Culture method for grass carp

Abstract

The invention provides a culture method for grass carp. The culture method comprises the following steps: firstly, establishing an ecological culture pond: selecting a place which orients from south to north, and has the advantages of sun trap, convenience in irrigation and drainage and sufficient sunlight for building the culture pond, sterilizing with quick lime, cleaning the pond with clear water, adopting loose sandy soil rich in humus at the periphery, which is close to a water source, of the culture pond, building a platform with the width of 70 to 80cm, paving a layer of pond silt withthe thickness of 30 to 40cm at the bottom of the pond, planting aquatic plants on the silt and then injecting clean pollution-free water; secondly, stocking the grass carp: mixing adult grass carp with a small amount of bighead carp, carp and golden carp for stocking, and adopting a high-density stocking mode; thirdly, feeding feed: feeding artificial feed, wherein the daily feeding amount of theartificial feed is 0.4 to 0.8 percent of the total weight of the carp. The grass carp cultured with the method has the advantages of slime shape, reduced fat, tough and elastic meat quality, increaseddelicious, smooth and tender mouth feel as well as delicious taste and mouth feel of naturally-growing grass carp.

Description

technical field [0001] The invention belongs to the technical field of freshwater fish culture, and in particular relates to a grass carp culture method. Background technique [0002] Grass carp, also known as grass carp, is one of the unique "four major fishes" in my country. It is a typical herbivorous fish. It is rich in nutrients, high in protein, and has the characteristics of fast growth, strong adaptability and high yield. People's main dietary protein. In 2009, the national grass carp aquaculture output was 4.08 million tons, accounting for more than 40% of the total output of the "four major fishes", and its industrial status is very important. [0003] Common grass carp breeding methods are basically mature and perfect. There are intensive farming techniques such as cages, ponds, and reservoirs. The stocking models, feeding techniques, and feed formulas are also varied. for purpose. Compared with naturally grown products, artificially cultured products have the d...

Problems solved by technology

This method is simple and can achieve the desired effect, but its negative effects are: ① The antibiotics that have not been metabolized are accumulated in the fish, causing the antibiotics in the fish to exceed the standard, or even seriously exceeding the standard, endangering the health of consumers; ② Long-term use of antibiotic feed Additives, the immune function of freshwater fish is reduced, leading to drug resistance of bacteria, increasing the risk of disease outbreaks and the difficulty of disease control
