SPECIES SUMMARY 



Larvae of northern anchovy 

 50.9% of all fish larvae taken on 

 numbered five times as 

 lucetia , the next most 

 larvae (Tables 2, 3). 

 respectively, in numbers 



{Engraulis mordax) represented 

 CalCOFI cruises during 1961 and 

 the gonostomatid Vinciguerria 

 species with 10.3% of the total 

 species ranked 1st and 3rd, 



many as 



abundant 

 These 



of occurrences. The third most abundant 

 species, the myctophid Triphoturus mexicanus , constituted 5.7% of 

 all larvae and ranked 2nd in occurrence. Larvae of Sebastes 

 spp. , a composite of about 70 species, ranked 4th in abundance 

 (4.8%) and occurrence. The deepsea smelt Leuroglossus stilbius 

 ranked 5th in abundance and 7th in occurrence. Larvae of Pacific 

 hake (Merluccius productus) ranked 6th in abundance but only 14th 

 in occurrence. The lanternfish Stenobrachius leucopsarus ranked 

 7th in abundance and 10th in occurrence. The sanddab genus 

 Citharichthys spp. ranked 8th in abundance and occurrence. Jack 

 mackerel (Trachurus symmetricus) and the lanternfish 

 Ceratoscopelus townsendi ranked 9th and 10th in abundance and 

 19th and 16th in occurrence. The 10 top-ranking taxa contributed 

 86.9% of all larvae taken during 1961. The remaining 13.1% was 

 represented by 139 taxa and the unidentified and disintegrated 

 categories. Of the 10 top-ranking 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 1961, 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 2-6) . 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: BD, 

 Black Douglas; HS, Hugh M. Smith; HO, Horizon. 



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

 taxa taken during 1961 in ranked order.
