A fish screen is designed to prevent fish from swimming or being drawn into an aqueduct, cooling water intake, intake tower, dam or other diversion on a river, lake or waterway where water is taken for human use. They are intended to supply debris-free water without harming aquatic life. Fish screens are typically installed to protect endangered species of fishes that would otherwise be harmed or killed when passing through industrial facilities such as steam electric power plants, hydroelectric generators, petroleum refineries, chemical plants, farm irrigation water and municipal drinking water treatment plants. However, many fish are killed or injured on screens or elsewhere in the intake structures.

A kind of gold pompano fry sorting device
The utility model discloses a kind of gold pompano fry sorting devices, comprising: water tank, sorting component and flow adjusting component;Sorting component includes multiple fish screens;Multiple fish screens are sequentially spaced in water tank, to sequentially divide the inside of water tank into fry entering area and multiple fry sorting areas;Fry entering area is used to put the gold pompano fry to be sorted, in multiple fish screens, the mesh of fish screen is smaller when it is farther from fry entering area;Flow adjusting component is used to adjust the water flow direction of water tank, to form water flow from the farthest fry sorting area to fry entering area in water tank;The farthest fry sorting area is farthest from fry entering area. That is to say, the present gold pompano fry sorting device sorts using the habit of gold pompano fry swimming against water, so as to guide gold pompano fry to actively participate in sorting process by water flow from the farthest fry sorting area to fry entering area in water tank, this way not only reduces gold pompano fry damage rate, but also improves sorting efficiency, while also improves sorting accuracy.
