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

Embodiment

[0036] The fish pond is located by the Luan River in Fengning County, Hebei Province. It is connected to the Luan River through the upper gate, and the lower gate is a discharge gate. The area of ​​a single fish pond is 5 mu. The water level of the fish pond is controlled at 2-2.2 meters in winter and 1-1.3 meters in summer. At the beginning of May, common carp fry are stocked in fish ponds per acre.

[0037] About 6.5 kg of Chinese herbal medicine is used per mu of fish pond. Among them, Zanthoxylum bungeanum is mainly 2.0 kg, 1 kg each of licorice, Bupleurum, and skullcap, and 0.5 kg each of Cimicifuga, Pulsatilla, and garlic. The method of use is to pack them into small bags with plastic mesh cloth with a mesh size of 0.25 square centimeters, put them into the water inlet of the fish pond, soak them for 10 days, take them out, use them every 10 days, and replace each time with a new Chinese herbal medicine bag. The medication period is from early May to mid-September.

Abstract

The invention provides an ecological fish-farming method. The ecological fish-farming method is characterized in that water treatment is carried out by using Chinese herbal medicines so as to prevent fish diseases. In a typical embodiment of the invention, a Chinese herbal medicine composition comprising thymus quinquecostatus, radix glycyrrhizae, radix bupleuri, radix scutellariae, roots of Chinese pulsatilla, rhizoma cimicifugae and garlic is added into a fishpond for farming gold-wing carps with good effect. In a preferable implementation way, the fishpond is kept to be communicated with an external outer source, so that water is changed with small flow per day; water diversion quantity is 1/32 to 1/4 the volume of fishpond water; and flow regulation is carried out according to different seasons. The fish-farming method disclosed by the invention can keep good water quality, and is beneficial for healthy growth of freshwater fish; chemicals are not required, so that green ecological farming is realized, and therefore, common carp fry can be farmed into gold-wing carps.

Description

technical field [0001] The invention relates to aquatic product cultivation, in particular to a method for cultivating freshwater fish, more specifically to an ecological method for cultivating 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 days...
