Freshwater fish pollution-free culture method

Abstract

The invention relates to a freshwater fish pollution-free culture method comprising the following steps: 1, culture pond requirements; 2, irrigation and water quality regulation; 3, fish fingerling selection; 4, fish body disinfection; 5, reasonable stocking; 6, breeding; 7, water quality control; 8, adding certain amount of aquatic product culture special-purpose fertilizer and microzyme into the culture pond after each time water adding; 9, properly catching. The beneficial effects are that the fish pond and fish body are disinfected and scientifically fed, thus effectively reducing drugs and artificial feed amount, and the cultured freshwater fish is high in quality and safety, and pollution free; fish fingerlings living in different water area depths can be mixed in the culture pond, and the various species can effectively utilize fish pond different water area depth spaces; ordered catching in batches can improve culture quantity and can increase fisherman incomes.

Description

technical field [0001] The invention relates to a pollution-free breeding method for freshwater fish. Background technique [0002] Freshwater fish refers to fish that live in fresh water, and there are many kinds, accounting for about 40% of the total fish.
