Estimating Relative Abundance Of Young-Of-The-Year American Eel, Anguilla Rostrata, In The Virginia Tributaries Of Chesapeake Bay, Spring 2018, 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. 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% …

A Brief Guide To Striped Bass Ecology & Management In Chesapeake Bay, Mary C. Fabrizio, Troy D. Tuckey, Susanna Musick

Reports

Chesapeake Bay striped bass support important recreational fisheries along the US Atlantic coast; in the late 1970s, the population of striped bass collapsed as a result of overfishing and poor water quality in rivers used for spawning and rear-ing of young. Informed by stock assessments, strict management regulations were enacted in the mid-1980s and early 1990s; these highly effective regulations resulted in the recovery of the population in 1995. A key to the successful recov-ery of the Atlantic coast striped bass was the wide range of ages of spawning females and the associated differences in spawning behavior among ages. Age …

Assessment Of Critical Habitats For Recovering The Chesapeake Bay Atlantic Sturgeon Distinct Population Segment, Bob Greenlee, David H. Secor, Greg C. Garman, Matthew Balazak, Eric J. Hilton, Matthew T. Fisher

Reports

The states of Virginia and Maryland along with Virginia Commonwealth University (VCU), Virginia Institute of Marine Science (VIMS) and University of Maryland Center for Environmental Science (UMCES) partnered to assess critical habitat for recovering the Chesapeake Bay Atlantic sturgeon (Acipenser oxyrinchus oxyrinchus) distinct population segment. The primary objectives were to assess reproductive habitat in the James River, nursery habitat in the James and York Rivers and the degree of dependence of those populations to habitat in the Chesapeake Bay.

Climate Change Impacts In Virginia: Status Of Natural Resource Data Records As Tools To Assess Continuing Trends, Tamia Rudnicky, Marcia Berman, Roger L. Mann, Carl Hershner

Reports

As scientists we pose the hypothesis that climate change over the past decades has left a signal in natural resource status and productivity in Virginia. This signal exists subsumed in a variety of data from crop and forestry production, to fishery landings, to spatial distribution of numerous plant and animal species of interest. Description of these signals in concert with known changes in climate descriptors (temperature, rainfall and more) provide a basis for hind-casting possible cause and effect relationships. If such relationships exist, and we hypothesize that they do, then projections of climate descriptors (temperature, rainfall and more) provide the …

Monitoring Relative Abundance Of American Shad In Virginia Rivers 2006 Annual Report, John E. Olney, Kristen Delano Walter

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 …

Estimating Relative Abundance Of Young Of The Year American Eel, Anguilla Rostrata, In The Virginia Tributaries Of Chesapeake Bay, Patrick J. Greer

Reports

The Atlantic States Marine Fisheries Commission (ASMFC) adopted the Interstate Fishery Management Plan for American Eel (FMP) in November 1999. The Plan focuses on increasing the states’ efforts to collect data on the resource and the fishery it supports through fishery dependent and independent studies. To this end, member jurisdictions (including Virginia) agreed to implement an annual abundance survey of young-of-year American eel (YOY). The survey is intended to “...characterize trends in annual recruitment of the young of the year eel over time [to produce a] qualitative appraisal of the annual recruitment of American eel to the U.S. Atlantic coast …
