A virus that can cause disease in largemouth bass has now been identified in otherwise apparently healthy northern snakeheads taken from two Potomac River tributaries in Virginia. This is the first time that the pathogen, known as largemouth bass virus, has been reported in northern snakeheads. While the significance of this finding is not yet known, the study's lead author, said it raises the possibility that snakeheads could be reservoirs of this virus and capable of transmitting it to bass populations in the Chesapeake Bay watershed.

Asian Carp Regional Coordinating Committee.

The Obama Administration announced a series of new measures to protect the Great Lakes from Asian carp, building on the comprehensive plan the Administration created in 2010 to prevent this invasive species from developing self-sustaining populations in the Great Lakes. The updated plan adds several initiatives to the proactive effort to combat Asian carp, including testing and deployment of new physical and chemical control tools, strengthening the electric barrier system in the Chicago Area Waterway System, and constructing a new project to physically separate the Great Lakes and Mississippi River basin at Eagle Marsh near Fort Wayne, Indiana.

Washington State University.

Researchers at Washington State University are preparing for a Northwest invasion of the zebra mussel - a small, distinctly striped and rather tenacious freshwater mollusk that can quickly encrust underwater surfaces. The mussels have caused significant damage in other parts of the country and pose an enormous risk to the hydroelectric infrastructure, recreational facilities and unique ecological system of the Columbia River Basin. The Columbia River Basin is one of the last major river systems in the U.S.still free of zebra mussels and the closely related quagga mussels; but possibly not for long. Once they are established in the water, they are almost impossible to eradicate.

Environmental Protection Agency.

The EPA issued a final vessel general permit regulating vessel discharges from commercial vessels, including ballast water, to protect the nation's waters from ship-borne pollutants and reduce invasive species in U.S. waters. The permit imposes international cleanliness standards that the Coast Guard also adopted in regulations it issued last year.

Channeled apple snail was imported for aquaculture and the aquarium trade and was introduced to Hawaii in 1989. Channeled apple snail damages rice and taro production by feeding on seedlings and competes with native apple snails and other species.

University of California - Davis.

Well-intentioned children and aquarium hobbyists seeking to "free" their pet fish down a toilet bowl or into a local waterway may inadvertently be contributing to the threat of invasive species downstream, according to a new report from the University of California, Davis. See Aquatic Invasive Species Vector Risk Assessments for more information.

Phragmites australis, an invasive species of plant called common reed, grows rapidly into dense stands of tall plants that pose an extreme threat to Great Lakes coastal wetlands. Early treatment is the key to controlling Phragmites. Scientists have mapped the U.S. coastline of all five Great Lakes using satellite technologies. The Phragmitesmap is the first of its kind. It is "a highly accurate data set that will allow national, regional and local managers to visualize the extent of Phragmitesinvasion in the Great Lakes and strategically plan efforts to manage existing populations and minimize new colonization."

Scientists from NOAA's National Centers for Coastal Ocean Science (NCCOS) and their partners have teamed up to create specific guidelines for coastal managers to control the spread of invasive lionfish. The new manual, Invasive Lionfish: A Guide to Control and Management, includes the best available science and practices for controlling lionfish in marine protected areas, national parks, and other conservation areas. By following suggestions in the publication, resource managers can develop effective local control plans.

The U.S. and Canada signed an accord to protect the Great Lakes, the world's largest freshwater system. The agreement, last updated in 1987, addresses critical health issues in the Great Lakes region and is a model of binational cooperation to protect water quality.

A Chinese mitten crab was recently found in Connecticut waters. This is the first confirmed report of this highly invasive crab in Connecticut waters. In late June, the crab was collected from the Mianus Pond fishway on the Mianus River. Individuals finding a crab that they suspect to be a Chinese mitten crab should keep the crab on ice or freeze it (please do not release the crab), note the exact location it was found and report it to officials.

Florida Fish and Wildlife Conservation Commission.
FWC recently made changes that will increase lionfish harvesting opportunities, which are currently in effect through Aug 2013: a recreational fishing license is not required for recreational fishers targeting lionfish while using a pole spear, a Hawaiian Sling, a handheld net or any spearing device that is specifically designed and marketed exclusively for lionfish. There is no recreational or commercial harvest bag limit for lionfish. Learn more about lionfish or read the new State of Florida Executive Order 12-12 (PDF | 167 KB) on lionfish harvesting.

U.S. Senator Sherrod Brown.

Bipartisan legislation to stop Asian carp from destroying the Great Lakes' ecosystem has passed both houses of Congress and is now poised to become law. The Stop Invasive Species Act, of which Brown was an original cosponsor, would require the expedited creation of a plan to block Asian carp from entering the Great Lakes through a number of rivers and tributaries across the Great Lakes region.

Great Lakes Coalition. Healing Our Waters.

State and federal agencies recently completed construction of a $1.6 million sea lamprey barrier in Trail Creek, a Lake Michigan tributary in northern Indiana. The barrier will prevent sea lamprey from spawning in the creek, which will reduce the number of these monstrous, blood-sucking invaders in Lake Michigan. The barrier and other efforts to control sea lamprey are paramount to efforts to maintain a healthy Great Lakes fishery. Each sea lamprey can consume up to 40 pounds of fish during its time in the lakes.

Great Lakes Coalition. Healing Our Waters.
Congress introduced new bills aimed at combating the spread of Asian carp into the Great Lakes. The legislation directs the U.S. Army Corps of Engineers to complete within 18 months its study on how to separate the Great Lakes and Mississippi watersheds to block the advance of the non-native Asian carp. The voracious fish are within miles of Lake Michigan. Scientists fear that an Asian carp invasion into the Great Lakes could devastate the region's $7 billion sport and commercial fishery. The legislation updates the Stop Asian Carp Act of 2011, which was introduced last year. For more information on the bills introduced, see Congressional Bills - 112th Congress.
