Abstract

The device is for removing live fish from a pool. A conveying screw has a section of grating type screw windings enclosed by a cylindrical drum at its inlet end and a section of feed windings arranged on the same extended drive shaft and enclosed by a cylindrical casing tube. The fish passage extends from a hole in the casing tube and passes around the conveying windings and a deflector at the last grating-type screw winding. The drum is of transparent material.
