating device for turtle greenhouse? , has obtained the patent certificate with patent number ZL 0 12 17344.4 issued by China National Intellectual Property Administration. The biggest feature of this patent is that anthracite is used to automatically heat the air in the greenhouse and the water in the regulating pool. The key is the automatic circulation of hot water to ensure the need of isothermal water change. The daily coal consumption is only 500 grams per square meter, and the energy saving effect is remarkable.
Step 2: Set the table.
Put asbestos shingles into turtle pond obliquely, underwater 1/3, and water surface 2/3. Feeding begins under the table and gradually moves to the water for feeding, which is beneficial to observe the feeding situation and reduce the residual bait.
3. Disinfection and disease prevention
After being diluted with quicklime slurry regularly, it spills all over the pond, and the turtle water is automatically disinfected regularly with advanced ozone generator, which has good effect and low cost. 4. It is best to make your own feed, buy small feed production units and use advanced feed formulas. The basic ingredients of crocodile turtle feed are white fish meal and? Green feed additives such as starch, plant protein, minerals, vitamins, probiotics and prebiotics can be added to promote the growth of snapping turtles, reduce the occurrence of nutritional diseases and improve the survival rate of breeding.
How to raise snapping turtles
Good environmental factors
Water turtles live in water. Generally, the water depth of turtle breeding is slightly higher than that of turtle back, not too deep, and at most not more than twice the height of turtle back. It's best to provide a stone above the water for the tortoise to climb up and bask in the back. The tortoise needs sunshine. If they are completely indoors, they should be exposed to the sun for more than ten minutes every day. It is recommended to place it in the southeast where sunshine can be obtained 1-2 hours (without long-term direct sunlight), and provide shading conditions (a small piece of wood can be placed on the top of the tank for partial shading) to avoid heatstroke. Attention should be paid to prevent algae from growing in the tank in summer. You can buy algaecides, which are usually sold in aquarium stores. The bottom of the tank can be covered with pebbles or pebbles. But if it is paved, it will be very troublesome to change the water. Novices suggest using bare cans, but nothing is paved. Do not put aquatic plants in the water.
Good water quality
In view of turtle's high food intake and excreta and high water temperature under intensive high-density culture conditions, even if the feed is green, it will pollute the water body quickly, and more harmful substances, especially ammoniated nitrite and H2S, will be easily produced in the water. By spraying and applying photosynthetic bacteria at the bottom, water quality can be effectively improved and harmful substances can be reduced. Apply 10 at the same time when each pool is filled with fresh water? 10-6~ 15? 10-6 photosynthetic bacteria; Changing water is also an effective way to adjust 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 once every two days. Don't change the water for a few days, and don't let it stink. Quicklime can be sprayed once every 7 days to 10 day with a concentration of 70? 10-6, and pay attention to cross application with photosynthetic bacteria, not at the same time.
Water temperature control
Crocodile turtles like to live in a clean water environment. Therefore, attention should be paid to replacing fresh water during the feeding process. Moreover, to ensure the survival rate of snapping turtles, it is necessary to keep the water temperature environment stable. The scientific control of water temperature directly affects the weight gain and survival rate of adult turtle culture. Under the condition of 65,438+08℃ ~ 20℃, the long-term growth rate of snapping turtle is several times slower than the optimum growth water temperature of 30℃ ~ 365,438+0℃. Therefore, the water temperature for raising soft-shelled turtle must be kept between 30℃ and 365438 0℃. On the other hand, when the turtle pond that is changing water or exposed to the outside encounters bad weather such as heavy rain or sudden change of temperature, preventive measures should be taken in time to avoid water temperature fluctuation greater than 2℃ as far as possible.
Feed feeding
Crocodile turtles have a mixed diet, and fish, loach and meat can all be their food. When feeding snapping turtles, the dosage of compound feed is generally 1.5%-2.5% of the total weight of snapping turtles and 5%- 10% of fresh feed. Feed regularly and quantitatively three times a day, and the range of food to be fed should be uniform and extensive.
Hibernation of snapping turtles
When the temperature dropped below 13℃ from June to May of the following year, turtles began to hibernate until the temperature rose to 18℃. Hibernating turtles can't eat or move, but sleep. The easiest way to hibernate is to move the tortoise to a dark and quiet place indoors, hibernate in shallow water (the water has just passed through the shell) and change the water once a month. Try not to disturb the tortoise except changing the water. Be careful that the temperature should not be lower than 6 degrees, otherwise it will endanger the life of the tortoise. However, it is recommended to use heating rods in winter because of the high mortality rate of natural hibernation. The heating rod is the kind of tropical fish, the temperature is set at about 30 degrees, and the cylinder has a cover.
In fact, crocodile turtles are a bit sinister, but their vitality is not very tenacious. If it is not well cared for, its mortality rate will become very high. Turtles are carnivores, so you need to feed them fresh meat regularly every day, and occasionally feed some shrimps to improve their taste, so that they don't need to put food in the water when they hibernate. After feeding the snapping turtle, we should pay attention to changing it to fresh water, because it has higher requirements on water quality and can survive better in fresh water.
