Price and breeding method of stone frog seedlings

Stone frog is the most ideal delicious mountain for nourishing yin and relieving fever. it is known as the king of frogs and has always been a tribute to the royal court. Now it has become one of the main food and breeding frogs because of its fast growth, large size and good market. Let's take a look at the price and breeding methods of stone frog seedlings.

How much is a stone frog seedling?

The price of stone frog seedlings is about 0.2 to 0.5 yuan, but it varies according to the quality, quantity and market of frog seedlings. Stone frogs lay 250 eggs at a time and 1000 eggs at 1 breeding season. It takes 20 days for eggs to hatch at 16 ℃ and 7 days for 26 ℃. Tadpoles that hatch early can complete metamorphosis in the same year after 4 to 5 months of growth, while tadpoles in middle and late stages need to overwintering in May-June of the following year. Young frogs need about 2 years to reach sexual maturity after landing.

Construction of stone frog culture pond

1. Frog planting pond: the area is generally 410m2, the height of the pond is 0.8m, the water depth of the pond is 0.1m and 0.15m, the ratio of water to land area in the pond is 3 ∶ 1 and there are perched stone caves, the bottom of the pond is covered with large pebbles, the light is dark, and the humidity is maintained at 80%.

2. Incubator: the area is 1 square meter, the height of the pool is 0.5m, the water depth is 15cm and 20cm, the water quality is fresh, pH6~8, and contains enough oxygen. You can also use a large oval washbasin instead.

3. Tadpole pond: the area is 380 square meters, the height is 0.8m, the water depth is 310cm, pH6~7, the ratio of water to land is 2 ∶ 1, need shading to raise, it is better to raise a group of tadpoles of the same specification in each pond.

4, the young frog pond: the area is 4 square meters, the pond height is 0.8m, the water depth is generally 10cm 15cm, the ratio of water to land is 2 ∶ 1, the pond is paved with pebbles of 3cm to 5cm, the water quality is good, and the pH value is 67.5.

Culture methods of stone frog

1. Frog selection: breeding frogs are the basis of artificial reproduction. Adult frogs are comprehensively examined and classified after hibernation and before spring breeding. Adult frogs with strong body, smooth skin, good development, no disability, no damage and sexual maturity are reserved for breeding.

2. Breeding of stone frogs: the stone frogs selected for breeding should be strengthened to make their fat thick and strong before hibernation, and should be kept fed when the temperature is above 12 ℃ in winter, so as to reduce the energy consumption in winter and maintain the growth and gonadal development of stone frogs.

3. Mating and spawning: stone frogs are usually mated in April, with a female-to-male ratio of 1:1, with a stocking density of 1520 eggs per square meter, usually cuddled after 9 o'clock at night. Female frogs ovulate at 4: 7 in the morning, usually laying 300 eggs at a time.

4. Artificial hatching: the fertilized eggs of stone frogs begin to develop to the stage of tadpole hatching, which is very sensitive to external changes. during the whole hatching process, the technical requirements should be met, such as suitable temperature, no pollution of water quality, disinfection of frog eggs, increasing oxygen in the incubator and so on.

5. Tadpole feeding: under the condition of artificial feeding, female frogs hatch tadpoles after spawning for 10-15 days. Tadpoles usually adsorb on the bottom of the pool and egg membrane after hatching, rarely move and do not look for food. After three days, the activity increased and began to look for food.

6. Feeding of young frogs: young frogs are fed with maggots, yellow powder worms, earthworms, etc. Measures are taken to avoid light during the day, the water depth is 10-15 cm, and the water quality is the same as that in the tadpole period. The water is changed once a day at 20-26 ℃.

7. Safe overwintering: tadpoles can overwinter indoors with a water depth of about 20 centimeters, using anti-freezing measures such as regular running water, frog pond cover, heat preservation and so on. The hibernating water depth of young frogs is about 15 cm and leaves some land, so there should be heat preservation and anti-freezing measures in case of low temperature and freezing weather.
