Monitoring The Abundance Of American Shad And River Herring In Virginia's Rivers: 2023 Annual Report, Eric J. Hilton, Patrick E. Mcgrath, Ashleigh Magee, Timothy Hoyt

Reports

This report describes the results of the twenty-sixth year of a continuing study to estimate the relative abundance and assess the status of American shad (Alosa sapidissima) stocks in Virginia by monitoring the spawning runs in the James, York and Rappahannock rivers in spring 2023, evaluating hatchery programs, and contributing to coast-wide assessments (ASMFC 2007, ASMFC 2020). We also report on two fisheryindependent monitoring programs using anchor gillnets in the Rappahannock River (year 6) and a major tributary of the James River, the Chickahominy River (year 9), to determine relative abundance and stock structure for the adult spawning run of …

Virginia Fishery Resource Grant Program 2022, Virginia Institute Of Marine Science, Virginia Fishery Resource Grant Program

Reports

The Virginia Fishery Resource Grant Program (VFRGP) enables members of Virginia’s seafood industries to develop ideas to protect and enhance the Commonwealth’s coastal and marine resources. Since its inception in 1999, the annually funded program has supported 143 projects, five of which were approved to start in 2022. These projects enable members of seafood industries to pursue ideas for increasing efficiency and sustainability that will benefit the entire industry, without personally bearing the cost and high risk. The VFRGP is coordinated by the Virginia Institute of Marine Science, Marine Advisory Program (VIMS MAP), in partnership with Virginia Sea Grant Marine …

Virginia Game Fish Tagging Program Annual Report 2021, Susanna Musick, Lewis Gillingham

Reports

Through 2021, the Virginia Game Fish Tagging Program (VGFTP) has maintained a 26-year database of rec-ords for tagged and recaptured fish. The program is a cooperative project of the Virginia Saltwater Fishing Tournament (VSFT) under the Virginia Marine Resources Commission-(VMRC) and the Virginia Institute of Marine Science (VIMS) of William & Mary (under the VIMS Marine Advisory Program).

The main goal of the program is to train and maintain an experienced group of anglers who volunteer their time to properly tag and release fishes. Data on tagged and recaptured fish are summarized in annual reports.

Evaluating Recruitment Of American Eel, Anguilla Rostrata, In The Potomac River (Spring 2022), Troy D. Tuckey, Mary C. Fabrizio

Reports

American Eel (Anguilla rostrata) is a valuable commercial species along the Atlantic coast of North America from New Brunswick to Florida. Landings from Chesapeake Bay typically represent 60% of the annual United States commercial harvest (ASMFC 2012). American Eel is also important to the recreational fishery as it is often used live as bait for Striped Bass (Morone saxatilis) and Cobia (Rachycentron canadum). In 2021, Chesapeake Bay commercial landings of American Eel (284,297 lbs) were 87% of the U.S. landings of yellow eel (personal communication from the National Marine Fisheries Service, Fisheries Statistics Division). …

Difficult Creek, Difficult Management Choices, W. John Hayden

Biology Faculty Publications

Virginia is blessed with many botanical wonderlands; see Chapter 4 of the Flora of Virginia (Weakley et al. 2012) for thumbnail sketches describing 50 of these special places. One such treasure, Difficult Creek Natural Area Preserve, is home to a thriving population of the 2019 VNPS Wildflower of the year, Ceanothus americanus (New Jersey Tea). Paradoxically, however, our featured wildflower of last year is inextricably linked to a difficult conservation management decision.

Wildflower Of The Year—Cymes, Not Corymbs!, W. John Hayden

Biology Faculty Publications

I hit a snag while composing the text for this year’s wildflower of the year brochure on Wild Geranium, Geranium maculatum. The problem concerned the proper descriptive term for its inflorescence, i.e., the pattern in which its flowers are grouped. In more than one source, I read that, for the family Geraniaceae, inflorescences are cymes (Figures 1 and 2), but those same sources indicated that inflorescences of Geranium maculatum are corymbs (Figure 4). That conflict caused me to scratch my head because cymes and corymbs are fundamentally different kinds of inflorescences.

Monitoring Relative Abundance Of American Shad And River Herring In Virginia Rivers 2015 Annual Report, Eric J. Hilton, Robert Latour, Patrick E. Mcgrath, Brian Watkins, Ashleigh Magee

Reports

Concern about the decline in landings of American shad (Alosa sapidissima) along the Atlantic coast prompted the development of an interstate fisheries management plan (FMP) under the auspices of the Atlantic States Marine Fisheries Management Program (ASMFC 1999). Legislation enables imposition of federal sanctions on fishing in those states that fail to comply with the FMP. To be in compliance, coastal states are required to implement and maintain fishery-dependent and fishery-independent monitoring programs as specified by the FMP. For Virginia, these requirements include spawning stock assessments, the collection of biological data on the spawning run (e.g., age-structure, sex ratio, and …

An Analysis Of Particulate Matter In Central Virginia, Elizabeth Garrett, Arif Sikder

Rice Rivers Center Research Symposium

Virginia is consistently rated as a state with high rates of asthma (Asthma and Allergy Foundation 2014). Although this respiratory disease has many causes, certain air pollutants can be a trigger. The EPA currently identifies, monitors, and regulates seven types of air pollutants. One of these pollutants, particulate matter, can occur both naturally and culturally. The primary anthropogenic cause of particulate matter is fly ash, which is formed during fossil fuel combustion. Different technology installed in the power plant can capture some of the fly ash but these methods are not entirely effective.

This study focused on estimating the ratio …

Local Avian Density Influences Risk Of Mortality From Window Strikes, Ann M. Sabo, Natasha D.G. Hagemeyer, Ally S. Lahey, Eric L. Walters

Biological Sciences Faculty Publications

Up to a billion birds die per year in North America as a result of striking windows. Both transparent and reflective glass panes are a cause for concern, misleading birds by either acting as invisible, impenetrable barriers to desired resources, or reflecting those resources over a large surface area. A high number of window strikes occur during migration, but little is known about the factors of susceptibility, or whether particular avian taxa are more vulnerable than others. We report on a study of window strikes and mist-netting data at the Virginia Zoological Park (Norfolk, Virginia, USA), conducted in the autumn …
