摘要: 根据2010—2014年南海外海鸢乌贼(Sthenoteuthis oualaniensis)渔业生产数据,结合海洋遥感所获得的海表面温度(sea surface temperature, SST)和海表面高度异常(sea surface height anomaly, SSHA)数据,采用外包络法基于单位捕捞努力量渔获量(catch per unit of effort, CPUE)计算适应性指数(suitability index, SI),用算数平均法建立基于环境因子的栖息地适应性指数(habitat suitability index, HSI)分析模型。结果表明:南海外海鸢乌贼中心渔场的最适SST范围为26.4~29.6 ℃,最适SSHA范围为-0.014~0.114 cm;当HSI>0.6时,作业次数比率为77.99%,平均CPUE为4.13 t·d-1。研究指出,基于海表面温度和海表面高度异常的栖息地适应性指数模型能够较好地表征鸢乌贼的中心渔场,准确率超过77%。

Abstract: According to the data of purpleback flying squid (Sthenoteuthis oualaniensis) fishery data during 2010-2014 in the open South China Sea, combined with sea surface temperature (SST) and sea surface height anomaly (SSHA) data from ocean remote sensing satellites, and catch per unit of effort (CPUE) as the fishery density index to calculate suitability index (SI) by external envelope method, habitat suitability index (HSI) model was built by using  arithmetic mean method. The results showed that optimal ranges of SST and SSHA in the main grounds of the open South China Sea were 26.4-29.6 ℃ and -0.014-0.114 cm, respectively. When HSI value was more than 0.6, percentage of fishing times reached 77.99% and the average CPUE was 4.13 t·d-1. Our results indicated that the HSI model based on SST and SSHA could denote the main fishing grounds of purpleback flying squid, and the accuracy of the model was above 77%.
