 but have risen rapidly since then (Fig- 

 ure 33). 



The following description is 

 based on the 1 956-1 968 catches (Fig- 

 ure 32): 



In the first quarter of the year, 

 the highest catch rates occurred 

 around the easternmost part of Bra- 

 zil, and the greater Antilles 



In the second quarter, the area of 

 relatively high catch rates off Brazil 

 extended farther to the northwest, and 

 catch rates were high in the northern 

 Gulf of Mexico, and off the Bahamas 

 and the eastern United States north- 

 ward to latitude 40°N and eastward 

 to longitude 65°W. The concentra- 

 tions off easternmost Brazil and off
