tion and emigration from the lonfjline grounds are 

 considered in terms of the migratory route of the 

 albacore in the North Pacific Ocean. The data show 

 a clear decline in apparent abundance on the long- 

 line gi-ounds during the 1949-61 study period. This 

 decline could not be related to changes in the aver- 

 age size of the fish or fishing effort. Spatial .statistics 

 were computed to describe the distribution of the 

 albacore on the longline grounds. These show very 

 clear cyclical changes each year. These changes 

 reflect a net southwest movement of the two-dimen- 

 sional first-moment at a velocity of about 6.5 miles 

 (12 km.) day"'. The second order spatial statistics 

 showed a maximum longitudinal expansion and 

 latitudinal contraction during the peak of the fishing 

 season. The time-space coordinates of the two- 

 dimensional first-moment of the albacore distribu- 

 tion appear to be highly predictable. The migration 

 route of the albacore among North American, pole- 

 and-line, and longline fisheries is considered. It 

 appears that the dynamically most significant move- 

 ment of albacore is from the North American fishery, 

 to the pole-and-line fishery, to the longline fishery'.
