A kind of cultivation method of high-quality grass carp

Abstract

The invention discloses a high quality grass carp culture method, and mantis shrimps and grass carps are in mixed breeding; the method comprises the following steps: culture pond preparation, fish body selection and inputting, bait feeding, salinity management and finished product catching. Compared with the prior art, the advantages are that the mantis shrimps and grass carps are cultured in the pond, sinking fodders are added so as to provide mantis shrimps needed salinity, and the mantis shrimps can also ingest grass carp remaining baits, thus reducing pond pollution and bait waste; bait ingredients and pond water components are adjusted in different stages, so the mantis shrimps and grass carps can both absorb nutrition in different stages, thus improving anti-disease ability, and realizing fast growing; the grass carp bait comprises fresh grass forage, partial meat forage and mixed feed; the mantis shrimps can promote grass carps to frequently swim, thus increasing nitrogen accumulation in the fish body, enhancing liver pancreas and muscle activity, so the grass carps can be more delicious in taste; adult fish internal crude protein and crude fat content can be increased, thus greatly improving grass carp quality.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for cultivating high-quality grass carp. Background technique [0002] Grass carp is favored by consumers for its tender meat, large body, and few intermuscular spines. However, during the breeding process of grass carp, the development of grass carp farming is restricted due to its susceptibility to disease. Through production practice, immune injection technology is usually used to solve the problem. This problem, but with the expansion of breeding, there will be new diseases. At present, in order to expand the cultivation, the breeding quantity of grass carp is blindly increased. The meat quality and nutrition of grass carp are seriously affected, and the decrease in taste will also affect its sales. Therefore, it is necessary to improve the disease resistance of grass carp by improving the breeding method, and at the same time cultivate high-quality g...
