Problems solved by technology

[0002] The muscle of the grass carp is rich in protein, vitamins, minerals and amino acids, which is easy to digest and absorb. Stocking, lack of scientific management, this method of breeding, the survival rate of the grass carp is low, the growth rate is slow, and the output is not high; with the acceleration of the urbanization process, the area of ​​agricultural land is decreasing year by year, and land resources are increasingly scarce. How to improve The utilization rate of the land, scientifically and rationally raising the grass carp with high survival rate, fast growth speed and tender meat in the rice field is an important issue that people urgently need to solve

Abstract

The invention discloses a method for breeding procypris merus in a rice field and belongs to the technical field of aquatic product breeding. The method for breeding procypris merus in the rice field includes the steps of rice field selection, fish ditch excavation, ridge heightening and strengthening, fry release, bait feeding, rice field fertilization and rice field management. The method has the advantages that land resources are reasonably used, breeding management is scientific, the survival rate of procypris merus and the yield are high, tender grass, duckweed, insects and rice seedling pollen in the rice field serve as main feed, economic cost is reduced, fish are ecologically bred, and meat of the acquired procypris merus is tender, fishbones are thin and soft, and the procypris merus is free of the fishy smell.

Description
