The grasshopper is also called a otter. China's traditional Chinese medicine for treatment of stroke, rheumatism, pain, drooling, hepatosplenomegaly, amenorrhea, paraplegia and angina pectoris.
Aquaculture ponds should be sheltered from the sun and drained to facilitate the construction of pools. The area should be small and not large. There are water inlets and outlets at the opposite corners of the pool. Put some stones and branches at the bottom of the pool for grasshoppers to inhabit. Grasshopper seedlings can be grown or purchased, and it is better to use a wide range of money. The grasshopper is hermaphrodite and each breeds eggs. Summer and autumn are the breeding season and the best season for catching. The standard for seeding is robust and non-injury, with a specification of 20-40 grams per treaty. Such leeches spawn more and have higher hatching rates. They can be grown and processed for sale in early spring in June. 10-15 kilograms of leech seedlings are stocked on the water surface per acre.
The vitality of the grasshopper is particularly strong, and feeding and management need to grasp feeding and water quality regulation. Grasshoppers mainly feed on snails, sucking blood, sucking fish, frogs, livestock, and other animals. The artificially fed bait is mainly blood, rice bran, etc. of various animals. Each mu of water puts about 25 kilograms of snails at one time, allowing them to breed naturally, feeding grasshoppers and feeding animal blood once a week. The leech has strict requirements on the environment and water quality. It can also grow in the sewage. However, with high-density farming, the water quality should be kept clean, and there must be a certain amount of dissolved oxygen. In the hot season from July to August, it is necessary to change the water regularly.
After winter, the grasshopper stopped feeding and hibernated into the soil to hibernate. Grasshoppers that have been stocked in the early spring have generally grown into winter, drained the water, fished out with a net, and selected individuals with large, well-growth seeds (15 kg per acre) and concentrated their inputs into the breeding pool for wintering. Other harvesting processing.
From April to October, the outer layer of the grasshopper's ovary is spongy, prolific in the semi-humid sloppy soil in the field hoe, so the paddy field should not be too deep when it is used to keep leeches. Pay attention to the drainage in the rainy days and the water level should not be soaked. The turf inside, otherwise the egg is easy to die. One pod can hatch 10-20 grasshoppers.
