Based on the catch data of Chinese large lamp purse seines in the East China Sea from 1998 to 2003,the tempo-spatial distributions of the mackerel resource and fishing grounds in the East China Sea were analyzed using the methods of correlation analysis and grey relationship analysis.

Based on the catch data from Chinese fishing vessels and surface temperature data between June and November from 1995 to 2001, the catch distribution and the relationship between fishing ground and surface temperature for Ommastrephes bartrami in three fishing areas in the Northwestern Pacific are analyzed using GIS software and statistics methods.

The annual positions of fishing ground for Ommastrephe bartrami from 150°E to 165°E in the North Pacific from 1995 to 2001 are compared based on spatial distance aggregative and gray incidence methods.
