| 摘 要： | 为获取秘鲁外海茎柔鱼Dosidicus gigas栖息地的适宜温度指标,预测水温变化对茎柔鱼栖息地的影响,根据2006—2011年中国鱿钓船在秘鲁外海的茎柔鱼生产数据,并结合实测和通过卫星遥感技术获得的该海域海表温度数据,在作业次数和单位捕捞努力量渔获量(CPUE)基础上,采用海表温度适应性指数(Suitability index,SI)模型预测方法进行了相关研究。结果表明:随着水温的升高,茎柔鱼栖息地经向自西向东转移,纬向自北向南转移;产量较高的月份为7—12月,选取最佳适宜温度指标为19℃;发生厄尔尼诺现象时茎柔鱼产量下降,发生拉尼娜现象时产量则增加。

| Abstract: | The effects of changes in water temperature on habitat of Jumbo flying squid Dosidicus gigas off the coast of Peru were studied based on the production data of squid jigging vessel of China off the coast of Peru in the years of 2006-2011,combining with surface temperature data of observing and satellite remote sensing and using Suitability Index Model depending on work times and catch per unit effort(CPUE) in order to get the suitable temperature index and to predicte the change in temperature impact on habitats of Jumbo flying squid.The results showed that the habitats of Jumbo flying squid were moved from west to east in horizontal and from north to south in vertical with the warming sea temperature.The suitable temperature index in the month of high production was observed at water temperature of 19 ℃.The production of Jumbo flying squid was drawdown when the phenomenon of El Nino happened,and the production was increased when the phenomenon of La Nina was found. |
