Calibration Of Vims Research Vessel Catch Data To Ensure Continuity Of Recruitment Indices For The Chesapeake Bay Region, Mary C. Fabrizio, Troy D. Tuckey
Calibration Of Vims Research Vessel Catch Data To Ensure Continuity Of Recruitment Indices For The Chesapeake Bay Region, Mary C. Fabrizio, Troy D. Tuckey
Reports
The VIMS Juvenile Fish Trawl Survey, which has been in operation since 1955, has undergone considerable changes to the sampling gear, location of sampling sites, and the methodology used to select sampling sites. Recently, a new vessel, the R/V Tidewater, replaced the R/V Fish Hawk, which had been in service for 25 years. In addition to the change in vessel, a new net was used; this net design is more robust to deployment methods and performs more consistently under varying environmental conditions. Therefore, a calibration study was conducted whereby the two research vessels with different nets fished in the same …
Population Size And Survival Rates Of Blue Catfish In Chesapeake Bay Tributaries, Mary C. Fabrizio, Troy D. Tuckey, Robert J. Latour, Gary C. White, Alicia J. Norris, Mary Groves
Population Size And Survival Rates Of Blue Catfish In Chesapeake Bay Tributaries, Mary C. Fabrizio, Troy D. Tuckey, Robert J. Latour, Gary C. White, Alicia J. Norris, Mary Groves
Reports
This report comprises two studies conducted from 2012 to 2015 to estimate population size, survival rates, and movements of invasive blue catfish in Chesapeake Bay tributaries. The first study of population-size and survival was conducted in the James River, VA (Population Size and Survival Rates of Invasive Blue Catfish in Tidal Waters of the James River Subestuary). The second study on movement and survival of blue catfish was conducted in the Potomac River, the natural boundary between Maryland and Virginia (Movement Patterns and Survival Rate of Blue Catfish in a Non-Native Habitat Estimated with a Tagging Study). The Executive Summary …
Evaluation Of Striped Bass Stocks In Virginia: Monitoring And Tagging Studies, 2015-2019 : Progress Report 1 September 2015 - 31 August 2016, Philip W. Sadler, John M. Hoenig, Savannah Michaelsen, Lydia M. Goins, Robert E. Harris
Evaluation Of Striped Bass Stocks In Virginia: Monitoring And Tagging Studies, 2015-2019 : Progress Report 1 September 2015 - 31 August 2016, Philip W. Sadler, John M. Hoenig, Savannah Michaelsen, Lydia M. Goins, Robert E. Harris
Reports
This report presents the results of striped bass (Morone saxatilis) tagging and monitoring activities in Virginia during the period 1 September 2015 through 31 August 2016. It includes an assessment of the biological characteristics of striped bass taken from the 2016 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. Also included is an investigation on the potential use of close-kin analyses to determine the size of the spawning stock in the Rappahannock River. The …
Estimating Relative Juvenile Abundance Of Ecologically Important Finfish In The Virginia Portion Of Chesapeake Bay (1 June 2015 - 31 May 2016) : 2016 Annual Report, Troy D. Tuckey, Mary C. Fabrizio
Estimating Relative Juvenile Abundance Of Ecologically Important Finfish In The Virginia Portion Of Chesapeake Bay (1 June 2015 - 31 May 2016) : 2016 Annual Report, Troy D. Tuckey, Mary C. Fabrizio
Reports
The Trawl Survey provides crucial data to state, regional, and national fisheries management agencies, including the Virginia Marine Resources Commission (VMRC), the Atlantic States Marine Fisheries Commission (ASMFC), the Mid‐Atlantic Fisheries Management Council (MAFMC), and the National Marine Fisheries Service (NMFS). The MAFMC recognizes the juvenile trawl survey as one of the key predictors of Summer Flounder recruitment. Annual indices of juvenile abundance have been generated from trawl survey data for species of key recreational, ecological, and commercial importance in the Virginia portion of Chesapeake Bay. These include Spot, Atlantic Croaker, Weakfish, Summer Flounder, Black Sea Bass, Scup, Striped Bass, …

Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay : Annual Progress Report : 2015-2016, Christopher D. Davis, Mary C. Fabrizio, Troy D. Tuckey
Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay : Annual Progress Report : 2015-2016, Christopher D. Davis, Mary C. Fabrizio, Troy D. Tuckey
Reports
The 2015 Striped Bass juvenile abundance index was 12.00 and was not significantly greater than the historic average of 8.63. Compared with their respective historic averages abundance indices from individual rivers in 2015 varied, such that significantly higher recruitment was observed in the Rappahannock River and average recruitment was observed in the James and York rivers. Relatively higher catches of young‐of‐the‐year Striped Bass at upriver and downriver auxiliary sites suggest expansion of Striped Bass nursery grounds in 2015. Unlike Striped Bass in Virginia waters, juvenile White Perch abundance indices in 2015 were significantly greater than the historic average for this …
