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 …
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 …
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, …
