“…Mean water temperature and discharge as well as derived variables quantifying changes in these metrics were evaluated for their influence on the movement of different bigheaded carp groups. Temperature and discharge have previously been linked to broad‐scale movements of bigheaded carp, spawning behaviours and timing, and habitat use (Coulter et al, , ; DeGrandchamp et al, ). However, bighead carp and silver carp, and especially their hybrids, probably respond differently to each of these variables (Coulter et al, ).…”

“…Two movement metrics were calculated to evaluate differences in the movements among bigheaded carp groups and determine the effects of year, season, sex, total length, and environment on movement likelihood (detected on same stationary receivers [stationary] or at different location [moving]), distance, and direction. Net and total movement distances were calculated for each pair of consecutive detections for each individual where total distance is the distance travelled regardless of direction and net movement combined distance and direction such that negative values indicated downstream movements and positive values indicated upstream movements (Coulter et al, ). Not all study years and months had detections from all bigheaded carp groups.…”

“…Behavioural differences among bigheaded carp hybrids and parental species could affect the establishment of these species in different habitats as well as their dispersal and range expansion. Movements and behaviours of bigheaded carps have commonly been related to water temperature, river discharge, and changes in temperature and discharge (Coulter, Bailey, Keller, & Goforth, , ; Coulter, Schultz, Tristano, Brey, & Garvey, ; DeGrandchamp, Garvey, & Colombo, ; Lubejko et al, ) with silver carp movements sometimes more strongly linked with river discharge whereas bighead carp movements were more strongly linked with water temperature (Coulter et al, ). Unfortunately, these studies only visually identified bighead carp and silver carp, so groupings were likely to contain a mixture of parental species and hybrid individuals that may have confounded results.…”

“…Unfortunately, these studies only visually identified bighead carp and silver carp, so groupings were likely to contain a mixture of parental species and hybrid individuals that may have confounded results. Additionally, bigheaded carps engage in broad‐scale movements, especially during spawning, which may function to expand the range of these species (Coulter, Bailey, Keller, & Goforth, ; DeGrandchamp et al, ). However, bighead carp and silver carp cue to different environmental conditions for spawning (Krykhtin & Gorbach, ; Opuszyński & Shireman, ; Zhou, Liang, & Huang, ) and movement (Coulter et al, ), and individuals within the population may be more or less mobile than other individuals (Prechtel, Coulter, Etchison, Jackson, & Goforth, ).…”

Introgressive hybridisation between two invasive species has the potential to contribute to their invasion success and provide genetic resiliency to rapidly adapt to new environments. Additionally, differences in the behaviour of hybrids may lead to deleterious ecosystem effects that compound any negative impacts of the invading parental species. Invasive silver carp (Hypophthalmichthys molitrix) and bighead carp (Hypophthalmichthys nobilis) provide an opportunity to evaluate how hybridisation may influence the behaviour, dispersal, and spread of an invasive species introgressive complex. In order to investigate the role hybrids may have in the invasion ecology of bigheaded carps, we examined the distribution, movements, and environmental cues for movement of two invasive fishes and their hybrids in the Illinois River (U.S.A.). Early generation hybrids (e.g. F1,F2, and first‐generation backcross individuals) composed a greater proportion of the population at the invasion front where abundances of bigheaded carp were low. A greater proportion of early hybrids passed through dams upstream towards the invasion front than did other hybrids and parental species. The movements and environmental cues for movement of late‐generation backcrosses (more genetically similar to parental genotype) were not different from the parental species with which they shared the most alleles. Although the direction of the relationship between movement and environment was sometimes different for the parental species and associated advanced generation hybrids, these results indicate that management for parental species will also affect most hybrids. Although early generation hybrids are rare, our results indicate they may disperse towards low‐density population zones (i.e. invasion fronts) or are produced at greater frequency in low‐density areas. These rare hybrids have the potential to produce a variety of unique genetic combinations that could result in more rapid adaptation of a non‐native population to their invaded range potentially facilitating the establishment of invasive species.

Factors Regulating Year‐Class Strength of Silver Carp Throughout the Mississippi River Basin

Recruitment of many fish populations is inherently highly variable interannually. However, this variability can be synchronous at broad geographic scales due to fish dispersal and climatic conditions. Herein, we investigated recruitment synchrony of Silver Carp Hypophthalmichthys molitrix across the Mississippi River basin. Year‐class strength (YCS) and synchrony of nine populations (maximum linear distance = 806.4 km) were indexed using catch‐curve residuals correlated between sites and related to local and regional climatic conditions. Overall, Silver Carp YCS was not synchronous among populations, suggesting that local environmental factors are more important determinants of YCS than large‐scale environmental factors. Variation in Silver Carp YCS was influenced by river base flow and discharge variability at each site, indicating that extended periods of static local discharge benefit YCS. Furthermore, river discharge and air temperature were correlated and synchronized among sites, but only similarities in river discharge were correlated with Silver Carp population synchrony, indicating that similarities in discharge (i.e., major flood) among sites can positively synchronize Silver Carp YCS. The positive correlation between Silver Carp YCS and river discharge synchrony suggests that regional flood regimes are an important force determining the degree of population synchrony among Mississippi River Silver Carp populations.

We have evaluated the feasibility of using GPS satellite transmitters on invasive bigheaded carp species, silver carp and bighead carp, that could determine patterns of movement, identify potential feeding and spawning areas, and inform a comprehensive monitoring and commercial removal program in the Illinois River Waterway system in the United States. Despite a wealth of information on bigheaded carp movement from acoustic and radio telemetry, a finer‐scale approach to understand habitat use and daily surfacing trends in movement would strengthen management efforts. Custom Fastloc™‐GPS data‐logging transmitters (with radio telemetry capability) manufactured by Sirtrack™ were tethered to adult bigheaded carp in field experiments. Sixteen field‐deployed transmitters were recovered and yielded 490 individual GPS waypoints when transmitters were attached to fish. We observed movement rates within the Dresden Island Reach of the Illinois River Waterway of approximately 16 river km, and movement in and out of backwater habitats and the warm‐water discharge of a nuclear generating station. We have demonstrated the use of this technology to monitor bigheaded carp and will use the information gained from this study to inform future work with remotely accessed, real‐time, Argos satellite linked prototypes. Fine‐scale accuracies, fast acquisition speeds and the ability to gather real‐time data make this a promising tool and is one the first uses of GPS technology to track fish movement in a riverine system. Continued exploration to improve tag retention efficiency will enhance its utility for continued invasive carp management.
