| 摘 要： | 月相是影响光诱鱿钓作业效率的重要因素之一。通过对1995~2000年北太平洋8~10月150°E~165°E柔鱼盛渔期的生产统计分析,各月月相在朔期间的产量分别为望期间产量的1.16、1.53和1.20倍,平均日产量分别增加0.38 t/d、0.9 t/d和0.21 t/d。经过GAM模型分析,月相对日产量的影响是显著的,其PC f值均在0.14以下,模型分析结果满意。

| Abstract: | The month phase is an important factor affecting the fishing efficiency in the squid jigging fisheries.Based on the production statistics of main fishing seasons in the North Pacific Ocean during August-October from 1995 to 2000,the output of new moon period in each month was 1.16,1.53 and 1.20 times as many as that of full moon period respectively,the average daily output was 0.38t/d,0.9t/d and 0.21t/d more than that of full moon period respectively. The GAM model analysis indicates that the effect of moon phase on daily output was remarkable with its PCf value below 0.14,so the analysis result is satisfied. |
