China is wide in territory and numerous in reservoirs. With the development of society, more and more reservoirs will be transformed into drinking water source areas. In order to keep ecological balance and improve the quality of diet, drinking water and living environment of urban residents. People put a large amount of fish seeds in a reservoir. The method can generate great economic benefit and supplement the management expense of the reservoir, and particularly can timely feed the microorganisms which are easy to generate blue algae in the reservoir water and are generated by rotten roots, fallen leaves and other plants through the fish school so as to keep ecological balance. The water quality of the reservoir meets the drinking water standard. On the other hand, in flood season, a large amount of plant dead branches, fallen leaves and domestic garbage of residents around the reservoir can be gathered at a flood discharge opening along with water flow and spread in a downstream urban river through the flood discharge opening, and the living environment of residents along the edge is seriously influenced. Cleaning after diffusion is more labor intensive and costly. Especially, the economic loss of the fish in the group escaping from the reservoir is millions in a few and tens of millions in a large number every year. Meanwhile, the ecological balance of reservoir water areas and the quality of drinking water sources are seriously influenced.
In order to intercept the fish schools and floaters, the conventional fishing net is used on the outer side of the dam body to cross the whole water surface for interception, however, as the water area on the outer side of the dam body is generally wide and deep, the bottom surface is uneven and difficult to fix, the construction difficulty is high, once the water level rises in a flood season, large and small floaters are gathered on the intercepting net crossing the whole water surface, the generated front pressure easily damages the intercepting net, the service time is greatly shortened, and the fish schools are greatly lost. Therefore, these interception nets need to be replaced frequently, the investment is very large, and the effect is very poor. So that a large part of reservoirs directly abandons interception.
