identified myctophids," "unidentified mycto- 

 phids," and "disintegrated myctophids." A sum- 

 mary of this appendix table is contained in Table 



19. 



Appendix Table 5.— Counts of selected cate- 

 gories of fish larvae, tabulated by station, for all 

 stations occupied on ETP II. Table contains 

 23 categories including 11 species, 5 genera, and 

 7 families. Of these, 12 were included in the 

 category "other identified larvae" in Appendix 

 Table 1, the remainder provide information on 

 counts of larvae at the generic or specific level 

 for several families listed in Appendix Table 1. 



Appendix Table .4.— Summary of occurrences 

 and numbers of larvae of 23 categories, limited 

 in distribution to a broad coastal band or around 

 offshore islands or banks. Only positive stations 

 are included. These 23 categories were included 

 under "other identified larvae" in Appendix 

 Table 1. 



Appendix Table 5. — Numbers and kinds of eel 

 leptocephali (Anguilliformes) obtained on the 

 second multivessel EASTROPAC cruise (ETP 

 II), tabulated by family for all positive hauls. 

 A summary of this table is given in Table 20. 



Appendix Table 6. — Numbers and kinds of 

 lophiiform larvae obtained on the second multi- 

 vessel EASTROPAC cruise (ETP II) tabulated 

 by family for all positive hauls. A summary 

 of this table is given in Table 23. 



Appendix Table 7. — 7A contains counts of 

 fish larvae, tabulated by family or larger group- 

 ing, for all stations occupied by Oceanographer 

 on zig-transect; 7B contains station counts of 

 myctophid larvae for same cruise, tabulated by 

 genus or species; and 7C contains station counts 

 of selected categories of fish larvae on same 

 cruise. 



Appendix Table 8. — Station data and stan- 

 dardized haul factors for second multivessel 

 EASTROPAC cruise and for Oceanographer zig- 

 transect. Included for each station are locality, 

 date and time of collection, depth of haul, and 

 standardized haul factor. The standardized 

 haul factors are used to adjust original counts 

 of larvae to the comparable standard of numbers 

 of larvae in 10 m^ of water strained per meter 

 of depth fished. It should be noted that the mid- 

 time of haul for each station is recorded as Pa- 



cific Standard Time. However, the symbols D 

 (Daylight), N (Night), DT (Day Twilight), 

 NT (Night Twilight) accurately reflect the local 

 condition at each station. Twilight hauls were 

 taken within 1 hr of local sunrise or sunset. 



2. CLUPEIDAE 

 (9 occurrences, 270 larvae) 



As on ETP I, three species of Clupeidae lar- 

 vae were obtained. Larvae of the sardine, 

 Sardinops sagax (Jenyns), (7 occurrences, 179 

 larvae) and round herring, Etrumeus acumina- 

 tus Gilbert, (3 occurrences, 7 larvae) were taken 

 in the vicinity of the Galapagos Islands while 

 larvae of the thread herring, Opisthonema sp., 

 (2 occurrences, 84 larvae) were taken at two 

 coastal stations oflF southern Mexico, with sur- 

 face water temperatures of 28.7° and 29.3°C. 

 Six of the occurrences of sardine larvae were at 

 contiguous stations, along long 92 °W, between 

 lat 1°N and 3°S, just seaward of the Galapagos 

 Islands (Figure 3). Surface water tempera- 

 tures at these stations ranged betv/een 16.4° and 

 19.3°C. We sampled the Galapagos sardine pop- 

 ulation on ETP II, at a period of rather high 

 reproductive activity. 



3. ENGRAULIDAE 

 (35 occurrences, 1,360 larvae) 



The Peruvian anchovy, Engraulis ringens 

 Jenyns, (25 occurrences, 1,307 larvae) also was 

 sampled on ETP II during a period of high re- 

 productive activity (Figure 3). Einarsson and 

 Rojas de Mendiola (1967) determined that the 

 spawning season of the Peruvian anchovy ex- 

 tended from August to March, hence the early 

 part of the 1967-68 spawning season was sam- 

 pled on ETP II and the close of the previous 

 spawning season on ETP I. Surface temper- 

 atures at positive stations ranged between 15.4° 

 and 18.8°C. Larvae of other engraulids (10 

 occurrences, 53 larvae) were taken at nearshore 

 stations over a wide area between lat 20 °N and 

 the equator.
