120mx23m study site seined from lower to upper end and all fish collected identified to species and counted. In instances where a taxon was extremely abundant a numerical estimate was derived through extrapolation from subsamples some speciments were retained for purposes of identification. Most fish were returned to the stream alive. There is little reason to suspect collecting affected assemblage structure except for a few species of darters early in the study. The subsequent recovery of these species indicated that this had minimal effect on our results. site seined from lower to upper end and all fish collected identified to species and counted Unit of abundance = IndCountInt, Unit of biomass = NACitation(s)
