Sebastes spp. larvae (no./lOOO m3) in MESSHAI tows. Average of (A) deep and (B) shallow tows 

 at inshore (solid) and offshore (shaded) stations; (C) densities in 0-200 m stratum (average of 

 pooled 40-m strata) from sequential deep tows at inshore station; (D) densities in 0-40 m stra- 

 tum (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-hatchmg) and after 

 storm (hatching). 



low MESSHAI tows, the frequency of positive tows in- 

 creased, along with larval densities (Fig. 20, C and D). 

 The distribution of larvae became somewhat shallower 

 in shallow MESSHAI tows after the storm (Fig. 20F). 



Discussion 



Northern anchovy larvae dominated samples from 

 both study sites. The midwater species Leuroglossus 



stilbius and Stenobrachius leiicopsarus and the rock- 

 fish genus Sebastes were relatively abundant at the 

 two sites. These three taxa, along with Merluccius 

 productus (ranked 10th in abundance) and Bathy- 

 lagus ochotensis (ranked 13th), constitute a distinct 

 larval recurrent group in the California Current re- 

 gion ( Moser and Smith, 1993 ). These three taxa were 

 also closely linked in other analyses of larval fish 

 assemblages in the study region (Gruber et al., 1982; 

 McGowen, 1993). Sebastes spp. and Merluccius
