What water quality is needed to raise soft shelled turtles, how to feed soft shelled turtles at home

Water is the space that soft-shelled turtles rely on for survival, and they mainly rely on water to provide various substances that support life-sustaining activities. The quality and state of the water environment directly affects all stages of its life and all aspects of life.

The water source is preferably unpolluted river water, lake water or large reservoir water. This kind of water has a high amount of dissolved oxygen, good water quality, and is suitable for the growth of soft-shelled turtles. When using well water, the well water can be pumped into a reservoir to allow it to be naturally aerated and heated, and it can also be used as a water source after physical and chemical treatment.

In short, it should be ensured that the indicators of water quality meet the requirements of the freshwater aquaculture water source in the industry standard of the Ministry of Agriculture "Pollution-free Food Freshwater Aquaculture Water Quality" (NY5051-2001), so as to meet the demand for water quality of soft-shelled turtle to the greatest extent, so that soft-shelled turtle can grow rapidly under relatively superior and safe conditions.

The water body whose water quality meets the needs of healthy aquaculture must not only have sufficient water volume, but also have water quality with physical and chemical properties suitable for its physiological characteristics.

Dissolved oxygen in dissolved oxygen water is produced by the atmosphere on the one hand, and by aquatic plants during photosynthesis on the other hand. When water flows, the contact surface with air is large, which can increase the rate of oxygen dissolution in the air. However, ponds are small and flow, and there is usually very little oxygen dissolved in the air.

Dissolved oxygen in ponds is mainly used for photosynthesis of aquatic plants. Soft-shelled turtles live in the water, and sufficient dissolved oxygen in the water is particularly important to the life of soft-shelled turtles, and the soft-shelled turtles crawl at the bottom of the pond, and the oxygen difference between the upper and lower levels of the pool water is particularly sensitive to them.

Water temperatureWater temperature is one of the important environmental conditions for all aquatic animals, including soft-shelled turtles. Soft-shelled turtles are particularly sensitive to water temperature, and soft-shelled turtles have "three fears", namely fear of cold, heat, and noise, of which the first two fears are related to water temperature. Studies have shown that the growth temperature range of soft-shelled turtle is 20 33, and the optimal temperature range is 30 32.

When the water temperature drops below 15, the soft-shelled turtle stops feeding. In summer, when the water temperature exceeds 35, soft-shelled turtles should look for a place without sun exposure to cool off.

pH and other pH can not only indicate the concentration of hydrogen ions, but also indirectly indicate carbon dioxide, alkalinity, dissolved oxygen, dissolved salts, etc. in water. Generally speaking, the more carbon dioxide in the pool, the lower the pH, the higher the carbon dioxide, the pH is too low is not conducive to the growth of soft-shelled turtles, and the acidic environment makes the pH of soft-shelled turtle blood decrease, reducing its oxygen-carrying capacity.

Organic matterOrganic matter mainly includes photosynthesis products, phytoplankton extracellular products, aquatic excretory wastes, biological debris and microorganisms. In soft-shelled turtle farming, it can be used as food for soft-shelled turtle bait organisms. However, when the number is too large, it will spoil the water quality and affect the growth of soft-shelled turtles.

- As I learned in nature class, you should use water related to plants, such as water for washing vegetables or rice. By the way, the water that has finished raising fish can plant plants (everything that has to do with animals can be planted (it seems to include excrement ==)).

<> at home, the soft-shelled turtle can be fed food twice a day, and the amount of feeding each time is appropriate to eat the soft-shelled turtle in about 30 minutes. If it is a 1-year-old soft-shelled turtle, about 20-30 soft-shelled turtles per square meter are stocked, and if it is a 2-year-old soft-shelled turtle, 7-20 soft-shelled turtles are stocked per square meter. Soft-shelled turtle is an ectothermic animal, and its food intake is mainly related to water temperature.

