“…Since their liberation, bighead (Hypophthalmichthys nobilis) and silver carp (Hypophthalmichthys molitrix) have dispersed northward through the Mississippi River Basin and its tributaries towards the Laurentian Great Lakes of North America (Chick & Pegg, 2001;Naylor et al, 2001). During this period of expansion, bigheaded carp populations have increased substantially and have become one of the predominant fish encountered in many locations (Collins, Butler, Diana, & Wahl, 2015;Collins, Diana, Butler, & Wahl, 2017;MacNamara, Glover, Garvey, Bouska, & Irons, 2016;Sass et al, 2010). Bigheaded carp are filter-feeding planktivores that have been shown to reduce zooplankton and thus pose a substantial ecological threat to many native fishes that rely on zooplankton during larval, juvenile and adult life stages (Chapman & Hoff, 2011;Kolar et al, 2007;Sass et al, 2014).…”

Bigheaded carp (Cyprinidae: Hypophthalmichthys spp.) were brought to North America for aquaculture and eventually escaped captivity. Since their liberation, they have dispersed northward through the Mississippi River Basin and its tributaries. Although bigheaded carp are omnivorous filter‐feeding planktivores, their predatory effects on zooplankton are of principal concern because many native fishes feed on planktonic invertebrates during some phase of their life history. The aim of our study was to quantify the magnitude of effect of bighead carp (Hypophthalmichthys nobilis) on zooplankton body size and daily secondary production across a range of body lengths. We conducted an experiment where we compared responses of zooplankton in the presence of a native fish assemblage (control, n = 5 ponds) and a native fish assemblage plus bighead carp (invaded, n = 5 ponds). The experiment lasted 3 months (June–September, 2014) and was conducted in clay‐lined ponds (0.04 ha. wetted area; 1.5–1.75 m water depths). We quantified the predatory effects of bighead carp on overall changes to the size structure of zooplankton assemblages, body lengths of zooplankton taxa and taxa‐specific changes to standing crop biomass and daily secondary production. The size structure of zooplankton assemblage shifted towards smaller invertebrates in the presence of bighead carp. Bighead carp reduced the individual body sizes of Diaphanosoma (Sididae) (−19%) and Daphnia (Daphniidae) (−9%) after 3 months. Moreover, the standing crop biomass (−92% to 98%) and daily production (−65% to 74%) of Diaphanosoma, Daphnia and Calanoida were reduced in the presence of bighead carp. Bighead carp reduced immature copepod nauplii by 75% when compared to controls and may have affected recruitment to the adult stage. Our experiment indicated that the magnitude of predation by bighead carp increased with zooplankton body size, although rotifers and nauplii were exceptions to this pattern. The combined effects of reduced body sizes of some taxa and direct predation on immature and adult life stages of larger taxa suggest that bighead carp may be affecting zooplankton demographics through additional mechanisms such as reduced egg production, mate limitation, and recruitment.

“…Bighead Carp and Silver Carp may be captured by various gears, including gill nets, hoop nets, fyke nets, pound nets, and electrofishing in backwaters and reservoirs (Collins et al. ; Ridgeway ), but behaviorally these species are filter feeders and tend to be epipelagic, unlike the Black Carp, which is usually considered benthically oriented (Nico et al. ).…”

Black Carp Mylopharyngodon piceus are considered invasive in North America. Since the first wild capture in 2003, collection records have increased, yet information summarizing successful collection methods is lacking. Reported capture methods throughout the Black Carp's native and introduced ranges vary providing minimal aid for determining control and monitoring methods. Here, we describe the current species range and the spatial and temporal variation among captures. The size of fish can affect capture; thus, we report captured fish and gear dimensions and recommend appropriate scientific collection methods. We focus on collection data from 302 Black Carp ranging from 410 to 1,607 mm total length received from 2011 to February 2019. The reported range of Black Carp has expanded in the Cumberland, Illinois, Mississippi, Missouri, Ohio, and Tennessee rivers. Captures most frequently occurred in channel (41%), side‐channel (24%), and backwater (22%) habitat types, with increased records in May, June, and July. Most records were commercial captures, of which hoop net (51%) and gill net (26%) were most common. Results suggest that standard scientific methods for sampling fish in large rivers and standing water by hoop net and gill net may be used to monitor Black Carp, but a robust study design needs to be applied to determine gear selectivity and to determine if catch rates are density dependent or incidental.

Ecological theory has long recognised the importance of positive and negative species interactions as drivers of food web structure, yet many studies have only focused on competition. Because competitive and facilitative mechanisms operate simultaneously, but through different food web pathways, the balance of their combined effects can produce complex and variable responses. We used a response‐surface experimental design to assess the roles of negative (e.g. intra‐, interspecific competition) and positive (e.g. facilitation) interactions between native and invasive juvenile fishes. We tested whether these interactions alter the densities of planktonic and benthic invertebrates to evaluate the magnitude and mechanism(s) influencing the acceptance or resistance of biological invaders. Interactions between bighead carp (Hypophthalmichthys nobilis) and bluegill (Lepomis macrochirus) or common carp (Cyprinus carpio) were evaluated in mesocosms. Intraspecific interactions were 1.5–2.4 times stronger than interspecific interactions between carp species. The only instance of interspecific competition resulted in bighead carp reducing the daily growth of bluegill, whereas the reciprocal interaction resulted in facilitation. Facilitation occurred when bluegill increased the daily growth of low density bighead carp treatments, despite increased numbers of fishes. Bighead carp also increased densities of benthic Chironomidae larvae, which were subsequently consumed by bluegill, but did not result in enhanced bluegill growth. These suites of interactions were not observed between common and bighead carp. Our response‐surface design proved useful for comparing the relative magnitude of intra‐ vs. interspecific competition, identifying facilitation among species, and tracing attendant effects on invertebrate communities. By accounting for the directionality of interactions within our experimental framework and tracking responses of prey at lower trophic levels, we provide a clearer understanding of how competitive effects and stressed consumers alter prey communities and influence facilitation.
