Because the fish basket is a cylindrical fishing tool, it is generally about 70 cm long, the net is supported by three rings, and the diameter is about 40 cm. There are fish inlets with the size of 10 cm at both ends, and the inlets are inward.

The way to use the fish basket is to put this fishing tool directly in the gap of the stream, and then the huge opening will make it easy for fish to enter, but when you want to escape from it, you will find that its exit is very narrow and basically you can't get out.