1. How to feed soft-shelled turtles at home

1. At home, soft-shelled turtles can be fed food twice a day, and the amount of feeding each time is mainly based on the standard of eating in about 30 minutes. The food provided to soft-shelled turtles can choose tadpoles, small shrimp, small fish, egg yolks, rice, noodles, mollusks, vegetables, fruits, grains, etc., and you must pay attention to ensure the freshness of the food.

2. When breeding soft-shelled turtles, it should be noted that if it is a 1-year-old soft-shelled turtle, about 20-30 can be stocked per square meter; If it is a 2-year-old soft-shelled turtle, 7-20 can be stocked per square meter; If it is a 3-year-old soft-shelled turtle, it is stocked with 3-5 soft-shelled turtles per square meter, and if it is a 4-5-year-old soft-shelled turtle, it is stocked with 1-3 soft-shelled turtles per square meter. If it is fed dry bait, the amount of feed must be 2-5% of the body weight of the soft-shelled turtle.

3. Soft-shelled turtle belongs to ectotherms, its feeding has a certain relationship with water temperature, when the water temperature is 20-32 °C, the amount of food is relatively large, when it is lower than 20 °C, the amount of food will decrease, and it will not eat when it is lower than 15 °C. When the water temperature exceeds 33°C in summer, its appetite will decrease, and it will hide under the water or in the shade during the day to escape the heat, and at night it will go ashore in search of food; In winter, they dive underwater, do not eat or move, and hibernate until the end of the hibernation period in March of the following year.

Second, what are the requirements for water quality of soft-shelled turtles?

1. The soft-shelled turtle has relatively high requirements for water quality, and if the water is not changed for a long time during individual breeding, the water quality will become turbid and yellow, so that the soft-shelled turtle will die. Generally, the clean water must be replaced once every 3-4 days, and the clean water can be used with lake water or well water, or tap water can be left for 1-2 days before use. The water body of aquaculture should not only ensure sufficient water quantity, but also have the physical and chemical properties of water quality suitable for its physiological characteristics.

2. When breeding soft-shelled turtles, the water level must be controlled, generally about 40cm, if you feel that the water level is too low, you can also increase it appropriately, but not more than 1 meter. The soft-shelled turtle has certain requirements for water depth, and also has temperature, and the water temperature must be controlled at about 20 °C, which is more conducive to its growth.

3. When raising soft-shelled turtles, you must plant aquatic plants in the fish tank, so as to provide a place for them to take refuge. In winter, the turtle will enter a dormant state, and the ambient temperature must be controlled above 5 °C to avoid the soft-shelled turtle from freezing to death. In the spring, be sure to feed the soft-shelled turtle medicine to avoid contracting diseases.

The soft-shelled turtle has a strong ability to survive, as long as there is an appropriate amount of water and food in the bucket, there is no problem in living for a few months, and the soft-shelled turtle will not die if it does not eat for more than 3 months, because the soft-shelled turtle is hungry and gluttonous, and can rely on its own accumulated nutrients to maintain life, but in the case of no water, it can only live for about 3-4 days.

If you breed soft-shelled turtles in the summer, you can keep them directly in a basin or bucket, but be careful not to have too much water, as long as it does not pass the back of the soft-shelled turtle. Because the soft-shelled turtle is more afraid of dirt, heat, and mosquitoes, it should be allowed to bask in the sun for about 1-2 hours every week, which can kill the parasites on the body.

Precautions for soft-shelled turtle farming.

1, to build a pond to choose a quiet environment, no wind to the sun, convenient drainage and irrigation pond for breeding, if it is self-breeding, self-breeding, self-raising soft-shelled turtle farms to carry out the construction of 5 kinds of breeding ponds, respectively, the new soft-shelled turtle pond, juvenile soft-shelled turtle pond, juvenile soft-shelled turtle pond, 3-year-old soft-shelled turtle pond, adult soft-shelled turtle pond.

2. The soil of the pond is best to be clay or loam, if there is no sandy soil at the bottom of the pond, it is necessary to mix a part of the sandy soil, and build a drying platform and bait feeding table on the edge of the breeding pond to provide a place for soft-shelled turtles to dry their backs and ingest food, and build an anti-escape wall with a height of 1m with asbestos tiles and bricks around the breeding pond.

