Problems solved by technology

[0010] The present invention aims to solve the problems in the prior art that the feed feeding method under the polyculture mode of aquaculture will inhibit the growth of bacillus and lactic acid bacteria in the water body, and the harmful substances in the water body are likely to be produced, causing poisonous damage to the cultured fish. A precise combined feeding method for adjusting water quality under the polyculture mode in aquaculture can make Bacillus and lactic acid bacteria in the water body the dominant bacteria and prevent the production of harmful substances

Embodiment 1

[0037] A precise combined feeding method for adjusting water quality in a mixed culture mode in aquaculture, the described feeding method is at noon every day, each feed to be fed in the mixed culture mode is fed by the following method:

[0038] A. High and low protein feeds are used together in the whole breeding process

[0039] During the whole breeding process of the polyculture mode, the high-protein feed and the low-protein feed of all kinds of feeds are mixed together and fed at the same time, and the weight ratio of the high-protein feed in the early stage and the low-protein feed in the late stage is 1:1;

[0040] B. Adjust the carbon-nitrogen ratio in the mid-term of breeding

[0041] In the mid-term of polyculture mode, that is, when the breeding starts 4 months ago, adjust the weight ratio of the high-protein feed in the early stage to the low-protein feed in the late stage to 1:2; Hey;

[0042] C. Adjust water quality in the later stage of breeding

[0043] In...

Embodiment 2

[0045] A precise combined feeding method for adjusting water quality in a mixed culture mode in aquaculture, the described feeding method is at noon every day, each feed to be fed in the mixed culture mode is fed by the following method:

[0046] A. High and low protein feeds are used together in the whole breeding process

[0047] During the whole breeding process of polyculture mode, all types of feeds are mixed with high-protein feed and low-protein feed in the later stage and fed at the same time, and the weight ratio of high-protein feed in the early stage and low-protein feed in the later stage is 1:3;

[0048] B. Adjust the carbon-nitrogen ratio in the mid-term of breeding

[0049] In the mid-term of the mixed culture mode, that is, when the culture starts 5 months ago, adjust the weight ratio of the high-protein feed in the early stage to the low-protein feed in the late stage to 1:4; Hey;

[0050] C. Adjust water quality in the later stage of breeding

[0051] In t...

Embodiment 3

[0053] A precise combined feeding method for adjusting water quality in a mixed culture mode in aquaculture, the described feeding method is at noon every day, each feed to be fed in the mixed culture mode is fed by the following method:

[0054] A. High and low protein feeds are used together in the whole breeding process

[0055] During the whole breeding process of polyculture mode, all types of feeds are mixed with high-protein feed and low-protein feed in the later stage and fed at the same time, and the weight ratio of high-protein feed in the early stage and low-protein feed in the later stage is 1:2;

[0056] B. Adjust the carbon-nitrogen ratio in the mid-term of breeding

[0057] In the mid-term of polyculture mode, that is, at 4.5 months from the start of breeding, adjust the weight ratio of high-protein feed in the early stage to low-protein feed in the late stage to 1:3; Hey;

[0058] C. Adjust water quality in the later stage of breeding

[0059] In the later s...

Abstract

The invention relates to a precise combined feeding method for regulating water quality in aquaculture, and belongs to the technical field of the aquaculture. The precise combined feeding method for regulating the water quality in the aquaculture includes steps: using high and low protein feed in mixing mode during the whole aquaculture process, regulating a carbon-nitrogen ratio in the medium period of the aquaculture, and regulating the water quality in the later period of the aquaculture. By using the precise combined feeding method for regulating the water quality in the aquaculture, the water quality can be regulated well, bacilli and lactic acid bacteria in a water body become dominant bacteria, fishes can grow well and quickly by throwing the feed in the later period of the aquaculture, a culture cycle is shortened, yields and efficiency are increased, and a feed coefficient is reduced.

Description

technical field [0001] The invention relates to a feed feeding method, more specifically, the invention relates to a precise combination feeding method for adjusting water quality in a polyculture mode in aquaculture, which belongs to the technical field of aquaculture. Background technique [0002] An important development direction of the aquaculture industry is "polyculture". The main types are: polyculture of various fish, polyculture of fish and shrimp, polyculture of fish and turtle, polyculture of fish and crab, etc. However, polyculture raises new issues regarding feed formulation, feed production and feed feeding techniques. [0003] The first is the problem of feed formula setting. In a pond, fish with different nutritional requirements are "polycultured", and fish and shrimps with greatly different nutritional requirements are "polycultured". In terms of feed nutrient level setting and feed formula preparation, for the "polyculture" mode In the same pond, at lea...
