PROBLEM TO BE SOLVED: To visually show a fish point in response to the movement of a fishing device and enable an efficient fishing operation by the light emission of the device itself, when a fish detection sensor detects a fish shoal. SOLUTION: This fishing device 1 is provided with one or plural sound wave sensors 5 and with a light emitter 6 for visual displaying a fish shoal, when the sound wave sensors detect the fish shoal. When the light emitter 6 of the fishing device 1 thrown in water is lighted, it is found that there are fishes at the place and in the neighborhoods. When the light emitter does not light, the fishing device is moved to search a place in which the light emitter lights. Thus, the movements of the fishing device can be concentrated at a fish place, thereby permitting an efficient fishing.
