TOTAL LENCTH (mm) 



Figure 9.-Length-frequency (histograms) and biomass (line graphs) distributions, of Euphausia 

 pacifica, 1953-54 cruises. Dotted bwxes appended to histograms for body lengths 16-21 mm are 

 corrections for net avoidance using Isaacs' (1965) factors derived for anchovy larvae of those sizes. 

 Corrections are not applied to biomass. Arrows trace development of cohorts. Solid arrows trace 

 sequences considered clear, dashed arrows trace those less clear.
