    We attempted the development of highly efficient fishing lights using LEDs for saury fishing. Considering the spectral luminous efficacy characteristic of a Pacific saury, LED fishing lights were fabricated. Transmission properties in sea water in LED fishing lights were investigated, and it was found that the fabricated LED fishing lights sufficiently can be utilized even in sea water. Furthermore, we attempted 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.
