Wind force and current can increase CPUE in the case of lower trawling speed.
在拖速不足的情况下，借助风力和海流可以提高CPUE的产量；
Firstly, GLM was applied to evaluate impacts of temporal, spatial, environmental, fisheries operational variables on the CPUE, and the significant factors.
首先应用GLM模型评价时间、空间、环境以及捕捞渔船参数对CPUE的影响，并确定显著性变量。
Overall, in 2007, there was an obvious seasonal change in the spatiotemporal distribution patterns of Chilean jack mackerel fishing grounds, and the CPUE value had a larger fluctuation range.
初夏渔场有所南撤。总的来说，智利竹筴鱼渔场时空分布具有明显的季节变化，CPUE值波动范围较大。
