Shingu, C. 1970. Studies relevant to distribution and 

 migration of southern bluefin. Bull. Far Seas 

 Fish. Res. Lab. 3:57-114. 



A history of the fishery, seasonal distribu- 

 tion and migration paths, and distribution by 

 age class, with comments on stock and sub- 

 group distribution. He described the fishes' 

 distribution by month and area, and noted the 

 spawning and migration grounds and catch 

 relations to temperature-salinity diagrams 

 for the different areas and ages of fish. 



KEY WORDS: tuna, southern bluefin, catch, 

 season, distribution, migration, spawning, 

 temperature, salinity, age, environment.

 a lalunga ) fishing off California in relation to 

 sea surface temperature isotherms as measured by 

 an airborne infrared radiometer. Unpubl . manuscr.

Described the association discovered between 

 albacore fishing and certain sea surface 

 temperatures and temperature discontinuities. 



KEY WORDS: tuna, albacore, catch, oceanog- 

 raphy, temperature, color, transparency,

 of the southeastern tropical Atlantic Ocean. U.S.

Authors infer that, given adequate informa- 

 tion, wind data as a factor influencing the 

 ocean surface layer can be used to predict 

 the distribution of tuna schools. Wind 

 speeds also directly impact fishing opera- 

 tions and can be used to generally outline 

 potential areas and times of the year for 

 fishing . 



KEY WORDS: tuna, meteorology, winds, season, 

 distribution .
