This exceptional station was located in an area where oceanographic studies indicate 

 upwelling may occur, which would enrich the water and provide more food for the skipjack. A 

 more intensive study in this area will be made. 



The seasonal peak in April of the number of schools sighted per day did not correspond 

 with the summer peak in the catch of the fishery. This was due to a predominance in April of 

 schools of smaller fish, which the fleet took in markedly less quantity than the fewer larger fish 

 found in the summer months. 



Forty-three percent of the fish schools which were approached and chummed with live 

 bait came close enough to the vessel for some fish to take the hook.
