Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay Annual Progress Report: 2019 - 2020, Jack R. Buchanan, Troy D. Tuckey, Mary C. Fabrizio May 2020

Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay Annual Progress Report: 2019 - 2020, Jack R. Buchanan, Troy D. Tuckey, Mary C. Fabrizio

Reports

The 2019 Striped Bass juvenile abundance index was 9.54 and was not significantly different than the reference mean of 7.77 from 1980-2009. Abundance indices in the James, York, and Rappahannock rivers in 2019 were average compared with their individual reference means (1980-2009). Relatively low catches of young‐of‐the‐year Striped Bass from sites upriver and downriver of core nursery areas suggest Striped Bass largely remained within core nursery areas in 2019. Juvenile White Perch abundance indices in 2019 were above historic averages in the James, York and Rappahannock river systems.

The Status Of Virginia’S Public Oyster Resource 2019, Melissa Southworth, Roger L. Mann Jan 2020

The Status Of Virginia’S Public Oyster Resource 2019, Melissa Southworth, Roger L. Mann

Reports

The Virginia Institute of Marine Science (VIMS) monitors recruitment of the Eastern oyster, Crassostrea virginica (Gmelin, 1791), annually from late spring through early fall, by deploying spatfall1 (settlement and recruitment of larval oysters to the post metamorphic form termed spat) collectors (shellstrings) at various sites in three Virginia western Chesapeake Bay tributaries. The survey provides an estimate of a particular area’s potential for receiving a "strike" or settlement (set) of oysters on the bottom and helps describe the timing of recruitment events in a given year. Information obtained from this monitoring effort provides an overview of long-term recruitment trends ...

Fuels Guide For Sagebrush And Pinyon-Juniper Treatments: 10 Years Post-Treatment, Samuel S. Wozniak, Eva K. Strand

Reports

Increased woody plant dominance and degraded understory vegetation are important issues on rangelands in the Intermountain West. Land managers implement woody plant reduction treatments of sagebrush (Artemisia spp.), juniper (Juniperus spp.), and pinyon pine (Pinus spp.) to increase understory diversity and cover, restore wildlife habitat, increase forage, improve ecosystem functions, and reduce or manipulate fuels to increase ecosystem resilience to fire and resistance to invasive annual grasses. Woody plant reduction treatments alter fuel orientation, continuity, and loading, and therefore have important implications for wildfire behavior, effects, and management. Currently, there is a lack of knowledge of the longer-term implications of ...

Evaluating Recruitment Of American Eel, Anguilla Rostrata, In The Potomac River (Spring 2019), 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 2016, Chesapeake Bay commercial landings of American Eel (728,717 lbs) were 78% of the U.S. landings (personal communication from the National Marine Fisheries Service, Fisheries Statistics Division). Since the 1980s, harvest along the U ...

Evaluating The Condition And Discard Mortality Of Monkfish, Lophius Americanus, Following Capture And Handling In The Sea Scallop Dredge Fishery, David Rudders, Sally Roman, Amelia Weissman, Ryan Knotek, John Mandelman, James Sulikowski

Reports

The incidental capture of nontarget organisms, known as bycatch, remains an unavoidable occurrence for all fisheries (Kirby and Ward, 2014). One of the most challenging issues facing fisheries management is the post-release mortality of these bycaught species due to its difficulty to predict and the variability among species and gear type (Benoit et al., 2010, 2013; Depestele et al., 2014), which makes it inherently difficult to conduct proper stock assessments. Since there have been few studies conducted on post-release mortality across species, fisheries managers typically assign conservative estimates of mortality which limits total allowable catch and may negatively impact the ...

A Study To Assess The Effect Of Tow Duration And Estimate Dredge Efficiency For The Vims Sea Scallop Dredge Survey : Final Report, David Rudders, Sally Roman, Arthur Trembanis, Danielle Ferraro

Reports

For the sea scallop, Placopecten magellanicus, the concepts of space and time have emerged as the basis of an effective management tool. The strategy of closing or limiting activities in certain areas for specific lengths of time has gained support as a method to conserve and enhance the sea scallop resource. In the last decade, rotational area management has provided a mechanism to protect juvenile scallops from fishing mortality by closing areas based upon scallop abundance and age distribution. Approximately half of the sea scallop industry’s current annual landings come from areas under this rotational harvest strategy. While this ...

Fisher, David Bushek, Daphne Munroe, Eleanor A. Bochenek, Emily Mcgurk, Sarah Borsetti

Reports

A disease epizootic has developed that threatens one of the most valuable fisheries in the US. The U.S. sea scallop (Placopecten magellanicus) fishery landed $512 million worth of scallop meats in 2017 (NMFS, 2018). This fishery is based on landings of scallop adductor muscles only, with the remainder of the scallop discarded at sea (NEFSC, 2018). During the spring of 2015 both industry and scientific assessment crews noted unprecedented numbers of a parasitic nematode in the adductor muscle of captured scallops (Figure 1). The presence of the parasite in the adductor muscle is expressed through macroscopic lesions, or cysts ...

Annual Report - 2018 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 ...

Air Quality Modelling For Ireland, Aoife Donnelly, Bruce Misstear, Brian Broderick

Reports

Air pollution is the primary environmental cause of premature death in the EU (European Commission, 2013) and the most problematic pollutants across Europe have consistently been oxides of nitrogen (e.g. nitrogen dioxide (NO2)), particulate matter (e.g. PM10, PM2.5) and ozone (O3). While measurements form an important aspect of air quality assessment, on their own they are unlikely to be sufficient to provide an accurate spatial and temporal description of the pollutant concentrations for exposure assessment and moreover they cannot provide information regarding future air quality.

Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay. Annual Progress Report: 2018-2019, Brian K. Gallagher, Mary C. Fabrizio, Troy D. Tuckey

Reports

The 2018 Striped Bass juvenile abundance index was 10.72 and was not significantly different than the reference mean of 7.77 from 1980-2009. Abundance indices in the James and York river systems in 2018 were average compared to their individual reference means (1980-2009), whereas abundance was above average in the Rappahannock River. Relatively high catches of young‐of‐the‐year Striped Bass at downriver sites in 2018 suggested Striped Bass were displaced downstream of their typical core nursery areas, likely due to high volumes of freshwater discharge and low salinities before and during the sampling period.

One Fish, Two Fish, Red Fish, Whose Fish? Subjects: Life Science, Environmental Science, Marine / Ocean Science, Shelby White

Reports

This activity invites students to assume the role of various stakeholders in fisheries management and actively discuss the influence of economics, ecology and human interactions in decision-making.

Students will demonstrate their argument for/against a certain regulation by participating as a specific stakeholder (i.e. commercial fisher, recreational fisher, scientists/researcher, environmental group, management agency, and citizen). Students will recognize that stakeholders tend to advocate based on their individual needs, often making it difficult for proposed policies to satisfy the needs of all stakeholders and achieve sustainability goals.
