Tests Of A Rotenone-Impregnated Bait For Controlling Common Carp, Joseph L. Bonneau, Dennis L. Scarnecchia
Journal of the Iowa Academy of Science: JIAS
An experimental rotenone-impregnated pelleted (approximately 10 mg/pellet) bait was tested in force-feeding and field-feeding experiments as a method of control for common carp (Cyprinus carpio). Mortality rates of force-fed fish ranged from less than 40% when fed one pellet to 100% when fed more than 10 pellets. Mortality occurred within 48 h. Mortality rates of control fish did not exceed 10%. In reservoir feeding trials in 1994 and 1995, carp were fed for 2-3 weeks on a non-toxic, vegetable-based bait dispensed by automatic feeders, followed by one feeding of the bait with rotenone added. Carp ceased feeding on the rotenone …
