Juvenile Fish And Blue Crab Stock Assessment Program Bottom Trawl Survey Annual Data Summary Report Volume 1999, Wendy A. Lowery, M. Todd Mathes, Patrick J. Geer

Reports

This report summarizes data collected by the Virginia Institute of Marine Science (VIMS) monthly trawl survey cruises for January to December 1999. The trawl survey is a long-term, broad scope monitoring program. Its primary goal is to monitor juvenile abundance for marine and estuarine finfish and invertebrates. A major objective is to provide annual indices of juvenile abundance for recreationally, commercially, and ecologically important species of sufficient accuracy and precision for both immediate resource management needs and long-term understanding of environmental influences on fishery resources. A second important product of this effort is the documentation and monitoring of habitat utilization …

Results Of Commercial Sea Scallop Survey In The Hudson Canyon South Closed Area, William D. Dupaul, David B. Rudders, Paul J. Rago

Reports

This report presents the results of the commercial survey of the Hudson Canyon Closed Area. The survey was conducted aboard the FN Alice Amanda from June 8-15, 2000. A systematic grid design was utilized with survey stations located approximately 5 nm apart (Figure l ). Survey stations were located both inside and outside the boundaries of the closed area. Additional stations were added along the western, northern ru1d southern boundaries in an attempt to resolve the boundary effects on sea scallop abundance and size distribution. Survey tows were l O minutes in duration at a speed of 4.5-5.0 kts. The …

Preliminary Results Of Commercial Sea Scallop Survey In The Hudson Canyon South Closed Area June 2000, William D. Dupaul, David Rudders, Paul J. Rago

Reports

This report presents the preliminary results of the commercial survey of the Hudson Canyon Closed Area. The survey was conducted aboard the FN Alice Amanda from June 8-15, 2000. A systematic grid design was utilized with survey stations located approximately 5 nm apart (Figure 1). Survey stations were located both inside and outside the boundaries of the closed area. Additional stations were added along the western, northern and southern boundaries in an attempt to resolve the boundary effects on sea scallop abundance and size distribution. Survey tows were 10 minutes in duration at a speed of 4.5-5.0 kts. The sampling …

Monitoring Relative Abundance Of American Shad In Virginia's Rivers Annual Report 1999, John E. Olney Sr., John M. Hoenig

Reports

A moratorium on the taking of American shad (Alosa sapidissima) in the Chesapeake Bay and its tributaries was established by the Virginia Marine Resources Commission (VMRC) beginning 1 January 1994. The prohibition applied to both recreational and commercial fishers. The moratorium was imposed at a time when commercial catch rates of American shad in Virginia's rivers were experiencing declines. Data from the commercial fishery were the best available for assessing the status of individual stocks. Catch-per-unit-effort (CPUE) data were compiled from logbooks that recorded landings by commercial fishermen using staked gill nets at various locations throughout the middle reaches of …

A Comparative Field Study Of Crassostrea Ariakensis And Crassostrea Virginica In Relation To Salinity In Virginia, Gustavo W. Calvo, Mark Luckenbach, Standish K. Allen Jr., Eugene M. Burreson

Reports

In accordance with the Rational Plan for Testing Application of Non-Native Oyster Species (VIMS 1996) we conducted a field experiment to examine survival, growth and disease susceptibility of Crassostrea ariakensis (=rivularis) in relation to salinity in Virginia. The performance of triploid C. ariakensis in comparison with that of diploid C. virginica, (n = 250, age = 2 years, mean shell height = 60- 64 mm) was evaluated at replicate sites within low, medium, and high salinity regimes (respectively, < 15‰, 15-25‰, > 25‰) in Chesapeake Bay and the Atlantic Coast. During the course of this study, from June 1998 to September 1999, there was …
