2种LED灯的蓝圆鲹和竹荚鱼渔获比较

Comparison between the catches (Trachurus japonicus and Decapterus maruadsi) around two LED lamps

  • 摘要: 为了探索节能减排的海洋捕捞作业方式,在中国沿海海域做了白光(偏绿光)发射二极管(LED)水下灯和蓝紫光LED水下灯集鱼试验。对比2种等光能LED集鱼灯周围蓝圆鲹(Decapterus maruadsi)和竹筴鱼(Trachurus japonicus)的渔获,对渔获数据进行t检验分析表明,白光LED灯对蓝圆鲹的光诱效果显著优于蓝紫光LED灯;白光LED灯对竹筴鱼的光诱效果极显著优于蓝紫光LED灯。海上试验结果证实,在实验室水槽中所得的光诱鱼试验结果对海洋捕捞实践具有很好的指导作用。

     

    Abstract: We carried out a series of fishing experiments with two sets of Light Emission Diode (LED) lamps in China coastal waters to explore energy-saving fishery. Comparing the catches of Decapterus maruadsi and Trachurus japonicus around the white-green LED lamp to the catches around the blue LED lamp with t-test analysis, we confirm that the white-green LED lamp is superior to the blue LED lamp for catching D.maruadsi and is vastly superior to the blue LED lamp for catching horse mackerel. Results confirm that light trapping fish experiments findings in laboratory flume can be good guidance to marine fishing practice.
