USGS scientist making microparticles for use in the field.

Field Evaluation of Microparticles

With this study, we will validate the use of microparticles to selectively deliver a control agent to feral bigheaded carps. Prior controlled studies conducted in ponds at the Columbia Environmental Research Center (CERC) in Columbia, Missouri indicated that microparticles could be used to deliver antimycin to bigheaded carps while not impacting non-target species like Largemouth Bass and Grass...

Data release for a novel tool to selectively deliver a control agent to filter-feeding silver and bighead carp Data release for a novel tool to selectively deliver a control agent to filter-feeding silver and bighead carp

Invasive carp pose substantial economic and ecological damage when populations are widespread in freshwater systems within the United States of America (USA). Resource managers in the USA have a limited number of chemical control tools to selectively remove nuisance fish. The present study examined whether Antimycin-A (antimycin) wax encapsulated microparticles could cause selective...

Data release for toxicity of Antimycin A incorporated management bait for grass carp Data release for toxicity of Antimycin A incorporated management bait for grass carp

The goal of this study was to develop and examine whether a management bait that can be used for selective control of grass carp. Our objectives were to 1) quantify the water-based 24-h LC50 of Antimycin-A for grass carp and rainbow trout, 2) quantify the 96-h LD50 of orally administered Antimycin-A laden bait for grass carp and rainbow trout, 3) quantify the leaching rate of Antimycin-A...

A novel tool to selectively deliver a control agent to filter-feeding silver and bighead carp A novel tool to selectively deliver a control agent to filter-feeding silver and bighead carp

Invasive carp pose substantial economic and ecological damage when populations are widespread in freshwater systems within the United States. Resource managers in the United States have few chemical control tools to selectively remove nuisance fish. This study examined whether Antimycin–A (antimycin) wax encapsulated microparticles could cause selective lethality in invasive carps. The...

Toxicity of a management bait for grass carp (Ctenopharyngodon idella) incorporated with Antimycin A Toxicity of a management bait for grass carp (Ctenopharyngodon idella) incorporated with Antimycin A

No current technology can specifically target grass carp (Ctenopharyngodon idella) for control within aquatic ecosystems. Rotenone and Carbon Dioxide-Carp are currently the only available registered pesticides for grass carp; they are nonselective and typically applied throughout the water, equally exposing target and native species. A more selective control tool or pesticide application...

Tests in a semi-natural environment suggest that bait and switch strategy could be used to control invasive Common Carp Tests in a semi-natural environment suggest that bait and switch strategy could be used to control invasive Common Carp

Common Carp (Cyprinus carpio Linnaeus, 1758), is a highly invasive species that has had profound effects on biodiversity and ecosystem services. Many Carp management methods have been applied including physical removal, pesticide treatments of whole lakes, and water drawdowns. Herein, we tested key elements of a potential “bait and switch” approach in which corn could be used to induce...

Profiles of digestive enzymes of two competing planktivores, silver carp and gizzard shad, differ Profiles of digestive enzymes of two competing planktivores, silver carp and gizzard shad, differ

Typically, studies in digestive physiology in fish focus on a few enzymes and provide insight into the specific processes of the enzyme in a targeted species. Comparative studies assessing a wide number of digestive enzymes on fishes that compete for food resources are lacking, especially in the context of an introduced species. It is generally thought that the invasive silver carp (SVC...

Assessing the efficacy of corn-based bait containing antimycin-a to control common carp populations using laboratory and pond experiments Assessing the efficacy of corn-based bait containing antimycin-a to control common carp populations using laboratory and pond experiments

Strategic use of oral toxicants could allow for practical and sustainable control schemes for the invasive common carp (Cyprinus carpio, or ‘carp’) if a toxicant selectively targeted carp and not native species. In this study, we incorporated antimycin-a (ANT-A), a known fish toxicant, into a corn-based bait and conducted a series of experiments to determine its toxicity, leaching rate...

Digestive physiology comparisons of aquatic invertebrates in the Upper Mississippi River Basin Digestive physiology comparisons of aquatic invertebrates in the Upper Mississippi River Basin

Limited information is available on the composition of digestive enzymes present in unionid mussels and the zebra mussel, Dreissena polymorpha. Available information is nearly exclusive to species used for culture purposes. A commercially available enzyme assay kit was used to examine the effect of habitat within an ecosystem, season, and species on the activities of several digestive...

Preliminary characterization of digestive enzymes in freshwater mussels Preliminary characterization of digestive enzymes in freshwater mussels

Resource managers lack an effective chemical tool to control the invasive zebra mussel Dreissena polymorpha. Zebra mussels clog water intakes for hydroelectric companies, harm unionid mussel species, and are believed to be a reservoir of avian botulism. Little is known about the digestive physiology of zebra mussels and unionid mussels. The enzymatic profile of the digestive glands of...
