Isoilluminance lines produced by two underwater lamps were described with relation to the displacement of lights by current, the extinction of lights, the arrangement of lights and the reflection at water surface.Under the condition of this irradiance, the trace of swimming behavior of fish was estimated by the method of computor simulation, and was described by X-Y plotter.The result suggests that it is a reasonable motion for the fish to swim lazily or zigzag under the fish lamp, and it is necessary to consider the operating area of the fishing gear with relation to the lamp fishing.
