【摘要】 根据2004年9-12月阿拉伯海北部公海海域鸢乌贼资源的调查和渔获统计资料,采用效能比方法,对鸢乌贼资源密度指标CPUE值进行了估算。结果发现,调查海域的鸢乌贼资源密度较高,其CPUE值为0.2~8.3尾/(线.h),CPUE优势组为1.0~4.0尾/(线.h),约占总站数的63.1%,总体平均CPUE值为2.22尾/(线.h)。资源密度的随海域而不同。高于2尾/(线.h)的CPUE值分布在12°N,58~62°E;14~16°N,59~61°E;18~20°N,62~64°E海域。更多还原

【Abstract】 Based on the resource inversigation and catch data of Symlectoteuthis oualaniensis in open seas of the northern Arabian Sea during September to December 2004,the resource density index CPUE values were estimated by using the efficiency ratio method.It is shown from the estimation results that the resource density of Symlectoteuthis oualaniensis in the investigation area was higher with a CPUE value ranging from 0.2 to 8.3 squids per line per hour,the dominant CPUE value group was in the range 1 to 4 squids per line per hour,which accounts for 63.1 percent of the total number of fishing stations, and the ensemble average CPUE was 2.22 squids per line per hour.The resource densities varied with different sea areas,and the CPUE values higher than 2 squids per line per hour were distributed in the sea areas of 12 °N,58 °E to 63 °E,14 °N to 17 °N,59 °E to 61 °30 ′E and 19 °30 ′N to 21 ° N,62 °30 ′E to 64 °E.更多还原
