The Pennsylvania Fish and Boat Commission (PFBC) is urging anglers to report and dispose of any invasive Northern Snakehead fish that may be caught in the lower Susquehanna River. This advisory follows the documented movement of 21 Northern Snakeheads past the Conowingo Dam into the Conowingo Pool, a 14-mile-long section of the Susquehanna River located between the Conowingo Dam in Maryland and the Holtwood Dam in Pennsylvania. Anglers are reminded that possession, transport, and importation of a live snakehead is unlawful in both Pennsylvania and Maryland. Any of these invasive fish that are caught should be killed and disposed of properly or consumed. Anglers who suspect they have caught a snakehead are encouraged to NOT release it, and report it to the PFBC at (610) 847-2442 or by sending an email to tgrabowski@pa.gov. For more information on Northern Snakeheads in Pennsylvania, including an identification guide, visit the PFBC snakehead resource page.

The Asian Carp Regional Coordinating Committee announced the release of its 2021 Asian Carp Action Plan, a comprehensive portfolio of projects focused on Great Lakes protection.

The U.S. Fish and Wildlife Service published a final rule in the Mar 22 Federal Register officially adding the bighead carp to the federal injurious wildlife list. The final rule codifies the Asian Carp Prevention and Control Act (S. 1421), signed into law by President Obama on Dec 14, 2010. The injurious wildlife listing means that under the Lacey Act it is illegal to import or to transport live bighead carp, including viable eggs or hybrids of the species, across state lines, except by permit for zoological, education, medical, or scientific purposes.

A study conducted by Maryland Department of Natural Resources Biologist Dr. Joseph Love illuminates one of the biological factors that could be contributing to Chesapeake Channa’s efficient spread through Maryland’s waters. The study, published in the July 2024 edition of Northeastern Naturalist, found that the majority of female Chesapeake Channa, also known as northern snakehead, collected from the upper Chesapeake Bay carried eggs in two distinct sizes, suggesting those fish could spawn twice a year.

Following more than two years of consumer research and planning, the State of Illinois unveiled "Copi," the new name for Asian carp, which is a play on “copious” – as that’s exactly what these fish are. By one estimate, 20 million to 50 million pounds of Copi could be harvested from the Illinois River alone each year, with hundreds of millions more in waterways from the Midwest to the Gulf Coast. The new name and brand are designed to address public misconceptions about this delicious top-feeding fish, which is overrunning Midwest waterways.

Copi are mild, clean-tasting fish with heart-healthy omega-3s and very low levels of mercury. Increased consumption will help to stop them from decimating other fish populations in the Great Lakes and restore an ecological balance to waterways down stream.

The Chesapeake Bay Nutria Eradication Project (CBNEP) announced at an event at Blackwater National Wildlife Refuge today that Maryland is now free of the exotic, invasive nutria. The U.S. Fish and Wildlife Service (USFWS), U.S. Department of Agriculture’s Wildlife Services (WS), and Maryland Department of Natural Resources (DNR) have worked more than 20 years to make this difficult task -- never accomplished before on this scale -- a success.

The Pennsylvania Fish and Boat Commission (PFBC) announced that it has conducted targeted invasive carp sampling in Presque Isle Bay, Erie County, after the U.S. Fish and Wildlife Service (USFWS) detected the presence of Silver Carp environmental DNA (eDNA). While no physical invasive carp specimens have been detected, the PFBC has requested that the USFWS collect additional water samples from Presque Isle Bay in the fall when more favorable environmental conditions are present for eDNA sampling. Members of the public can report sightings of aquatic invasive species to the PFBC using its online form.

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.

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.

The Government of Canada is investing up to $20 million over five years, and ongoing, to Canada's Asian Carp Program to continue prevention efforts through early warning surveillance, partnering and outreach activities. This funding will allow Fisheries and Oceans Canada to expand the Asian Carp Program to increase protection of our Great Lakes and preserve our fisheries.

Grass carp, one of four species of Asian carp, has the potential to disrupt the Great Lakes ecosystem and economy unless their spread is stopped, according to a report released by Fisheries and Oceans Canada with support from the Great Lakes Fishery Commission and the Ontario Ministry of Natural Resources and Forestry. The socio-economic study concludes that, in addition to the significant ecological threat that is posed by the presence of grass carp in the Great Lakes, there would also be economic, social and cultural ripple effects.

In a letter [PDF, 396 KB] to the Chairs and Ranking Members of the U.S. Senate Committee on Environment and Public Works and the U.S. House Committee on Transportation and Infrastructure, the Governors of the eight Great Lakes States have called on the U.S. Congress to provide full federal funding in the 2022 Water Resources Reform and Development Act for the remaining design, construction, operation, and maintenance costs of the Brandon Road Lock and Dam project. The project is intended to prevent invasive carp from migrating up the Mississippi River and entering and colonizing in the Great Lakes.

