Tadpoles come in

I've had tadpoles for years, and from experience, tadpoles are omnivores, high in protein, and rich in sugar he likes. For example, bread, certain microorganisms and algae, egg yolks, earthworm slices, etc.

If your tank is not big and the number of tadpoles is large, you may have to change the water every 1 to 2 days, if the tadpole feeding density is small, you can change the water every 4 to 6 days, or even longer, I once raised tadpoles, because I was busy with the college entrance examination, I didn't care much about other doors, and the result was that the water was not changed for more than ten days, until they became frogs and the water evaporated. From this point of view, the vitality of tadpoles is still very strong.

The last two feet are about six days, the first two feet are slower, about ten days, the specific situation depends on whether your tadpole is developing normally, whether it lacks nutrition, if the development is slow, he changes little every day, and it is even likely to shrink, which means that the stomach will be deflated.

Wild tadpoles grow faster, and at home, unless you completely simulate the wild environment, you can't grow tadpoles in the wild.

It is important to emphasize that if you leave it in a sunny place, it will produce a lot of algae, and if you see tadpoles often floating on the surface to breathe, you need to change the water immediately.

That's it.

There are also varieties of tadpoles, depending on whether you are a frog or a toad, or a larvae of other salamanders or something. Most tadpoles scrape algae with rows of teeth in their mouths, but if there are earthworms, beetles and other small animal carcasses in the water, they will also eat in groups. When I was a child, I saw a flock of tadpoles gnawing on a dead frog.

If you feed them yourself, then just give them bread crumbs, minced meat, small fish and insects, dried noodles, all kinds of insects, aquatic plants.

Pay attention to keep the water clear, otherwise it is easy to die of lack of oxygen.

1.Basically, everyone eats it, and they mainly feed things that contain a lot of starch and protein

2.Look at the feed of the society Generally, there is no fixed time, and the water is mixed and changed * o *

3.This depends on the nutritional situation of the individual, generally from hatching over the first pair of legs

1.Starchy stuff with a lot of protein.

2.Generally, there is no fixed time, and the water is mixed and changed. Sky.

If it is a small tadpole fished directly from the river, then you need to find a relatively large container or fish tank, and also need an oxygen concentrator to provide oxygen to the tadpoles. Then find some aquatic plants and put them in the container, the water temperature is not too high and try to be about 10 degrees, the water quality is a little dirty is not a big problem, because the water is dirty, there is dust, tadpoles can be eaten, of course, you can also throw some bread crumbs as tadpole feed or feed bloodworms (bought in the flower and bird market). If you keep a group of tadpoles, the tadpoles will kill each other, and the number of tadpoles is decreasing every day.

How to feed tadpoles is as follows:

First of all, you prepare a cage frame, similar to the magnification of the gnat's cage is about 10 times, catch live dragonflies, butterflies and other winged insects and put them into feeding, and do not wither to release beetles. If the praying mantis is small, mosquitoes and flies can also be used, but they must be live. Put some grass around the cage so that he will feel safe and feel at ease to hunt.

The specific method is trembling:

1. Prepare a suitable easy-to-raise tadpoles, tadpoles can generally live in any easy place that can be used, they are best to live outdoors, you trap mosquito larvae for tadpoles to eat, and naturally provide a clean aerobic environment. Make sure it lives in a shaded environment all the time, and the right ones are easy to include large aquariums, large bowls, small pools, etc.

2. Lay gravel at the bottom of the container as the base. A large stone is added as a dwelling place and can be used as land when a tadpole transforms into a frog. Put some grass in it and bring the roots, and the tadpoles will lie on it and eat its roots.

Make sure there are no pesticides, pesticides can affect tadpole health.

3. Set a shadow to cover the container if the tadpoles are placed outside. Tadpoles must be able to avoid direct sunlight. Keep about 10 tadpoles in one liter of water, not too many.

4. Keep the water clean, tadpoles need clean, dechlorinated water. Bottled water is also fine, but if the water is from tap water and needs to be left for more than 24 hours, rainwater is the best way to raise tadpoles if there are mosquito larvae in it and there are no chemicals. It is usually recommended to use the source of the water where you catch tadpoles.

Don't use tap water directly, it contains too many chemical components that can affect tadpole health. If you want to use tap water, let it dechlorinate for 24 hours.

5. Change the water for tadpoles regularly, try to change only half of the water once, and keep the pH value relatively stable. Using a hose can reduce the disturbance of tadpoles while also picking up debris from the bottom of the container.

