摘　　要：为进一步验证LED水上集鱼灯的使用效果,将300W型LED集鱼灯安装到"宁泰61"鱿钓船,赴东南太平洋秘鲁外海茎柔鱼渔场进行实际生产,与使用2 kW型金卤灯的"宁泰62"鱿钓船进行对比试验,记录相关生产数据并对作业船周围集鱼灯形成的海面上、海面下光场及光谱进行实地测量。结果表明:右舷50盏LED集鱼灯在海面上照度为0.1lx的离船最远距离可达35 m,比使用50盏2 kW型金卤灯时少10m;50盏LED集鱼灯与50盏2 kW型金卤灯在海水中的照度分布接近;LED集鱼灯在海水中的光谱衰减速率明显小于金卤灯。使用LED集鱼灯不仅能大幅度减少燃油消耗,且诱鱼效果接近传统高功率金卤灯,能够在实际作业中发挥作用。To verify catch performance of LED fish-attracting lamp in actual scene,contrast test was made.We equipped LED lamps（ 300 W rated power each） on squid jigging vessel of Ningtai 61 and also sent another squid jigging vessel of Ningtai 62 equipped with Metal Halide Lamps（ MHL） as contrast. Both vessels fished in southeast pacific ocean off the coast of Peru at same time. We recorded the yield and fuel every day,meanwhile we tested illumination and spectrum around ship. After comprehensiveness analysis,we reached the conclusion： the equal illumination curve of 0. 1 Lx of LED lamps could reach 35 m in vertical direction,10 m distance less compared with MHL; In vertical direction,illumination distribution of LED is analogous to MHL.LED spectrum distribution power attenuation rate underwater was less than MHL. LED fish lamp becomes really adequate,not just reducing fuel consumption but also having same catch performance compared with MHL light in the process of fishing. LED fish-attacting lamp can be a new light source for replacing traditional fish lamp.
