Embodiment Construction

[0036] One, the grass carp culture method in stages, including the first stage and the second stage; the first stage is to raise grass carp in the mode of throwing and feeding compound feed in the plain intensive culture pond; the second stage transfers the grass carp in the plain intensive culture pond to In the breeding device, the method of introducing part of the flowing stream water or mountain spring water and feeding grass is carried out.

[0037] Among them, the time for grass carp to enter the pond in the first stage is from January to March every year, the size of the pond is 20-50g / carp, and the stocking density is 1000-1500 / mu; the grass carp in the first stage is fed with compound feed. The range of protein content is 28% ≤ protein content ≤ 30%. Grass carp in the first stage need to be sterilized and insecticided to ensure their health one week before they are transferred to the breeding facility for the second stage of cultivation. The second stage includes the ...

Abstract

The invention discloses a segmented culture method for grass carps. The method comprises a first stage and a second stage, wherein in the first stage, the grass carps are bred in a plain intensive culture pond in a mode of feeding compound feed; in the second stage, the grass carps in the plain intensive culture pond are transferred into the culture device, and culture is performed in a mode of introducing part of flowing stream water or mountain spring water and feeding forage. According to the method, the high-quality water quality condition of stream water or mountain spring water is utilized, special forage is supplemented, and various technical measures such as ecological water transfer are combined, so that the grass carps are bred in sections, the quality and economic benefits of the grass carps are improved, and the healthy sustainable development of the grass carp breeding industry is effectively promoted.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a segmented cultivation method for grass carp. Background technique [0002] Grass carp, green carp, silver carp and bighead carp are the four traditional Chinese carp with a wide audience. Among them, grass carp has the largest breeding volume and the widest breeding coverage. Its meat is delicious and the price is affordable, and it is deeply loved by consumers. Data from the China Fishery Statistical Yearbook show that in recent years, the national grass carp aquaculture output has been around 5.5 million tons, ranking first among all farmed fish, and has played a significant role in ensuring that the whole people can obtain high-quality animal protein sources. At present, grass carp farming mainly adopts the method of pond culture, which is a high-density, high-input, and high-output model. The per unit yield of grass carp is getting higher and higher, but the quality of ...
