| 摘 要： | 采用GIS定性分析和数值分析的方法,研究了印度洋大眼金枪鱼延绳钓钓获率与水温的 关系。结果表明,大眼金枪鱼延绳钓高钓获率的出现与印度洋加权水温大面分布存在明显的相互 关系,大眼金枪鱼的渔获适温在14～17℃间。建议测量200m水深处的水温作为海上生产时的参 考。

| Abstract: | The paper studied the relationship between water temperature and hooking rate of Thunnus obesus. GIS qualitative analysis and Numerical analysis were conducted. Overlays of high hooking rate and water temperature were created by GIS tool. The results show that the distribution of high hooking rate is related to change of water temperature, and the optimum water temperature for angling the Thunnus obesus ranges from 13 ℃ to 17 ℃. Furthermore, the paper suggests to measure the water temperature in 200 m layer during the operation. |
