Ecological breeding method of grass carp

Abstract

The invention discloses an ecological breeding method of grass carp. The ecological breeding method includes following steps: (1), selecting a site, and building a fish pond; (2), preparing before stocking; (3), treating fries before releasing; (4), managing feeding; (5), managing water quality; (6), preventing and treating disease; (7), regularly fishing. The fries bred by the ecological breeding method is high in survival rate and disease resistance; the grass carp is high in growing speed, delicious in meat quality and high in yield; drug release is reduced, so that drug residue in bodies of the grass carp is avoided well.

Description

technical field [0001] The invention relates to the technical field of freshwater fish cultivation, in particular to an ecological cultivation method for grass carp. Background technique [0002] Grass carp belongs to the genus Grass carp of Cyprinidae, Cyprinidae, Yaluo subfamily. The common names of grass carp are: grass carp, grass carp, oil carp, grass carp, white carp, grass carp, mixed son, black herring, etc., inhabiting rivers and rivers in plain areas Lakes generally prefer to live in the middle and lower layers of the water and areas with many aquatic plants near the shore. It is lively, swims fast, and often feeds in groups. It is a typical herbivorous fish. Grass carp eats larvae, algae, etc. in the juvenile stage. Grass carp also eats some meat, such as earthworms and dragonflies. Because of its rapid growth, delicious meat, and wide source of feed, grass carp is one of the four major freshwater fishes in China. [0003] At present, most of the grass carp cult...

Problems solved by technology

These chemical reagents are easy to pollute the water body, interfere with the normal growth of fish, and there will be chemical residues on the fish body, which will cause serious harm to the human body after consumption

However, the existing grass carp farming is all about the abuse of unreasonable feed, which not only leads to poor water quality, reduced grass carp production, but also greatly reduces the quality of grass carp
