Alverson, D.L. 1961. Ocean temperatures and their re- 

 lationship to albacore tuna ( Thunnus germo ) dis- 

 tribution in waters off the coast of the states of 

 Oregon, Washington, and the province of British 

 Columbia. J. Fish. Res. Board Can. 18:1145-1152. 



Discussed American coastal fishery for alba- 

 core tuna in relation to temperature fea- 

 tures. Fish concentrations occur along the 

 interface of warm oceanic waters and cooler 

 waters adjacent to the coast. Highest catch 

 rates were recorded in water temperatures 

 between 58° and 61°F. The author felt the 

 fish were above the thermocline, in warm 

 oceanic-type water. 



KEY WORDS: tuna, albacore, temperature,

Average quarterly distribution of purse seine 

 and baitboat catches. Annual fluctuations in 

 catch by quarter and area. Indications of 

 fish movement from catch distribution. Men- 

 tioned unusual oceanographic conditions in 

 the region during 1953 which may have been 

 responsible for the large catches in 1954. 

 Postulated that both yellowfin and skipjack 

 movements into and out of the waters off Baja 

 California were related to the temperature 

 regime of that area.

 graphy, distribution, catch, migration,
