The family Catostomidae represents a major component of the fish fauna in the Ohio River. Because of their abundance, large biomass, and susceptibility to environmentally-induced anomalies, suckers are expected to significantly influence the Ohio River Fish Index (ORFIn), a biological index being developed by the Ohio River Valley Water Sanitation Commission (ORSANCO) for large river systems. To correctly interpret information obtained from ORFIn, the impact of suckers upon the index must be thoroughly understood, including relative importance and uneven spatial distribution of Ohio River suckers. In this study, suckers represented 7.1 percent of the total fish captured and 36.6 percent …
