Canadian Food Inspection Agency.
The Canadian Food Inspection Agency (CFIA) has confirmed the presence of Whirling Disease in fish in Johnson Lake in Banff National Park. This is the first case of whirling disease in Canada. The federal and provincial governments will work together to develop an appropriate response plan as additional information about the disease situation is confirmed.

Hydrilla, considered one of the world's most invasive aquatic plants, has been detected for the first time in Michigan. The Department of Environment, Great Lakes and Energy confirmed two small populations of the plant in adjacent private ponds on residential properties in Berrien Springs in Southwest Michigan.

The small patches of hydrilla (Hydrilla verticillata) were discovered during routine monitoring following treatment for another invasive plant, parrot feather, which was found in the pond in 2020. Both species are prohibited in Michigan, meaning it is unlawful to sell, possess or import them into the state, and both are on Michigan’s invasive species watch list due to their potential environmental threat. Any suspicious aquatic plants should be reported as soon as possible to EGLE-WRD-AIP@Michigan.gov. Include close-up photos and provide the location of the detection in your report. More information on identifying and reporting invasive aquatic plants can be found at Michigan.gov/Invasives.

Idaho Department of Agriculture.
Quagga mussels were found in the Snake River in September 2023. Immediately afterwards, Idaho Fish and Game assisted the Department of Agriculture in their evaluation of potential treatments to eliminate the mussels, and Idaho Fish and Game quantified the fish populations found in the six-mile stretch of river where the mussels were found, and where the treatment would occur. Biologists quickly learned that the treatment caused high mortality in certain species, while others survived quite well.

USDA. ARS. Tellus.
Research and commerce use a two-pronged ‘fork’ approach to deal with invasive fish. As many anglers know, carp are not welcome when found dangling from the hook. Classified by U.S. government as an invasive species and known colloquially as a “trash fish,” carp can take over and devastate every watery environment they enter. They’re not particularly well known in this country as good eating fish, either. To help curb the numbers of invasive fish, researchers and commerce are using a two-pronged ‘fork’ approach to deal with the invasive fish.

Arkansas Game & Fish Commission.
Giant threats to Arkansas's fish and water are lurking under the surface somewhere right now. The Arkansas Game and Fish Commission needs boaters' help in stopping these terrors before they spread any further. Matt Horton, the AGFC's Aquatic Nuisance Species program coordinator, says 36 aquatic nuisance species have been documented in Arkansas, including plants, fish, mussels and other types of organisms. Some of the more well known species include giant salvinia, silver carp, northern snakeheads and zebra mussels, but these are just a few of the species that can pose significant ecological and economic harm, as well as a risk to human health.

Just like when fighting a virus, Horton says the best plan of attack is to prevent it from spreading to new areas. Here are some ways everyone can fight aquatic nuisance species in Arkansas to keep our waters healthy and accessible for angling and boating enjoyment.
