How do you keep the soft-shelled turtle? Scientific technique of raising soft-shelled turtle

Soft-shelled turtle is what we often call the son of a bitch, the son of a bitch is a derogatory term, but the nutritional value of soft-shelled turtle is very high, so the industry of breeding soft-shelled turtle is still very good, with good breeding prospects. There are many ways to cultivate soft-shelled turtle, which can be divided into factory culture and pond culture. Let's follow the editor to learn more about it.

How to raise soft-shelled turtle

1. Soft-shelled turtles are ferocious and aggressive by nature, bullying and bullying among groups is very common, and they will cannibalize the same kind when food is scarce. So feed enough food in the feeding process and pay close attention to their behavior.

2. Soft-shelled turtles are amphibious and breathe with their lungs, so there should be a sufficient area of land beach around or in the center of the soft-shelled turtle pond so that it can carry out land activities. The soft-shelled turtle is sensitive to the sound of the surrounding environment, as long as there is a little movement around, the soft-shelled turtle can quickly dive into the underwater silt, so the breeding environment must be kept quiet. If the soft-shelled turtle is often frightened, it is very disadvantageous to its growth and reproduction.

3. Soft-shelled turtles like to stay in an environment with good water quality, so the owner must change the water frequently, about every 3 days.

4. Soft-shelled turtle is an aquatic omnivore and likes to eat animal bait. Juvenile soft-shelled turtles feed on aquatic insects, water earthworms, tadpoles, shrimps and so on. Adult soft-shelled turtles feed on field snails, clams and other molluscs, fish, shrimp and animal carcasses, as well as vegetable, fruit, miscellaneous grains and other plant feed. Little turtle, you can cut the meat into minced meat and feed it to him slowly.

5. When using fresh materials for feeding, they must be disinfected, cleaned and used now to avoid corruption and deterioration. Feeding should be in the form of feeding, and the bait is 2mi 3cm from the surface of the water. The soft-shelled turtle is timid, so the interference to it should be minimized when feeding.

6. Soft-shelled turtles should bask in the sun more, because the ultraviolet rays in the sun can kill the pathogenic bacteria on the body surface, promote the healing of the injured body surface, and raise the body temperature and promote food digestion by basking in the back.

The soft-shelled turtle hibernates in the south at the end of November, about a month earlier in the north. Hibernation does not need another place to prepare, just spread half of the sand out of the water in the basin. It may climb out of the water and sleep motionless on the sand for dozens of days, and then unwittingly go into the water and sleep for dozens of days.

8. Pay attention to mosquitoes in summer. Soft-shelled turtles are afraid of mosquitoes.

Scientific technique of raising soft-shelled turtle

I. Construction of soft-shelled turtle ponds:

According to the living habits of the soft-shelled turtle, the soft-shelled turtle likes to be quiet and afraid of sound, Xiyang is afraid of the wind, and Xijie is afraid of dirt. The environment for the construction of the pond should be selected according to these characteristics. For example, if it is a turtle farm with self-propagation, self-breeding and self-cultivation, it is necessary to consider the supporting construction of five kinds of turtle ponds: new turtle pond, juvenile turtle pond, juvenile turtle pond, 3-year-old turtle pond and adult turtle pond. The proportion of them is 4, 1, 2, 4, 9, respectively. This can maximize the use of land, water and other natural resources, so that turtle culture supporting development, its own series, more conducive to reduce costs and improve economic benefits.

If there is no sandy soil at the bottom of the pond, it should be mixed with a part of sandy soil, and a drying table and a bait feeding table should be built on the edge of the pond and on the edge of the pond, respectively, for the soft-shelled turtle to bask in the back and feed. An anti-escape wall should be built around, brick and asbestos tiles can be planted vertically, with a height of about 1 meter.

Second, choose soft-shelled turtle fry.

At present, the source of soft-shelled turtle fry is mainly from two aspects, one is factory breeding and professional household mass production, and the other is wild soft-shelled turtle of different size in the market. But no matter which kind of soft-shelled turtle fry, when entering the pond, it must be graded and temporarily raised on the left side for 15 days, and then put into the culture pond after adapting to the environment. Small soft-shelled turtles with scars and adult fish (some of which are hooked) should be raised separately, and then be thrown into the pond according to the specifications after the injury is cured. For those seedlings who are slow to respond and have difficulty in moving, they should be thrown into the pond after they have been cured.

Third, release density.

Generally speaking, 10-150 kg per mu of 2-3-year-old young fish. No more than 200 kilograms at most.

