Aquaculture method

Abstract

An aquaculture method includes following steps: selecting a pond with a flat bottom; reserving sludge of 25-30cm in thickness at the bottom of the pond; releasing 500-700 black carps of 600-700g per mu into the pond in late March; releasing 300-500 crucian carps of 50-100g per mu into the pond in early April; releasing 300-500 bighead carps of 80-350g per mu into the pond in middle May; releasing 600-800 crucian carps of 60-280g per mu into the pond in late May; releasing 300-500 grass carps of 120-400g per mu into the pond in early June. Different aquatic product species are released into the pond scientifically, reasonably and sequentially according to growing characteristics for breeding, so that the aquatic product species are avoided eating each other, survival rate of the aquatic product species is increased, production value, yield and economic benefit of aquaculture are increased. Environment needed by the aquatic product species is provided, so that ecological breeding of aquatic products is maintained.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an aquaculture method. Background technique [0002] With the continuous development of the economy and the substantial improvement of people's living standards, people's demand for aquatic products continues to increase, and the quality requirements for aquatic products are also getting higher and higher, which also promotes the rapid development of aquaculture technology. Aquaculture refers to the production activities of breeding, cultivating and harvesting aquatic animals and plants under human control. It mainly includes the whole process of growing aquatic products from seedlings under artificial breeding management. Aquaculture includes extensive cultivation, intensive cultivation and high-density intensive cultivation. Extensive culture is to put seedlings in small and medium-sized natural waters, and to grow aquatic products completely by natural bait, such as fish ...

AI Technical Summary

Problems solved by technology

However, there is no staged introduction of aquatic species, resulting in the frequent occurrence of small meals of different aquatic species, which is not conducive to the common harvest of aquaculture, affects the economic benefits of aquaculture polyculture, and also makes the nutrients of the remaining aquatic species single

Moreover, there is no reasonable control of the pond feeding environment, so that the residual bait, fish feces and excreta cannot be discharged in time, resulting in deterioration of water quality and hindering the output value of aquaculture.
