SPECIES SUMMARY 



Larvae of northern anchovy {Engraulis mordax) represented 

 60% of all fish larvae taken on CalCOFI cruises during 1962 and 

 numbered eight times as many as the gonostomatid Vinciguerria 

 lucetia , the next most abundant species with 7% of the total 

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

 incidence; V. lucetia ranked third. The next most abundant 

 species was Pacific hake, Merluccius productus , with 6% of total 

 larvae; it ranked 7th in occurrence. The myctophid Triphoturus 

 mexicanus ranked 4th in abundance (4%) and 2nd in occurrence. A 

 deepsea smelt, Leuroglossus stilbius , ranked 5th in abundance 

 (4%) and 8th in incidence. Larvae of Sebastes spp. , a composite 

 of about 70 species, ranked 6th in abundance and 5th in 

 incidence. Larvae of jack mackerel {Trachurus symmetricus) , 

 sanddabs (Citharichthys spp.), the myctophid Stenobrachius 

 leucopsarus , and the gonostomatid Cyclothone spp. completed the 

 10 most abundant taxa ranking 7th, 8th, 9th, and 10th, 

 respectively; in incidence, these taxa ranked 11th, 10th, 13th, 

 and 4th, respectively. These 10 top-ranking taxa contributed 

 90.5% of all larvae taken during 1962. The remaining 9.5% was 

 represented by 129 taxa plus the unidentified and disintegrated 

 categories. Of the 10 taxa, 5 were midwater species, 3 were 

 coastal demersal species or generic groupings, and 2 were coastal 

 pelagic species. 



EXPLANATION OF TABLES 



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

 tow data for 1962, 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 

 indicates the line and decimal fraction and the second 

 set indicates the station on the line. 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: AX, 

 Alexander Agassi z ; BD, Black Douglas; HO, Horizon; PT, 

 Paolina T.

 taxa taken during 1962 in ranked order.
