Scallop Mark-Recapture To Estimate Density Dependent Natural Mortality And Growth : Final Report, David Rudders, John Hoenig, Sally Roman
Scallop Mark-Recapture To Estimate Density Dependent Natural Mortality And Growth : Final Report, David Rudders, John Hoenig, Sally Roman
Reports
Natural mortality, growth and movement are fundamental processes critical to understanding and describing population dynamics. These population characteristics not only inform and influence stock assessment models, but are also highly relevant with respect to the design and implementation of management strategies to meet fishery objectives. For many species, including sea scallops, these population parameters are difficult to measure due to the nature of the habitats inhabited and as a result, minimal information is often available. In many cases, what estimates do exist are highly uncertain as a result of both observation and process error. The uncertainty of these parameters is …

An Assessment Of Sea Scallop Abundance And Distribution In Georges Bank Closed Area Ii And The Southern Extension Closure: Final Report, David Rudders, Sally Roman
An Assessment Of Sea Scallop Abundance And Distribution In Georges Bank Closed Area Ii And The Southern Extension Closure: Final Report, David Rudders, Sally Roman
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 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 a …

Virginia Game Fish Tagging Program Annual Report 2017, Susanna Musick, Lewis Gillingham
Virginia Game Fish Tagging Program Annual Report 2017, Susanna Musick, Lewis Gillingham
Reports
Through 2017, the Virginia Game Fish Tagging Program (VGFTP) has maintained a 22-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).

Virginia Seafood Sustainability, Robert A. Fisher
Virginia Seafood Sustainability, Robert A. Fisher
Reports
Virginia’s commercial fisheries operate sustainably under a suite of management tools based upon information received from marine scientists and fishery managers who regularly conduct biological sampling of fish while tracking commercial landings and other gathering of required information. Analyses of fishing effort and overall stock conditions, as well as formulas designed to calculate threshold limits for maintaining sustainable stocks are regularly performed. Restrictions on seasons, size, days at sea, and gear are imposed as needed to achieve management supporting long-term biological sustainability.
