However, wildlife management boundaries frequently lack biological context and mechanisms to assess demographic data across the...
Ingested toxicity of antimycin A to grass carp Ctenopharyngodon idella and black carp Mylopharyngodon piceus in two carriers
Patrick Kroboth, Duane Chapman, Jeffery A. Steevens, Curtis G. Byrd
2022, Management of Biological Invasions (13) 737-749
Toxic baits are a potential control mechanism for nuisance carps, but rotenone-based baits for grass carp Ctenopharyngodon idella have been ineffective. Failures have been attributed to the palatability of rotenone because innocuous training pellets are readily consumed prior to provision of piscicide baits. Several studies suggest antimycin A, a common...
