encompassed the vertical distribution of sardine eggs and larvae. 

 Wide-ranging joint biological and oceanographic survey cruises 

 were resumed in 1949 with sardine as the focus; however, an 

 increasing interest in other biological components resulted in 

 the deepening of standard tows to 140 m in 1951. This marked the 

 beginning of truly guantitative ichthyoplankton sampling on 

 CalCOFI surveys. 



Data resulting from CalCOFI surveys in 1967 have been 

 published in a number of forms. Hydrographic data (Univ. of 

 Calif., SIO, 1969) were presented in a standard format. 

 Distributional maps of larvae of two taxa taken on CalCOFI 

 surveys during 1967 are presented in the CalCOFI Atlas series: 

 rockfish (Sebastes spp.), Ahlstrom et al., 1978; northern anchovy 

 (Engraulis mordax) , Hewitt, 1980. 



A computer data base for eggs and larvae of sardine and 

 anchovy, for larvae of hake (Merluccius productus) , jack mackerel 

 {Trachurus symmetricus) and Pacific mackerel {Scomber japonicus) , 

 and for eggs of Pacific saury (Cololabis saira) was established 

 in 1969. The development of a data base for other fish larvae is 

 a complex undertaking because competency of identification has 

 evolved steadily over the past 38 years. We began the task of 

 producing a CalCOFI ichthyoplankton data base and associated data 

 report series in 1983. All available original records for 1967 

 were subjected to an extensive verification and editing process 

 to produce this report. This and previous (Ambrose et al., 

 1987a, b,c; 1988; Sandknop et al., 1987a, b; 1988a, b; Stevens et 

 al., 1987a, b,c; 1988; Sumida et al., 1987a, b; 1988a, b) and 

 subseguent reports make the CalCOFI ichthyoplankton and station 

 data available to all investigators and serve as guides to the 

 computer data base. The data base will be modified when 

 additional errors are discovered and when composite taxa from the 

 earlier years are reidentif ied. These reports are the 

 fundamental reference documents against which subseguent changes 

 in the data base can be compared. 



SAMPLING AREA AND PATTERN 



In 1967, CalCOFI survey cruises were conducted only in June- 

 July (Cruise 6706) and December (Cruise 6712) . Cruise 6706 is 

 designated as 6707 in the hydrographic data reports (Univ. of 

 Calif., SIO, 1969). A total of 258 stations included in this 

 data base was occupied on these 2 cruises (170 stations on 6706 

 and 88 stations on 6712) . Coverage of the survey station pattern 

 varied between cruises and the entire survey area was not covered 

 on any single cruise (Figures 1-3, Table 1). The area off 

 northern California (lines 40-57) and central California (lines 

 60-77) was not covered. The area between Pt. Conception, 

 California and Pt. Abreojos, Baja California (lines 80-130) was 

 surveyed in June-July on Cruise 6706. The area from Cape San 

 Quintin to Pt. San Juanico, Baja California (lines 107-137) was 

 surveyed in December on Cruise 6712. Coverage extended seaward 

 to station 140 (approximately 450 miles offshore) on lines 90 and
