In the saury fishing, incandescent lamps are usually used for a fishing light. However, there are problems of the conventional fishing lights using incandescent lamps . First, electric power consumption is large. And the incandescent lamps are very inefficient, because much infrared light is included. Furthermore, life time is short and there is a problem of a lot of heat generation. Therefore, we attempted the development of highly efficient fishing lights using LEDs for saury fishing. We designed the combination of various LEDs for a fishing light, based on the spectral luminous efficacy of a Pacific saury. We performed the saury-fishing experiments by using the LED fishing lights, and comparable catch of Pacific saury was achieved by approximately 55% electric power by using both LED poles and incandescent lamp poles. Moreover, we attempted the development of LED fishing lights for squid, and it was found that comparable catch was achieved by lower electric power than that of conventional fishing lights.
