Evaluation Of Striped Bass Stocks In Virginia, Monitoring And Tagging Studies, 2005-2009 Annual Report, 1 September 2008 - 31 August 2009, Philip W. Sadler, Matthew W. Smith, John M. Hoenig, Robert E. Harris, Lydia M. Goins, Rebecca J. Wilk
Evaluation Of Striped Bass Stocks In Virginia, Monitoring And Tagging Studies, 2005-2009 Annual Report, 1 September 2008 - 31 August 2009, Philip W. Sadler, Matthew W. Smith, John M. Hoenig, Robert E. Harris, Lydia M. Goins, Rebecca J. Wilk
Reports
This report presents the results of striped bass (Morone saxatilis) tagging and monitoring activities in Virginia during the period 1 September 2008 through 31 August 2009. It includes an assessment of the biological characteristics of striped bass taken from the 2009 spring spawning run, estimates of annual survival and fishing mortality based on annual spring tagging, and the results of the study that documents the prevalence of mycobacterial infections of striped bass in Chesapeake Bay. The information contained in this report is required by the Atlantic States Marine Fisheries Commission and is used to implement a coordinated management plan for …
Migration Dynamics, Within-Estuary Behaviors And Cardiorespiratory Responses Of Summer Flounder To Selected Estuarine Conditions, Karen M. Capossela
Migration Dynamics, Within-Estuary Behaviors And Cardiorespiratory Responses Of Summer Flounder To Selected Estuarine Conditions, Karen M. Capossela
Dissertations, Theses, and Masters Projects
A comprehensive understanding of migration dynamics, within-estuary behaviors and physiological tolerances of fish is needed to assess and predict future responses of fish to environmental disturbance and to protect habitat necessary for growth and survival. This study adds to current knowledge of summer flounder (Paralichthys dentatus) responses to environmental conditions by (1) examining migration and within-estuarine behaviors of adult summer flounder and (2) establishing summer flounder metabolic requirements and cardiorespiratory responses to variations in hypoxia and temperature. To elucidate use of a southern mid-Atlantic Bight estuary by adult summer flounder, the movements of 45 fish were monitored using acoustic telemetry …
Observations Of Distribution, Size, And Sex Ratio Of Mature Blue Crabs, Callinectes Sapidus, From A Chesapeake Bay Tributary In Relation To Oyster Habitat And Environmental Factors, Jm Harding, R Mann
Observations Of Distribution, Size, And Sex Ratio Of Mature Blue Crabs, Callinectes Sapidus, From A Chesapeake Bay Tributary In Relation To Oyster Habitat And Environmental Factors, Jm Harding, R Mann
VIMS Articles
Blue crabs Callinectes sapidus (Rathbun, 1896) > 100 mm carapace width were sampled from a constructed oyster reef (1996 and 1997), a sand bar (1997) and a natural oyster bar (1997) in the Piankatank River, Chesapeake Bay, USA to describe habitat use, sex ratios, and demographics across a gradient of habitat types. Patterns of blue crab catch-per-unit-effort (CPUE), and demographics were similar on the oyster reef in 1996 and 1997. Average annual CPUE on the reef was 6-8 crabs pot(-1) with maximum CPUE of 15 crabs pot(-1). Daylength and water temperature significantly affected reef CPUE with more crabs observed in late …
Bycatch Reduction Device Conserves Diamondback Terrapin Without Affecting Catch Of Blue Crab, Megan A. Rook, Rn Lipcius, Bret M. Bronner, Randolph Chambers
Bycatch Reduction Device Conserves Diamondback Terrapin Without Affecting Catch Of Blue Crab, Megan A. Rook, Rn Lipcius, Bret M. Bronner, Randolph Chambers
VIMS Articles
Bycatch mortality of non-target species in fisheries is a major threat to the conservation and restoration of marine and estuarine species. Attempts to reduce bycatch by fitting fishing gear with excluder devices have typically been met with resistance due to reductions in catch of target species. We examined the possibility that conservation and fishery goals could be met simultaneously. In lower Chesapeake Bay, we tested a mechanism for reducing bycatch of diamondback terrapin Malaclemys terrapin in blue-crab traps without affecting crab catch. Over 23 sampling dates during summer 2008, we compared terrapin captures at 2 shallow-water sites typical of recreational …
Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay, January 2009-December 2009 : Annual Progress Report, Leonard S. Machut, Mary C. Fabrizio
Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay, January 2009-December 2009 : Annual Progress Report, Leonard S. Machut, Mary C. Fabrizio
Reports
The 2009 striped bass juvenile abundance index is 8.42 and is not significantly different from the historic average of 7.54. Additional methods of calculating the regional index support this conclusion. Catches in the York River were nearly identical to its historic average. Although the James River catches were higher and the Rappahannock River catches were lower than historic averages, they were not significantly so. Striped bass catches at auxiliary stations provide greater spatial coverage of the nursery grounds and suggest that juvenile striped bass were broadly distributed throughout the sampling area in 2009.
Habitat Utilization And Dive Characterization Of Blue Marlin (Makaira Nigricans) And White Marlin (Kajikia Albida) In The Western Atlantic Ocean, Daniel J. Dutton
Habitat Utilization And Dive Characterization Of Blue Marlin (Makaira Nigricans) And White Marlin (Kajikia Albida) In The Western Atlantic Ocean, Daniel J. Dutton
Dissertations, Theses, and Masters Projects
Blue marlin Makaira nigricans and white marlin Kajikia albida (formerly Tetrapturus albidus) are overfished in the Atlantic Ocean, with the vast majority of fishing mortality resulting from the pelagic longline fishery that targets tunas (Thunnus spp.) and swordfish Xiphias gladius. Time series of catch-per-unit-effort (CPUE) data have been fundamental to assessments of blue marlin and white marlin stocks, but these time series have been affected by a shift over time in pelagic longline fishing practices from shallow to deeper sets. One method for adjusting CPUE data for changes in fishing practices is a habitat-based standardization that modifies fishing effort in …
Virginia Game Fish Tagging Program Annual Report 2009, John A. Lucy, Lewis Gillingham
Virginia Game Fish Tagging Program Annual Report 2009, John A. Lucy, Lewis Gillingham
Reports
Through 2009, the Virginia Game Fish Tagging Program has maintained a 15-year database for tagged and recaptured fish. The program is a cooperative project of the Virginia Saltwater Fishing Tournament (under the Virginia Marine Resources Commission/VMRC) and the Virginia Institute of Marine Science (VIMS) of the College of William and Mary (under VIMS Sea Grant Marine Extension Program).
