ABSTRACT:
There is disclosed a footrope construction for use with a bottom trawl generally comprising a conical net having side wings to herd fish into the mouth of the net, flotation devices attached to the upper part of the mouth of the net to provide hydrodynamic lift, and wire ropes attached to the side wings of the net and adapted to be attached to a vessel to spread the net horizontally. The footrope construction comprises a series of rubber straps maintained substantially in the vertical at a specific vessel speed, thus allowing the strap to lightly contact the ocean bottom and create a mudcloud which will provide a visible deterrent for the regular fish entering the wings of the trawl to escape under the net while passing over the shellfish without causing damage and without capturing them in the net.
