REPORTS VOLUME XI, 1 JULY 1963 TO 30 JUNE 1966127been sampled as consistently as the others off Baja<strong>California</strong>.The distribution of anchovy larvae was somewhatdifferent than that of sardines (Figure 7). Anchovylarvae were important in the area off central <strong>California</strong>(lines 60-77) only during 1958 and 1959, andin the southernmost area (lines 140-157) only during1956 ; they were taken in only a few hauls off northern<strong>California</strong> (lines 40-57). In the remaining areas, theywere more consistently represented throughout the10-year period than sardine larvae. Anchovy larvae,like sardine larvae, were more abundant off <strong>California</strong>during the warm years, 1957-59. In these years,the center of anchovy abundance shifted from centralBaja <strong>California</strong> to southern <strong>California</strong>.I wish now to deal more specifically with occurrencesand eo-occurrences of larvae and eggs of thetwo species. Information concerning occurrences andeo-occurrences of the two species in the seven areasare summarized in Tables 3 and 4. For completeness,I have included information on occurrences and cooccurrencesof both species for 1961-63, as well as for1951-60. The total number of stations occupied on<strong>CalCOFI</strong> cruises during each year, 1951-63, are summarizedby area in Table 5. These summations arenot limited to regular <strong>CalCOFI</strong> stations, but includeextra occupancies and special cruises (Table 6). However,the analysis that follows is based on the datafor 1951-60.Throughout the <strong>CalCOFI</strong> survey period, anchovylarvae always have occurred in more collections thansardine larvae (Figure 8). In the 1950's as a whole,anchovy larvae occurred in 3.1 times as many haulsas sardine larvae. The disparity was lowest in 1952TABLE 5SUMMARY OF STATIONS OCCUPIED ON CalCOFl SURVEY CRUISES, BY YEAR AND AREA, 1951-63(Station lines given below each area)YearNorthern<strong>California</strong>40-57Central<strong>California</strong>60-77Southern<strong>California</strong>80-93NorthernBaja Calif.97-107Upper centralBaja Calif.<strong>11</strong>0-120Lower Baja central Calif.123-137SouthernBaja Calif.140-157TotalMonthly cruises1951 ......................1952 .1953---.-.---.------.-.-..1954 .1955 ......................1956 ......................1957 ......................1958 .1959 .1960------...-_-_-__-.-...45290137540412262243164<strong>11</strong>910995<strong>11</strong>210123023216533735047841840339536445957243925828724927430228028735241934 126335231935235330836039147342020127726727 1212182267274345286691413367976<strong>11</strong>4in5<strong>11</strong>9<strong>11</strong>31,4361,4731,4451,4731,45<strong>11</strong>,4071,4931,8522.1821,826Total. ..................273 1,5704,2153,0493,5912,58275816,038128858123724326618318520620921021819<strong>11</strong>82226515129539201,009TABLE 6STATIONS OCCUPIED ON REGULAR CalCOFl CRUISES AND SPECIAL CRUISES, INCLUDING EXTRA OCCUPANCIES, 1951-64LateMarch cruiseExtraoccupancies ofregular stationsSpecial towsAdditionalinshore stationsMultipleoccupancies(not included)Total0636300000000 l o343602680000000000000000001,4361,4731,4451,4731,45<strong>11</strong>,4071,4931,8522,1821 1: 1,826Total .___________________I 15,789 126108150(224)16,0389449198818770000913700000012531900009539201,0091,2031 Includes 54 stations occupied on Norpac.
