Database and web application for invasive carp catch data (Illinois River Catch Database)

Four types of invasive carp are currently found in the United States: black, grass, silver, and bighead carps. These species are fast growing, prolific feeders that out-compete native fish species and drastically alter the natural ecosystems they invade. To prevent the spread of invasive carp into the Great Lakes, the multi-agency Asian Carp Regional...

Database and web application for invasive carp telemetry data (FishTracks)

Four types of invasive carp fish species, are currently found in the United States: black, grass, silver, and bighead carps. These species are fast growing, prolific feeders that out-compete native fish species and drastically alter the natural ecosystems they invade. To prevent the spread of invasive carp into the Great Lakes, the multi-agency Asian Carp...

Assessing Impacts of Emerging and Established Diseases to Aquatic Ecosystems

Native freshwater mussels play a critical role in aquatic environments and are considered “ecosystem engineers” and indicators of water quality by constantly filtering water. Populations of native freshwater mussels have declined in recent years, and this decline has been attributed to factors such as habitat degradation, pollution, and invasive species, among others. The importance of these...

Management Tools for Dreissenid Mussels

Dreissenid mussels have posed an aquatic invasive species challenge in the United States since their arrival in the Great Lakes in the 1980s. Zebra (Dreissena polymorpha) and Quagga (D. bugensis) mussels are filter feeders with high reproductive capacity. Their behaviors result in altered nutrient cycles, shifts in trophic structures, and extirpation of some native species in...

Evaluation of Carbon Dioxide to Control Dreissenid Mussels

Management Tools for Dreissenid Mussels

Carbon dioxide (CO2) has been suggested as a chemical control for a variety of invasive aquatic organisms, including Asian Carp. USGS researchers and partners evaluated the efficacy of low CO...

Evaluation of Copper as a Control Agent for Invasive Mussels

Management Tools for Dreissenid Mussels

USGS researchers and partners conducted an experimental application of low dose copper, as EarthTecQZ, to a bay in Lake Minnetonka, Minnesota.  The veliger density and settlement were compared to that...

Environmental DNA (eDNA) Data Management

The environmental DNA (eDNA) samples collected, processed, and sequenced by the Upper Midwest Environmental Sciences Center (UMESC) and partner agencies are being archived in a cloud-based database application. Consolidating eDNA data will significantly improve researchers and managers ability to visualize, analyze, and integrate sequence data as a monitoring and early detection system for...

Exploring Invasive Plant Detection with Small Unmanned Aircraft Systems and Sensors

Spatial maps showing locations of invasive plants equip land managers with a valuable tool. Properly acquired aerial imagery provides vegetation mappers or machine learning software an efficient venue to map invasive plants, in contrast to the effort required for an on-the-ground census of plants. Small Unmanned Aircraft Systems (sUAS) can yield quick acquisition of aerial imagery over...
