American Eel Subpopulation Characteristics in the Potomac River Drainage, Virginia
The demographic characteristics of American eels (Anguilla rostrata) are believed to vary with latitude and distance inland from the ocean; eels are generally thought to increase in length, age, and the proportion of females in inland and more northerly areas. Understanding this variation is …

American Eel Distibution and Growth in Selected Tributaries of the James River
… reach of Shoe Creek, Virginia, and captured 66 American eels. Eels were weighed (g) and measured (mm) and 61 individuals were implanted with Passive Integrated Transponders (PIT). Size distribution of the tagged eels ranged from 174-775 mm total length. The team returned to Shoe Creek in October …

Assessment of local abundance, demographics, health and exploitation of Chesapeake Bay American eel
… Bay supports the largest U.S. harvest of American eel <italic>Anguilla rostrata</italic>, yet little is known about the underlying production rates sustaining harvests. Demographic attributes were compared between six sub-estuaries and with an unexploited population in the Hudson River. A …

Selection of benthic habitat by yellow-phase American eels (Anguilla rostrata)
… examines habitat preference of yellow-phase American eels (Anguilla rostrata) and relationships between age and length with that preference. The thesis is comprised of two chapters: (1) an introduction and literature review on American eel life history, their habitat selection, and the study …

Feeding Ecology of Invasive Catfishes in Chesapeake Bay Subestuaries
… species of concern. Species of concern include American Shad, American Eel, and river herring, which are imperiled, and blue crab, which support valuable fisheries in Chesapeake Bay. Predation of American Shad, American Eel, and river herring was rare (max predicted occurrence in Blue Catfish …

Tissue enzyme changes in air-exposed American eels.
American eels (Anguilla rostrata) are known to leave the water for excursions onto land despite lacking specialized air breathing organs. Other studies have established that the eel suffers from acidosis and hypoxemia as a result of this air exposure, but the survival of the eels despite these …

Embryotoxicity of dioxin-like chemicals extracted from American eels (Anguilla rostrata) from the St. Lawrence River System
The American eel (Anguilla rostrata) has suffered a serious population decline in Lake Ontario since the early 1980s due to a decline in recruitment of juveniles migrating from the Sargasso Sea. This has resulted in the closure of the Lake Ontario fishery in 2004 and its listing as endangered under …

Involvement of Cytochrome P450 1A in the toxicity of aryl hydrocarbon receptor agonists : alteration arachidonic acid metabolism and production of reactive oxygen species
… CYP1A induction in endothelial cells of the American eel (Anguilla rostrata), a site which may be particularly susceptible to alterations in AA metabolism and ROS production, was described. Eel liver CYP1A responded to BP, 13-naphthoflavone and TCB in a dose-dependent fashion, and induction …

Effects of abiotic and biotic factors on population dynamics of brook trout (<i>Salvelinus fontinalis</i>) within Shenandoah National Park, Virginia
… compared to other categories. For example, American eel (Anguilla rostrata) abundance consistently had a negative relationship with brook trout abundance. In Chapter 2, I use linear models and long-term fish survey data from the U.S. Forest Service (1994-2022) to investigate the relationship …