Soft-shelled turtles are ectotherms, generally amphibious, using their lungs to breathe, and mainly live in lakes, ponds, reservoirs, triangular bays and slow-flowing rivers.

With the development of the medicinal value and edible value of soft-shelled turtles, the artificially cultivated soft-shelled turtles have also increased, and many farmers have cultivated soft-shelled turtles. The living habits of soft-shelled turtles can be summarized as "three joys and three fears", that is, they like to be quiet and afraid of surprise, they like the sun and are afraid of the wind, and they like to be clean and afraid of dirty. At present, there are mainly soft-shelled turtles such as Chinese soft-shelled turtle, Shanrui soft-shelled turtle, spotted soft-shelled turtle, and turtle turtle in China.

Among them, the Chinese soft-shelled turtle is the most common. So what conditions are needed for soft-shelled turtle farming? How to manage it?

Breeding conditions of soft-shelled turtles, pond conditions. The area of the pond is generally about 5 acres, the slope of the pond is 1 2, the bottom of the pond is flat, the thickness of the silt is about 25 cm, and the water depth is meters. Water source requirements:

The pond water source should be sufficient, the water quality should be good, pollution-free, in line with the water standard for fish farming, pH value 7, dissolved oxygen 5 milliliters or more.

Anti-escape facilities: The anti-escape wall is built around the pond, the wall is 40 cm high, the top of the wall is 10 cm inward, and the inner wall is smooth to prevent the turtle from escaping and the invasion of enemies.

Ponds: According to the growth stage of the soft-shelled turtles, the ponds are divided and disinfected with quicklime. Stocking:

Before stocking, bathe the seedlings with 20 mg l of potassium permanganate solution for 20 min. Feeding: The proportion of fresh feed is 10%-40% of the bait fed every day, and the bait should be eaten within hours by soft-shelled turtles.

1. How to raise soft-shelled turtles

1. Pond treatment.

1) Turtle pond: choose to build a quiet plot, an area of 1 acre, about 1 acre of water depth, set up a spawning site on the ridge of the pond on the sunny side, and set up an escape wall 50-80cm higher than the ridge of the pond around the pond.

4) Turtle pool: an area of 1-2 acres, about the depth of the water, build an anti-escape wall around it, and build an island in the pond ** at the same time, for the soft-shelled turtle to dry its back and move.

5) Before stocking, 125kg of quicklime water needs to be used to splash the whole pond for disinfection per mu of pond.

2. Stocking. (1) Before stocking, seedlings need to be bathed with 20mg L potassium permanganate solution for about 20 minutes.

2) 10-15 juvenile soft-shelled soft-shelled soft-shelled soft-shell

3. Feeding. (1) Raising soft-shelled turtles is mainly based on compound feed, fresh fish, shrimp, snails, earthworms, poultry offal and other animal feeds, pumpkin, apples, watermelon skins, vegetables and other plant feeds.

2) Before feeding, disinfect the food by bathing with a 20 mg l solution of potassium permanganate.

3) The proportion of fresh feed should be 10-40% of the daily feeding; It is advisable to feed the soft-shelled turtle within an hour.

4. Management. (1) Regularly change the water, and the amount of water exchanged each time does not exceed one-third of the total water volume.

2) The transparency of the water body is controlled at about 30cm.

3) Do a good job in the prevention and control of white spot disease, rot disease, red neck disease, red bottom plate disease and other diseases.

Second, can soft-shelled turtles keep in the water all the time?

1. Soft-shelled turtles cannot be kept in the water all the time, and it is best to build a platform in the pool for them to rest outside the water.

2. Soft-shelled turtles mainly rely on the lungs for breathing during growth, and generally need to surface for ventilation every once in a while; When the water temperature drops below 15, the soft-shelled turtle will dive into the silt at the bottom of the pond to hibernate and rely on auxiliary respiratory organs such as gill tissues in the throat to breathe.
