Abstract
Flow regime, energy source, water quality, and habitat structure within stream systems play major roles in controlling the structure of resident fish communities (Gorman and Karr, 1978; Karr and Dudley, 1981; Schlosser, 1982). Based on the hypothesis that there are predictable relationships between stream variables and fish community structure, overall stream condition has been assessed using indices such as the Index of Biotic Integrity (IBI) (Karr, 1981; Karr et al., 1986). The IBI integrates a wide range of information pertaining to fish community structure that reflects the prevailing chemical, physical, and biological condition of the stream. Assessments made using the IBI have been correlated to actual stream conditions and appear to be sensitive to a wide range of environmental degradation (Fausch et al., 1990).
