“…These observations support the idea that fluctuating, irregular flows that are more characteristic of the UMR following large-scale modifications (Lubinski et al 1991;Sparks et al 1998) may have contributed to the decline of the blue sucker through negative impacts on spawning success. Despite probable reduced sampling efficiency due to slightly higher water levels at the time of sampling and dispersal of young via large-scale flooding, abundance of YOY blue sucker was much higher (11·) during 2001 relative to 2002.…”

Ecology of larval blue sucker, Cycleptus elongatus, a North American catostomid that has declined throughout its range, is poorly known because larvae have rarely been sampled. A total of 316 young blue suckers (16.0-39.0 mm total length) was captured over 3 years at 14 offchannel sites in Pool 25, Mississippi River. Blue suckers demonstrated distinct temporal and spatial abundance patterns. Blue suckers were only captured in late May/early June, and were more abundant during a year of little flooding. Abundance was correlated with the distance a site was from the main channel, being highest in island borders and island sloughs in proximity to the channel. Fish guts contained a relatively high biomass of chironomids and zooplankton, suggesting islands were providing suitable feeding opportunities. Because of their proximity to flows, slack waters provided by islands were accessible to blue sucker larvae dispersing from channel spawning areas and facilitated their development into rheophilic juveniles.

“…In overview, fish in the subject area of the Mississippi River experienced hydrologic conditions during the 1993 growing season that were indeed exceptional, particularly in relation to the flow regimes of previous years (see Lubinski et al, 1991;Johnson et al, 1995). Thus, the potential existed for flood effects on growth to have been manifested.…”

Both the Mississippi and Missouri rivers experienced major flooding in the spring and summer of 1993, inundating much of their floodplains for long periods, and allowing fish access to vast but previously inaccessible benthic foraging areas. In response to the latter, we hypothesized that flathead catfish (Pylodictis olivaris) would exhibit altered post-flooding growth as compared to like-aged fish whose lives were flood-free. To test this hypothesis, we obtained the left pectoral fin spines from hoop-netted Mississippi River flathead catfish collected in the vicinity of Crystal City, Missouri, USA, and conducted an individual-based back-calculated growth comparison of individuals captured pre-flood (1991) and post-flood (1996). For like-aged cohorts, our back-calculated length-at-age data clearly show that the post-flooding growth in 1996-collected fish was superior to that of the 1991-collected fish that had experienced less exceptional flow regimes. This outcome suggests that increased forage or/and foraging opportunities can be a consequence of flooding, and that flathead catfish are able to capitalize on this. The natural flooding regime of big rivers may thus be an important contributor to the growth and success of certain fish species; consequently, modifying the river's natural hydrograph and channel morphology may be detrimental.

Altered hydrology resulting from the presence of locks and dams and erosive agricultural land use practices have created conditions that have impacted the growth, distribution, and survival of aquatic vegetation on the Upper Mississippi River System (UMRS). Three inter-related abiotic factors (light transparency, nutrients, and sedimentation) worsened by impoundment and erosive agricultural practices, have played a major role in widespread submersed macrophyte loss in the UMRS. Aquatic vegetation provides food and shelter for biota as well as impacting water quality. Successful efforts to restore aquatic macrophytes on the UMRS have focused on habitat restoration construction projects and water-level management drawdowns. Currently, the status of aquatic vegetation varies within the UMRS, with most of the aquatic vegetation being found between lower Pool 4 (below Lake Pepin) and Pool 13. Although aquatic macrophytes have varied among locations over the past 17 years, an increase in aquatic plants was apparent in 2007 and 2008. Very little research regarding the role of moist soil and emergent vegetation and their responses to ecological factors has occurred within the UMRS. Future research efforts must continue to focus on understanding the ecological and anthropogenic impacts to all aquatic macrophytes within the landscape of one of the largest river systems in the world.
