Mauremys nutica, commonly known as the stone turtle in Guangxi and Guangxi, is classified under the order of Tortoise, Tortoise and Turtle. It is distributed in Jiangsu, Zhejiang, Anhui, Guangxi, Guangdong, Hainan, Fujian, and Taiwan. Distributed in Vietnam. Yellow-throated turtles are nutritious and have high ornamental and medicinal values.
1. Morphology and life characteristics of the yellow-throated turtle (1) Morphological characteristics Small head, smooth top, middle sulcus, clear tympanic membrane, two pale yellow lines behind head, yellow throat, and flat back The central ridge is very ridged and the trailing edge is slightly jagged. Carapace brownish or brown, plastron front flat, posterior edge of the deep lack of engraved, plastron is yellow, each piece of scutellum with large stains on the outside of the ink spot, a bridge obviously, back and abdomen by a ligament connected. Limbs are flat, with fingers and toes between the digits and claws. Short tail.
(2) Living habits Wild animals live in rivers, rice fields, lakes, and often go to nearby bushes and grasses. Like to eat fish, shrimp, snails, cockles, worms and other animal food, but also eat some tender plants. The breeding season is from May to October each year, and from mid-November to the end of March of the following year is hibernation. In Guangdong, the breeding season is from the end of April to the end of August, and from mid-December to the end of February the following year is the hibernation period.
2. Selection and breeding of species of turtles (1) Selection of species of turtles Sexual maturity of yellow-throated turtles generally takes more than 5 years. If it is a wild yellow-throated turtle, as long as there are more than 450 grams, it can generally be used as a species of turtle. Male yellow-throated turtles have longer turtle dorsal carapace, have a central depression in the plastron and a long tail, and the anus is farther from the posterior edge of the plastron. Females have short backs, flat plastrons, and short tails.
Turtles should be selected for healthy, non-injured and disease-free individuals. Such as turtle shell, skin injury or inflammation, the eyes of the cornea is white, cloudy, kiss, nostrils, neck, limbs, swelling can not be selected. Turtle, shiny skin, telescopic head and neck, turning freely, crawling limbs powerful, no trauma, full body can choose.
(2) Breeding and management of species of turtles 1 species of turtle ponds Turtle ponds are cement structures with a slope of about 25 at the bottom of the pond (the turtle pond is divided into three parts, and the lower part is a reservoir with a water depth of about 30 cm; the middle part is a feed bait and activity yard. : The upper part of the spawning ground is covered with fine sand, and the spawning ground has a roof covering to shade and block the rainwater.The pond discharges the water lotus, accounting for about 1/4 to 1/3 of the pool surface. Planting some of the flowers and plants, the turtle pool is covered with a cloth to create a cool and quiet environment for the turtles.
2 Turtle ponds and turtles are required to undergo a thorough clearing before the purchase of turtles to remove harmful and toxic substances in the pond and kill various pathogens existing in the pool. Commonly used drugs are bleach and potassium permanganate. The bleaching powder is dissolved in water and the concentration is 200.000001. Potassium permanganate concentration was 150.000001, Quanchiposa.
Turtle disinfection commonly used method is medicine bath method, available potassium permanganate, malachite green and furazolidone. The potassium permanganate bath concentration was 150.000001, or malachite green 50.000001, or furazolidone 250.000001, both soaked for 30 minutes.
Three species of turtle stocking and management turtles were placed in the turtle pond at a ratio of 2:1. The stocking density was 4-6 per square meter. Newly purchased turtles do not feed immediately due to abrupt changes in their living environment. Generally, they begin to lure after three days. The bait is mainly composed of viscera of animal fresh materials such as small fish, shrimp or poultry, together with some fruits and vegetables such as apples, bananas and tender vegetables.
When the temperature exceeds 15°C, the yellow-throated turtle begins feeding. Above 20°C, feeding is normal. At this point has entered the critical period of female reproductive development. Must be daily qualitative, quantitative, timing, positioning feeding. The bait should be fresh and must not be spoiled. Feeding amount to the turtle to eat a little bit of this standard. The foods fed daily are placed on a fixed land location, allowing the species to develop habits of feeding on schedule. The temperature is below 25°C and feeds once a day. The feeding time is preferably 3pm; the temperature is above 26°C and is fed twice a day, once in the morning at 7:00 and once in the afternoon at 6:00.
