High-yield breeding method of freshwater fishes

Abstract

The invention discloses a high-yield breeding method of freshwater fishes. The high-yield breeding method comprises the following steps of S1, selecting fingerlings; S2, sterilizing and disinfecting a fishpond, installing a water pump and a heater, preparing improved silt soil, laying the improved silt soil onto the bottom of the sterilized and disinfected fishpond, applying a compound fertilizer to the surface of the improved silt soil, covering the soil with film, adding aquatic plants into the fishpond, then adding water, controlling the water temperature in the fishpond, and completing improvement of the fishpond; S3, putting the fingerlings into the fishpond, putting fish feed, reducing the putting frequency of the fish feed to 4 times every day when the weight of the fingerings is increased to double the weight of the fingerlings at the moment of putting, and maintaining the frequency until the freshwater fishes are harvested; S4, periodically starting up the water pump, conducting inspection, throwing a water flea killing agent, fishing excessive aquatic plants and sick fishes, injecting water, harvesting the fishes when the fingerlings in the fishpond are mature, and then completing high-yield breeding of the freshwater fishes. According to the breeding method, the yield of the bred freshwater fishes is high, the quality is high, the meat is smooth and tender, and the number of the sick fishes is small.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to a high-yield farming method for freshwater fish. Background technique [0002] Fish is one of the common animals in people's daily life. Some breeds have ornamental functions, while some fish species are often used as good products for people to make dishes, such as crucian carp, grass carp, silver carp, perch, catfish, etc. among freshwater fish. regular product. But when we buy freshwater fish, we will find that the price of the same species of freshwater fish also has certain differences, and the difference in size and meat quality will affect the price of freshwater fish. The most important factors affecting the differences in fish size and meat quality are the breeding environment and breeding methods of freshwater fish. Reasonable breeding environment and breeding methods can accelerate the growth of fish, improve the quality of fish meat, and increase the output of ...
