Abstract Barriers to fish movement have been used prevent the spread of invasive fishes but may also limit movements native fishes. We evaluated potential consequences a proposed barrier on Illinois River Waterway, meant inhibit silver and bighead carps, continued recovery in Des Plaines following water quality improvements. compared changes upstream cumulative species richness community structure from 1983 2013 DuPage River, an adjacent tributary with impassable dam, area newly where can...
Round goby Neogobius melanostomus – a small, benthic fish native to Eurasia was first introduced North America in the 1980s through ballast water of cargo ships. In 1990, discovered Laurentian Great Lakes Basin and rapidly spread all from 1993 1998. The is an aggressive, prolific, efficient egg predator that subsequently displaced fishes their preferred habitats resources Lakes, where they are well established abundant. From Lake Michigan, moved south into Chicago Area Waterway System slowly...
Abstract Smallmouth buffalo ( Ictiobus bubalus Rafinesque) are a large-bodied fish highly valued and commercially exploited across most of their range. Despite this, relatively little is known population demographics compared to other species. To fill these knowledge gaps, we analyzed two independent long-term datasets (30 57 years, respectively) demographic data (age structure, growth, mortality, age at maturity, recruitment) from multiple pools the Upper Mississippi River System (UMRS)...
Multivariate statistics are commonly used by ecologists to study spatial and temporal community dynamics better inform management decisions. Since these methods a universal tool analyze data, it is important assess their effectiveness using long-term datasets in well-studied systems. The objectives of this were identify trends the fish communities characterize trajectory (i.e., directional or nondirectional) Illinois River, large tributary Mississippi nonmetric multidimensional scaling...
This paper reports the first records of Cercopagis pengoi in Mississippi River Basin, Illinois, USA.In 2017, a total 11 C. were collected from two different locations during zooplankton sampling Illinois Waterway.One location was Chicago Sanitary and Ship Canal second Calumet-Sag Channel, approximately eight 35 river kilometers Lake Michigan, respectively.In 2021, additional individuals encountered ichthyoplankton samples Canal, three upstream 2017 capture location.The extent density within...
Population demographics are used by biologists and managers to determine the quality of a fishery set regulations achieve desired management goals. Regulating large river system that spans substantial geographical region is often complicated spatially variable environmental factors affect fish population dynamics (e.g. habitat, water quality); these rarely examined within an entire system. In this study we compared spatial differences in age length at capture, growth, fecundity body...
Channel catfish (Ictalurus puncatus) and freshwater drum (Aplodinotus grunniens) are two commercially recreationally important species in large rivers of the Midwestern United States. Understanding their population demographics is essential to managing sustainable populations. In this study, we determined compared size structure, individual growth, mortality estimates channel among Illinois River sections Mississippi, Ohio, Wabash provide a current baseline for these Results suggest that...

Water management structures (WMS) are used to regulate water levels between large floodplain river backwaters and their adjacent systems offering a balance maintaining quality backwater habitat providing benefits the systems. The design operation of these WMS is dependent on unique goals, impacts surrounding ecosystem understudied. From 2016–2018 we quantified response fish assemblages (i.e., abundance composition) at Emiquon Preserve, 2723 ha restored lake located main channel Illinois...
Standardized sampling of fishes is either probabilistic (i.e., random) or non-probabilistic fixed), with each having advantages and disadvantages. Our study objective was to evaluate whether a fixed site-survey design for early detection monitoring non-native could be improved by modifying site selection adding random sampling. Results were largely similar but varied evaluation metric; accumulation curves species suggested that performance the survey 10% higher than modified also accumulated...
