Northern Snakeheads in New York City
Northeastern Naturalist, 2016Abstract A population of Channa argus (Northern Snakehead) was discovered in the Meadow/Willow lakes system in Queens, NY, in 2005 and monitored annually by electrofishing through 2013. Despite apparently suitable habitat, a variety of forage fish species, and rapid early growth by Snakeheads, the Meadow/Willow Snakehead population has not rapidly ...

Acute Toxicity of 5% Rotenone to Northern Snakeheads
North American Journal of Fisheries Management, 2006Abstract The confirmation of northern snakeheads Channa argus caught by an angler in a private pond in Maryland resulted in significant media attention and generated numerous resources for risk identification and the development of action plans to prevent the introduction of this nonnative species into state waters. Rotenone was selected

Northern Snakeheads in the Tidal Potomac River System
Transactions of the American Fisheries Society, 2005AbstractA population of northern snakeheads Channa argus was documented within a 23‐km reach of the main‐stem tidal freshwater Potomac River and associated tributaries in 2004. Twenty northern snakeheads were collected with a variety of gears, including hook and line and electrofishing.

Expansion of Northern Snakehead in the Chesapeake Bay Watershed
Transactions of the American Fisheries Society, 2018AbstractNorthern Snakehead Channa argus, a nonnative species to North America, was discovered in 2004 in tidal freshwater of the Potomac River, the second largest drainage of the Chesapeake Bay watershed. Since then Northern Snakehead has expanded its range throughout much of Maryland's portion of the Chesapeake Bay watershed.

Expansion of a Northern Snakehead Population in the Potomac River System
Transactions of the American Fisheries Society, 2007AbstractA population of northern snakeheads Channa argus was documented in the Potomac River system in 2004. The expansion of this population was monitored from 2004 to 2006. Boat electrofishing mean catch per unit effort increased significantly each year from 0.2 fish/h in 2004 to 6.1 fish/h in 2006 (analysis of variance [ANOVA]: P = 0.01).

A Comparison of Different Age Estimation Methods for the Northern Snakehead
North American Journal of Fisheries Management, 2013Abstract We used otoliths, scales, pectoral fins, dorsal fins, basioccipital bones, opercular bones, interopercular bones, vertebrae, teeth, and cleithra sampled from 221 known-age Northern Snakeheads Channa argus argus representing five age-groups to determine and compare age estimation methods for this species.

Insight into Age and Growth of Northern Snakehead in the Potomac River
North American Journal of Fisheries Management, 2013Abstract A Northern Snakehead Channa argus population was documented in the Potomac River system in 2004. Since that time, the population has expanded in range and number, yet relatively little is known about key population variables including age and growth.

Transcriptome sequencing and de novo analysis of the northern snakehead, Ophiocephalus argus
Journal of Genetics, 2019Northern snakehead, Ophiocephalus argus Cantor, is an endemic freshwater fish in China. However, wild stocks of O. argus are dwindling sharply. Further, water conservancy projects, environmental pollution and human activities have caused the decrease of wild stocks, which has attracted much attention.

Harvest of Northern Snakehead with Bowfishing in Maryland
Integrative And Comparative BiologySynopsis Illegal introductions in North America have helped establish populations of Northern Snakehead (Channa argus), an invasive freshwater fish from Asia. Once targeted for eradication, widespread establishment of populations in the Chesapeake Bay watershed has now led management to prioritize mitigation.

Trends in Abundance of Northern Snakeheads in Virginia Tributaries of the Potomac River
Transactions of the American Fisheries Society, 2016AbstractA population of nonnative Northern Snakeheads Channa argus was documented in the Potomac River system during 2004. We estimated relative abundance (fish/h of boat electrofishing) for up to 12 years in four Virginia creeks within and downstream of the original area of colonization.
