The spine-breasted frog, commonly known as jelly-chilled or frozen stone, has an adult body weight of 350 grams and is delicious in meat, and has high nutritional value and medicinal value. In the Ming Dynasty, Li Shizhen had described the "spirit and frog in one body, detoxification in one hundred insects" for the spiny-breasted frog. The folks say spiny-breasted frog is a good product of nourishing yin and toxin detoxification. It can treat yin deficiency and labor injuries, stubborn heat problems and diarrhea in children, nocturia, and diarrhea. Intensive artificial breeding of spiny-breasted frogs has a survival rate of 84.8% and a body weight of 2 to 4 grams of young frogs. After 244 days of artificial breeding, the maximum body weight can reach 178 grams, and the feed coefficient is 6.2. At present, Jiangxi, Anhui, Zhejiang and Fujian have aquaculture.
First, the pro-frog cultivation and selection of spiny-breasted frog pro-frog cultivation pool area of ​​12 square meters, 0.8 meters high pool wall, feed table area accounted for 2/5 of the total area, feed water environment outside the total area of ​​3/5, pool The depth of 2.2 meters, the water inlet is set for the inhabitants of the frogs inhabit winter "cave", set the top of the pool escape hood net, summer and winter seasons set up summer and winter shed. The frog feed is mainly based on "Daping No. 2" and concurrently casts ring hair. When the water temperature is between 9 and 22°C from April to November, the food intake per day of the frog is 4% to 10% of the body weight from December to the following year. When the water temperature in March is 2°C～13°C, the food intake of the pro-frog is 2% to 3% of the body weight. The frogs are required to be physically strong, free of injuries, and have bright skin and mucous. They are 11 cm to 13 cm in length and 150 to 250 g in weight. Male frogs require clear thoracic spines, strong forelimbs, and loud vocals. Female frogs require the abdomen to be enlarged and soft, and the fingers touch the abdomen to have a sense of ovum. The ratio of males to females is 1:1, and the density of oxytocins is 2 per square meter.
Second, the oxytocin and management of cement urine production pool area of ​​0.56 square meters to 5 square meters, water depth of 30 centimeters, the pool with a stone into a number of caves, or with a wooden board in the pool side divided into multiple caves. Put a small amount of vascular plants in the pond for frogs to inhabit and spawn. Effort time generally choose around 4 pm. Oxygen formulation: LHRH-A3 and mixed hormones A, B plus 0.7% physiological saline. Female frogs were injected at doses of LHRH-A3200 mg/kg, or mixed hormone A 20 IU/kg, or mixed hormone B 20 IU/kg. Male frog dose is halved. Before the pro-frogs are placed in the urine-producing pool, the urine-producing pool should be cleaned first, and the sludge and egg glue film left on the stones and the pool wall should be washed cleanly, and the stones should be laid out according to the requirements of the urine production pool. After the urine tank is filled with water, it still keeps flowing. In the process of oxytocin, try to avoid disturbing the pro-family at night and check spawning at 7 o'clock in the morning.
Third, the egg-collecting time and method The egg-collecting time chooses before 10 o'clock in the morning that the temperature is lower or after 5 o'clock in the afternoon, collects the egg and collects with the dumpling or the bare hand. Egg collectors use pots, buckets, bowls and other smooth surface tools. At the time of egg collection, the egg membrane is separated from the attachment by freehand, and then the egg is placed in a bowl or bowl filled with water using tweezers. When the eggs are collected, they should be prevented from pulling and damaging the embryo body. Eggs should not be stored too long in the uterus to avoid embryonic body hypoxia. Set the ovary should be placed in a cool place, avoid direct sunlight temperature rise affect embryonic development.
IV. Incubation and Cultivating Cultivation Incubating vascular plants or ferns into the hatchery, and then placing the eggs evenly on it. The amount of eggs laid is 1500 grains/m2~2000 grains/m2 and the water is hatched. During the incubation period, the dirt and egg membrane should be brushed in time to prevent the outlet of the outlet from plugging and causing the loss of eggs. Increase the amount of water in the later stage of incubation. When the embryo develops to the late stage of the primitive intestine, the fertilization rate is calculated by taking 100 eggs, and the hatching rate is calculated when the right temporal dome is closed. After all emerged, the attached plants were removed and the waterproof quality deteriorated.
When the first hatchling is about 15 millimeters in length, the body is weak and difficult to move and is kept in the hatchery. On the third day of the film, the cooked egg yolks were fed, once in the morning and one in the evening, and they were fed for 3 days with 1 capsule per 2000 pigs per day. Stop for 30 seconds when feeding. Put the egg yolk in the gauze, squeeze the egg yolk into a paste by hand and rinse it in a bowl until the egg yolk becomes a tiny suspended particle. Put the egg yolk into the pool with your finger and feed it from 2 to 3 times. From the fourth day Feed the cooked loach or scutellaria or rice and feed it at about 4% of body weight. As the growth of the earthworm gradually increases the feeding amount, it is timed, fixed, and quantified at the time of feeding. Every time you feed, collect excess food and adjust the amount and type of feeding. After 30 days, the pupa had a total length of about 35 mm, and its ability to feed was high. At this time, the survival rate of the pupa was checked and fed in separate ponds. The stocking density was 300 fish/m2 to 350 fish/m2, and the ration was increased to the weight. About 10%. After 60 days, the length of the cockroach was about 60 mm. The survival rate was checked again, and the feeding rate was divided into two groups. The stocking density was 200 pigs per square meter. After long-limbed limbs, plates, tables, and collecting frog boxes for abnormal frogs to land were placed in the pool, and nets were set on the pool to escape, or long-living maggots were collected in a young frog pond for feeding. .