The Great Lakes Sea Grant Network has released a comprehensive and coordinated outreach and education report on Asian carp in the region. The document includes information on carp life history, movement and behavior, monitoring, control, ecosystem impacts and gaps in current knowledge that need to be addressed further. The plan’s development was funded by the Great Lakes Restoration Initiative through the Asian Carp Regional Coordinating Committee. See final report (Publication OHSU-TB-1511) Education and Outreach on Asian Carp [2017; PDF, 5.6 MB].

Black carp, which are an invasive fish species in North America, are now known to be established in the wild in parts of the Mississippi River basin. A new study co-authored by the U.S. Geological Survey (USGS) is the first to identify an established population—meaning they are naturally reproducing and living to adulthood— of wild black carp in any location across the U.S.

When a black carp is captured in the wild, it can be reported to the USGS Nonindigenous Aquatic Species database. That tool compiles information on and can be used to track the status of other aquatic invasive species as well. The USGS is involved in many invasive species projects across the U.S. and its territories. Learn more by visiting the USGS Invasive Species website or the USGS Invasive Carp section.

The Invasive Carp Regional Coordinating Committee (ICRCC) announced the release of its 2022 Invasive Carp Action Plan, a comprehensive portfolio of 60 projects focused on Great Lakes protection. The Action Plan serves as a foundation for the work of the ICRCC partnership — a collaboration of 28 U.S. and Canadian federal, state, provincial, tribal, regional, and local agencies.

The Invasive Carp Regional Coordinating Committee (ICRCC) is pleased to announce the release of its 2023 Invasive Carp Action Plan, a comprehensive portfolio of more than 50 projects focused on Great Lakes protection. The action plan serves as a foundation for the work of the Invasive Carp Regional Coordinating Committee partnership, a collaboration of 26 U.S. and Canadian federal, state, provincial, tribal, regional and local agencies.

The Texas Parks and Wildlife Department (TPWD) received a report in late June that an invasive silver carp had been spotted in Choctaw Creek, a Texas tributary of the Red River approximately 15 miles downstream from Lake Texoma. "These are the first reports of silver carp from Texas waters, although they have previously been found in other areas of the Red River including just downstream from Lake Texoma in Oklahoma waters in 2019," said Dan Bennett, TPWD fisheries management biologist. "Invasive carp pose a significant risk to Lake Texoma’s ecosystem and boaters and there is adequate flow and upstream river area for them to become established and reproduce in the lake if introduced."

Anyone who catches either silver carp or bighead carp in Texas waters is asked to report the sighting with location information and photos to AquaticInvasives@tpwd.texas.gov. Silver and bighead carp are prohibited exotic species in Texas and must be killed upon possession by beheading, gutting, gill-cutting or other means or placed on ice. Neither species can be possessed live.

On August 27, an angler caught a northern snakehead from Reservoir Pond in Canton, Massachusetts. After obtaining and analyzing the specimen, MassWildlife confirmed this fish was a snakehead, an invasive species in Massachusetts. This fish was most likely released by a pet owner when it grew too large for its aquarium. Possession and liberation of snakeheads are both illegal in Massachusetts. Transferring exotic fish into local waterways can cause a host of problems, including competition with native species and spread of disease. This recent catch is the fifth confirmed snakehead documented in Massachusetts since 2002. All snakeheads found in Massachusetts were adults, and MassWildlife has found no evidence of reproduction at any of the locations where the snakeheads were caught.

Anglers may confuse snakeheads with other native species like bowfin. Anyone who captures a fish that can be confidently identified as a snakehead should keep the fish, kill it, and report it to MassWildlife by emailing mass.wildlife@mass.gov or calling (508) 389-6300. MassWildlife encourages anglers who are less certain about the species of fish they have caught to send photos showing various angles of the fish. Under no circumstance should a suspected snakehead be transported to another location until identification is confirmed.

The Georgia Department of Natural Resources' Wildlife Resources Division confirmed someone found a northern snakehead in early October in a pond on private property in Gwinnett County, marking the first time the invasive fish has been found in the state. Fishermen who find a northern snakehead should take pictures, note where it was caught and then report it.

Scientists tallying the economic damage wrought by invasive pests across the world found two species are responsible for more harm than any other.

The American bullfrog and brown tree snake have collectively caused $16.3bn in global damage since 1986. In addition to ecological harm, the invasive pair have ruined farm crops and triggered costly power outages.
