The spine-breasted frogs grow alongside deep streams in the mountains and call them stone frogs and stone crucibles in Wuning, Jiangxi Province. The current tight market, sales price of 100 yuan to 150 yuan per kilogram. The spiny-breasted frog is a frog with a body weight of 250 g to 500 g. The spiny-breasted frog has a similar shape to the frog's pupa. The individual has a large body, a long tail body fat, and a dark yellow skin color. In recent years, artificial domestication of spiny-breasted frogs has emerged quietly in the mountains. Choose a place
The selection of spiny-breasted frog breeding sites should be based on their biological characteristics, site selection and construction of ecological imitation or use of natural ecological environment. The spiny-breasted frogs often live in fresh water and cool shaded creek brook. In natural conditions, they prey on small terrestrial animals (such as insects, snails, dragonflies, and moths) and prey on small aquatic animals such as shrimp. Crabs, miscellaneous fish, loach, snails. Most of them are mainly foraging at night, and when they are in a quiet environment, they go out for predation during the day. The breeding season is usually from April to September. The male frog climbs on the back of the female frog to hug and mate. The eggs produced are oozing on the quiet water tussocks at the edge of the creek, where they naturally hatch. Water temperature 15 °C ~ 22 °C, 12 days to 15 days can be hatched.èŒèšª Feed on algae in water and eat small animals (such as leeches, ciliates, rotifers, etc.) in water. The spine-breasted frog is a hypothermic animal with a suitable temperature of 18°C ​​to 26°C and an optimum temperature of 24°C to 25°C. In spring and autumn, more food is eaten, and the growth rate is faster. From April to June and from August to September, it is in breeding season. Water temperature below 10 °C, then enter hibernation. Therefore, we must choose fresh water, continuous flow, no pollution; trees are lush and green, quiet environment, rich in insects; shade cool, avoid places with strong light as a farm.
Place construction
After selecting the ideal site, first use fiberglass tiles or brick walls as fences to enclose ecological farms to avoid alien disturbance and escape; then introduce high-quality streams or springs for breeding purposes; Cover shady pergolas, avoid direct sunlight, and ensure proper temperature; plant vine plants and set holes in soil caves to facilitate hiding and hibernation, and create a good ecological environment.
Pond classification
In order to facilitate management, egg production pools, hatching pools, dipping ponds, and baby frog ponds were separately constructed to help them grow normally. Spawning pond: should be built in a place convenient for management and capable of preventing escape and predators. Each area is suitable for 10m2 to 20m2. The embankment is 0.8m high, the water depth is about 0.4m, and the water level in the pool wall is fixed. Overflow holes, laying a layer of cobblestones on the bottom of the pool, the surrounding frogs inhabiting the caves around the embankment to create a simulated ecological environment, promote parental growth and development, improve spawning and fertilization rate; hatching pool: should be selected in the more sunny, can automatically enter the drainage At an area of ​​1 square meter to 2 square meters per area, the pool embankment is 0.5 meters high, and the depth of the pool is 0.1 meters to 0.2 meters. The positioning overflow hole is set and the bottom is covered with pebbles. It is absolutely necessary to ensure that the introduced water is fresh and the pH value is high. 6-8, adequate dissolved oxygen, shade hatching, in order to improve the hatching rate; Dianchi Lake: should be built next to the hatching pool, each area of ​​5 square meters to 8 square meters, pond embankment 0.5 meters high, pool water depth of 0.1 meters, pool The bottom screed is slightly inclined toward the outlet, and the reservoir embankment is set with overflow holes. The inlet and outlet are respectively provided at both ends of the pool and kept under shading conditions. The larvae pool should be close to the spawning pond, with an area of ​​10 square meters. m ~ 15 square meters, 0.8 meters high pool embankment, water depth of 0.2 meters to 0.3 meters, The pool embankment should be gentle so that young frogs can get ashore. Caves should be set up in the water and on the embankment for young frogs to inhabit.
Multicultural management
1. Centralized spawning: From April to May, select individuals with large, healthy, bright skin, 2nd to 3rd ages, spiny-breasted frogs, males at least 0.25 kg, females, 0.2 kg or more, according to the size of the site. , Determine the amount of introduction, laying 5 to 8 pairs per square meter spawning pool is appropriate. Each pair of frogs mating eggs each time about 600 to 1000 tablets, spawning time is mainly from morning to morning, the day do not move the eggs, so as not to affect the hatching. During embryonic development period, it is sensitive to external conditions. When operating, it should be carefully and not flipped. It should be lightly transferred to the hatching pool with net racquet, and 2 eggs to 3 nest eggs per square meter should be hatched.
2. Breeding: The early production of small quail, less activity within three days, no feeding, generally adsorbed on the egg membrane, rely on the nutrition from the yolk to maintain their lives, three days after the increase in activities, began to forage, can be appropriate to vote Feed the cooked egg yolk at the end and gradually feed leeches, algae, and cooked fresh potato. After 10 days of growth and development, the ingestion capacity increased and entered the early growth stage. After 20 days, the digestive function was perfect, and in the middle growth stage, algae and other aquatic plants could be added. After 50 days into the late growth period, the hind legs gradually grew from aquatic to amphibious. After 80 days into the metamorphosis, grow forelimbs, absorb the tail and become a frog.
3. Young frog management: When the young frog is just metamorphosis, the physique is thin, and the ability to adapt to the external environment and predilection is poor. It is a critical stage of survival rate, especially in the first 10 days, it is necessary to regularly feed fresh live baits, each frog About 3 grams a day, such as cockroaches, fly aphids, tenebrio, and so on, and then gradually increase the amount of food for the day. At the same time, it is necessary to prevent predators and other predators, as well as to strengthen overwintering management.
Masks are a kind of sanitary products. Generally, they are worn on the mouth and nose to filter the air entering the mouth and nose to block harmful gases, odors, droplets, viruses and other substances. They are made of gauze or paper.
Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, when working in dust and other polluted environments, wearing masks has a very good effect.
