PROBLEM TO BE SOLVED: To provide a white bait fishery method capable of fishing white baits which are fry efficiently with the aligned size, and with little contamination of fish which is not a fishery object, and saving power consumption at that time.SOLUTION: In a white bait fishery method, white bait-gathering light in blue to green having a maximal value in a wavelength region of 450-540 nm is radiated in the water, in the flashing state at the frequency of 10-50 Hz.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】稚魚であるシラスを、大きさが揃った状態でかつ漁獲対象でない魚類の混入を少なくしながら効率良く漁獲でき、しかも、その際の消費電力を節約できるシラス漁獲方法を提供する。【解決手段】水中において450~540nmの波長領域に極大値を有する青色~緑色のシラス蝟集用光を、10~50Hzの周波数で点滅させながら放射することを特徴とするシラス漁獲方法。【選択図】図3
