Description
Abstract. -- Fish communities of ten streams in the Davy Crockett National Forest were sampled for 12 months in 1994 and 1995. Fish assemblages were identified and subjected to the Index of Biotic Integrity (IBI) and various biological indices to estimate stream quality. The SAS[c] program was used to perform a cluster analysis, Friedman's two-way ANOVA, and Spearman's Rank Correlation to show variances in diversity and fish assemblages between streams. The species list was highly diverse and included some uncommon species. Eight of the ten study streams were similar in quality to Piney Creek, the least impacted stream of the ecoregion. Water quality, anthropogenic influence and impact were inferred for each stream and compared to the results of a concurrent physical/chemical survey. **********
