two species. In Figure 12, we have utilized the data 

 presented by Kume and Joseph (1969a, 1969b) as 

 well as data from Royce (1957), Mais and Jow 

 (1960), Shomura 2 , and Anonymous (1970c), to plot 

 the distribution of sailfish and shortbill spearfish by 



5-degree areas. The sailfish comprise nearly 100% 

 of the catch of the two species shoreward of a line 

 drawn from the intersection of lat. 10°N and long. 

 115°W to the intersection of lat. 5°S and the coast of 

 Peru. As one moves seaward of that diagonal the
