ABSTRACT:
A gate is provided in a seine fishing net to allow sea mammals entrapped with fist in the net to escape. The gate is selectively inflated or deflated so that it may be raised to the surface or lowered, and is disposed in position in place of floatation devices at the upper extremity of a section of the net. A ribbon net is connected to one side of the gate and is drawn between schools of sea mammals and entrapped fish to allow the sea mammals to escape through the gate while discouraging the fish from escaping the seine net once the seine net has been set.
