The species composition, relative abundance, and distribution of fishes in Navigation Pool 8 of the Upper Mississippi River was described. Evaluations were based on data collected from 38 areas sampled during the summer of 1975. A total of 23,716 identifiable specimens, representing 70 species and 18 families, was collected during this survey. Of these, 65 species were classified as natural resident species, and one as an introduced resident species. Of the four non-resident species collected, three appeared to be transient individuals from small tributary streams and one a bait bucket introduction.
