Evaluating Recruitment Of American Eel, Anguilla Rostrata, In The Potomac River (Spring 2014), Troy D. Tuckey, Mary C. Fabrizio

Reports

The Atlantic States Marine Fisheries Commission (ASMFC) adopted the Interstate Fishery Management Plan (FMP) for the American Eel in November 1999. The FMP focuses on increasing coastal states’ efforts to collect American Eel data through both fishery‐dependent and fishery‐independent studies. Consequently, member jurisdictions agreed to implement an annual survey for young‐of‐year (YOY) American eels. The survey is intended to “…characterize trends in annual recruitment of the YOY eels over time [to produce a] qualitative appraisal of the annual recruitment of American Eel to the U.S. Atlantic Coast” (ASMFC 2000). The development of these surveys began in 2000 with full implementation …

Annual Report - 2013 Data Collection And Analysis In Support Of Single And Multispecies Stock Assessments In Chesapeake Bay: The Chesapeake Bay Multispecies Monitoring And Assessment Program, Christopher F. Bonzek, James Gartland, Debra J. Gauthier, Robert J. Latour

Reports

Historically, fisheries management has been based on the results of single-species stock assessment models that focus on the interplay between exploitation level and sustainability. There currently exists a suite of standard and accepted analytical frameworks (e.g., virtual population analysis (VPA), biomass dynamic production modeling, delay difference models, etc.) for assessing the stocks, projecting future stock size, evaluating recovery schedules and rebuilding strategies for overfished stocks, setting allowable catches, and estimating fishing mortality or exploitation rates. A variety of methods also exist to integrate the biological system and the fisheries resource system, thereby enabling the evaluation of alternative management strategies on …

Monitoring Relative Abundance Of American Shad In Virginia Rivers 2013 Annual Report, Eric J. Hilton, Robert Latour, 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 …

Virginia Shellfish Aquaculture Situation And Outlook Report : Results Of The 2013 Virginia Shellfish Aquaculture Crop Reporting Survey, Karen Hudson, Thomas J. Murrary

Reports

The shellfish aquaculture industry in Virginia continues to grow, adding significant value to the state’s seafood marketplace. Today, watermen continue to harvest both hard clams and oysters from the state’s public resources, albeit at diminished rates. At the same time, Virginia’s watermen-farmers are providing growing quantities of additional quality shellfish to consumers. In recent years, folliowing the lead of the hard clam industry, a significant transition to intensive aquaculture of native oysters is underway. The once-extensive oyster planting utilizing wild seed has contracted primarily as a result of endemic oyster diseases and increasing wildlife predation of seed oysters. In its …

Bonzek, James Gartland, Debra J. Gauthier, Robert J. Latour

Reports

Concerns regarding the status of fishery-independent data collection from continental shelf waters between Cape Hatteras, North Carolina and the U.S. / Canadian border led the Atlantic States Marine Fisheries Commission’s (ASMFC) Management and Science Committee (MSC) to draft a resolution in 1997 calling for the formation of the Northeast Area Monitoring and Assessment Program (NEAMAP) (ASMFC 2002). NEAMAP is a cooperative state-federal program modeled after the Southeast Area Monitoring and Assessment Program (SEAMAP), which has been coordinating fishery-independent data collection south of Cape Hatteras since the mid1980s (Rester 2001). The four main goals of this new program directly address the …

American Shad Habitat Plan For The Commonwealth Of Virginia, Eric J. Hilton, Joe Cimino, Alan Weaver

Reports

In Virginia, American shad are found in the Chesapeake Bay and its major tributaries, including the Potomac, Rappahannock, York, and James rivers, as well as smaller tributaries and other coastal habitats (e.g., along the Delmarva peninsula) (Fig. 1). Additionally, American shad are found in certain rivers in Virginia that drain to North Carolina (Desfosse et al., 1994). Here we focus on the major western tributaries of the Chesapeake Bay as these areas have come to define the primary stocks in Virginia waters (the James, York, and Rappahannock stocks). Although certain spawning/rearing reaches are known for American shad for individual rivers …

Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay : Annual Progress Report : January 2013-December 2013, Mary C. Fabrizio, Troy D. Tuckey, Christopher D. Davis

Reports

The 2013 Striped Bass juvenile abundance index was 10.94 and was significantly higher than the historic average of 7.04. Abundance indices from individual rivers varied compared with their respective historic averages, and significantly higher recruitment was observed in the York River (particularly the Mattaponi River). Average recruitment occurred in the other rivers. Increased catches of young‐of‐the‐year Striped Bass at upriver and downriver auxiliary sites suggest an expansion of Striped Bass nursery grounds in 2013. The evident increase in occurrence of young‐of‐the‐year Striped Bass throughout the tidal tributaries in Virginia further supports the observation of an above‐average recruitment year in 2013. …