Tadpoles are cultivated as follows:

1. Clear the pool and disinfect. Before the tadpoles are stocked, all kinds of tadpole ponds need to be cleared with quicklime, bleaching powder and other drugs. Quicklime is poured into the pit, water is added to dissolve, and lime water is evenly splashed into the pond while it is hot.

After 3-5 days in the drying pool, new water is filled; The use of bleaching powder should be fully dissolved, immediately splashed throughout the pool, pay attention to bleaching powder has a certain toxicity and corrosiveness, will corrode people's **, Qingtang personnel wear and wear work clothes to operate.

2. Cultivate water quality. Kilograms of well-rotted livestock and poultry fertilizer can be put per square meter as base fertilizer, or fish biofertilizer purchased in fish medicine stores can be used to improve water quality. After cultivating the water quality, sprinkle soybean milk or add bio-fish fertilizer every 3-5 days to ensure that the water quality remains green and has a certain degree of fertility.

3. Tadpole stocking. In the case of an integrated frog breeding pond, about 40,000 tadpoles are generally stocked in each standard pond (about 200 square meters). If tadpoles are cultivated in special ponds, 300-500 newly hatched tadpoles can be stocked per square meter of water surface.

Note that the same tadpole culture pond is good for stocking tadpoles with similar incubation times.

4. Feed feeding. Tadpoles hatch 3 days after the start of feeding, at this time the bait to soybean milk is appropriate, after feeding 7 days to add a small amount of artificial feed, when the tadpole individual reaches the size of soybeans, can be fed with artificial feed. The daily feeding amount is 2%-3% of the tadpole body weight, divided into two feeding in the morning and evening, the normal feeding amount on sunny days, and the appropriate reduction of feeding on rainy days.

1. Tadpoles eat plankton, and it is best to use pond water to raise tadpoles, tap water is not good, and pure water is not good.

2. Tadpoles will kill each other, and when many of them are together, they will secrete some toxins to kill some individuals, so that the rest of the individuals can better survive in a limited environment.

3. The feed of tadpoles should be mainly plant food. Boiled spinach and endage are suitable feeds, but should not be overcooked and the fibre should be removed.

4. Give less feed at the initial stage, gradually increase it later, and regularly feed once a day, not too much, so as not to cause corruption in the feed residual water. Feed residues after each feeding must be removed with a straw and the water must be changed every day or two. The easiest bait is bread, biscuit crumbs or rice grains, or a small amount of cooked egg yolk can be given as animal feed.

5. Tadpoles only need a "bare tank" (that is, an empty basin of water), if you think this is too cruel, you only need to spread a layer of fine sand at the bottom, and then put some aquatic plants with strong vitality, so it is very advanced.

Change the water once every 5 days, and when you change the water, you only need to pour 2 3 water and add the aerated tap water to its original position.

The method of raising tadpoles is to prepare bare tanks and pond water, feed boiled spinach and nest endives, give less feed at the beginning, and gradually increase later, regularly feed once a day, and change the water once every 3 5 days.

The above is a pet-style breeding method, and there is also an intensive breeding model. Standardization should be ensured when building ponds to provide a good environment for the growth and development of tadpoles. The frog pond is designed as a rectangle of 1m 2m, and the inner wall is coated with impermeable paint to improve the smoothness of the inner wall of the pool, so as to avoid damage to tadpoles caused by the cement pool wall, and also to avoid the climbing and escape of young frogs.

There is a certain slope at the bottom of the pool, and the water depth of 3 10 cm is ensured under the condition of a water-to-land ratio of 2 1. And at the bottom of the device 2 4 heating rods to ensure that tadpoles can develop normally in winter and reduce the winter development time. There is an opening at the bottom of the pool, which is connected to the plastic pipe outside the pool to adjust the water level.

A net cover is added to the top of the breeding pond to prevent the invasion of predators.

Morphological characteristics of tadpoles

The aquatic larvae of frogs and toads are short, ovate, with a wide tail, a small mouth, and no outer gills compared to the axolotl larvae, and the inner gills are covered by a gill cover. The tadpole with a lighter body color, a slightly rounded body, a long tail, and a long mouth at the front of the head is a frog. The tadpole with a black body and a shallow tail, an oval shape, a short tail, and a mouth on the ventral surface of the front of the head is a toad.

The tadpoles of toads are black and have a mouth on the ventral surface of the front of the head, while the tadpoles of frogs have a lighter body color and a mouth on the front of the head. The tadpoles of toads are smaller than those of frogs, and the tadpoles of toads are densely packed, and most of them are more scattered than frogs. The body is black, and it has branched gills on both sides of its head, and as it grows, it will slowly grow limbs.