3. Spawning and hatching In Guangzhou, Yellow-lucking turtles begin spawning at the end of April each year. The peak period is May-June and ends at the end of August. Spawning can occur many times a year, with 1-7 spawns each time. The average number of eggs was 2.5.
1. Spawning At the end of April or early May, yellow-lucking turtles begin to spawn. Spawn more at night or at dawn. Before the female turtle lays eggs, he climbs into the spawning ground and chooses a suitable location to begin digging. The forelegs are fixed to the body, the hind limbs are dug for dredging, and the tail helps to sweep the sand. Head and neck forward and always pay attention to the surrounding movement. When the cave is dug, it begins to spawn. After producing an egg, use the hind limbs to arrange the eggs in the nest. Eggs will cover the hole. Use the hind limbs to put the sand plover into the burrow, use the gravity of the back half of the body to compact the burrow, and flatten the burrow, and then leave. No ovulation behavior.
Yellow-shouldered turtles produced the largest amount of eggs in May-June, accounting for 76.3%, with 1-7 eggs, and 2-3 eggs per litter, accounting for 58.4%. Egg weight 10-20 grams, an average of 14 grams, long diameter 3.41-5.53cm, short diameter 1.75-2.67cm.
2. Incubation of turtle eggs Incubators are made with foam boxes or wooden boxes as incubators. The walls of the foam box are drilled for ventilation. Laying 10cm deep sand. Egg buried depth 3-4cm. 200 square centimeters of the box can be placed around 50 eggs. The humidity of the sand is 5-10%. It is shaped by the sand in the hand and the ground is the basis for the dispersion. If the water content in sand is too high, it will easily accumulate water and prevent oxygen from entering the egg. The embryo will die due to lack of oxygen. Too dry, easy to introduce embryos and die. To improve the hatching rate of turtle eggs, maintaining the proper humidity is the key. After the eggs are placed, a label should be inserted to indicate the date and quantity.
During incubation, the temperature is maintained between 25-32°C. For regular sand spray, the indoor relative humidity is maintained at 80-93%. The fertilized eggs of the yellow-throated water turtle can hatch hatchlings after 54-112 days of hatching. The average incubation time was 73.8 days.
4. Juvenile turtle breeding (1. Hidden tortoise pool Chito turtle pool is generally cement structure, the bottom of the pool has a gradient, 3/4 is a pool, the water depth is 20cm, and 1/4 is land. The upper part of the turtle pool should be shaded by shade cloth.
(2) Juvenile tortoises hatch young hatchlings weighing between 6.4 to 13 grams, with an average of 9.75 grams. The eggs are generally large, hatched hatchlings are also large, eggs are small, and hatched hatchlings are also small. The juvenile turtle is in a special pot and does not need to feed until the yolk sac disappears completely and can be moved into the hatchling pool.When it is transferred into the hatchling pool, the hatchling should be soaked and disinfected with a potassium permanganate solution of 10.000001. It can be fed and cooked after entering the pool. The chicken, duck yolk or chopped pork liver can be fed with minced fish or dip material after one week.The stocking density of juvenile tortoises is about 100/sq.m., change the water in about two days depending on the change of water quality, and the amount of bait is eaten by juvenile tortoises. The leftovers should be the ones on the land.The bait should be removed on land and the leftovers should be promptly swept away. Feeding should be carried out in the morning and evening. It is normally fed twice a day, and the feeding frequency can be adjusted depending on the temperature. The hatchlings hatched at the end of August After 3 months of feeding, the average body weight increased from 9.75 g to 23.14 g, the net weight of the individual was 13.39 g, and the average daily weight gain was 0.149 g, and the maximum individual was 40 g.In general, hatched individuals were large and grew rapidly. Individuals who are young are slow to grow, and the greater the difference, the greater the gap.
In the process of juvenile hatchlings, care should be taken to prevent the intrusion of predators such as snakes, rats and cats.
