The spine-breasted frog, also known as the spiny frog, stone frog, sarcophagus and stone chicken, belongs to the frog family of the amphibians.
First, economic value: The spine-breasted frog is a large group of wild frogs. It is a large and fleshy meat with a lot of nutrients such as chicken. The frog meat contains many nutrients such as protein, glucose, amino acids, iron, phosphorus and vitamins, and its fat content is very low. It has always been the best food in the South China banquet. Its food value is much higher than that of bullfrogs, and it is hailed as a "king of the white frog" by foreign foodies. The spiny-breasted frog meat can be used medicinally; it has nourishing and strengthening effect. The spine and breast frog has the properties of flatness, sweetness, intrinsic heart, liver and lung, and has the functions of nourishing yin and reducing anger, clearing the heart and regulating lung, strengthening liver and kidney, and assisting in the treatment of hoarding, weakness after illness, upset thirst, etc. Efficacy.
In recent years, due to the indiscriminate use of pesticides and excessive use of pesticides to pollute the water quality, the ecological environment has continuously deteriorated, resulting in a decline in wild spines and frogs. Vigorously develop artificial breeding and rational protection and development to meet people’s growing needs.
Second, the morphological characteristics: spine-breasted frog shaped black spot frog, but thicker than fat black frog. Adult frogs are generally 10 to 13 cm in length, 150 to 250 g in body weight, and up to 400 g in size, with heads wider than heads. The skin is rough, the back skin is dark gray and there are many blemishes. Males have long, narrow, long slugs on their backs and small black slugs on their backs. The spine and breast frogs have not only back spasms, but also small round buns on the head, limbs, back, and body sides. There are also scattered black spines on the bracts. The male's chest has a scattered horny black broiler, which is called the spiny-breasted frog. Male forelimbs are thick, with rounded fingers and slightly enlarged. The first finger is particularly thick at the base. Female ventral skin is smooth and there are no black spots. The head of the spiny-breasted frog is wide and flat. It has a round nose and protrudes from the lower jaw. The kiss edge is not very clear. The distance between the two nostrils is almost equal to the distance between the two eyes.
3. Living habits: The spine-breasted frogs are distributed in the southern provinces of China. They often inhabit jungle gorges, rivers, grottoes, and rock valleys with an elevation of 150 to 1,000 meters. The sun. Every year from the end of November to the middle of April the following year is the period of hibernation. It grows fastest at temperatures of 25°C to 30°C and water temperatures of 20°C to 27°C. It mainly eats a variety of insects, such as stink bugs, dragonflies, chafers, long-horned cattle, ants, beetles and shrimps, loach and tender grass roots.
From May to September, it is the breeding season of spiny-breasted frogs, which spawn three times a year. Female frogs produce 500-1000 eggs a year. They are usually produced on the roots or rocks below waterfalls, and sometimes on rocks or aquatic plants. The eggs are large, with an average diameter of 4 mm and a maximum of 5 mm. The ooplasms are thick and sticky. Many eggs stick together and float in water or on objects attached to water. The fertilized eggs are slow to develop under natural conditions, and hatching begins after 22 days. The dragonfly lives in a large stone crevice or gravel pile in a mountain stream puddle.
IV. Pond construction: Artificial breeding of spiny-breasted frogs must be conducted in a place where unpolluted water, spring water, and groundwater flow through, and the wild ecological environment of wild spiny-breasted frogs can be used to build a breeding pond. The rearing pond is best in the high mountainous area with an altitude of 200 to 800 meters above sea level, which is conducive to wintering in summer. For example, breeding spiny-breasted frogs in high-altitude plains with low altitude can guide deep wells, cold ponds, or deep-seated water into the pool, and make the breeding and environmental protection quiet, shaded, cool, with small temperature changes, and high humidity. Therefore, there must be shade equipment in the farms, and clean water sources near the breeding ponds.
Fifth, feeding and management: Small quail 5-8 days to start feeding. The 100 species of frogs can be mixed with 5 eggs or duck eggs and 5 to 7.5 kilograms of bean curd residue. In the evening, they should be released once a day. After 10 days, they should be baited twice a day. At this time, rubbish residue can be used. After 20 days, feeding is performed. Feed, the amount of food to eat every day is better. In summer, the temperature in the pool should not exceed 32°C, and the water temperature should be kept below 28°C. According to the physiological characteristics of frog lung and skin respiration, relative humidity must be maintained at about 80%. In order to provide enough feed for spiny-breasted frogs, fly maggots should be combined.
6. Breeding: The reproduction rate of spiny-breasted frogs is very high, 5-8 times per year for the spawning season. Before spawning by females, spawning ponds should be set up in Sheung Shui, 300 to 1000 frogs should be placed, and raised for 10 to 15 days, then transferred to cages that normally raise summer fish species for spawning and hatching. Nesting box can be placed 20 to 30 groups of species of frogs, small quantities as long as the male and female frogs by 1:1 on the water depth of 15 cm, the size of the desktop size of the pool can be. In the pond, straw or wheat straw should be placed as the attachments of eggs. The water temperature will be between 10°C and 16°C. It will be mated in 1 day and will spawn in 10 days. The water depth in the hatching pool is 15 cm. When the water temperature is between 10°C and 16°C, 4 to 5 pellets of eggs are delivered per square meter of water. If the temperature is normal for about 100 days, the hatchets will hatch.
