本文报道了将萤光网线应用在光诱鱿鱼敷网的底网网衣及其近网口部位的试验,结果表明,这种做法能扩大该网具作业区域内的有效集鱼范围,提高诱引捕捞对象入网的效果。根据对2000年7月-2000年10月的海上生产472网次对比资料统计及比较:萤光网的夜平均产量增加10.6％,夜平均产值增加12.1％以上;由于渔场作业水深不同、渔获组成不同和捕捞对象不同,萤光网的捕捞效应也发生变化。本文还讨论了不同捕捞对象的趋光性能和背景光的影响等问题。
This paper reports the experiment of applying fluorescent mesh wire to the net netting and its near net mouth of light-induced squid netting. The results show that this method can expand the effective range of fish-collecting in the working area of netting, Catch fishing target into the network effect. According to statistics and comparisons of 472 net production data of offshore production from July 2000 to October 2000: the nighttime average output of fluorescent net increased by 10.6% and the average night output value increased by 12.1% or more; due to the different operating depths of fishing grounds, the catch Different composition and different fishing targets, fluorescent net fishing effect also changed. This article also discussed the phototactic properties of different fishing objects and the impact of background light and other issues.
