Abstract only. Related tuna fishing results 

 to cold- and warm-water variations. Postu- 

 lated an inverse relation between skipjack 

 catch on the Japanese side and that on the 

 American side of the Pacific. Catches varied 

 as did temperature on the two sides of the 

 ocean. Bluefin catches were noted to decline 

 with cold-water intrusions and to increase 

 wi th warming .

 ture, currents, upwelling, fronts, enrich- 

 ment, meteorology, migration, catch.

Described the range of temperature for a num- 

 ber of organisms and summarized the ecologi- 

 cal principles which seem to influence or 

 regulate localizations and processes which 

 act to influence suitable or nonsuitable con- 

 ditions for fishing.
