Problems solved by technology

At present, although there is a polyculture method for freshwater fish farming, the fish species and the amount of stocking in the polyculture are different. Stocking different types of fish in the same pond may also bring negative effects: that is, it will affect other fish. Seed yield

Embodiment Construction

[0011] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing:

[0012] Such as figure 1 Shown, a kind of culture method of freshwater fish comprises the steps:

[0013] S1. Preparation of fish ponds: The area of ​​high-yield ponds is 3,000 square meters (about 5 mu). If conditions permit, the aquaculture area of ​​the ponds can be appropriately expanded, so that the fish meat tastes better. The depth of water in the pond is 2.5 meters. A mechanical aerator is set in the pond and new water with more dissolved oxygen will be added frequently, so as to improve the dissolved oxygen condition of the near-bottom water and improve stocking and output. Due to the abundance of plankton and suspended organic matter in high-yield ponds, photosynthetically active radiation is generally rarely transmitted to the water layer below 0.5 meters, so the survival rate of fish is high, and there is a rich supply of fish feed. The ...

Abstract

The invention discloses a cultivation method of freshwater fish. The cultivation method comprises the following steps: S1, preparing a fish-farming pond; S2, putting on mixed culture fish: taking 30kg of 70-80 grass carp with the weight of 250-750g, 13kg of 150-200 grass carp with the weight of 50-100g, 3.4kg of 50 megalobrama amblycephala with the weight of 50-100g, 0.9kg of 100 megalobrama amblycephala with the weight of 7-10g, 14.6kg of 50 silver carp with the weight of 250-400g, 13kg of 250 silver carp with the weight of 50-100g, 6.8kg of 20 bighead carp with the weight of 250-500g, 1.8kg of 30 bighead carp with the weight of 50-100g, 18kg of 250 carp with the weight of 50-100g, and 1-1.5kg of 2-10 black carp with the weight of 50-750g, and putting all fish into the fish-farming pond; S3, harvesting the adult fish. The method is characterized in that six kinds of freshwater fish are together placed in the same pond for mixed culture and increased in yield by controlling different breeding quantity.

Description

technical field [0001] The invention relates to the technical field of freshwater fish cultivation, in particular to a method for cultivating mixed freshwater fish. Background technique [0002] With the improvement of people's living standards, healthy diet has attracted more and more attention. As a food rich in protein and various nutrients, fish is very popular. At present, although there is a polyculture method for freshwater fish farming, the fish species and the amount of stocking in the polyculture are different. Stocking different types of fish in the same pond may also bring negative effects: that is, it will affect other fish. The yield of the species. Therefore, it is a problem that the freshwater fish farming industry pays close attention to in order to find a polyculture method with high yield for various fishes. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a ...
