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。
By using methods of cluster and correlation analysis, the correlation of the catch per unit effort (CPUE) to the sea surface salinity and the seawater temperatures of different depths were studied.
利用聚类和相关分析方法,研究了单位捕捞努力量渔获量与表层盐度及不同水层水温的关系。
A new method for estimating fish natural mortality coefficient (m), based on the extended survivors method, using a catch-at-age data and an abundant index (catch per unit effort, CPUE) was proposed.
基于扩展残存资源量法,提出一种根据分年龄组渔获量以及资源量指数(单位捕捞努力量渔获量,CPUE)求算鱼类的自然死亡系数(M)的新方法。
