On the issue of stone frog breeding, what should we pay attention to in the breeding of stone frogs?

Stone frog breeding seems to be easy, but in fact, the pass rate is not high, which often makes beginners suffer. In recent years, many attempts have been made at the level of human feeding of stone frogs in the southern region, and the key is that the growth standards of stone frogs are very unique, and the demand for the natural environment is high, and it is difficult to raise them successfully if their growth rules are not clarified. The following is a list of some rules and experiences summarized in the planting process of a farm in recent years.

Stone frogs belong to the flowing water lifestyle. It often inhabits the slower flow of streams in mountainous areas or in the deep water depressions of flowing streams, and the vegetation on both sides of the stream is rich and colorful. They rarely leave the sea, and their body color is often consistent with the natural environment in which they live.

When laying eggs, females and males must lay their eggs in the stream of the impact of flowing water, and when breeding, the males are strong and silently waiting for the females, and with the spines of the abdominal cavity to enhance the contact inhibition of the males, so that they are not washed away by the current.

The stone frog has an internal vocal sac, the pronunciation is low and loud, the male chirps "coo", and the female worm corresponds to the "click" sound. Stone frogs have the habit of living in groups and looking for food at night, usually a few or dozens of them are piled together to cohabit in one place, in the quiet and suitable conditions, the stone frog also comes out of the burrow to seek food during the day, and the evening is the mature period of activity. Stone frogs are good at jumping and climbing, their usual activities are poor and stable, and they have personal behaviors such as chirping and hugging each other during the breeding and maturity period.

Stone frogs like to eat active animals, generally do not eat dead or untouched food, in a certain situation, the carnivorous nature of stone frogs is general, in addition to insects, large centipedes, spiders, horses, small turtles, snails, clams, loaches, shrimp but also prey on crabs, trash fish, loach fish, young snakes and small and medium-sized birds. Stone frogs in different areas have different carnivorous feeding properties due to different bait that can be given by the natural environment. Stone frogs generally swallow up to 9% of their weight in nature, sometimes do.

Tadpoles: Stone frog tadpoles sometimes feed on aquatic plants in streams or underwater sponges, and they use their horn teeth to gnaw off the soft plant tissues and eat them. Tadpoles gnaw off plant-based microcyclic algae, filamentous algae, sponges, mosses, diatom mud, dinoflagellates, goldfish algae and green plant debris; Animals include paramecium, flagellates, daphnia, rotifers, etc.

Some people have also found stone frogs feeding on epiphytes that lift rocks in the water, zooplankton in the sea, leaves of green plants that fall into the water, or animal remains in streams. Sometimes they also eat dead kinds.

It is necessary to select excellent varieties for breeding, to prevent pests and diseases, to ensure that the environment is good enough, and to ensure that the water quality is good enough.

When breeding stone frogs, you should choose a large place, but also choose some clean water sources, you can also add some silt to the water source, do a good job of shading and do a good job of preventing escape, because stone frogs are amphibians, so you should also place some clean boards so that you can breed good stone frogs.

First of all, it is necessary to pay attention to the clarity of the water, and we must replace the water resources in time, and it is necessary to ensure the oxygen of the water, and then in the process of breeding, we also need to place some aquatic plants.

Stone frog is an amphibian tailless frog family, its meat is delicious, nutritious, known as the "king of frogs", it is the edible frog with the highest nutritional composition and medicinal health value in China's traditional recipes, it has always been the tribute of the royal court, and because of its good market, many people want to breed stone frogs. So how are stone frogs farmed? The following is the breeding method and nutritional value of stone frog that I have introduced to you, I hope it can help you.

How to breed stone frogs

1. Frog selection: Frog is the basis of artificial reproduction, after hibernation, before spring multiplication, the adult frog is comprehensively inspected and classified, and the individual is larger, strong, smooth, well-developed, no disability, no damage, and the adult frog that has reached sexual maturity is reserved for seeding.

2. Breeding frogs: Stone frogs should be strengthened before hibernation to make them thick and strong, and should be kept fed when the temperature reaches more than 12 in winter, so as to reduce the consumption of energy in the body in winter and maintain the growth of stone frogs and the good development of gonads.

3. Breeding and egg laying: stone frogs are usually bred in April, the ratio of male to female is 1:1, the stocking density is 15 20 per square meter, generally after 9 o'clock at night, the female frog ovulates at 4 7 o'clock in the morning, and generally lays 300 500 eggs each time.

4. Artificial incubation: the fertilized eggs of stone frogs begin to develop to the stage of tadpole hatching, which is very sensitive to external changes, and the whole incubation process should meet the technical requirements such as appropriate temperature, no pollution of water quality, disinfection of frog eggs, and aeration of the hatching pool.

5. Tadpole feeding: stone frogs under artificial breeding conditions, female frogs lay eggs after artificial incubation for 10 15 days to hatch tadpoles, small tadpoles are usually adsorbed on the bottom of the pond and egg membranes after hatching, rarely active, and do not forage, to three days after the activity increases and begins to forage.

6. Young frog feeding: young frog feed has fly maggots, mealworms, earthworms, etc., take measures to avoid light during the day, the water depth is 10 15 cm, the water quality is the same as the tadpole period, the water is changed depending on the water temperature and water quality, and the water is changed once a day at 20 26 o'clock.

7. Safe wintering: tadpole wintering can be carried out indoors, with a water depth of about 20 cm, and anti-freezing measures such as constant running water, frog pond covering, and heat preservation are adopted. The hibernation depth of the young frog is about 15 cm and there is a certain amount of land, and there should be thermal insulation and anti-freezing measures in case of low temperature and freezing weather.

What are the nutritional values of stone frogs

1. Stone frog is rich in natural glutamate, the meat quality is extremely fresh, the protein content is also very high, and the fat is low, which is the most ideal yin and heat dissipating delicious mountain treasures.

2. Stone frogs are rich in high protein, a variety of vitamins and minerals, such as vitamins A, B1, B2, C and niacin, of which proline and alanine are particularly rich.

3. Stone frog contains 17 kinds of amino acids and rich glucose, iron, phosphorus and vitamins A and B and other more than 10 kinds of nutrients needed by the human body.

4. There are many kinds of mineral elements in stone frogs, which are rich in a variety of trace elements necessary for human metabolism, and have high nutritional, health care and medicinal value.

1. In order to ensure economic benefits, the intensive breeding mode is generally adopted, so the standardization should be ensured when building the pond to provide a good environment for the growth and development of tadpoles. The inner wall of the frog pond is coated with impermeable paint to improve the smoothness of the inner wall of the pond, so as to avoid damage to the tadpoles caused by the cement pool wall;

2. At the same time, it is advisable to be close to the main road of the mountain road, which is suitable for the transportation of the thorn-breasted frog breeding process, which is objectively easy to manage, and the needs of advanced technology and equipment can be carried out with convenient transportation;

3. The growth of the spiny-breasted frog has higher requirements for the water source, so the abundant water source in the mountainous area is another important influencing factor for the selection of breeding sites of the spiny-breasted frog, the water source should be mainly mountain stream water, cold spring water and groundwater, the water source is abundant, the water temperature should be moderate, and He Wang is suitable for the needs of the growth of the spiny-breasted frog;

4. In order to realize the discharge of sewage from the growth process of the spiny-breasted frog, the construction of water conservancy facilities should be improved to facilitate the transportation and irrigation of water sources.

5. Choose a suitable breeding site, which is mainly in quiet and remote mountainous areas, and the mountainous climate is warm in winter and cool in summer, which is suitable for the breeding of spiny-breasted frogs in this area.
