Hester, F.J. 1961. A method of predicting tuna catch 

 by using coastal sea-surface temperatures. Calif. 

 Fish Game 47:313-326. 



Described the seasonal and areal variation in 

 albacore and bluefin catch in southern Cali- 

 fornia and Baja waters. Developed a correla- 

 tion between sea surface temperature at two 

 southern California shore stations and blue- 

 fin and albacore catch from selected areas. 

 It was possible to forecast tuna catch using 

 winter water temperatures prior to the fish- 

 ing season. 



KEY WORDS: tunas, albacore, bluefin, catch, 

 distribution, temperature, season, food, 

 enrichment, environment. 



Howa 



Discussed evidence for a cause-effect rela- 

 tionship between temperature and tuna distri- 

 butions. States that ". . . most researchers 

 agree that surface temperature does not 

 directly influence the distribution and 

 availability in tropical waters except near 

 the upper and lower limits of tolerence." 

 Noted also that temperature values for a 

 given species varied with geography. 



KEY WORDS: tuna, albacore, yellowfin, blue- 

 fin, bigeye, skipjack, currents, distribu- 

 tion, environment, oceanography, temperature, 

 food, enrichment, upwelling, fronts, water
