All data were processed using software ArcGIS, SPSS, and SQL Server. To overlay digital SST isoline with topology and normal Kuroshio path line, the data of Kuroshio path variation from 1990 to 2001 in 32day2span were obtained, and results were validated by comparing to the Kuroshio path charts. The Kuroshio path at 152day2interval is coincident with the 32day2interval path in the last same period. During the period of 1990 to 2001, Kuroshio bended in different scale and pattern, those noticed were : two large bendings in 1990 1991 and 1999 2001, two,quasi2bendings in January to October 1997 and June 1998 to May 1999, and 5 time small bendings in May 1992, April to October 1993, May to July 1997, December 1995 to March 1996, and November to December 1996. 1997 and 1998 were the years of quasi2bending of Kuroshio occurred, corresponding to the highest CPUE val2 ue. 1996 and 1999 were the years of small Krushio bending occurred, corresponding to high yearly CPUE value. In 2002, the Kuroshio path was straight, which was matched by yearly low in the CPUE. Year 2000 and 2001 were the period when large Kuroshio bending showed, the corresponding CPUE, therefore, was the lowest.
122 36 Between 1995 and 2001, the monthly CPUE was high during which the Kuroshio path was often in Ctyped me2 ander ( several types of Kuroshio meander were defined in the Section 2. 1). When the monthly CPUE remained high for more than three months, the corresponding Kuroshio path alternated between bending type and straight type. Between 1995 and 2001, when 32day2spanned CPUE values were 4. 0 6. 5, the bending was more common than straight ones, in mostly C type or CD type. When 32day2spanned CPUE was between 3. 0 4. 0, the Kuroshio path were generally straight type, but many were transitional ones between straight and bended. When the value were 2. 0 3. 0, the occurrence of straight type is higher bended type ; When 32day2spanned CPUE of Ommas2 trephes bartrami is less than 1. 0, the occurrence of straight type is much higher bended type. Based on the data in 1995 and 2001, the CPUE values in 32day interval reflected the meandering type of the Kuroshio. Generally speaking, the greater the CPUE is, the more frequent bending occurred. Specifically, between 4. 0 6. 5, the bending was very often ; between 3. 0 4. 0, bending events were slightly more than straight ones, with many transitional types ; between 2. 0 3. 0, straight type were more frequent than bending ones ; and between 1. 0 2. 0, mostly straight type. Distance data from 30 points on the Kuroshio path to baseline in 152day2interval was obtained using ArcGIS software. 302group distance data and 152day2interval CPUE of Ommastrephes bartrami was analyzed using SPASS software, based on the data analysis, the authors summarized : In 1998, there were 13 places on Kuroshio path whose offshore oscillation has high correlation with the CPUE of Ommastrephes bartrami in 152day2interval. In 1999, there were 3 places with the feature, 8 in 2000, 12 in 2001 and 17 in 2002. Monthly, in May 1998, there were 5 places on Kuroshio path whose offshore oscillation has good correlation to the CPUE at 152day2interval, similarly, 3 in June, 11 in July, 6 in August, 1 in September, 7 in October, 10 in November, and 11 in December.
