(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 

 65.5% of all fish larvae taken on CalCOFI cruises during 1981 and 

 numbered 10 times as many as the rockfish genus, Sebastes spp. , 

 the next most abundant taxon with 6.4% of the total larvae (Table 

 2, 3). Northern anchovy also ranked first in incidence; Sebastes 

 ranked 2nd. The next most abundant species was the gonostomatid 

 Vinciguerria lucetia with 5.0% of the total, followed by the 

 deepsea smelt Leuroglossus stilbius with 3.5%; they ranked 5th 

 and 4th respectively, in incidence. Pacific hake, Merluccius 

 productus , ranked 5th in abundance (2.5%) and 12th in occurrence. 

 Two myctophids, Stenobrachius leucopsarus and Triphoturus 

 mexicanus , ranked 6th (2.1%) and 7th (1.7%) in number and 6th and 

 8th in occurrence. The final 3 taxa in the top 10 collected in 

 1981 were the Pacific mackerel, Scomber japonicus , with 1.1%, the 

 myctophid Protomytophum crockeri , with 1.0%, and the sanddab 

 genus Citharichthys , also with 1.0% of total larvae. These 3 

 taxa ranked 27th, 2nd, and 9th in incidence, respectively. These 

 10 taxa contributed 89.7% to the total number of larvae collected 

 in 1981; the remaining 10.3% was distributed among 138 taxa plus 

 the disintegrated and unidentified categories. Of the 10 taxa, 3 

 were coastal demersal groups, 2 were coastal pelagic species, and 

 5 were midwater species. 



EXPLANATION OF TABLES 



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

 tow data for 1981 (including November and December, 

 1980) , 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 2-7) . 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: JD, 

 David Starr Jordan; NH, New Horizon.
