A kind of high-yield cultivation method of freshwater shrimp in summer pond

Abstract

The invention discloses a high-yield breeding method of freshwater shrimps in a pond in summer. The high-yield breeding method includes: selecting a pond without sludge at the bottom, draining water in the pond in late June, exposing the pond under blazing sun, and uniformly scattering quicklime at the bottom of the pond; injecting water into the pond at early July, uniformly sowing and planting Hydrilla varticillata, planting Alternanthera philoxeroides in a shallow region of the pond, and injecting water; arranging summer flower net in the middle of the pond; in an early morning of a sunny day in late July, placing young shrimps into the pond, and then placing silver carps into the pond; after the young shrimps and the silver carps are placed into the pond, feeding fine granulated feed a time every morning and every afternoon; after a period of time, feeding rough granulated feed a time every morning and every afternoon; putting quicklime and a copper sulfate water solution into the pond every other period of time; from later August to time of fishing, extracting water at the bottom of the pond a time every week, supplementing fresh water to reach a water level before extraction, and regularly pumping air into the pond every day; after a period of time, selecting the afternoon of a cloudy day for fishing.

Description

technical field [0001] The invention relates to the technical field of summer freshwater shrimp cultivation methods, in particular to a high-yield cultivation method for freshwater shrimp in summer ponds. Background technique [0002] With the rapid development of social economy, people's protein sources are not limited to meat, eggs and poultry. Aquatic products are also an excellent source. Green shrimp is a high-quality, easy-to-raise protein source. Artificial culture of freshwater shrimp has gradually become an important means for some enterprises and farmers to survive. Especially in some economically backward areas, pond culture of freshwater shrimp has become an important part of agricultural income increase. However, freshwater prawns in ponds—especially in summer—are likely to be infected with diseases and insect pests, resulting in reduced production. Therefore, focusing on enhancing the resistance of freshwater prawns and assisting in pond sterilization are effec...

However, freshwater prawns in ponds—especially in summer—are likely to be infected with diseases and insect pests, resulting in reduced production. Therefore, focusing on enhancing the resistance of freshwater prawns and assisting in pond sterilization are effective methods to prevent freshwater prawns from being infected with dead shrimp
