Carp, Fish Management, Rorenone
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 bait within minutes. Only three dead common carp were observed in 1994 and no dead carp were observed in 1995. The common carp would not consume enough rotenone pellets for a fatal dosage. Their selectiveness is attributed to their ability to detect the rotenone in the pellets. More palatable rotenone baits are needed for common carp.
