Abstract

The invention discloses a breeding method for ctenopharyngodon idellus. The breeding method comprises the following steps: site selection and construction of a fish pond; fingerling stocking; breedingmanagement; water quality management and disease prevention and control. Beer sludge is paved at the bottom of the breeding pond to culture microorganisms in water to grow, so that the dosage of a feed is reduced. 350-500 g / grass carp is selected as a fingerling, the grass carps which are less than 2kg are fed as common ctenopharyngodon idellus, so that the culture period of crisped grass carps can be shortened. In a crisping middle period, the feed amount is adjusted according to water temperature. Fermented broad beans are adopted. Most anti-nutrient factors can be removed after the broad beans are fermented, so that the absorptivity of the grass carps to the broad beans can be improved and the crisping process is accelerated. In the feeding process, special feeds are used to provide abundant nutrients to growth of the grass carps, so that the fish meat quality is ensured.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for raising grass carp. Background technique [0002] Grass carp, also known as grass carp, is one of the four major family carps and is the main farmed fish in my country. It grows fast and has a high yield, but its muscles are relatively loose, and it needs to be marinated to keep it from dispersing, which affects the taste and price. By feeding broad beans, that is, embrittlement culture can make the grass carp meat crisper, and the grass carp that has been successfully embrittled is called crispy carp or embrittled carp. [0003] Crispy meat carp is firm, soft, refreshing, crispy and delicious. Studies have shown that the content of fat and umami amino acids in crispy carp is significantly higher than that of grass carp, and also higher than that of some other fish. Therefore, crispy carp has better taste and unique taste, so it is very popular among consumers. Crispy ca...
