CATDOLL : CATDOLL: How to breed soft-shell turtles

1. How to breed soft-shelled turtles

Select turtle fry that weigh more than 3 grams, have thick and straight skirts, and orange-red belly plates for breeding. The recommended area of ​​the turtle breeding pond is about 5 mu. The soil of the pond is preferably clay or loam. Use asbestos tiles and bricks to build a 1-meter-high escape-proof wall. Build a drying platform and feeding platform on the side of the breeding pond. Put the turtle fry in the net cage for 15 days before putting it into the pond for breeding. Feed the turtle with snails, small fish, shrimps, loaches, earthworms, insects, etc.

1. Choose soft-shelled turtle

The skirt of a good turtle fry is thicker and straighter, while a soft, thin and drooping skirt indicates malnutrition. Generally, high-quality turtle fry weigh more than 3 grams. If it is less than 3 grams, it may be caused by malnutrition or poor physique, so it is not recommended to select it. The belly plate of the young turtle is orange-red, the redder the better.

2. Choose a venue

1. The pond conditions generally recommend an area of ​​about 5 mu, with a slope ratio of 1:2. The best choice of pond soil is clay or loam. At the same time, a sunbathing platform and a feeding platform should be built beside the breeding pond for the turtles to bask and feed. In addition, escape prevention facilities need to be built. Asbestos tiles and bricks can be used around the breeding pond to build an escape prevention wall with a height of 1 meter.

2. The pond water source is pollution-free, the pH value is between 7-8.5, the dissolved oxygen is above 5 mg per liter, and the water temperature is maintained at around 30°C. There should be no large chemical plants or livestock and poultry farms around the breeding pond. The traffic conditions around the pond should be good for convenient transportation.

3. Free-range

The newly bought turtle fry cannot be put into the breeding pond immediately. Some of the turtles can be placed in the net cages in the breeding pond for about 15 days. If the turtles do not show any discomfort or abnormality, they can be released on a large scale. The stocking density depends on the size of the breeding pond and other factors. 100 kg to 150 kg of 2-3 year old young turtles can be released per acre.

4. Feeding

1. Feeding turtles can be done with field snails, small fish, shrimps, loaches, earthworms, insects, etc. in paddy fields. Feed them 2-3 cm away from the water surface. Keeping a certain distance can minimize interference with them. When feeding fresh feed, it needs to be disinfected and cleaned, and eaten immediately after preparation to avoid feed corruption and deterioration.

2. Soft-shelled turtles are nocturnal animals, so they almost do not need to be fed during the day. They can be fed at 7-8 pm or at 5-6 am. The weight of each feeding should account for 5% of the turtle's body weight.

5. Change the water

Change the water every 8-10 days. Each time you change the water, drain 20 cm to 25 cm of the water level in the pond and then fill it up again.

2. How to breed soft-shelled turtles

Constructing ponds: Before raising turtles, choose a place with abundant water resources and a wide area to construct a pond. Selecting seedlings for stocking: Select healthy, uniform and lively seedlings. Feeding method: Feed in the early morning and evening every day, mainly by throwing. Water quality management: Change the water every 15 days in spring and autumn, and change the water every week in summer.

Soft-shell turtle breeding method 1. Building ponds

Before breeding soft-shelled turtles, choose a place far away from the city, with abundant water resources, sunny and wide, to build a turtle pond with a depth of 1.5-2 meters. Divide the area into ponds for different purposes such as juvenile turtle ponds, adult turtle ponds and parent turtle ponds. Install escape-proof devices around the pond and build an island in the center of the pond.

2. Select seedlings and stock them

When releasing soft-shelled turtle fry, you should select healthy, uniformly sized, intact and lively fry. It is best to release them in March and April. Disinfect the pond before releasing them, soak the fry in a diluted potassium permanganate solution, and put them into the pond after cleaning. The density should not exceed 15 per square meter.

3. Feeding method

Soft-shelled turtles are omnivores, mainly feeding on animal food with a small amount of plant food such as aquatic plants or fruits and vegetables. They are fed in the early morning and evening every day, with the amount of fresh feed not exceeding 40%. They are mainly fed by throwing, with the bait placed 3 cm from the water surface.

