A kind of high-yield culture method of improving immunity of summer freshwater shrimp

Abstract

The invention discloses a high-yield culture method for improving immunity of freshwater shrimps in summer. The method comprises the steps that a pond free of sludge at the bottom is selected, after pond water is pumped out in late June, the pond is insolated, and then quick lime is evenly scattered to the bottom of the pond; after water is injected in the first ten days of July, hydrilla varticillata is evenly scattered and planted in the bottom of the pond, then alternanthera philoxeroides is planted in the shallow water zone of the pond, and water is injected; then a summer flower net is arranged in the middle of the pond; young shrimps are put in the pond on a sunny morning in the last ten days of July, and then chubs are put in the pond; after the freshwater shrimps are put in the pond, the freshwater shrimps are fed with fine pellet feed once in the morning and afternoon every day; after a period of time, the freshwater shrimps are fed with rough pellet feed once in the morning and afternoon every day; quick lime and a copper sulfate water solution is put in the pond every other a period of time; from late August to fishing, the pond bottom water is pumped once every day, then a fresh water source is supplemented to the water level which is not lowered, and meanwhile air is pumped into the pond regularly every day; after the freshwater shrimps are put in the pond for a period of time, the freshwater shrimps are fished on a cloudy afternoon.

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 summer freshwater shrimp with improved immunity. Background technique [0002] Freshwater shrimp is a kind of aquatic product with high economic value. It is a good means to get rid of poverty and become rich in southern regions with many water systems, especially in marginal poverty-stricken areas such as mountainous areas and forest areas. However, during the culture process of freshwater shrimp, it is very easy to produce parasitic pests such as clumpworm and polyshrinker, and the infestation of diseases such as black gill disease and red body disease, which seriously affect the yield and quality of freshwater shrimp. The traditional prevention and control of diseases and insect pests starts from the perspectives of disinfection and sterilization. While it is effective, it also brings hidden dangers to th...

Problems solved by technology

However, in the process of culturing freshwater shrimp, it is very easy to produce parasitic pests such as clump worms and shrinkage worms, and infestation of diseases such as black gill disease and red body disease, which seriously affect the yield and quality of freshwater shrimp.

The traditional prevention and control of diseases and insect pests starts from the perspectives of disinfection and sterilization. While it is effective, it also brings hidden dangers to the food safety of freshwater shrimp. For this reason, can the disinfection be carried out by improving the immunity of freshwater shrimp and assisting the use of quicklime at the same time? Become the focus of industry research