IV. Daily management

1. Water temperature control. The best temperature range for the growth of soft-shelled turtle is the water temperature of 20 ℃ ~ 30 ℃. The soft-shelled turtle begins to eat when the water temperature is higher than 20 ℃, and the food intake increases with the increase of water temperature. The feed conversion rate will decrease when the water temperature is lower than the optimum temperature; when the water temperature is higher than the optimum temperature, the feed conversion rate will also decrease due to the increase of activity, so the water temperature should be kept in the optimal temperature range, too high or too low will cause feed waste.

2. Feeding method. Feeding under water is suitable for the feeding habit of soft-shelled turtle, which can accelerate the feeding speed of soft-pellet feed than that of block feed.

3. Control of feeding quantity. The feeding of soft-shelled turtle is greatly affected by the change of environmental factors. When the air temperature, water temperature and medication change, the feeding amount should be adjusted taking into account the influence on the soft-shelled turtle. Generally, the underwater feeding should be controlled within 30 minutes. When the soft-shelled turtle is overfed, it grows too fast, which can easily lead to the increase or overload of the physiological load of the soft-shelled turtle, resulting in visceral damage and visceral diseases.

4. Feed selection. The feed cost accounts for about 40% of the breeding cost, and the feeding method and the quality of the selected feed determine the success or failure of breeding cost control. Through the final benefit analysis, comparing the price of high-quality feed and inferior feed and the comprehensive breeding cost, we can get out of the misunderstanding of choosing feed only to look at the price.

5. Water quality control. Soft-shelled turtles are naturally fond of clean and afraid of dirty. a good water environment is an important condition for the stable growth of soft-shelled turtles.

V. Disease control

The juvenile armour should be disinfected before entering the pool and soaked in 2 ‰ saline solution for 30 minutes before entering the pool. Beware of the occurrence of mycosis before the body weight of the soft-shelled turtle is 50 grams. At this stage, the physique of juvenile nails should be strengthened and mechanical damage should be avoided. When the soft-shelled turtles weigh 50-150 grams, beware of the occurrence of white spot disease, and bromine and chlorine preparations are the main daily disinfection; weight 50 grams to adult nail, beware of the occurrence of furunculosis.

Is a turtle a turtle?

Soft-shelled turtle and turtle are not the same thing. Let's analyze the difference between soft-shelled turtle and turtle.

1. Head.

Tortoise: the head is round in shape and can be stretched freely. If you touch its head with something, it will immediately retract its head.

Soft-shelled turtle: the head is pointed and cannot be stretched freely.

2. Character.

Tortoise: gentle character, you provoke it, it will shrink its head.

Soft-shelled turtle: he has a bad temper. If he touches his head with something, he will bite you right back.

3. Shell.

Tortoise: the shell is very thick and strong, and there are patterns on the tortoise's shell. Many turtles have different patterns and colors because of different varieties, and the texture of the shell is hemp.

Soft-shelled turtle: the shell is not so thick, the shell of the soft-shelled turtle is smooth, there is meat in the bone, the shell of the stewed soft-shelled turtle is put into the pot together, although there is little meat, it is very delicious.

The living habits of soft-shelled turtle

Wild soft-shelled turtle in the natural environment, like to inhabit clean rivers, lakes, reservoirs, ponds and other waters, and often lie on the sunny bank during the calm day to bask in the sun (commonly known as sun back), using ultraviolet rays in the sun to kill pathogenic bacteria on the body surface, promote the healing of the injured body surface, and increase the body temperature through the sun back to promote food digestion.

During the growth period, the soft-shelled turtle mainly breathed through the lungs. When the water temperature was below 15 ℃, the soft-shelled turtle dived into the bottom of the pond and began to hibernate and breathed by auxiliary respiratory organs such as the Gill tissue of the larynx.

Reproduction of soft-shelled turtle

Under the condition of natural temperature, the soft-shelled turtle can not reach sexual maturity until the age of 4 to 5 years old, and begin to mate when the water temperature is above 20 ℃. Once mating, multiple spawning. The north spawns 2-3 times a year and the south 4-5 times a year. The spawning period is from May to August, and the spawning peak is from June to July. The spawning time is usually in the middle of the night (06am), which is related to the turtle's preference for a quiet environment. The spawning mode of soft-shelled turtle is to dig holes to lay eggs, which is buried with sand after delivery, so a sandy spawning ground should be set up around the pond.

Soft-shelled turtle is loved and sought after by more and more people, so it has become a hot breeding industry, soft-shelled turtle culture is not difficult, but novice farmers should pay attention to learn technology in order to avoid their own risks. The state advocates not to hunt and kill wild animals, so it still supports artificial breeding, therefore, the prospect of artificial breeding of soft-shelled turtle is very good, and there is a broad market.
