| Electric fish screen | Mechanical Engineering | It consists of an electronic impulse generator which employs the industrial-type vacuum tube, the live electrode, and the ground conductor. The live galvanized pipe electrodes are suspended vertically to swing freely from an overhead beam or catenary cable supported by structural steel supports on each side of the canal. Random lengths of galvanized pipe strung on a cable and joined electrically by a copper wire are placed along the bottom of the channel to form the ground conductor. The fish which enter are stunned by shocks from electric screen and are carried back downstream towards fish traps, counting weirs, or entrance to fish ladders. Source: European Union.
