“…Moreover, bigheaded carp (i.e. collectively silver carp and bighead carp H. nobilis) planktivory has been associated with the decline in abundance and condition of formerly dominant native planktivores in the Illinois River, such as gizzard shad Dorosoma cepedianum and bigmouth buffalo Ictiobus cyprinellus (Irons et al 2007;Pendleton et al 2017;Fritts et al 2018), and is coincident with a change in the overall fish community of the La Grange Pool of the lower river (Solomon et al 2016). Additionally, Emiquon has received low bluegill fishing pressure (15% of anglers 2015 and 31% of anglers 2016) compared to other sportfish such as largemouth bass Micropterus salmoides and crappie species Pomoxis spp., which could be impacting their growth and development (Low 2015;Hoff and Jugovic 2016).…”

Population demographics are used by biologists and managers to determine the quality of a fishery and set regulations to achieve desired management goals. Regulating a large river system fishery that spans a substantial geographical region is often complicated by spatially variable environmental factors that affect fish population dynamics (e.g. habitat, water quality); these dynamics are rarely examined within an entire system. In this study we compared spatial differences in population age and length at capture, growth, fecundity and body condition of bluegill Lepomis macrochirus among two different river reaches (e.g. basin width, gradient, velocity) of the Illinois River (Illinois, USA) and a disconnected floodplain lake, the Emiquon Preserve. Variations in selected population demographics were evaluated in relation to well-documented habitat characteristics (e.g. water quality, aquatic vegetation, backwater availability). Differences in bluegill demographic traits between the disconnected floodplain lake and river reaches were distinct, and variations between river reaches were sex specific. The floodplain lake generally had older bluegill that expressed a higher maximum length at age and a lower growth rate and fecundity than bluegill in river reaches. River bluegill differed between river reaches in male growth, and fecundity in both sexes. Body condition was not significantly different among bluegill populations. Early research on floodplain lakes indicates that this habitat supports greater fish growth and higher reproductive fitness than mainstem habitat. We conclude that increasing the availability of quality backwater habitat, even within a highly modified large river system like the Illinois River, could substantially increase the quality and stability of bluegill populations.

“…A variety of undesirable changes have occurred in areas with high densities of these species. For example, the high efficiency with which bigheaded carp remove phytoplankton and zooplankton can create strong changes in the base of aquatic food webs (DeBoer et al, 2018; Fritts et al, 2018; Sass et al, 2014) and lead to competition with native species (Irons et al, 2007; Pendleton et al, 2017; Sampson et al, 2009), both of which may contribute to shifts in fish assemblages (Chick et al, 2020; Solomon et al, 2016). Resource managers have undertaken efforts to limit further range expansion to mitigate the negative consequences of bigheaded carp invasions in new areas.…”

Fish movements in regulated rivers can be challenging to study because anthropogenic modifications, such as locks and dams, can influence animal behavior. Upper Mississippi River Lock and Dam 19 (LD 19), for example, is an invasive carp movement bottleneck due to an impassable dam. Upstream fish passage at LD19 is restricted to the lock chamber, making it an optimal location to test invasive fish deterrents that could limit further range expansion. Evaluating the effectiveness of experimental deterrents requires baseline knowledge of fish movements and suitable sample sizes of fish encountering the deterrents to ensure adequate statistical power. Some evidence indicates fish with prior upstream experience may return upstream or challenge potential deterrents at a higher rate than fish without such experience. To test how previous upstream experience could increase the rate at which fish moved upstream through a navigation lock chamber, we compared upstream passage through LD 19 using bigheaded carp captured below the dam (downstream‐origin) and two groups of bigheaded carp captured upstream from the dam: those that swam downstream on their own volition (upstream‐origin fish) and those that were captured upstream and translocated downstream of LD 19 (translocated upstream‐origin). Translocated upstream‐origin carp demonstrated the highest rate of upstream passage, with 59% of the fish detected downstream from LD 19 passing upstream during our study. In contrast, downstream‐origin carp made no upstream passages over 2 years. Fish origin was shown to influence upstream passage success. This may be an important consideration for fish passage studies and deterrent evaluations.

“…In locations where Bighead Carp have invaded, they cause large‐scale ecological and economic damage (Hansen, 2010), especially when they reach high abundances, such as in parts of the Illinois River (e.g., Silver Carp [ H. nobilis ] and Bighead Carp combined up to 80% fish biomass; Coulter, MacNamara, et al, 2018). For example, native planktivores are negatively impacted by invasive Bighead Carps (Fritts et al, 2018; Tristano et al, 2019) and plankton assemblages are altered (e.g., Collins & Wahl, 2018). The Illinois Waterway has been a focal point for Bighead Carp management because this waterway connects the Mississippi River Basin to the valuable fisheries resources of the Laurentian Great Lakes via man‐made canal systems.…”
