Diel changes in the vertical distribution of all larvae (excluding walleye pollock), and Hippoglossoides 

 elassodon, Bathymaster spp., Ammodytes hexapterus, Gadus macrocephalus, and Pleuronectes bilineatus 

 larvae. Bars are mean abundances per 1000 m 3 at each depth interval and error bars are ± one standard 

 deviation about the mean abundance.
