indicating relatively large sample sizes. The next most abundant 

 species, Vinciguerria lucetia , a midwater gonostomatid, was 

 widespread in samples from the southern part of the CalCOFI 

 pattern and ranked 4th in occurrence. Jack mackerel larvae 

 ranked 4th in abundance and 8th in occurrence. Larvae of 

 Sebastes spp. , a composite of about 70 species, ranked 5th in 

 abundance and 1st in occurrence. The next most abundant were 

 three midwater species, a deepsea smelt (Leuroglossus stilbius) 

 and two lanternf ishes (Stenobrachius leucopsarus and Triphoturus 

 mexicanus) , ranking 6th, 7th, and 8th, respectively. The latter 

 ranked 2nd in occurrence. Sardine larvae ranked 9th in 

 abundance but only 21st in occurrence, indicating large sample 

 sizes. The 10th ranked taxon was the sanddab genus 

 Citharichthys , a composite of about 6 species whose distributions 

 in aggregate cover most of the CalCOFI pattern. These 10 top- 

 ranking taxa contributed 84.2% of all larvae taken during 1951. 

 The remaining 15.8% is represented by 124 taxa. 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 the pertinent station and tow data for 

 1951, 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 2-13). Stations 

 are designated by two groups of digits; the first set 

 indicates the line and decimal fraction, if necessary, 

 and the second set indicates the station on the line. 

 Decimal fractions were not used in 1951. Time is 

 listed as Pacific Standard Time at the start of each 

 tow in 24-hour designation. Methods for determining 

 tow depth, volume of water strained, standard haul 

 factor, and percent sorted were described in the 

 methods section. The values for total fish eggs and 

 larvae represent raw counts (unadjusted for percent 

 sorted or standard haul factor) . Ship codes are as 

 follows: BD, Black Douglas; CR, Crest; HO, Horizon; 

 PT, Paolina T; YE, Yellowfin; 47, N. B. Scofield . 



Table 2 - This table lists pooled occurrences of all larval fish 

 taxa taken during 1951 in ranked order. 



Table 3 - This table lists pooled counts of all larval fish taxa 

 taken during 1951 in ranked order. Numbers are 

 adjusted for percent sorted and standard haul factors.
