Abstract: In order to provide a basis for the practical application of LED fish-gathering lights for fisheries, taking “Zhedaiyu 13461” fishing vessel as an example, the underwater illuminance of the fishing lamps with different total power, different installation angle and different installation height was calculated using the measured optical characteristics of LED fishing lamps, fishing vessel configuration parameters, annual average sea surface wind speed and chlorophyll concentration data in the East China Sea, and using Monte Carlo model. The results showed that within 45 m from the sea surface, the illuminance at the wavelength of 400-600 nm was not attenuated to zero, which is beneficial to the trapping of squid and mackerel; different lighting configurations had basically the same effect on the effective trapping water volume of mackerel and squid; the maximum trapping water volume, trapping distance and trapping depth were increase with the increase in power in the fishing vessel total power of 18, 27 and 36 kW, and the increase in power being beneficial to fish trapping to a certain extent, but with the increase in power, the increase in amplitude of maximum effective trapping water volume and trapping distance was decreased; at the installation angle of 45°, 60° and 75°, the maximum effective trapping volume and distance were increased significantly, and the trapping depth decreased with the increase in angle; at the lamp height of 5, 6 and 7 m, the maximum effective trapping volume and distance increased with the increase in lamp height, and the trapping depth did not change significantly. The findings indicated that the total power of LED fishing lamps on the “Zhedaiyu 13461” fishing vessel is 36 kW, the lights height of 6-7 m, and the installation angle of 60°-75°.
