Triploid Grass Carp in Lake Marion, South Carolina.
Abstract
The grass carp (Ctenopha,yngodon idella), first introduced to the United States in 1963 as a biocontrol agent for aquatic vegetation, has rapidly expanded its range (Guillory and Gasaway 1978; Clugston and Shireman 1987). More recently, the triploid grass carp has gained popularity because the fish is sterile, has feeding habits similar to diploids, and can be a relatively inexpensive, long-term source of control for nuisance aquatic vegetation (Wattendorf and Anderson 1984; Sutton 1985; Allen and Wattendorf 1987). The use of grass carp to control nuisance aquatic vegetation is not without controversy (Ware and Gasaway 1976;. Gasaway 1978; Fedorenko and Frazer 1978). Often, this fish has been stocked at densities producing no effect on target aquatic vegetation or completely eliminating all aquatic vegetation (Sutton 1977; Leslie et al. 1987; Santha et al. 1991; Kirk 1992). Other concerns include elimination of nontarget aquatic vegetation, migration out of the system, adverse effects on fish communities, and potential movement into or through estuarine nursery areas (Bain 1993).
