Background

The aquaculture yield of China accounts for more than 70% of the total world yield, the aquaculture yield is the only country in the world with the yield exceeding the fishing yield, and the aquaculture industry is increasingly large in scale.

With the increasing world population, water resources can quickly become a factor for limiting a plurality of industries, the nutrition cost required by food production is further increased, the demand of southeast Asia countries on high-quality water products is greatly increased, the current situation of the fishing industry is kept or the fishing industry is in a descending trend, and the cultured aquatic products occupy the main market. Meanwhile, the water cost of agriculture, especially aquaculture industry, is increased, and the environmental pressure is increased. The biggest challenge in the 21 st century agricultural production is to produce more than 3 times the product using less resources. World bank global fishery program-2030 fishery project preliminary: the world aquaculture amount must be increased by 100% in 10-15 years in future to meet the increasing demand of people on aquatic products.

Pond culture, reservoir culture is the traditional aquaculture mode of china all the time, but these aquaculture modes are mostly put in the breed with batch fry simultaneously, because the fry that can lead to batch to put in is not of uniform size in the difference of the free growth progress of fry, and the habit of ingesting of the fish of equidimension is different, lead to the competition aggravation between the fish from this, be unfavorable for the growth reproduction of fish, simultaneously when salvaging and selling, generally all select the fish of equidimension, in prior art, because the fish are not of uniform size, the fish that leads to salvaging out has big or small, too little fish can only be put away again, but the salvage process leads to the fish body injured or receive the frightening easily, influence the growth of fish, simultaneously for unable control aquaculture environment.
