Figure 28. The Hawaiian Longline Fishery. The 

 Hawaiian tuna longline or "flagline" fishery is second to the skip- 

 jack. This fishery lands about 4 million pounds of yellowfin and 

 bigeye tuna and marlin each year. The three panels of the above 

 figure show the average monthly landings for the three species for 

 the years 1948 to 1952. Yellowfin are more plentiful during the 

 summer while bigeye are abundant during the winter months. The 

 catch of marlin does not seem to fluctuate much during the year. 

 We do not know whether or not the variations in catch of these 

 deep-swimming fish in the vicinity of the Hawaiian Islands are 

 linked with the variations in the more abundant stock of tuna near 

 the Equator.
