Monitoring The Abundance Of American Shad And River Herring In Virginia's Rivers - 2019 Annual Report, Eric J. Hilton, Robert Latour, Patrick E. Mcgrath, Brian Watkins, Ashleigh Magee

Reports

This report describes the results of the twenty-second 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 2019, evaluating hatchery programs, and contributing to coast-wide assessments (ASMFC 2007). We also report on two fishery-independent monitoring programs using anchor gillnets in the Rappahannock River (year 2) and the Chickahominy River (year 5; a major tributary of the James River), to determine relative abundance and stock structure for the adult spawning run of river herring …

Estimating Relative Abundance Of Young-Of-The-Year American Eel, Anguilla Rostrata, In The Virginia Tributaries Of Chesapeake Bay, Spring 2016, Mary C. Fabrizio, Troy D. Tuckey

Reports

American Eel (Anguilla rostrata) is a valuable commercial species along the Atlantic coast of North America from New Brunswick to Florida. In the U.S., harvests have declined, with similar patterns occurring in the Canadian Maritime Provinces (Meister and Flagg 1997). An average of 62% of the annual landings of U.S. commercial harvest since 1993 have come from the Chesapeake Bay (personal communication from the National Marine Fisheries Service, Fisheries Statistics Division, 9 February 2015). In 2013, Virginia commercial landings were approximately 100,298 lbs; since mandatory reporting began in 1993, average annual landings in Virginia have been 193,200 lbs or 19% …

Reports

This report comprises two studies conducted from 2012 to 2015 to estimate population size, survival rates, and movements of invasive blue catfish in Chesapeake Bay tributaries. The first study of population-size and survival was conducted in the James River, VA (Population Size and Survival Rates of Invasive Blue Catfish in Tidal Waters of the James River Subestuary). The second study on movement and survival of blue catfish was conducted in the Potomac River, the natural boundary between Maryland and Virginia (Movement Patterns and Survival Rate of Blue Catfish in a Non-Native Habitat Estimated with a Tagging Study).

Evaluating Recruitment Of American Eel, Anguilla Rostrata, In The Potomac River (Spring 2016), 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 2012, Chesapeake Bay commercial landings of American Eel (771,536 lbs) were 72% of the U.S. landings (personal communication from the National Marine Fisheries Service, Fisheries Statistics Division). Since the 1980s, harvest along the U.S. Atlantic Coast …

Virginia Coastal And Ocean Resource Issues, Virginia Institute Of Marine Science

Reports

Fisheries, aquaculture and marine recreation in Chesapeake Bay and the coastal ocean are important economic engines adding greatly to the economy of the Commonwealth of Virginia. Virginia’s commercial harvest ranks 3rd largest and 7th in total value nationwide. Research at the Virginia Institute of Marine Science (VIMS) shows that Virginia’s water-dependent resource-based industries, including commercial and recreational fisheries, shellfish aquaculture and recreational boating, annually generate $2.53 billion in sales and approximately $1.25–$1.5 billion in income, supporting over 20,000 jobs. . . .

Oyster Reef Habitat Restoration : A Synopsis And Synthesis Of Approaches; Proceedings From The Symposium, Williamsburg, Virginia, April 1995, Mark Luckenbach, Roger L. Mann, James A. Wesson

Reports

This volume has its origin in a symposium held in Williamsburg, VA in April 1995, though most of the chapters have been significantly revised in the interim. The primary purpose of the symposium was to bring together state fisheries managers involved in fisheries-directed oyster enhancement and research scientists to refine approaches for enhancing oyster populations and to better develop the rationale for restoring reef habitats. We could hardly have anticipated the degree to which this been successful. In the interim between the symposium and the publication of this volume the notion that oyster reefs are valuable habitats, both for oysters …

Chesapeake Bay Bibliography - Volume V. Virginia And Maryland Waters, Marilyn Neff Loesch

Reports

The Chesapeake Bay Bibliography was initiated by the Virginia Institute of Marine Science in response to growing resource management problems of the Chesapeake Bay and its tributaries. With these problems came the realization that planning and management of such a great natural resource is an overwhelming task requiring the best available information. This bibliography, therefore, was undertaken to document existing sources of information, to help identify research and data gathering needs, and to develop a comprehensive research and information services programs for individuals interested in research on, and management of the natural resources of the Chesapeake Bay region.

Estimate Of The Total Weight Of Kepone In The Major Components Of The Molluscan Fauna Of The James River, Virginia, Dexter S. Haven, Reinaldo Morales-Alamo

Reports

Contamination of the James River in Virgin ia with the pesticide Kepone has resulted in its accumulation in the tissues of the fauna inhabiting the river. Most of the Kepone available to the biota in the river is associated with sediment s (Schneider and Dawson, 1978) and Haven and Morales-Alamo (1979) have shown that oysters and other bivalve molluscs accumulate Kepone in their tissues when exposed to the pesticide associated with sediments in suspension. It is of interest to compare the quantities of Kepone bound in James River sediments with the quantities bound in the molluscan fauna of the river.

This work results from the confluence of two programs of investigation and, naturally, from a common interest in ecological problems. The Institute of Forrestry and Plant Biology had utilized, besides other methods, the analysis of principle components of correlation matrices for the study of vegetation and have at their disposal adequate programs for the treatment of a great volume of data. For its part, the Institute of Fishery Investigations is interested in very similar problems of classification, standardization and calculation, and has collected a large quantity of data on the cell density of different species in the plankton and environmental …

Check List Of The Marine Invertebrates Of Virginia, Marvin L. Wass

Reports

This list is the third revision of a preliminary list compiled by Dr. Willis G. Hewatt in 1959. This latest revision has been shortened by the deletion of most oceanic species. Conversely, a number of estuarine species have been added through further work. Those species known from the published work of the Chesapeake Biological Laboratory, Solomons Island, Maryland, have been included.

For several groups the list should be quite complete; for others, such as the amphipods, of which there are 21 unidentified species in the VIMS collection, much taxonomic work remains. Since many species have been identified only by the …
