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.

The Long Term Resource Monitoring Program (LTRMP) completed 2,653 collections of fishes from stratified random and permanently fixed sampling locations in six study reaches of the Upper Mississippi River System during 1991. Collection methods included day and night electrofishing, hoop netting, fyke netting (two net sizes), gill netting, seining, and trawling in select aquatic area classes. The six LTRMP study reaches are Pools 4 (excluding lake Pepin), 8, 13, and 26 of the Upper Mississippi River, an uninpounded reach of tue Mississippi River near Cape Girardeau, Missouri and the La Grange Pool of the Illinois River. A total of 61-79 fish species were detected in each study reach.

The Long Term Resource Monitoring Program (LTRMP) completed 2,797 collections of fishes from stratified random and permanently fixed sampling locations in six study reaches of the Upper Mississippi River System during 1997. Collection methods included day and night electrofishing, hoop netting, fyke netting (two net sizes), gill netting, seining, and trawling in select aquatic area classes. The six LTRMP study reaches are Pools 4 (excluding lake Pepin), 8, 13, and 26 of the Upper Mississippi River, an unimpounded reach of the Mississippi River near Cape Girardeau, Missouri, and the La Grange Pool of the illinois River. A total of 66-76 fish species were detected in each study reach. For each of the six LTRMP study reaches, this report contains summaries of: (1) sampling efforts for each combination of gear type and aquatic area class, (2) total catches of each species from each gear type, (3) mean catch-per-unit of effort statistics and standard errors for common species from each combination of aquatic area class and selected gear type, and (4) length distributions of common species from selected gear types.

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.
