Snapping turtles have two species, namely, large snapping turtles and small snapping turtles. The large snapping turtles can weigh more than 100 kg. Fertility can hurt people and should not be cultured. Snapping Turtle, commonly referred to as Snapping Turtle, usually weighs 5–10 kg, is mild and does not take the initiative. Snapping Turtle has three major characteristics: First, the growth rate is surprisingly fast, the annual increase in natural temperature is as high as about 1kg, half temperature control breeding (heating temperature below 18°C), annual weight gain 1.5-2kg, the highest record year With a weight gain of 2.5kg, its growth rate is unmatched by other turtles and earthworm species in the world. Second, cold, high temperature, miscellaneous food, less disease, strong ability to adapt to the environment, in all the provinces of China, the natural state and temperature control conditions can be cultured. Particularly valuable is that snapping turtles do not require much water, and northern cultures do not need to worry about water shortages. Third, set food, medicinal and ornamental in one.

First, the biological characteristics of snapping turtle

Snapping turtle looks strange, looks exactly like a crocodile, kissing out, the head out of the body, can not be retracted into the carapace, the upper and lower jaw slightly pointed, eyes short, long thick tail, above the length of fleshy, like a crocodile tail.

Third, the snapping turtle breeding techniques

1. To build a sub-culture: turtle pond is suitable for 15-20 square meters, deep pool l. 5m, water depth 0.8-lm. Each group of square turtles can be stocked with 1 species (1 males and 2 females) or medium turtles 3 groups or hatchlings 5-10 groups or hatchlings 10-20 groups. Grow.

2. Scientific feeding: In the early spring and early winter, feed 1 at noon every day. The end of spring to late autumn is the peak season for food intake. Feeding twice a day, 40% at 9:00, and 60% in the evening, the food should be fixed in one place. The food that was dropped was eaten within 150 minutes, and the next time, you could eat less. Food should be cut to large, hard soaked, raw and cooked can be, small turtle feeding nutritious finely chopped feed, spoilage feed can not be used. Appropriate collocation of vegetable, fruit and vegetable feed.

3. Regular water change and disinfection: large pool, 20-50 days part of the water change 1, small pond 2-3 days or 6-7 days part of the water l times, transparency is maintained at 10-20cm, according to the situation in the winter as little as possible Change the water, but change the water with a pot. Pool water is usually sterilized with 10ppm bleach for 20-30 days, which can prevent the occurrence of turtles.

4. Warming and cooling: In order to ensure the normal growth of snapping turtles throughout the year, when the temperature is about 18°C ​​in winter, the pool water must be warmed to keep the pool water temperature no lower than 25°C. In summer, the pool water must be kept at 30cm above ground. To shave more than l/5, raise some duckweed in the pond and plant trees around it. If necessary, inject new water to cool it so that the water temperature does not exceed 45°C. Snapping turtles can also be housed in indoor areas (such as rooms, plastic greenhouses, basements, etc.) or reared in pots, which is conducive to warming and cooling, maintaining appropriate temperatures all year round, and promoting the growth of snapping turtles. The breeding of common snapping turtles is often done indoors.

5. Reproduction and hatching; wild snapping turtles begin spawning in the third year. Snapping turtles that have been reared for 18 months or grow to more than 1 kg will begin to spawn. May-May and September-October natural mating, May-August for the spawning season, female turtles spawn at night, 30-120 eggs a year. 3-4 batches of output. Incubation method: The incubator is 80m high, 50cm wide and 80cm long. Several leak holes are drilled in the bottom of the box, 5cm thick sand is placed, 5cm fine sand is placed, the eggs are placed on the sand (animals with white spots are facing up), and the covers 5cm fine sand, then covered with rodents, snakes. The coarse sand used was first scalded with boiling water. Eggs are inspected once a day. If the surface is dry on the surface of the sand, it should be moisturized and moistened. It is advisable to loosen the sand in groups. The hatchlings can hatch at 65-75 days under natural temperature, and the hatching rate is 93%-96%. Such as using a constant temperature of 3O °C, relative humidity of 80% -90%, after 50-60 days to hatch hatchlings, hatching rate of 98%. After the hatchlings are hatched, they are allowed to move in the incubator for several hours until the umbilical cord falls off. That is, they are transferred into a 200 ppm potassium permanganate solution and sterilized for 5 minutes, and then put in clear water for rearing.

6. Disease prevention and treatment: As long as strict disinfection of small turtles and pool water, generally have little disease, occasional minor illnesses, the right medicine, you can treat. Traumatic inflammation and colds can be treated with cephalosporin spices; gastroenteritis is fed with fluocin or injection of antibiotics; dyspepsia is treated with multi-enzyme solution or yeast tablets; hydromycosis is dipped with 100ppm malachite green solution for 15 minutes or Salt water immersed turtle.
