the CalCOFI survey area in 1951-56 was given 

 by Ahlstrom (1956). The tennperature range 

 over which anchovy eggs were takenin 1953 and 

 1954 was 9.9°to23.3°C; mostweretakenwithin 

 a 7°C. range, 12.0-18.9°C. (Ahlstrom, 1956). 

 The southern extent of anchovy spawning 

 and its offshore extent in the area between 

 San Francisco, Calif., and Magdalena Bay, 

 Baja California, have been adequately cir- 

 cumscribed by CalCOFI survey cruises. The 

 northern extent of anchovy spawning has not 



been adequately delimited, however. For ex- 

 ample, we do not know how consistently anchovy 

 spawning occurs off Oregon and Washington, or 

 how large the adult stocks are in these waters. 

 Information from our surveys permits the 

 assessment of the relative abundance of anchovy 

 larvae off California and Baja California 

 (table 4). The nnajority of anchovy larvae have 

 occurred off Baja California in most years; 

 the exceptions are 1957, 1959, and 1964 

 (table 5 and fig. 5).
