Avoidance behavior of cold-, cool-, and warmwater fish exposed to Zequanox in a two-choice preference chamber
Zebra ( Dreissenia polymorpha , Pallas 1771) and quagga ( D. bugensis , Andrusov 1897) mussels, collectively referred to as dreissenid mussels, are invasive bivalves native to the Ponto-Caspian region of Eurasia (Stepien et al. 2013; Benson 2018a). High fecundity and a free-swimming planktonic life stage allow for easy and rapid dispersal of dreissenid mussels (Mackie 1991; Marsden et al. 2013)...
Assessment of Open Water Zequanox Applications for Controlling Dreissenid Mussels within an Inland Lake
Invasion of dreissenid mussels (zebra and quagga mussels, Dreissena polymorpha and D. rostriformis bugensis , respectively) into the Great Lakes and Mississippi River Basins has resulted in estimated economic impacts as high as $1 billion annually for maintenance and repair of biofouled water conveyance systems and other infrastructures (Pimentel et al. 2005).
Invasive Mussel Control Science: Management Tools for Assessing the Risks and Control of Invasive Dreissenid Species
Invasive zebra and quagga mussels ( Dreissena polymorpha and D. rostriformis bugensis , respectively) are causing significant ecological and economic impacts and the scope of these impacts increases as they continue to spread across North America. The USGS conducts science to inform management actions for controlling and mitigating the impacts of invasive mussels. Studies include evaluation and...
Use of electrified fields to control dreissenid mussels
Zebra and quagga mussels were first introduced into the Great Lakes in the 1980’s and they have since expanded to over 750 inland lakes in addition to the 5 Great Lakes. A 2009 study conducted by the Idaho Aquatic Nuisance Species Taskforce estimated the annual economic threat of dreissenids to Idaho to be $94 million. A literature review conducted by Lovell and Stone (2005) demonstrates the...
Exposure-Related Effects of Zequanox on Lake Sturgeon (Acipenser fulvescens) and lake trout (Salvelinus namaycush) Survival and Condition
A dead-cell, spray-dried powder formulation of Pseudomonas fluorescens, strain CL145A was recently approved by the US Environmental Protection Agency (EPA) for control of dreissenid mussels (zebra mussel, Dreissena polymorpha and quagga mussel, Dreissena rostriformis bugensis) in open-water environments. The EPA approved product, Zequanox® (registration number 84059-15) is manufactured by Marrone...
Temperature-dependent toxicity of molluscicides to zebra mussels
Zebra mussels (Dreissenia polymorpha) are native to the Black, Caspian, and Aral Seas of eastern Europe (Gollasch and Leppäkoski 1999) and they were likely introduced into Lake Erie as veliger larvae in the summer or fall of 1985 (Hebert et al. 1989). Their high reproductive capacity and planktonic larval stage enable zebra mussels to rapidly disperse (Birnbaum 2011). Less than 10 years after...
