Length-frequency distributions for the dominant taxa of fish larvae in neuston samples and, where comparable, in 

 bongo samples (open histograms), for all cruises combined (1981-86). 



caught in the bongo samples were <15 mm SL. In con- 

 trast, larvae of Bathymaster spp. that were common in 

 the neuston at night did not differ significantly in size 

 from those occurring in the bongo samples; all were 

 small, mostly <10 mm SL. Theragra chalcogramma 

 larvae were also relatively small (all < 15 mm but mostly 

 <10 mm SL) both in bongo and neuston catches. 



Among the remaining neustonic taxa, most larvae 

 caught were >10 mm SL, and length distributions 

 generally displayed one dominant mode within a rela- 

 tively short length interval. The predominant length 

 range for the taxa Hexagrammos decagrammus,
