Invasive Carp

Invasive Carp Control: Carbon Dioxide Carbon dioxide (CO2) is being evaluated as a new fishery chemical for general aquatic invasive species control. Most research has focused on its effectiveness as a behavioral deterrent and lethal control or invasive carps. However, because CO2 is generally non-selective, there is potential for this new control chemical to be applied across a wide range of...

Increased threat of Invasive carp entering the Great Lakes and spreading to other basins such as the Upper Mississippi River and Ohio River basins, has led to increased prevention and control efforts since 2010. Successful management of this invasive species requires methods to contain future spread, reduce population levels, and minimize their effects. In collaboration with partners, USGS...

USGS scientists monitored the distribution of the Invasive carp populations within the pools of the Illinois River to help identify favorable habitats. Sharp contrasts in habitat, flow conditions, water quality, and food supply between the Marseilles and Dresden Island Pools and the Chicago Area Waterway System may be acting as controlling factors to the stalled upstream movement of Invasive carp...

The objective of this project is to develop carbon dioxide (CO2) as a new tool for controlling Invasive carp migration. More specifically, navigational structures are potential management pinch-points to block the spread of Invasive carps within major rivers throughout the United States. Carbon dioxide has shown promise as a behavioral deterrent for Invasive carps and could be a useful non...

The long-term goal of this project is to develop acoustic deterrents to prevent the upstream migration of Invasive carp to the Great Lakes.

The US Geological Survey is studying life history and habitats of invasive Grass Carp with a goal of developing strategies and tactics to greatly reduce or possibly eradicate Grass Carp from Lake Erie.

Over 180 and 140 aquatic invasive species (AIS) have been introduced into the Great Lakes and Upper Mississippi River basins, respectively, with threats of new invasions always on the horizon. Sea lamprey, zebra mussels, and invasive carps are just a few examples of AIS whose abilities to alter aquatic habitats and disrupt food cycles threaten many outdoor recreation opportunities and ecosystems...

Increased threat of Invasive carp entering the Great Lakes and spreading to other basins such as the Upper Mississippi River and Ohio River basins, has led to increased prevention and control efforts since 2010. In collaboration with partners, USGS scientists are testing early detection methods and technologies to enhance the ability of agencies to manage Invasive carp to minimize their influence...

Increased threat of Invasive carp entering the Great Lakes and spreading to other basins such as the Upper Mississippi River and Ohio River basins, has led to increased prevention and control efforts since 2010. USGS Invasive carp biology and life history research has led to the development of models, tools and strategies to better understand the risk of Invasive carp establishment and survival...
