Introduction to the breeding technology of stone frog, "longevity of food, medicinal acne".

The scientific name of stone frog is thorn chest frog, its big, meat delicious, rich in high protein, a variety of vitamins and minerals, both edible, but also medicinal, is "food longevity, medicinal sores" precious game. So, how do stone frogs grow? The following is an introduction to the breeding technology of stone frogs!

1. Introduction to Stone Frog!

1. What is the name of the stone frog?

The frog is also called stone frog, chicken, pheasant, stone jelly, flying fish, stone scale, toad, frog, stone pit frog, stone chaos, wood locust, etc. It is an amphibian, anura, frog family animal. The adult frog is 123-131mm long, dark brown or brown in color, with warts and small black thorns on its body.

2. Is the stone frog a protected animal?

Wild stone frog is a national second-class protected animal, is a rare product unique to the southern mountainous areas of our country, generally living in clear flowing mountain spring water, police remind, catch wild stone frog is illegal, but, artificial breeding of the second generation, the third generation is food trading.

II. How to breed stone frogs?

1, breeding sites

The breeding farm of stone frog should be selected in quiet and remote mountainous areas. At the same time, the climate in mountainous areas should be warm in winter and cool in summer, the water source should be abundant, the main road of mountain road should be close, the water temperature of mountain water source should be appropriate, the water temperature in summer should be lower than 30℃, and the water temperature in winter should be between 18℃ and 26℃.

2. Frog pond construction

If it is self-propagating and self-supporting, it is necessary to build a frog pond for breeding small tadpoles. The frog pond can be designed as a rectangle of 1m×2m, the water depth is 10-20cm, the bottom of the pond should have a certain slope, and the inner wall should be coated with impermeable coating, which can not only improve the smoothness of the inner wall of the pond, but also avoid the climbing and escape of young frogs.

3. Frog selection

Frog breeding is usually in April spawning, to select a larger individual, healthy body, smooth skin, well-developed, no disability, no damage, to reach sexual maturity of the adult frog, the ratio of male to female is 1:1.

4. Frog breeding pool

The selected frogs are put into a frog pond with a density of 15-20 frogs per square meter. They are generally paired after 9:00 at night. The female frogs oviposit at 4-7:00 in the morning. 300-500 eggs are laid each time. Do not stir within 1 hour of spawning, so as to avoid breaking egg mass and reducing hatching rate.

5. Artificial incubation

Artificial incubation 10-15 days can hatch tadpoles, in the process of hatching, to keep the frog pond temperature appropriate, fresh water quality, dissolved oxygen sufficient, hatched small tadpoles usually adsorbed on the bottom of the pond and egg membrane, less activity, do not feed, three days later more activity, and began to feed.

6. Feed delivery

(1) Tadpoles: 1~4 days after hatching, feed high-protein liquid feed, 5~9 days after hatching, feed powder feed, 10~20 days after hatching, feed nutritious paste juice bait, 21-78 days after hatching, put animal bait; the time is generally once in the morning and evening, feed 1-2 hours after the removal of residual bait and feces in the water; after 50 days, the tadpoles will slowly complete metamorphosis and transform into young frogs.

(2) Young frogs: The food of young frogs is mainly mosquitoes, small insects and insect larvae, etc., but also can be put into fly maggots, mealworms, earthworms and other animal bait.

(3) Adult frog: Adult frog has a wide range of food, insects, centipedes, bee spiders, horse land, snails, clams, shrimps, crabs, miscellaneous fish, sand loach, earthworms, young snakes, small birds, etc. It eats all of them. Generally, it does not need to feed, and it can prey on its own.

7. Daily management

(1) In the incubation period and tadpole period, the water quality should be tested on time. If there is any problem with the water quality, the water should be changed in time. Generally, it should be changed once every 3~4 days, and the routine disinfection should be carried out once every 10~15 days. When the temperature is 20-26℃, the water should be changed once a day, exceeding 37℃, and the water depth should be kept at 10-20 cm.

(2) Check whether the breeding facilities are damaged on time every day, and clean the filtering facilities at the water inlet in time; pay attention to the development status of tadpoles. Different development status, feeding habits and food intake are different, so they should be raised separately; if sick individuals are encountered, isolation treatment should be carried out in time; if dead individuals are found, they should be taken out and treated.

The above is the introduction of stone frog breeding technology, I hope to be useful to everyone.
