Freshwater fish pollution-free green cultivation method

Abstract

The invention relates to a freshwater fish pollution-free green cultivation method which includes the following steps: step 1 is that a pond is cleaned in early days of April, and bleaching powder is used to disinfect the pond bottom of the fishpond; step 2 is that fish fries are placed into the fishpond when water temperature reaches 10 DEG C -12 DEG C, a mixed breeding method is adopted in the fish fries, and various fish fries are disinfected by disinfectant before release; step 3 is feeding fish feed, and the amount of fish feed is 2% of the amount of the fish fries; step 4 is that water in the fishpond is disinfected and insects in the water are killed; and step 5 is that disinfecting and insect killing are carried out once each month and new water is injected once each month since May, one third of water in the fishpond is replaced each time until October, and then adult fish can be caught. By means of the mixing breeding method, the freshwater fish pollution-free green cultivation method improves breeding efficiency and disease prevention and disease resistance abilities between various fishes at the same time, and promotes health of the fish.

Description

technical field [0001] The invention belongs to the field of aquaculture, and relates to the aquaculture of freshwater fish, in particular to a pollution-free green aquaculture method for freshwater fish. Background technique [0002] With the development of the market economy and the increase of people's material needs, the breeding industry has become more and more developed, and natural breeding has been replaced by more and more artificial breeding. Although artificial breeding has solved people's material needs, some farmers have used drugs prohibited by the state to promote growth and fattening. Although the output has increased, the taste and nutrition of the meat have been greatly affected, resulting in abnormal development of the breeding industry. [0003] Therefore, the current aquaculture industry, especially freshwater fish aquaculture, requires scientific feeding to achieve the succulent nutrition of natural freshwater fish, and to make freshwater fish as healt...
