No current technology can specifically target Grass Carp Ctenopharyngodon idella for control within aquatic ecosystems. Other than TFM (3-trifluoromethyl-4-nitrophenol) for Sea Lamprey Petromyzon marinus control, available control chemicals used in aquatic invasive species management programs are non‐selective and typically applied throughout the entire water column, resulting in equal exposure of native and invasive species alike.
Developing delivery systems that target unique feeding strategies of specific organisms could increase the ability of management agencies to control or limit a species like Grass Carp, and minimizing potential impacts on native fishes. Considerations such as food preference, spatial distribution, digestive physiology, and feeding attraction/stimulation can be brought together and incorporated with chemical control agents into a single species-specific control tool. The goal of this project is to evaluate the lethality of a bait designed for Grass Carp incorporated with a Antimycin-A, a previously registered control chemical for fish.
