| 摘 要： | 本文根据１９８９－１９９４年拖网上应用萤光网片的对比试验，通过划分昼夜效应夜时限区选取对比网次，对萤光拖网作业中对不同渔获对象的形态类别，鱼类的生态类群和不同鱼种的昼，夜捕捞效应进行研究。以期提高其作业效率，可供在生产实践中参考应用。

| Abstract: | Based on the experimental data obtained from 1989 to 1994, by deviding the span into daytime (05.00AM ~ 0500PM) and nighttime (0800PM ~ 0500AM ) and then selecting the number of comparing-test correspondingly, the author here studied respectively the daytime catch efficiency and nighttime catch efficiency of trawl constructed by fluorescent twine in different morphology, different ecology and different species of catch targets. It' s of valuable in improving the catch efficiency and can be applied in the product activity. |
