ABSTRACT 



Commercial catch records of the Hawaii sliipjack fishery for 1952 (a poor year) and 

 11)53 (a good year) are summarized by area and time of catch and by size composition. A 

 unit of fishing effort and its appropriateness are discussed. Geographical distribution of 

 the catch and effort is determined and the two years are compared. Movements of skipjack 

 throughout the fishery are analyzed. The usefulness of the raw catch and the catch per 

 unit of effort as indexes of abundance are considered, and some conjectures as to the nature 

 of the population supporting the fishery are offered.
