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.

A total of 163 species of fish have been collected and identified from the Upper Mississippi River since record keeping began late in the 19th century. Records of occurrence appearing in this document have been obtained from a variety of sources, including personal notations by field biologists, agency reports, published reports in the scientific literature on the distribution of fishes in various regions, and more recent habitat and community fish sampling initiated by the Long Term Resource Monitoring Program (LTRMP). This document is meant to provide a consolidated listing of species that presently occur, have occurred, or have been collected in the Upper Mississippi River. Rankings were assigned concerning distribution and relative abundance of those species throughout the river.

Since the original publication of George C. Becker's landmark Fishes of Wisconsin in 1983, many changes have occurred in the Wisconsin fish fauna. Currently, 147 native species are recognized, one more than in Becker (1983). Two additional native species, southern brook lamprey (Ichthyomyzon gagei) and channel shiner (Notropis wickliffi), have been found in the state, and one former native species, longjaw cisco (Coregonus alpenae), is now considered merely a distinctive form of shortjaw cisco (Coregonus zenithicus). Hybrid northern redbelly X finescale dace (Phoxinus eos X Phoxinus neogaeus) may represent an additional unisexual clonal species, but genetic analyses of Wisconsin populations are required for confirmation. Six native species - ghost shiner (Notropis buchanani), ironcolor shiner (Notropis chalybaeus), creek chubsucker (Erimyzon oblongus), deepwater cisco (Coregonus johannae), blackfin cisco (Coregonus nigripinnis), and shortnose cisco (Coregonus reighardi) - are extirpated from the state. Two species thought by Becker (1983) to be extirpated, skipjack herring (Alosa chrysochloris) and black redhorse (Moxostoma duquesnei), have been rediscovered but are rare. Three endangered species, striped shiner (Luxilus (formerly Notropis) chrysocephalus), pallid shiner (Notropis amnis), and slender madtom (Noturus exilis), have declined greatly in distribution and abundance and are now nearly extirpated. Fourteen non-native species are currently established in the state, with kokanee salmon (Onchorhynchus nerka), threespine stickleback (Gasterosteus aculeatus), white perch (Morone americana), ruffe (Gymnocephalus cernuus), and round goby (Neogobius melanostomus) newly reported since Becker's (1983) book. At least 19 additional non-native species have been reported from state waters but are not currently established; 2 of these, red shiner (Cyprinella (formerly Notropis) lutrensis) and pink salmon (Oncorhynchus gorbuscha) had been tentatively considered by Becker (1983) to be established. The scientific names of 16 native and 2 non-native Wisconsin fishes have been changed, and several others may be changed in the future.

Personnel of the Long Term Resource Monitoring Program for the Upper Mississippi River System have collected fish information in Navigation Pool 8 since 1989. In this report, I summarize data collected during the period 1991-97, in which gear deployment methods and sampling periods remained stable but fixed-site sampling changed to predominantly stratified random sampling in 1993. Sampling collections totaled 3,596 and yielded 324,948 fish of 91 species. Sampling effort increased over time, mainly when the change to random sampling occurred. Annual catches and species totals increased when random sampling was implemented; catches increased even with stable sampling effort in recent years. Of 12 gear types used, day and night electrofishing, seining, and mini-tyke netting were used the most often, produced the greatest catch totals, and also yielded the highest species totals each year. Bluegill (Lepomis macrochirus), spotfin shiner (Cyprinella spiloptera), and emerald shiner (Notropis atherinoides) were the most abundant species and also occurred in the greatest percentage of collections, indicating widespread abundance. Sixteen species yielded more than 5,000 individuals each. Family Cyprinidae was represented by 21 species and 141,497 fish, Centrarchidae by 9 species and 71,375 fish, and Catostomidac by 14 species and 26,776 fish. Twenty-one of 91 total species were rarely caught. Skipjack herring (Alosa chrysochloris), previously described as extirpated, was documented in the 1993 flood year. American brook lamprey (Lampetra appendix) and rainbow smelt (Osmerus mordax) were recorded for the first time in the Upper Mississippi River in 1993. Fantail darter (Etheostoma flabellare) and banded darter (Etheostoma zonale) were documented for the first time in Pool 8 in 1997. Population trends for 15 species of perceived interest to river managers and the public indicated mainly stable a populations.
