learned from the results of these studies. However, it is anticipated that 

 there will continue to be gaps in the knowledge of skipjack tuna stock

 the study of the population structure of Pacific skipjack tuna. 



IV. D. Status of SWFC Data Base 



Data from Japanese baitboat operations published in annual 

 statistical digests are included in the data base maintained at the 

 Honolulu Laboratory. Landing statistics from a few of the island states in 

 the western Pacific and data from the Hawaiian pole-and-1 ine fishery, 

 including size data, are also included in the data base.
