A kind of culture method of preventing disease and increasing production of freshwater shrimp in summer

Abstract

The invention discloses a disease resisting and yield increasing culture method for freshwater shrimps in summer. The method comprises: selecting a pond whose bottom does not have sludge, in later June and after pond water is pump out completely, exposing the pond to the sun, then uniformly scattering quick lime on the bottom of the pond; in early July after water injection, uniformly scattering and sowing to plant hydrilla varticillata on the bottom of the pond, then planting alternanthera philoxeroides in a shallow water zone of the pond, injecting water; then arranging a summer flower net on the middle part of the pond; selecting a sunny early morning in late July, putting shrimp seeds into the pond, then putting silver carps into the pond; after putting the shrimp seeds and the silver carps, respectively feeding fine pellet feed for one time every morning and every afternoon; after a time, respectively feeding coarse pellet feed for one time every morning and every afternoon; putting quick lime and copper sulfate aqueous solution into the pond at set intervals; from late August to fishing, pumping water out from the bottom of the pond once a week, then supplementing fresh water to the water level before the water level is lowered, pumping air into the pond at fixed time every day; after putting the shrimp seeds in for a period of time, selecting a cloudy afternoon to catch the shrimps.

Description

technical field [0001] The invention relates to the technical field of summer freshwater shrimp cultivation methods, in particular to a summer freshwater shrimp cultivation method for disease prevention and production increase. Background technique [0002] Freshwater shrimp is one of the freshwater shrimps with high economic value and nutritional value. It has the characteristics of fast growth, large individual, fast reproduction and strong vitality. Freshwater shrimp is tender and delicious, and rich in nutrition. grams or more. Freshwater shrimp generally inhabit rivers, lakes, ponds, shallow waters along the banks of ditches or in slow streams overgrown with aquatic plants. They hibernate in shaded places during the day and are active at night. They often climb and crawl on the bottom of the water, aquatic plants and other objects. During the artificial breeding process, shrimps are extremely vulnerable to pests and diseases, which increases the risk of dead shrimps. ...
