<em>Abstract</em>.—Using Long Term Resource Monitoring Program data collected from impounded (Pool 26) and unimpounded (Open River) reaches of the upper Mississippi River, we investigated population dynamics of flathead catfish <em>Pylodictis olivaris</em>, channel catfish <em>Ictalurus punctatus</em>, and blue catfish <em>I. furcatus</em> from random sites located in side channel border (SCB) and main channel border (MCB) habitats. Objectives were to (1) compare trends (1993–2007) of three catfishes collected in Pool 26 and Open River reaches of the upper Mississippi River, and (2) provide needed information to managers on population dynamics through time using a binary gear approach of active (i.e., daytime electrofishing) and passive gears (hoopnetting). Active gears resulted in a higher catch per unit effort (CPUE) of all catfishes in each habitat–reach combination as compared to passive gears. Passive gears resulted in negligible catches of blue catfish and flathead catfishes (e.g., mean of <1 fish/net night). Catch per unit effort using active gear resulted in a greater number of channel catfish captured in Pool 26 compared to the Open River, with Open River SCB habitat having the lowest CPUE in most years. Blue catfish in the Open River had a higher CPUE using active gear as compared to Pool 26, with the Open River MCB having the greatest CPUE. Flathead catfish had a higher CPUE in MCB habitat compared to SCB habitat, with the Open River MCB having the highest CPUE in most years. However, declining trends in flathead catfish appears to be occurring in Open River habitats while trends in flathead catfish appear to be slightly increasing in Pool 26. The most common length-classes captured were substock and stock-sized fish regardless of habitat, species, or reach. Trends for channel catfish were easily determined due to high catch rates; however, more monitoring and enhanced sampling is needed to accurately assess flathead catfish and blue catfish trends and to accurately determine demographics for all three species.

Upper Mississippi River System

Abstract Empirical assessments of the influence of invasive species on native species are infrequent because the required long-term data are rarely available. The invasion of silver carp in the Upper Mississippi River System (UMRS) provides a unique opportunity to assess the influence of this invasive species on native fishes because a highly standardized, long-term monitoring program has been sampling the fish communities in six reaches of the UMRS for over 20 years. We analyzed fish abundance (catch per unit effort from electrofishing) and water-quality data collected from 1994 to 2013 from three reaches where silver carp populations have been established since 2000, and three reaches where they are not established. Our results provide empirical evidence of a negative effect of invasive silver carp on native sport fish in the UMRS. Although water temperature, suspended solid concentration, and flooding also differed substantially between control and invaded reaches, only silver carp abundance had a direct negative relationship with the abundance of adult sport fish. Our analyses suggest that the mechanism for this decline may be competition for zooplankton between silver carp and larval/juvenile sport fish. In reaches where silver carp is established, recruitment of juvenile sport fish appears to be constrained relative to reaches where silver carp is not established.

<em>Abstract</em>.—Muskellunge <em>Esox masquinongy </em>management programs often rely on stocking to create and maintain populations. In many instances, a native and nearby stocking source is unavailable or a genetically suitable brood source is unclear. Genetic differences among stocks of Muskellunge may influence survival and growth when introduced into novel environments. Consequently, the selection of a suitable brood source can be difficult and possibly critical to the success of Muskellunge stocking programs. We examined differences in long-term survival and growth among introduced Muskellunge stocks from the Ohio and upper Mississippi River drainages and a mixed-origin Illinois broodstock population in three Illinois reservoirs. Catch per unit effort (CPUE) from spring modified-fyke netting suggested that the upper Mississippi River drainage stock at ages 3 and 4 persisted at lower relative abundance compared to conspecifics; however, low lake- and stock-specific catches of older ages precluded robust CPUE comparisons among stocks. Apparent survival, estimated from mark–recapture data with the Cormack-Jolly–Seber open population model, differed among stocks 1-year poststocking, with the upper Mississippi River drainage stock exhibiting markedly lower survival compared to conspecifics. Annual variation in survival to age 1.5 was related to water temperature at stocking, fish size at stocking, first winter temperatures, and first summer temperatures. However, survival did not differ among stocks for Muskellunge age 2 and older, indicating that important factors structuring long-term survival exert their effects most strongly in the first year poststocking. Despite overall low survival of Muskellunge from the upper Mississippi River drainage, males that survived exhibited a slight growth advantage compared to conspecifics. No growth advantage was observed for upper Mississippi River drainage stock females. Our findings suggest that stock selection in addition to environmental conditions can influence survival of introduced Muskellunge and subsequent contribution to the fishery.

Long Term Survey

This paper reports the results of a long-term survey of the invertebrates living in caves and other subterranean habitats in the Upper Mississippi River Valley, particularly in the region frequently but erroneously called the Driftless Area. Sixteen troglobitic species are known: two flatworms, two amphipods, one isopod, four spiders, one mite, and six collembolans. The terrestrial troglobite fauna probably represents cave invasion and isolation following Early Pleistocene glaciation, and demonstrates that the caves were habitable while the region was at the margin of Late Pleistocene glaciations. The groundwater troglobite fauna may have survived in situ while the region was covered by glacial ice in the Early Pleistocene. The troglophile fauna consists of at least 78 species, and these species may or may not have come into the region since the Wisconsinan glaciation recession. The presence of troglophile species in a particular cave is highly sporadic.

Upper Mississippi River System

We present information gleaned from 10 years of data collected by the water quality component of the Upper Mississippi River Restoration Environmental Management Program’s Long Term Resource Monitoring Program (LTRMP) from Pool 26 of the Upper Mississippi River System (UMRS). The Pool 26 reach of the UMRS includes the confluence with the Illinois River, and the confluence with the Missouri River just downstream of Mel Price Locks and Dam. The surrounding communities in both Illinois and Missouri benefit greatly from the natural resources provided by these rivers. We estimate that annual expenditures are 55 million for fishing and hunting, respectively, in the region surrounding Pool 26 based on license sales and state expenditure data from the U.S. Fish and Wildlife Service. Additionally, there is a commercial fishery active in Pool 26, recreational boating, and the UMRS provides drinking water for many municipalities in this region. Finally, the Upper Mississippi River System is a major transportation system, and Pool 26 receives the greatest amount of barge traffic for any river reach in the UMRS. The LTRMP began collecting data in 1988, but the first years of the program were experimental. Currently followed monitoring protocols for water quality and fish monitoring were adopted in 1993; however, a major flood event in that year prevented full data collection for that year. Data from the LTRMP water quality component demonstrate that Pool 26 is a highly productive river reach. Long-term averages of chorophyll-a, total phosphorous, total nitrogen, and total inorganic solids are comparable to levels in eutrophic to highly eutrophic lakes. The average current velocity in the main channel of the Mississippi River in Pool 26 ranges from 0.364–0.414 m/sec. during the summer and fall. Even during the lowest discharge levels in a year, the reach has a residence time no longer than 2.7 days. Discharge was significantly related to many water quality parameters, including Secchi depth, turbidity, total suspended solids, total nitrogen, nitrate-nitrite, and total phosphorus. We observed a significant linear increase in mean water temperature in the main channel from 1994 to 2004. When these data were analyzed by season, positive linear trends were found during the spring (0.515°C per year) and fall (0.646°C per year). Continued monitoring is necessary to determine if these observations represent short term fluctuations or long-term trends and to detect any related effects on this river reach.