4. Water quality management

There are certain requirements for water quality during turtle farming. The water should be changed every 15 days in spring and autumn, and once a week during high temperatures in summer. The amount of water changed should not exceed 30% of the total water volume in the pond. The transparency of the water should be kept at about 30 cm. When changing the water, sprinkle quicklime to adjust the dissolved oxygen content.

3. How to raise soft-shelled turtles?

If you want to get good economic benefits from raising soft-shelled turtles, you must do the following three steps well, namely, calculate the accounts well, raise the turtles well, and sell them at a good price.

(1) Calculate the accounts carefully Before raising soft-shelled turtles, you must first calculate the accounts carefully. The reason why many farms lose money is that they follow the trend of others raising soft-shelled turtles and start raising them, without calculating whether the changes in the market and costs after raising them are beneficial to their own breeding. Following the trend, there is no market after the turtles grow up, and in the end they can only watch others make money while they end up in a mess. Calculating the accounts carefully mainly involves understanding the market changes of production materials and the price trends of the product market, and then controlling and managing the breeding costs. Finally, you can only start breeding when you are sure that it is profitable. (2) Raise soft-shelled turtles well Before you start breeding, you must raise soft-shelled turtles well. Raising them well is not only about the output, but also about the quality. You must standardize the operation and production according to the relevant national requirements for food quality and hygiene. The author currently advocates low-density disease-free breeding, with the purpose of not using chemical drugs to ensure that the quality of the soft-shelled turtles after breeding is fine, so that the products on the market are not only delicious, but also safe and hygienic. (3) Selling at a good price Generally speaking, good products will not have trouble selling, but you also need to study the market and guide the market so that your products can be launched on the market at the right time. Therefore, in order to sell products at a good price, not only must the products be of good quality and have a brand, but you also need to advertise so that your products can be widely known and become famous in the market.

The breeding technology of soft-shelled turtle

1. Water temperature control

The water temperature of 20℃～30℃ is the best temperature range for the growth of soft-shelled turtles. When the water temperature is higher than 20℃, soft-shelled turtles start to eat, and the amount of food they eat increases with the increase of water temperature. When the water temperature is lower than the optimal temperature, the feed conversion rate will decrease; when the water temperature is higher than the optimal temperature, the feed conversion rate will also decrease due to the increase in activity. Therefore, the water temperature should be kept within the optimal temperature range. Too high or too low will cause feed waste.

2. Feeding

1. Feeding method: Underwater feeding is suitable for the feeding habits of soft-shelled turtles and can speed up their feeding. Feeding with soft pellet feed saves more feed than feeding with block feed.

2. Control of feeding amount. The feeding of turtles is greatly affected by changes in environmental factors. When air temperature, water temperature, or medication is used, the feeding amount should be adjusted taking into account the impact on the turtles. Generally, underwater feeding should be controlled to be completed within 30 minutes.

When turtles eat too much, they grow too fast, which can easily lead to an increase in or overload of their physiological load, causing damage to their internal organs and inducing visceral diseases.

3. Feed selection. Feed costs account for about 40% of the breeding costs. 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 low-quality feed with the comprehensive breeding cost, we can get rid of the misunderstanding of choosing feed based on price alone.

3. Water quality control

Soft-shelled turtles like cleanliness and are afraid of dirt. A good water environment is an important condition for their stable growth. The success or failure of their breeding is determined by how well the water quality is controlled.

1. Oxygenation. The main purpose of oxygenating water is to reduce the content of harmful gases and harmful organic matter in the water. The oxygenation facilities must be kept unobstructed. However, oxygenation should be done within a fixed time period so that the turtles can form a habit and reduce the disturbance caused by oxygenation to the turtles.

2. Reasonable use of microbial preparations. Reasonable use of microbial preparations can greatly save investment in water quality control and other aspects.

3. Draining sewage and changing water. Regular drainage is an effective means of controlling water quality. Changing water is the most direct way to adjust water quality. When changing water, the amount of water to be changed should be determined based on the water quality.

4. Disease Control

Before entering the pond, young turtles should be disinfected and soaked in 2‰ salt water for 30 minutes. Before the turtle weighs 50 grams, beware of fungal diseases. At this stage, the physical fitness of young turtles should be strengthened, and avoiding mechanical damage is the focus of prevention work; when the turtle weighs 50-150 grams, beware of white spot disease, and daily disinfection is mainly based on bromine and chlorine preparations; from 50 grams to adult turtles, beware of furunculosis.
