Problems solved by technology

[0004] With the development of aquaculture, a large amount of feed is required for high-density farming. Feed residues and aquatic animal excrement will pollute the aquaculture water body, resulting in the increase of harmful substances such as ammonia, hydrogen sulfide, and organic matter, and the increase of COD and BOD. Therefore, , in order to solve the above problems, it is urgent to provide a new technical solution

Abstract

The invention relates to the technical field of ecological purification of aquaculture water, and particularly discloses a plant fermentation extract for freshwater aquaculture and a preparation method thereof. The plant fermentation extract for freshwater aquaculture is prepared by mixing equisetum hiemale, gordon euryale seed, cuttlebone, cordyceps sinensis, cyrtomium rhizome, hirudin, dried earthworm, rhizoma phragmitis, chitosan oligosaccharide, isomaltooligosacharide, liquorice, typha angustifolia root, selenium yeast and iron-enriched yeast as raw materials according to a certain weight ratio, fermenting, extracting and pulverizing. The raw materials are easy to obtain, the preparation process is simple, pathogenic microorganisms and bad algae in aquaculture fresh water are effectively reduced, the immunity and disease resistance of aquaculture objects are obviously enhanced, the morbidity is reduced, the survival rate is increased, the water quality is improved, and the service cycle of the aquaculture fresh water is prolonged.

Description

technical field [0001] The invention relates to the technical field of ecological purification of aquaculture water, in particular to a plant fermentation extract used for freshwater aquaculture and a preparation method thereof. Background technique [0002] Freshwater aquaculture refers to the use of ponds, reservoirs, lakes, rivers and other inland waters to raise and breed aquatic economic animals and aquatic economic plants. It is an important part of inland aquaculture. The fishes are mainly cultured, the shrimps cultured include Macrobrachium rosenbergii and Hainan prawns, and the crabs cultured are mainly river crabs. At present, China's freshwater farmed fish mainly include: herring, grass carp, silver carp, bighead carp, crucian carp, bream, bream, dace and other economic fish. The area and output of freshwater aquaculture in China rank first in the world. [0003] Ponds are generally small in size and widely distributed. The water quality is easy to control, and ...
