The net comprises a network of criss-crossing members forming a net surface. The criss-crossing members meet at net member junctions. The net has a net mouth having an elastic band. The net mouth is extended over the intake tube mouth, and the elastic band tightens onto the intake tube outer wall. Spacers extend perpendicularly inward from the net member junctions to space the net surface from the intake tube outer wall.
