What is the prospect of toad breeding? The technology of efficient cultivation of toad in rice field is attached.

Toad is a valuable amphibian and reptile of food and medicine. Toad's shell toad clothing and serous collected and processed by retroauricular gland are valuable traditional Chinese medicine. So what are the prospects for toad breeding? What are the breeding techniques for efficient cultivation of toads in paddy fields?

I. the prospect of toad breeding

With the decrease of wild resources, it is difficult to see a large number of toads in the wild, and our country has severely cracked down on the capture of wild toads, and there are also cases in which they have been convicted. After 2017, the market demand for toad venom is also increasing, the price has been rising, now the price has risen from 3000 yuan per jin in previous years to 5000 yuan per kilogram. According to industry insiders, China's current acquisition of toad venom can only reach 23% of the demand, there is still a large market vacancy, and the prospect of toad breeding is still considerable.

Collecting toad clothes: one live toad can take toad clothes from April to October every year. The working time is 6-7 months in the northeast and 7-9 months in the south. At least two toads can shed their clothes every month. 2000 toads can produce 24000 toad clothes in 6 months. Calculated according to the unit weight of 0.3g of toad clothes, it can produce 7.2kg of toad clothes. According to the clothing rate of 80%, it can produce 5.76kg of whole toad clothes at a conservative price of 10, 000 yuan per kilogram, with a value of 57600 yuan. The production of thin clothes is 1.44kg, which is worth 8640 yuan at a conservative price of 6000yuan / kg, that is, 2000 toads can make a profit of 66240 yuan by collecting toad clothes in one year.

Collect toad venom: a live toad can be taken from April to October every year. The working time is 6-7 months in the northeast and 7-9 months in the south. Toad is collected twice a month. 2000 toads can produce 1 kg of toad a month. According to the conservative price of 3000 yuan, 6 kilograms of toad can be produced in 6 months, creating a value of 18000 yuan. If the local wild toad is large, buy it in the local surrounding area or find someone to catch the toad yourself. If there is less investment, the benefit will be higher.

2. Techniques for efficient culture of toads in paddy fields

The field pool setting chooses the field which is more secluded and convenient for drainage and irrigation. The paddy field is surrounded by a 0.8-meter-high nylon net with a width of 1.5 meters, which is convenient for the toad to get ashore, and a net is set up at the inlet and outlet to prevent the toad from escaping. A small pond is dug only on one side of the ridge of the rice field to raise tadpoles. The pond area is not less than 1 big 6 of the total area. If the aquaculture rice field is too large, several small ponds can be set up, the water depth of the pond is 40 cm, and a water injection pipe with a diameter of 1 cm is set up over the pond, and a water outlet is set up on any side of the ridge, surrounded by polypropylene mesh. The mesh should be 60 per square centimeter.

When tadpoles are released, the small ponds are dry cleaned with 15kg of quicklime, water is injected 7 days later, 100kg of fermented organic fertilizer is added to the pond, and tadpoles are put into the pond 5 days later. Harmless, robust and neat tadpoles are selected for stocking. After 1.5% salt water disinfection, 6000 ~ 8000 tails per mu of rice fields are released, and the temperature is not lower than 20%.

Toad ponds manage small ponds not only to ensure micro-running water, but also to keep the water quality from deteriorating under the action of residual bait. When feeding, it is appropriate to feed a small amount for many times, and feed it with floating powder until it is abnormal. After the abnormal end of the toad, a round bait platform with a wire mesh at the bottom was set up in the middle of the pond, and the live bait (earthworms, maggots, etc.) and floating particles were fed every day, and water was added from the water injection pipe to brake the floating particles during feeding. Toad feeding and domestication. At the beginning, the proportion of live bait was large, and then decreased gradually. after the toad had a fixed feeding habit, the net of the small pond could be opened and the toad could be put into the paddy field to find food freely.

After the field management toad entered the rice field, the field water quality was kept relatively fresh in advance. In the hot summer, the field should often irrigate "horse race water" to adjust the water temperature and water quality. In addition, if a disease occurs in rice, spraying pesticides should choose sunny days, the nozzle is facing up, and the fog flowers should be fine, so as not to sink the medicine as far as possible. Once the drug deposition in the field is too thick, water injection is immediately adjusted. In general, there is no need to apply pesticides because toads have the ability to catch pests. Young toads should prevent their natural enemies such as snakes and eagles in the field. Toads will not get sick under general natural conditions, but we should pay attention to mechanical bruises, resulting in traumatic infection. Therefore, special attention should be paid to the arrest, which can only be caught with a cloth pocket. Two months after the toad was put into the rice field, it was screened once a month to catch the big and stay small, and then placed in a special culture pond for collecting toad clothes, toad venom, or for sale.
