Ecological environment-friendly breeding method for increasing black carp yield through viviparous and black carp matched breeding

Abstract

The invention relates to the field of aquaculture, and discloses an ecological environment-friendly breeding method for increasing the black carp yield through viviparous and black carp matched breeding. By scientifically and reasonably establishing a viviparous pond, a black carp pond and other related facilities in a matched mode, the traditional pond breeding mode with silver carp and bighead carp as the main is changed into the breeding mode with black carp as the main, the breeding ratio of black carp is increased to be 60% or above, the mode of directly putting artificial matched feed in the black carp pond is changed into the mode of putting in viviparous, the pollution to water quality of the fish ponds is avoided, and the problem that public hazards are caused to aquaculture by water quality pollution is solved; by means of the method, the black carp yield is increased, the economic income of farmers is improved, breeding cost is reduced, the black carp quality is improved, the ecological environment-friendly healthy breeding mode is achieved, and the method has great popularization value.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an eco-environmental and environment-friendly breeding method for raising the yield of herring by supporting the cultivation of snails and herrings. The method of the invention can increase the feeding ratio of herrings in pond breeding to more than 60%, and the feeding of mixed fish with it The ratio drops to below 40%, greatly improving the economic benefits of breeding enterprises. Background technique [0002] At present, herring is raised in traditional ponds in my country, and the mixed culture of herring, silver carp, bighead carp, grass carp, etc. is generally adopted. The breeding ratio of herring is less than 20%, generally not more than 10%, and the breeding ratio of silver carp, bighead carp, and grass carp is as high as 80%. %above. Due to the high price of herring, it can reach 10-12 yuan per catty, while the price of silver carp, bighead carp, and grass carp is only 4.5-...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of snail and herring supporting breeding to improve the economic benefits of breeding for the current immature snail and herring breeding technology, resulting in the large-scale herring breeding can only rely on artificial compound feed feeding, herring meat quality is poor, and the economic benefits of breeding are not high.
