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 …

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
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 …

Size Selectivity Of Crappie Angling, Leandro E. Miranda, Brian S. Dorr
Size Selectivity Of Crappie Angling, Leandro E. Miranda, Brian S. Dorr
Brian S Dorr
Abstract.—Over 6,000 black crappies Pomoxis nigromaculatus and white crappies P. annularis were tagged in five lakes and reservoirs to quantify size selectivity of angling. Total length of fish tagged ranged from 20.0 to 39.8 cm; fish caught by anglers ranged from 20.0 to 38.8 cm. Return rates were low at lengths near 20 cm, increased gradually to a peak between 26 and 32 cm, and decreased for longer fish. This pattern was consistent among the five lakes and reservoirs and did not differ between species. Observed size-selective exploitation resulted in the lopsided removal of intermediate age-classes, thereby simulating a reversed …
