9 1 : 9 ground and marine environmental factors1 Based on daily catch data of Ommastrephes bartrami during 1995 to 2000 by China fishing boats and SST isoline chart covering 1995 to 2000 issued every 3 days by Japan Fisher Information Service Center1 ArcGIS was used to store, manage and analyze the data1 All the catch data were processed and spatialized to display their spatial distribution1 The fishing grounds were identified interactively from the catch data maps1 Matching Ommastrephes bartrami fish2 ing ground with SST isoline map revealed that the relationship between them could be divided into 3 main patterns and 16 subclasses1 The fishing ground in pattern is distributed on the tongue of Kuroshio and Oyashio branches, hence called as tongue type1 Pattern can be further classified into 5 subclasses,i1e1, warm tongue type, cold tongue type, warm tongue + cold tongue type, warm tongue + cold tongue + warm tongue type, and warm tongue + cold tongue + warm tongue + cold tongue type1 Pattern is located on the branch of Kuroshio or Oyashio, so called as branch type1 In pattern, five subclasses can be defined,i1e1, warm branch type, warm branch + cold tongue type, warm branch + cold tongue + warm branch type, cold tongue + warm branch + cold tongue type, and warm tongue + cold branch1 Pattern is distributed on eddy caused by Kuroshio branch encountering Oyashio branch, also named as eddy type1 Pattern can be ulteriorly classified as warm eddy type, warm eddy + cold tongue + warm eddy type, warm eddy + cold tongue ( branch) + warm tongue type, warm eddy + cold tongue type,warm eddy + cold tongue + warm branch + cold tongue + warm branch type,and warm eddy + cold tongue + warm branch type1 Statistical analyses of 239 samples indicate that pattern III has the highest occurrence frequency and highest catch, and pattern II has the lowest occurrence and lowest production1 Subclass 35 has the highest occurrence frequency, and subclass 14 has the highest catch1 The average CPUE of pattern is the highest, pattern the lowest1subclass 31 has the highest CPUE value1 In 1995 and 1996, pat2 terns and dominate1 In 1997, pattern dominates1 From 1998 to 2000, pattern is in domina2 tion1 In August, pattern is in domination1 In September, pattern dominates1 In October, patterns and are in domination1 In November, pattern dominates1 The SST in pattern usually falls between 15 and 21,pattern,17 24, and pattern, The temperature grade in the pattern changes slowly, while pattern, has a big grade change1 Pattern is mainly located on Kurushio branches 3 and 4, pattern on Kurushio branches 2 and 3,and pattern mainly located on Kurushio branches 1 and 21 Key words :Northwest Pacific ; Ommastrephes bartrami ; fishing ground ; spatial pattern
