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, the economic value: spiny-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 feast. Its food value is far 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-breasted frog has the properties of flatness, sweetness, intrinsic heart, liver, and lungs. It has the effects of nourishing yin and reducing anger, clearing the heart and regulating the lungs, and strengthening the liver and kidney. It has some assistance in the treatment of hoarding, weakness after illness, 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, rational protection and development, in order to meet the growing needs of people. Second, the morphological characteristics: spine-breasted frog shaped black spot frog, but stronger than black spot frog stout meat fat. 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-breasted frog not only has a beak on the back, but also has a small round beak on the head, limbs, back, and body side. There are scattered small black spines on the spine. 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. The female ventral skin is smooth and there are no black moles. The head of the spiny-breasted frog is broad and flat, with a round snout and a prominent prominence in the lower jaw. The snout is not very clear, and the distance between the two nostrils is almost equal to the distance between the two eyes. Third, living habits: spiny-breasted frogs are distributed in the southern provinces of China, often inhabiting jungles and canyons, streams, grottoes, and rocky ravines with an altitude of 150 to 1,000 meters. They are nocturnal, and enjoy hiying on water. 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, cockroaches, beetles, long-horned cows, ants, cockroaches 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 ooplasm is thick and sticky. Many eggs stick together and float in water or objects attached to the 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. Fourth, rearing pool construction: artificial breeding of spiny-breasted frogs must be selected in the pollution-free water, springs, groundwater flow through the place, to simulate wild wild spiny frog's wild ecological environment to build a breeding pond. The rearing pond is best in the high mountainous area of ​​200-800 meters above sea level, which is conducive to wintering in summer. For example, in the low-lying plain high-temperature area, breeding spiny-breasted frogs can guide deep well water, cold pond water or deep hole water into the pool, and make the breeding environmental protection quiet, shaded, cool, small changes in temperature, humidity. Therefore, there must be shady equipment in the farm, and there are clean water sources near the breeding pond. 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 kg of bean curd residue. In the evening, they are released once a day. After 10 days, they are baited twice a day. At this time, bean curd residue can be used. After 20 days, feeding 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 of female frogs, spawning ponds should be set up in Sheung Shui, 300 to 1000 frogs should be placed, and raised for 10 to 15 days, and then transferred to cages for hatching and hatching of normally cultivated summer fish species. Nesting box can be placed 20 to 30 groups of species of frogs, small quantities as long as the male and female frogs in 1:1 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 attachment to the eggs. The water temperature will be 10°C to 16°C. A day or so will be mated, and eggs will be laid in 10 days. The water depth of the hatching pool is 15cm. When the water temperature is 10°C～16°C, 4～5 eggs are placed per square meter of water. If the temperature is normal, about 100 days, hatching will occur.
