Springtime high-yield freshwater shrimp breeding method

Abstract

The invention discloses a springtime high-yield freshwater shrimp breeding method. The springtime high-yield freshwater shrimp breeding method comprises the steps that a pond free of silt at the bottom is selected, pond water is complete pumped out in the first ten-day period of January, then the pond is exposed to the sun, and quick lime is evenly scattered at the bottom of the pond; after water injection is performed in first ten-day period of February, hydrilla verticillata is sowed and planted at the bottom of the pond, water injection is performed, then alternanthera philoxeroides are planted in a shallow water zone of the pond, and water injection is performed; a summer flower net is arranged in the middle of the pond; shrimp larvae are put in the pond in the early morning of fine days in the first ten-day period of March for a period of time, and then silver carps are put in the pond; after putting, a fine-grain feed is put for one time in the morning and afternoon every day; fishing is performed the last ten-day period of May, water at the bottom of the pond is pumped for one every week to make the water level in the pond lowered, then fresh water is supplemented to reach the previous water level before water pumping, and meanwhile air is pumped into the pond; fishing is performed in the afternoons of cloudy days after a period of time after putting.

Description

technical field

[0001] The invention relates to the technical field of spring freshwater shrimp cultivation methods, in particular to a high-yield spring freshwater shrimp cultivation method. 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. Contents of the invention
