Figure 5. Ranked bigheaded carp (Hypophthalmichthys spp.) catches among river strata based on (a) catch rates, (b) precision (relative standard error), and (c) catch rates + precision. Errors bars are 1 standard error for the averaged ranking for each gear type. Habitat strata are abbreviated according to Wilcox 1993. BW = Backwater, IMP = Impounded, MCB = Main channel border, SC = Secondary channel, TRI = tributary TW = Tailwater.

Figure 1. Conceptual representation of the gear performance matrices used to evaluate gear catch rates or gear precision in differing river strata. (Step 1) Each cell (representing gear by strata) was assigned a score (see methods). Averages (± SE) across river strata and gear types (see dashed arrows) were used to compare gear performance. (Step 2) Scores from each matrix were summed to create a third matrix representing the combined Catch rates and Precision attributes.

Evaluating the efficacy of using GPS satellite transmitters to assess movement of bigheaded carp in a riverine system

<p>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 understanding habitat use and daily surfacing trends in movement would strengthen management efforts.</p> <p>Custom Fastloc™-GPS data-logging transmitters (with radio telemetry capability) manufactured by Sirtrack™ were tethered to adult bigheaded carp in field experiments. </p> <p>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.</p> <p>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 of 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. </p>

Data from: Hydrology controls recruitment of two invasive cyprinids: bigheaded carp reproduction in a navigable large river

In the Mississippi River Basin of North America, invasive bigheaded carp (silver carp Hypophthalmichthys molitrix and bighead carp H. nobilis, also referred to as Asian carp) have spread rapidly over the past several decades. In the Illinois River, an important tributary of the Upper Mississippi River, reproduction appears to be sporadic and frequently unsuccessful, yet bigheaded carp densities in this river are among the highest recorded on the continent. Understanding the causative factors behind erratic recruitment in this commercially-harvested invasive species is important for both limiting their spread and managing their harvest. We analyzed weekly catch records from 15 years of a standardized monitoring program to document the emergence of age-0 bigheaded carp in relation to environmental conditions. The appearance of age-0 fish was generally linked to hydrographic attributes, which probably serve as a cue for spawning. However, we found profound differences in the number of age-0 fish among years, which varied by as much as five orders of magnitude in successive years. The strong link between summer flooding and age-0 fish production we observed emphasizes the importance of understanding the hydrologic context in which sustained invasions occur. Despite evidence of sporadic recruitment, bigheaded carp populations in the Illinois River appear to be consistent or increasing because of particularly strong, episodic year classes.
