| 摘 要： | 为分析LED集鱼灯是否适用于南海近海灯光罩网渔业,本研究进行了3种LED集鱼灯与1种传统金卤灯的生产对比试验。研究发现:(1)试验使用的LED白光灯的相对光谱功率分布有2个波峰,分别在蓝光波段,绿光、黄光波段,LED绿光灯有1个波峰为绿光波段,LED蓝光灯有1个波峰为蓝光波段,金卤灯有多个波峰,峰值波长主要在红光波段;(2) 3种LED集鱼灯的渔获率均高于金卤灯,其中LED白光灯渔获率优势明显;(3) 4种集鱼灯渔获的共同优势种为中国枪乌贼(Loligo chinensis),其中LED白光灯的渔获率明显高于其他灯具;(4)单因素方差分析结果表明LED白光灯与金卤灯捕获的中国枪乌贼的胴长、体质量均无显著性差异。研究认为LED灯尤其是LED白光灯适用于南海近海灯光罩网渔业。

| Abstract: | The study carried out the fishing tests of 3 kinds of LED lamps and 1 kind of traditional metal halide lamp to analyze if the LED lamp was suitable for inshore falling-net fishery of South China Sea. The results show that:(1) there are two peaks in the relative spectral power distribution of white light LED used in the fishing test, and two peaks are in blue bands, green and yellow bands respectively; green light LED has one peak and the peak is in green bands; blue light LED has one peak and the peak is in blue bands; metal halide lamp has multiple peaks and the peak wavelength is mainly in red bands; (2) The catch rates of 3 kinds of LED lamps are all higher than metal halide lamp, and white light LED has obvious advantages; (3)Loligo chinensis is the common dominant specie among 4 kinds of lamps, and the catch rate of white light LED is significantly higher than the other 3 kinds of lamps; (4) one-way analysis of variance shows that there is no significant difference in the mantle length and weight of Loligo chinensis between individuals caught by white light LED and metal halide lamp. The study suggests that LED lamp, especially white light LED is suitable for inshore falling-net fishery. |
