Problems solved by technology

Once a fish disease occurs, it can only be treated with chemical drugs, which will damage the taste of the fish and human health.
[0003] In short, the fish farming methods in the prior art rely on chemical drugs or chemical disinfectants for disease prevention and control, and the market lacks greener, more environmentally friendly freshwater fish farming methods that meet ecological requirements

Abstract

The invention provides an ecological fish farming method, which is characterized in that Chinese herbal medicine is used to treat water bodies and prevent fish diseases. In a typical embodiment of the present invention, the Chinese herbal medicine composition comprising Zanthoxylum bungeanum, Radix Glycyrrhizae, Radix Bupleurum, Scutellaria baicalensis, Pulsatilla, Cimicifuga and garlic are put into fish ponds, and golden-finned carp are cultured, and good results have been obtained. Effect. In a more preferred embodiment, the fish pond is kept in communication with the external water source, and the water is exchanged with a small flow every day, and the water diversion is 1 / 32 to 1 / 4 of the water volume of the fish pond, and the flow is adjusted according to different seasons. The fish farming method of the invention can maintain good water quality, is beneficial to the healthy growth of freshwater fish, realizes green ecological farming without using chemicals, and can grow common carp fry into golden-finned carp.

Description

technical field [0001] The invention relates to aquatic product cultivation, in particular to a method for cultivating freshwater fish, and more particularly to an ecological cultivation method for freshwater fish. Background technique [0002] In freshwater fish farming, the prevention of fish diseases is an important aspect of farming. In addition to strictly disinfecting fish ponds, it is also necessary to do a good job of "four eliminations", namely: fish body disinfection, bait fertilizer disinfection, net gear disinfection, and food court disinfection. Sometimes chemicals are also used to eliminate various pathogens in the water. This disinfection work is time-consuming and laborious, and the use of chemical drugs is not conducive to human health. Because current fish culture adopts the method of static water culture and regular water change more, the water in the fish pond is kept for several days, and the water is completely changed every other stage, such as 6-15 ...
