Abstract
Abstract A fishing net includes a photoconductive cable comprising a plurality of optical fibers having light-emitting portions, wherein said light-emitting portions are divided into a first group adapted to emit light having favorable influence upon fish and a second group adapted to emit light having an adverse influence upon fish. The direction of light emanating from said first group of light-emitting portions is counter to that of light emanating from said second group of light-emitting portions. Fish travel into the net influenced by the light of the first group and are discouraged from leaving by the light of the second group.
