examining archived specimens. A listing of each taxon by station 

 (Table 4) was produced, which became the primary document for 

 subsequent checks. Misidentif ications found in geographic 

 outlier checks and other misidentif ications and data problems 

 discovered in the course of examining archived samples resulted 

 in several iterations of Table 4. Finally, totals in Table 4 

 were checked against annual summaries of incidence and abundance 

 (Tables 2 and 3) . Ecological analyses of the data were conducted 

 concurrently with editing procedures and provided cross-checks 

 that allowed correction of errors. 



SPECIES SUMMARY 



Larvae of northern anchovy {Engraulis mordax) represented 

 60% of all fish larvae taken on CalCOFI cruises during 1963 and 

 numbered over six times as many as the gonostomatid Vinciguerria 

 lucetia , the next most abundant species with 8.8% of the total 

 larvae (Table 2, 3). Northern anchovy also ranked first in 

 incidence; V. lucetia ranked 3rd. Next most abundant was 

 Sebastes spp., a composite of about 70 species, with 6.1% of 

 total larvae; it ranked 3rd in occurrence. Pacific hake, 

 Merluccius productus , ranked 4th in abundance (3.3%) and 10th in 

 incidence. The myctophid Triphoturus mexicanus ranked 5th in 

 abundance, but ranked 2nd in occurrence. A deepsea smelt, 

 Leuroglossus stilbius , ranked 6th in abundance and 9th in 

 incidence. Jack mackerel, Trachurus symmetricus , ranked 7th in 

 abundance but only 12th in occurrence. Citharichthys , a 

 composite of about five species whose distributions in aggregate 

 cover most of the CalCOFI pattern, ranked in the top ten in both 

 abundance (8th) and occurrence (5th) . Pacific sardine, Sardinops 

 sagax , and the lanternfish Stenobrachius leucopsarus completed 

 the 10 most abundant taxa ranking 9th and 10th respectively; 

 however, neither of these taxa ranked in the top 10 in occurrence 

 (22nd and 14th respectively) suggesting relatively large sample 

 sizes. These 10 top-ranking taxa contributed 87.9% of all larvae 

 taken during 1963. The remaining 12.1% was represented by 141 

 taxa plus the unidentified and disintegrated categories. Of the 

 10 taxa, 4 were midwater species, 3 were coastal demersal species 

 or generic groupings, and 3 were coastal pelagic species. 



EXPLANATION OF TABLES 



Table 1 - This table lists by cruise the pertinent station and 

 tow data for 1963, the volume of water filtered and 

 standard haul factor for each tow, the percent of 

 sample sorted, and the total numbers of fish eggs and 

 larvae. CalCOFI cruises are designated by four digits; 

 the first two indicate the year and the second two the 

 month. Within each cruise the data are listed in order 

 of increasing line and station number (southerly and 

 seaward directions) ; the order of station occupancy is 

 shown on the station charts (Figures 2-5) . Stations 

 are designated by two groups of digits; the first set
