Plankton volumes (miyiOOO m'') in MESSHAI tows. Average volumes from (A) deep tows and (B) 

 shallow tows at inshore (solid I and offshore (shaded) stations; (C) volumes in 0-200 m stratum 

 (average of pooled 40-m strata) from sequential deep tows at inshore station; (Dl volumes in 0- 

 40 m stratum (average of pooled 10-m strata) from sequential shallow tows at inshore station; 

 average from (E) deep tows and (F) shallow tows at inshore station before storm (cross-hatching) 

 and after storm (hatching). 



inshore station than at the offshore station (Fig. IIA; 

 ANOVA of shallow strata, F^ 95=31.78, P=0.003). 

 Within the upper 50 m at the inshore station, aver- 

 age density was highest in the 10-20 m stratum, 

 accounting for approximately AO^c of larvae. Density 

 in the surface layer was comparatively low. In deep 

 strata no significant difference in larval density was 

 found between inshore and offshore stations 

 (^1 ]7=0.53, P=0.47). At the inshore station, average 

 larval densities were lower in poststorm samples 



than in prestorm samples (shallow strata: J'^j 54= 

 11.21, P=0.001; deep strata: Fj jo=10.05, P=0.06l). 

 Overall, larval distribution was somewhat shallower 

 after the storm (Fig. 11, E and F). 



Leuroglossus stilbius larvae In deep MESSHAI 

 tows, larvae of L. stilbius occurred in relatively high 

 densities in most strata down to 200 m (Fig. 12A). 

 The lower limit of their distribution was not deter- 

 mined by the MESSHAI samples, but another study
