Lampricides are usually ordered and produced in large quantities every two or three years depending on projected need. The majority of the lampricides are used within three years. The chemical stability of lampricides stored under normal standard operating procedures is not known beyond three years. Product that has been stored for more than 3 years has to be tested for percent active ingredient...

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).

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...

This study is designed to be a high-throughput alternative to traditional methods of using whole fish assays to screen compounds for toxicity. This approach involves an initial pre-screening of a chemical databank to select molecules possessing characteristics identified as predictive criteria for potential toxicity to the fathead minnow, followed by cytotoxicity screening of selected compounds...

Expansion of bigheaded carps Hypophthalmichthys spp. throughout North American waterways have prompted the need for control systems that can alter their movement and/or behavior. The avoidance response of bigheaded carps to the sound of an outboard motor (0.06-10 kHz) has lead researchers to investigate sound as a means to manipulate their movements.

The results from this study will provide the base for future human food safety studies that are required by the U.S. Food and Drug Administration to approve an immediate release fish sedative. These data will support the potential approval of an immediate release fish sedative that can be efficiently used by fishery managers throughout the U.S.

The results from this study will provide the base for drug residue studies that are required by the U.S. Food and Drug Administration to evaluate the risk to people that might eat a recently sedated fish. These data will support the potential approval of an immediate release fish sedative that can be efficiently used by fishery managers throughout the U.S.

The results from this study will provide data that is necessary to support the potential approval of a sedative that will allow hatcheries to transport fish more efficiently.

The results from this study will provide data that is necessary to support the potential approval of a drug that will allow producers to raise fish more efficiently.

The results from this study may lead to an expansion of the SLICE® label allowing for treatment of freshwater-reared fish infested with copepods. Label expansion would enhance production on hatcheries throughout the United Sates.

Impact of UMESC Science The results from this study may lead to an expansion of the 35% PEROX-AID® label allowing for the use of the drug to control coolwater and warmwater finfish mortality associated with a parasitic infestation. Label expansion would enhance coldwater finfish production on all hatcheries throughout the United Sates.
