Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay Annual Progress Report: 2022 - 2023, Jack R. Buchanan, Mary C. Fabrizio, Troy D. Tuckey

Reports

The 2022 juvenile Striped Bass abundance index was 7.95 and was not significantly different than the reference mean of 7.77 for the period 1980 to 2009. Abundance indices were average in the York and Rappahannock rivers and below average in the James River in 2022 compared with the river-specific reference means (1980-2009). Relatively low catches of young‐of‐the‐year Striped Bass from sites upriver and downriver of core nursery areas suggest juvenile Striped Bass largely remained within core nursery areas in 2022.

Indices of abundance were also calculated for three additional economically and recreationally important fishes in Virginia waters. Juvenile White Perch …

Estimating Relative Abundance Of Young-Of-Year American Eel, Anguilla Rostrata, In The Virginia Tributaries Of Chesapeake Bay (Spring 2022), Troy D. Tuckey, Daniel Royster, 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 calls for efforts to collect American Eel data through both fishery-dependent and fishery-independent studies in coastal states. Consequently, member jurisdictions agreed to implement an annual survey for young-of-year (YOY or glass) 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 …

Characterization Of Nursery Habitats Used By Black Sea Bass And Summer Flounder In Chesapeake Bay And The Coastal Lagoons, Mary C. Fabrizio, Troy D. Tuckey, Shannon C. Smith, Paige G. Ross, Richard A. Snyder, Harry V. Wang, Aaron J. Bever

Reports

Coastal habitats are increasingly impacted by intersecting and often competing human activities overlaid on habitat loss and degradation. These demands have prompted resource managers to implement marine spatial-planning strategies (Foley et al. 2010), but the effectiveness of this approach depends on the quality and resolution of the ecological information considered in delineating best uses of public natural resources. Many economically and ecologically important species such as summer flounder and black sea bass depend on inshore nursery habitats, yet habitat-specific utilization patterns lack the resolution needed to protect critical areas and inform ecological restoration strategies. To address these data gaps, we …

Extent Of Suitable Habitats For Juvenile Striped Bass: Dynamics And Implications For Recruitment In Chesapeake Bay, Rachel L. Dixon, Mary C. Fabrizio, Troy D. Tuckey, Aaron J. Bever

Reports

The production of striped bass Morone saxatilis in Chesapeake Bay supports recreational and commercial fisheries along the Atlantic coast of the United States, but factors that contribute to high abundances of juvenile life stages are not fully understood. In this study, we characterized and quantified suitable and optimal habitat conditions in the Chesapeake Bay for two age groups of juvenile striped bass in discrete portions of the Bay: young-of-the-year (age-0) fish in shoreline and nearshore habitats, and resident sub-adults (age-1 to -4) in the mainstem and Bay-wide. We coupled information from 24 years of monthly fisheries surveys with hindcasts from …

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). …

Seasonal And Annual Variation In The Extent Of Suitable Habitats For Forage Fishes In Chesapeake Bay, 2000-2016, Mary C. Fabrizio, Troy D. Tuckey, Aaron J. Bever, Michael L. Macwilliams

Reports

The sustained production of sufficient forage is critical to advancing ecosystem-based management in Chesapeake Bay. Yet factors that affect local abundances and habitat conditions necessary to support forage production remain largely unexplored. Here, we quantified suitable habitat in the Chesapeake Bay region for four key forage fishes: bay anchovy Anchoa mitchilli, juvenile spot Leiostomus xanthurus, juvenile weakfish Cynoscion regalis, and juvenile spotted hake Urophycis regia. We coupled information from 17 years of monthly fisheries surveys with hindcasts from a numerical model of dissolved oxygen (DO) conditions and a 3-D hydrodynamic model of the Bay that provided …
