“…Silver carp ( Hypophthalmichthys molitrix ) and bighead carp ( Hypophthalmichthys nobilis ), collectively known as bigheaded carps, are cyprinid fishes that were introduced into the United States in the early 1970s, discovered in the wild in the early 1980s, and become established and abundant in the Mississippi River Basin (MRB) ever since (Kolar et al., 2007). The bigheaded carps outcompete some indigenous species such as gizzard shad Dorosoma cepedianum and bigmouth buffalo Ictiobus cyprinellus , attributed mainly to their trophic specialization, high mobility, rapid growth, high fecundity, and planktivorous diet (Chick & Pegg, 2001; Irons, Sass, McClelland, & Stafford, 2007; Xie & Chen, 2001), and may impact native biodiversity and local fisheries (Chick & Pegg, 2001; Irons et al., 2007; Sampson, Chick, & Pegg, 2009; Xie & Chen, 2001). …”
