Hawaiian skipjack peak catch periods each 

 year (1951-61) coincide with summer cold ad- 

 vection periods. The time of initial warming 

 reflects intensified dynamic processes which 

 relate to the displacement of the oceano- 

 graphic climate, which in turn influence the 

 fishery.

Oceanographic conditions were used to predict 

 the relative success of the Hawaiian skipjack 

 fishery.

The author developed a numerical drift model 

 to examine the contribution of currents to 

 the travel (drift) of skipjack from the 

 eastern North Pacific to Hawaii. He found 

 that drift alone is a possible mode of travel 

 in the North Equatorial Current; the time 

 span of 21 to 23 months fits tagging data. 



KEY WORDS: tuna, skipjack, larvae, currents, 

 convergence/discontinuities.
