California Department of Parks and Recreation. Division of Boating and Waterways.

As part of its mission, the Division of Boating and Waterways manages the Quagga and Zebra Mussel Infestation Prevention Grant Program, which supports preventative plans that help protect California’s reservoirs from a dreissenid mussel infestation. California State Parks Division of Boating and Waterways (DBW) will accept applications for the 2021 Quagga and Zebra Mussel Infestation Prevention Grant Program: March 22, 2021 - April 30, 2021, subject to available funds.

Minimum Eligibility Requirements:
Grant applicant must own/manage any aspect of the water in a reservoir where recreational activities are permitted; Grant applicant must demonstrate that the reservoir is uninfested with dreissenid mussels; and the reservoir must be open to the public.

Texas Parks and Wildlife Department.

The Texas Parks and Wildlife Department (TPWD) reports that invasive quagga mussels have been detected for the first time in Texas. The quagga mussel discovery was made by National Park Service (NPS) staff at the International Amistad Reservoir in the Rio Grande basin along the Texas-Mexico border near Del Rio. Quagga mussels are a close relative of the zebra mussel, which has invaded 33 Texas lakes across six river basins since it was first introduced in Texas in Lake Texoma in 2009. In addition to being the first detection of quagga mussels in Texas waters, this is also the first finding of any invasive mussel species in the Rio Grande basin.

TPWD and partners monitor for invasive mussels in Texas lakes, but anyone who finds them in lakes where they haven’t been found before should report them immediately by emailing photos and location information to AquaticInvasives@tpwd.texas.gov.

The Rapid Response Plan for Management and Control of the Chinese Mitten Crab is intended to guide efforts to mitigate the further introduction and spread of the Chinese mitten crab in the northeastern United States and Canada. Due to the unique challenges of invasive species introductions to marine and coastal ecosystems, the mitten crab and other existing and potential marine invasive species are more difficult and often more costly to manage or control than freshwater aquatic or terrestrial invasive species. This document focuses on the use of early detection and rapid response as a tool to prevent the introduction and spread of Chinese mitten crabs and other crabs belonging to the genus Eriocheir throughout northeastern United States and Atlantic Canada. The primary goal of this plan is to provide information needed to support local, state, and regional efforts to prevent and control the spread of Chinese mitten crabs throughout northeastern United States and Atlantic Canada. For more information on the development of this plan, see Early Detection and Rapid Response Plan for the Invasive Chinese Mitten Crab.

Kansas Department of Wildlife & Parks.

Widespread sampling for invasive crayfish had never occurred in Kansas lakes – that is, until the Kansas Department of Wildlife and Parks (KDWP) recently funded a university project focused on the freshwater crustacean. KDWP's Aquatic Nuisance Species Program and Ecological Services section funded the project with the overarching goal of establishing sampling protocols that could then be used for long-term monitoring of both native and invasive crayfish in Kansas. During capturing efforts at McPherson State Fishing Lake – one of several small waterbodies slated to be inspected in the state – university researchers collected multiple Rusty Crayfish. Rusty Crayfish have not previously been documented in the wild in Kansas, making this official "discovery" the first of its kind.

Anglers, boaters and watersport enthusiasts are encouraged to keep their eyes open for this invasive species, which can be identified by its trademark large, black-tipped claws and rust-colored spots on its upper shell. If one is discovered, freeze it in a sealed plastic bag, note the date and location of capture, and contact KDWP's Emporia Research and Survey Office at (620) 342-0658.

The Idaho Department of Agriculture (ISDA) has confirmed the presence of quagga mussel in the Mid-Snake River. Quagga mussel larvae was first detected in the Snake River near Twin Falls on September 18, 2023, by routine monitoring conducted by the ISDA. If nothing were done, quagga mussels would quickly take over waterways. They would irreparably harm water use in Idaho. These findings mark the first time a rapid response plan has been put into action for quagga mussels in Idaho.

Watercraft are the largest vectors for spreading aquatic invasive species (AIS), such as quagga and zebra mussels into new waterways, making boat inspections a vital aspect of protecting Lake Tahoe and other nearby water bodies.
