摘要
集鱼灯在现代光诱渔业中起到重要作用,其种类、功率、配置方式等选择都会对诱集效果产生一定的影响。为了更好的研究集鱼灯配置对水下照度分布的影响机制,以便在捕捞作业中应用。本文以国内近海灯光围网渔船"浙岭渔23391"灯布置参数,对该船的单侧集鱼灯系统水中照度分布进行分析计算,分析结果表明:渔船集鱼灯总功率保持不变,增加集鱼灯离水高度时,有效诱集水体体积也增加;渔船集鱼灯总功率为84 kW,10 lx的等照度曲线水平方向最远在55 m左右,水深方向不超过40 m;0.1lx照度最深可约至70m水深,最远为200m左右。功率调整至100kW,有效诱集水体体积仅提高7%;集鱼灯间隔增加,水下照度分布变化不显著。该研究为明确不同配置方式集鱼效果以及水中光照分布等情况,进行了集鱼灯的实船试验和分析,以期能给渔业从业者和相关研究人员提供参考。
Fishing lamp plays an important role in the modern fishery, how to choose the type,power and collocation, etc. will has a certain impact on the trapping effect. In order to learn the impact of underwater illumination distribution effected by fishing lamp better, which could be used in fishing operations. Based on the parameter of fishing lamps assigned on the offshore light seine fishing boat named Zhe Ling Yu23391, the underwater Illumination created by the unilateral fishing lamps was analyzed and calculated. The result shows that when keeping the total power unchanged, the effective volume of water will increase while the high of lamps increase. When the total power is 84 kW, the illumination value 10 lx is about 55 m far in horizontal direction while in depth direction it is no more than 40 m. The illumination value 0.1lx can arrive about 70 m underwater while it can reach about 200 m in horizontal direction. The total power raised to 100 kW,it will only increase 7%. When the interval of the lamps increases, the change of illumination underwater is not significant. The purpose of study is to clear the effect of fish collection and light distribution underwater in different allocation, in order to provide a reference to fisheries practitioners and researchers.
