“…Invasive carp reproduction generally occurs in late spring to early summer (Kolar et al 2007). However, collections of mixed size-classes of larvae (Galat et al 2004), gonadal maturation (Schrank and Guy 2002;Papoulias et al 2006), and eggs collected in the Wabash River, Indiana (Coulter et al 2013(Coulter et al , 2016, provide evidence that spawning can be protracted through fall. The persistence of ripe, unspent, and partially spent ovaries in adult females observed as late as October and the back- Although eggs and larvae were collected in the late summer and fall, peak densities generally occurred during late May and June, coinciding with a decline in adult female GSI and an increase in postspawn females.…”

Invasive Bighead Carp Hypophthalmichthys nobilis, Silver Carp H. molitrix, and Grass Carp Ctenopharyngodon idella are expanding throughout the upper Mississippi River (UMR) basin. Spawning has occurred in the main-stem UMR but could be limited to high-discharge events when dam operations create a free-flowing river. Alternatively, naturally free-flowing tributaries could offer alternative habitat for successful reproduction. Our objectives were to examine temporal and spatial variation in adult gonad development, ichthyoplankton densities, and back-calculated spawn dates of invasive carp collected in three UMR tributaries. We compared ichthyoplankton densities between the upstream and mouth reaches of tributaries and densities between the UMR and adjacent tributaries. Ichthyoplankton samples were collected every 10 d, and adult invasive carp were sampled monthly at nine sites throughout the Des Moines, Skunk, Iowa, Cedar, and Mississippi rivers during April-October 2014 and 2015. Peaks in adult gonadosomatic index, an increase in postspawn females, and ichthyoplankton collections suggested that peak spawning occurred during late May through June, when water temperatures were 18-30°C and channel velocities were at least 0.7 m/s. However, reproduction occurred as late as August in some tributaries. Ichthyoplankton densities were highest in the Des Moines River among tributaries, but tributary densities were similar to the UMR densities, suggesting that both tributaries and main-stem sites provide suitable spawning locations. Invasive carp reproduction in UMR tributaries provides additional sources of potential recruitment for further population expansion upstream in the UMR and should be considered when devising plans for controlling populations along the leading edge of the invasion.

“…an individual's growth trajectory) are a likely cause. Bigheaded carps can grow to 100-200 mm in their first growing season depending on the densities of conspecifics (Schrank & Guy, 2002). In contrast, golden shiner only grow to 60-70 mm during the same time (Johannes, McQueen, Stewart, & Post, 1989).…”

Competition during early ontogeny: Effects of native and invasive planktivores on the growth, survival, and habitat use of bluegill

et al. 2019

Early life stages of fishes are sensitive to ecological and environmental disturbances and experience very high mortality rates. During early ontogeny, the growth and survival of larval fish often depends on food availability. Because habitat and diet shifts are strongly tied to individual body size, factors that influence the growth rates of individuals (e.g. resource limitation, competition) also affect other aspects of ontogeny including the timing of habitat or diet shifts. In the context of biological invasions, non‐native species can potentially disrupt the interaction of larval fish with their food via competition for shared prey, reducing growth and survival during a vulnerable period of an organism's life history. We hypothesised that invasive planktivores negatively affect native species through the vulnerable larval life stage via competition for zooplankton resources. To test this hypothesis, we conducted a series of experiments to assess and contrast the effects of invasive (bighead carp, Hypophthalmichthys nobilis) and native (golden shiners, Notemigonus crysoleucas) planktivores on zooplankton densities, and their effects on the growth, survival, abundance, and habitat use of larval bluegill (Lepomis macrochirus). Overall, the effects of the invasive planktivore were consistently greater than the native planktivore in terms of reduced prey densities, reduced bluegill growth rates, and delays to the timing of ontogenetic habitat shifts. Growth rates of bluegill larvae were reduced by 58–87% in the presence of bighead carp and 37% in the presence of golden shiners (relative to controls), but such reductions did not consistently lead to reduced survival (in mesocosm experiment) or relative abundance (in pond experiment). However, we estimated that bighead carp and golden shiners delayed ontogenetic habitat shifts in bluegill by 9–24 and 1–3 days, respectively. Although we did not detect an effect of planktivores on the numbers of larval bluegill, our findings suggest that bighead carp may still affect bluegill ontogeny and freshwater food webs by disrupting the timing of ontogenetic habitat shifts. By affecting the coupling of habitats via organism movements during early ontogeny, bighead carp may indirectly disrupt predator–prey interactions of native taxa.

“…Increases in discharge are often correlated with spawning events, and studies in the Yangtze River also indicated a positive correlation between spawning activity and vorticity (for vorticity values in the order of 0.5 s −1 , Liu et al 2018). However, temperature (between 15 and 30 °C) seems to be a primary driver of spawning behavior for grass carp and bigheaded carps (Schrank and Guy 2002;Coulter et al 2016). Spawning of grass carp is proportional to the size and weight of the female, with an average spawn of 500,000 eggs for a 5 kg female (Shireman and Smith 1983;Chilton and Muoneke 1992).…”

Influence of turbulence and in-stream structures on the transport and survival of grass carp eggs and larvae at various developmental stages

et al. 2019

Understanding the response of grass carp to flow and turbulence regimes during early life stages is fundamental to monitoring and controlling their spread. A comprehensive set of hydrodynamic experiments was conducted with live grass carp eggs and larvae, to better understand their drifting and swimming patterns with 3 different in-stream obstructions: (1) a gravel bump, (2) a single cylinder, and (3) submerged vegetation. The hydrodynamic behavior of eggs and larvae with each obstruction was continuously monitored for about 85 consecutive hours. Transient spatial distributions of the locations of eggs and larvae throughout the water column were generated for each flow scenario. Results show that the active swimming capabilities of larvae allow them to seek areas of low turbulence and low shear stresses, and that eggs are susceptible to damage by high levels of turbulence, which was further corroborated with tests in an oscillating grid-stirred turbulence tank. Our study seeks to better inform field collection of grass carp during early life stages, and to guide the design of alternative approaches to control the dispersal of this invasive species in North America.
