Abstract
Polar ordination of fish capture data from Nine Mile Creek, Onondaga County, New York, indicated the presence of localized midsummer assemblages of fishes that corresponded to pool, riffle, and intermediate transition habitats (pool head, pool tail, run). The white sucker was characteristic of pools; longnose and blacknose dace predominated in riffles. The cutlips minnow, creek chub, northern hog sucker, and tessellated darter used transition habitats extensively. Species diversity was high in the pool, pool head, and run, and low in the riffle and pool tail; differences among habitats were due to variation in both species richness and species evenness.
