Anchovy larvae (no./lOO m3) in MESSHAI tows. Average from (A) deep tows and (B) shallow tows 

 at inshore (solid) and offshore (shaded) stations; (C) densities in 0-40 m stratum from sequential 

 deep tows at inshore station; (Dl densities in 0-40 m stratum (average of pooled 10-m strata) 

 from sequential shallow tows at inshore station; average from (E) deep and (F) shallow tows at 

 inshore station before storm (cross-hatching) and after storm (hatching). 



MESSHAI tows in the upper 200 m showed a trend 

 of increasing density just before the storm and a 

 sharp decrease in poststorm tows (Fig. 14C). In shal- 

 low MESSHAI tows, densities peaked in two tows taken 

 one day before the storm but were not appreciably dif- 

 ferent in pre- and poststorm samples (Fig. 14D). 



Sebastes spp. larvae Rockfish larvae were concen- 

 trated in the upper 80 m of the water column, with 

 low average densities between 80 and 200 m (Fig. 

 15A). In deep MESSHAI tows the highest average 



density was in the 40-80 m stratum at the offshore 

 station but in the 0-40 m stratum at the inshore sta- 

 tion (Fig. 15A). In shallow MESSHAI tows at the 

 inshore station, average density was highest in the 

 20-30 m stratum, relatively low in the 0-10 m and 

 10-20 m strata, and nearly as high at the surface as 

 in the 20-30 m stratum. Offshore, shallow MESSHAI 

 tows showed extremely low average densities in the 

 upper 30 m of the water column; larvae were not 

 taken in surface net tows. At the inshore station, 

 average larval densities were higher in samples
