Georges Bank Yellowtail Flounder Estimates From Vims Industry-Based Scallop Dredge Surveys Of Closed Area Ii And Surrounds, Sally Roman, David Rudders
Georges Bank Yellowtail Flounder Estimates From Vims Industry-Based Scallop Dredge Surveys Of Closed Area Ii And Surrounds, Sally Roman, David Rudders
Reports
This document is the final report submitted to the New England Fishery Management Council (NEFMC) for the Georges Bank Yellowtail Flounder Estimates from VIMS Industry-Based Scallop Dredge Surveys of Closed Area II and Surrounds project. The NEFMC funded this project in April 2019, with an objective of synthesizing existing VIMS dredge survey data with respect to the Georges Bank stock of yellowtail flounder (Limanda ferruginea). Analysis consisted of an examination of existing catch data from VIMS dredge surveys of Georges Bank Closed Area II and surrounds from 2005 to 2019.
Results For The 2019 Vims Industry Cooperative Surveys Of The Mid-Atlantic, Nantucket Lightship Closed Area, Closed Area I, And Closed Area Ii Resource Areas, David Rudders, Sally Roman, Erin Mohr, Kaitlyn Clark
Results For The 2019 Vims Industry Cooperative Surveys Of The Mid-Atlantic, Nantucket Lightship Closed Area, Closed Area I, And Closed Area Ii Resource Areas, David Rudders, Sally Roman, Erin Mohr, Kaitlyn Clark
Reports
The Virginia Institute of Marine Science (VIMS) conducted high resolution sea scallop dredge surveys of the entire Mid-Atlantic (MAB), the Nantucket Lightship (NLCA), Closed Area I (CAI), and Closed Area II (CAII) during May–July 2019. These surveys were funded by the Sea Scallop Research Set- Aside Program (RSA). Exploitable biomass for each survey is shown in Table 1 for each spatially explicit SAMS Area (Scallop Area Management Simulator). SAMS Areas represent management relevant spatial subunits of the resource and explicitly account for differences in recruitment, vital rates, and fishing effort in the forward projection of survey information. Maps of SAMS …

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 …
Age Structure And Growth Rate In The Sea Scallop Placopecten Magellanicus, Roger Mann, David Rudders
Age Structure And Growth Rate In The Sea Scallop Placopecten Magellanicus, Roger Mann, David Rudders
Reports
The overall project objective is to describe age structure and growth of scallops from the Georges Bank and Mid-Atlantic regions. There are three component objectives; (1) age structure and growth during the 1977- 1999 period using archived material stored at NEFSC Woods Hole; (2) age structure and growth of scallops collected over the latitudinal and bathymetric range of the US commercial fishery in 2012 and 2013 (material archived at VIMS from RSA studies); and (3) age structure and growth of scallops collected in 2017 assessment surveys by co-PI Rudders.

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 represents …
An Investigation Into The Scallop Parasite Outbreak On The Mid-Atlantic Shelf: Transmission Pathways, Spatio-Temporal Variation Of Infection And Consequences To Marketability : Final Report, David Rudders, Sally Roman, Robert A.

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. These …

Virginia Game Fish Tagging Program Annual Report 2018, Susanna Musick, Lewis Gillingham
Reports
Through 2018, the Virginia Game Fish Tagging Program (VGFTP) has maintained a 23-year database of records for tagged and recaptured fish. The program is a cooperative project of the Virginia Saltwater Fishing Tournament (VSFT) under the Virginia Marine Resources Commission-(VMRC) and the Virginia Institute of Marine Science (VIMS) of the College of William and Mary (under the VIMS Marine Advisory Program).
