Contrasted waters of two currents with re- 

 spect to tunas and billfishes. Separated 

 areas at lat. 5°N, which is the approximate 

 border between the North Equatorial Current 

 and Equatorial Countercur rent . Catch rates 

 for bigeye and spearfishes was hardly dif- 

 ferent in the two currents. Yellowfin catch 

 rate in the north area was less than one-half 

 that of the south area. 



KEY WORDS: tuna, bigeye, yellowfin, ocean- 

 ography, currents, catch.

Hypothesized that the fishing grounds of 

 different characters were formed with a close 

 relation to the ocean current systems. Paper 

 related the distribution and migration of 

 tunas and ocean structure and found that tuna 

 distributions could be used as an indicator 

 of seasonal and annual variations of the 

 ocean conditions.

 fin, bluefin, oceanography, currents, temper- 

 ature, season, catch, distribution.

The strength of the Equatorial Countercur rent 

 of the North Pacific and associated varia- 

 tions in sea surface temperatures at its 

 eastern extremity off central America were 

 related to the zonal wind flow in the remote 

 subtropical atmosphere with lags of as much 



as eight months between the wind and tempera- 

 ture . 



KEY WORDS: atmosphere, wind, temperature,
