Water fertilization method for using fermented pigeon dung to cultivate food organisms for ornamental shrimps

Abstract

The invention relates to a quick water fertilization method for adding fermented pigeon dung to cultivate food organisms for ornamental shrimps, which includes the steps: well mixing dry pigeon dung, auxiliary material and BGB (brilliant green bile broth) microbial inoculants with added water to obtain mixed fermented stock, wherein the auxiliary material is one or mixed two of wheat bran, corn starch and rice husk; hermetically placing the mixed fermented stock in the shade at the ambient temperature of 15-28 DEG C for viable microbial fermentation, and obtaining fermented pigeon manure when the surface of the mixed fermented stock is covered with white filiform mycelia; cleaning and disinfecting a breeding pond for ornamental shrimps, applying 75-150g of the fermented pigeon manure into the pond per square meter of water in the breeding pond for ornamental shrimps, and placing young ornamental shrimps into the pond for cultivation 3-5 days after application of the fermented pigeon manure. The water fertilization method has the advantages of short fermentation time, fast water fertilization speed, low fertilizer consumption, high food organism cultivating efficiency and the like.

Description

technical field [0001] The invention relates to a fertilizer and water method for ornamental shrimp bait organisms, in particular to a rapid fertilizer and water method for cultivating ornamental shrimp bait organisms by adding fermented pigeon manure, which belongs to the technical field of aquaculture. Background technique [0002] The biological cultivation of bait is the key to improving the survival rate of shrimp seedlings in the breeding process of ornamental shrimp. To realize the large-scale artificial propagation of ornamental shrimp, it is necessary to provide a large amount of palatable opening bait for the shrimp seedlings that have just emerged from the film, and suitable biological live bait can undoubtedly be used. Greatly improve the survival rate of seedlings.

Problems solved by technology

[0003] At present, the ornamental aquaculture industry usually chooses pig manure, chicken manure, cow manure and other farmyard manure to make organic fertilizer by composting and decomposing method, which is used to cultivate biological live bait for ornamental shrimp seedlings. This kind of conventional poultry and livestock manure has low fertilizer efficiency. The amount of fertilizer used is large, the fertilizer effect when applied to the water body is slow, and the efficiency of fertilizer and water is low, resulting in insufficient supply of bait organisms, resulting in low survival rate of ornamental shrimp seedlings, which is not conducive to large-scale reproduction and production of ornamental shrimp seedlings; in addition, this direct composting and decomposing method, The fermentation quality of its organic fertilizer is low and the fermentation cycle is long; moreover, the bait organisms cultivated in the later stage of pig manure and chicken manure are mostly large plankton such as cladocera and copepods, which are not good for the digestion of ornamental shrimp and shrimp seedlings.
