alternative markets for the few large yellowfin as well as the inci- 

 dental catch of a few bigeye tuna and spearfishes . The only serious 

 defect of this method of fishing is the large amount of hand labor 

 involved in setting enough of this gear to make a commercially 

 profitable catch in the American economy. Preliminary experi- 

 ments warrant confidence that a faw simple modifications in the 

 design of this gear will adapt it Lo mechanized hauling without 

 seriously impairing the catching rate. This should overcome the 

 only serious deterrent to the development of a large central Pacific 

 fishery for tuna.
