Method for breeding high-yield silver carps

Abstract

The invention relates to a method for breeding high-yield silver carps. The method includes the following steps: before fries are put into a pond, water plants are planted in the pond, and fine sand with the thickness ranging from 1 cm to 2 cm is laid at the bottom of the pond; the silver-carp fries are put into the pond when the silver-carp fries grow to range from 3 cm to 4 cm, and before being put into the pond, the fries are processed through 1% of baking soda solutions for two minutes; from one month to five months after the fries are put into the pond, the fries are fed through feed A; in the time after five months after the fries are put into the pond, the fries are fed through feed B; in one month before the silver carps are taken out of the pond, the silver carps are fed through feed C. According to the method for breeding the silver carps, as the silver-carp fries are processed before being put into the pond, the adaptive capacity of the silver carps to the environment is improved, and death of the fries after the fries are put into the pond is prevented; as the different feeds are used in different growth periods, more pertinence can be achieved, the content of calcium and the content of protein are increased in the earlier growth stage, and the growing speed of the silver carps is increased.

Description

technical field [0001] The invention belongs to the field of breeding, and in particular relates to a breeding method for high-yield silver carp. Background technique [0002] The body is flat on the sides, slightly taller, fusiform, blue-gray on the back, white on both sides and abdomen. Pectoral fins do not extend beyond base of pelvic fins. The fins are grayish white. The head is large. The eyes are set low. The scales are tiny. The horny ridge in the middle of the abdomen extends from the bottom of the pectoral fins to the anus. Similar in shape to bighead carp, silver carp is impatient and good at jumping. [0003] Silver carp is sweet in taste, flat in nature, non-toxic, and its meat is fresh and tender, rich in nutrition. It is one of the excellent fish species that are more suitable for breeding. It is one of the main freshwater aquaculture fishes in my country. Distributed in major water systems across the country. Silver carp is a large-scale freshwater fi...
