LOEB: VERTICAL DISTRIBUTION OF LARVAL FISHES 



Gonostomatid and myctophid larvae made up 

 most of the ichthyoplankton in the upper 100 m 



(Figure 2). The "other larvae" were a low, constant 

 percent of the total from the surface to 75 m, but 



their percent contribution was markedly in- 

 creased between 75 and 350 m. Below 350 m most 

 of the larvae were sternoptychids and gono- 

 stomatids. 



Family Gonostomatidae 



The gonostomatids (8 genera, 12 species) com- 

 posed 48% of the identified larvae. The family was 

 an important fraction of the total larvae in all 

 strata (Figure 3a); 97% of the estimated family 

 abundance occurred above 100 m. Maximum 

 abundance was at 25-50 m due to concentrations of 

 the two most abundant species Cyclothone alba 



interval; and frequency of occurrence (F) in (n) samples, percent of tx)tal estimated water column abundance, median length, and size 

 range (mm standard length) within each depth interval.
