PROBLEM TO BE SOLVED: To achieve energy saving and safety while obtaining results of fishing in fishing squids by lighting a fishing lamp device on a squid-fishing vessel.SOLUTION: A light source 41 for emitting light including all the wavelengths of violet, blue, green, yellow, orange and red constituting visible rays, in which the energy ratios in the wavelengths of violet, green and orange are high, is used as the light source 41 for emitting the light in the fishing lamp device 14. The squid-fishing vessel 11 has the light source 41 disposed at the center of a cradle 32 of a squid-fishing device 13 in such a way that the angle can be adjusted. Squids are gathered and made to actively bite a bait by the light of a peculiar wavelength and by a clear shadow 62 formed under seawater.COPYRIGHT: (C)2012,JPO&INPIT【課題】イカ釣り漁船の上で集魚灯装置を点灯してイカを釣るときに、釣果を得ながらも、省エネと安全を図ることができるようにする。【解決手段】集魚灯装置14における光を照射する光源41として、可視光線を構成する紫、青、緑、黄、橙、赤すべての波長を含み、なかでも紫、緑、橙の波長のエネルギ割合が高い光を照射する光源41を用い、この光源41を、船舷に配設されたイカ釣り装置13の受け台32の中央部に角度調節可能に設けたイカ釣り漁船11。特異な波長の光と海中にできる明瞭な影62によって、イカの集魚をはかるとともに捕食を活発にさせる。【選択図】図2
