The area between Point St. George and Cape 

 San Lucas usually is divided into subareas as 

 follows: 



Northern California 

 Central California 

 Southern California 

 Northern Baja California 

 Upper central Baja California 

 Lower central Baja California 

 Southern Baja California 



Station lines 40- 57 



60- 77 



80- 93 



97-107 



110-120 



123-137 



140-157 



For convenience, I am dropping the prefix 

 and using the term "area" to designate these 

 subdivisions of the CalCOFI area. They are 

 illustrated in figure 1. 



CalCOFI SURVEY CRUISES, 1951-60 



During the decade, 1951-60, CalCOFI sur- 

 veys were nnade at approximately monthly 

 intervals. The majority of both anchovy and 

 sardine larvae were collected during winter 

 and spring; hence coverage on surveys has 

 been most comprehensive during the first half 

 of each year. The frequency of coverage of the 



several areas during 1951-60 is summarized 

 in a two part table (table 1); the upper portion 

 gives the number of coverages per year, and 

 the lower the frequency of coverage by 

 month. 



CalCOFI cruises during these years totaled 

 114; in addition, agencies in CalCOFI partici- 

 pated in the wide-ranging cruise of August 

 1955 called "Norpac." Only 5 months during 

 the decade were without any coverage within 

 the CalCOFI survey area (December 1952, 

 September 1954, November 1954, November 

 I960, and December I960). 



The areas most consistently occupied were 

 the four lying between Point Conception and 

 Point San Juanico (station lines 80- 137). These 

 areas contain the basic survey pattern; they 

 are also the areas from which most sardine 

 and anchovy larvae have been collected. Cov- 

 erage was made off central California (lines 

 60-77) on over half of the cruises, but infre- 

 quently off northern California (lines 40-57), 

 In fact, only 15 cruises extended into the latter 

 area, usually during June and July. The 

 southern Baja California area (lines 140-157) 

 was covered on 29 cruises, most frequently 

 during January through April.
