摘要
根据头足类对光反应的最低背景照度(0.01 lx),用点光源海面照度计算方法,对鱿钓渔船不产生灯光干扰的合适照度间距进行分析,并建立了大型鱿钓渔船抛锚位置与相邻渔船的合适作业间距计算公式为LZ=(72.9652+10.7151h1)P01.2535+(72.9652+10.7151h2)P02.2535+225。根据该公式计算可得,集鱼灯总功率均为360 kW、灯高为7.0 m的两艘大型鱿钓渔船的合适作业间距应为0.83n m ile。
The available illuminate distance between two squid jigging vessels was analyzed on the base of low background illumination for some cephalopod species (0.01 lx), with point source model of illumination of sea surface. And the formula of the available operation distance from the anchoring position to the near vessel can be described as LZ=(72.9652+10.7151h1)P1^002535+(72.9652+10.7151h2)P2^0.2535+225. With the formula, the nearest operation distance of two large - scale special squid jigging vessels which lamp height above water is 7.0 m and each has 360 kW out power of 0.83 nautical mile.
