High-yield culture method for intercropping spotted silver carp, crucian carp, dace and black carp

Abstract

The invention belongs to the technical field of ecological breeding, and discloses a high-yield breeding method for intercropping spotted silver carps, crucian carps, dace and black carps. The culture method comprises the following steps: (1) dredging and drying a culture pond in the sun, then splashing a traditional Chinese medicine component disinfectant for disinfection, and then splashing an EM (Effective Microorganisms) diluent for bottom mud maintenance after superficial layer clear water is stored; (2) the pond after bottom mud maintenance in the step (1) is filled with water, and then fries of spotted silver carps, crucian carps, dace and black carps are put into the pond; (3) the mixed fish feed fermented by traditional Chinese medicine probiotics is used for feeding once in the morning and once in the evening every day, the feeding rate is 1.5%-3.5%, and the fishes are bred until adult fishes are harvested. According to the breeding method, traditional Chinese medicine component disinfectant is adopted for disinfection treatment, EM bacterial liquid is adopted for enhancing and improving treatment, the breeding yield can be increased, and the delicious taste of fish can be improved. The culture benefit is obviously increased.

Description

technical field [0001] The invention belongs to the technical field of ecological breeding, in particular to a high-yield breeding method for silver carp, crucian carp, dace and herring in sets. Background technique [0002] Silver carp is also called fat head fish, silver carp and black carp. It is a kind of important freshwater fish carp family in our country, and it is born in various water systems and lakes. Silver carp mainly eats zooplankton and protozoa such as rotifers, cladocerans, copepods (such as Cyclops), and also eats some phytoplankton (such as diatoms and cyanobacteria) and artificial feed phytoplankton, and also eats soybean milk, Bean dregs powder and rice bran, etc., prefer to eat artificial microparticle compound feed. Suitable for breeding in fertile water. It is a large fish that can weigh 30-40 kg in natural rivers. Silver carp generally live in the middle and upper layers of the water. In spring, summer and autumn, silver carp spend most of their...

Patent CN 107466914 A also does not adjust the corresponding feed for the living habits or eating habits of different fish

[0010] In addition, quicklime is often used in the disinfection treatment of aquaculture ponds in the existing aquaculture technology. However, quicklime disinfection will lead to the disappearance of beneficial bacteria in the pond soil, and will cause the soil to be too alkaline, which is not conducive to the subsequent growth of beneficial microorganisms, animals and plants, and destroys The micro-ecological environment of the aquaculture pond is impaired, and the fertility in the aquaculture pond is weakened

The source of nutrition for fish growth is completely dependent on artificial feed, resulting in the lack of delicious taste of wild fish and low quality.
