Evaluation of striped bass stocks in Virginia, monitoring and tagging studies, 1999-2003 Annual report, 1 September 1999 - 31 October 2000

To document continued compliance with Federal law, the Anadromous Fishes Program of the Virginia Institute of Marine Science (VIMS) has monitored the size and age composition, sex ratio and maturity schedules of the spawning striped bass stock in the Rappahannock River since December 1981 utilizing commercial pound nets and, since 1991, variable-mesh experimental gill nets. Spawning stock assessment was expanded to include the James River in 1994 utilizing 11 commercial fyke nets and variable-mesh experimental gill nets. The use of fyke nets was discontinued after 1997. In conjunction with the monitoring studies, tagging programs have been conducted in the James and Rappahannock rivers since 1987 . These studies were established to document the migration and relative contribution of these Chesapeake Bay stocks to the coastal population and to provide a means to estimate inter-year survival rates (S). With the reestablishment of fall recreational fisheries in 1993, the tagging studies were expanded to include the York River and western Chesapeake Bay to provide a direct estimation of the resultant fishing mortality (F). This document reports the results of our tagging and monitoring activities during the period 1 September 1999 through 31 October 2000. It includes an assessment of the biological characteristics of striped bass taken from the 2000 spring spawning run, estimates of annual survival based on annual spring tagging, and the results of the fall 1999 directed mortality study that is cooperative with the Maryland Department of Natural Resources. 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 striped bass in Virginia, and along the eastern seaboard

Evaluation of Striped Bass Stocks in Virginia: Monitoring Studies, 1993-1998 Completion Report 1 September 1997 - 31 October 1998

To document continued compliance with Federal law, the Virginia Institute of Marine Science (VIMS) Anadromous Program (AP) has monitored the size and age composition, sex ratio and maturity schedules of the spawning striped bass stock in the Rappahannock River since December 1981 utilizing commercial pound nets and, since 1991, variable-mesh experimental anchored gill nets. Spawning stock assessment was expanded to include the James River in 1994 utilizing extant commercial fyke nets and variable-mesh experimental gill nets. The use of fyke nets was discontinued after 1997. Tagging programs have been conducted in the James and Rappahannock rivers since 1987 in conjunction with the monitoring studies. These studies were established to document the migration and relative contribution of these Chesapeake Bay stocks to the coastal population and to provide a mean to estimate inter-year survival rates (S). The tagging studies were expanded to the York River and western Chesapeake Bay to provide a direct estimation of the resultant fishing mortality (F) with the re-establishment of fall recreational fisheries in 1993 . Because of low stock levels of striped bass in the recent past, and the variable nature of their population dynamics, Chesapeake Bay stocks may or may not be contributing their full potential to the coastal population which supports the fisheries north of Chesapeake Bay. Therefore, the information contained in this report is important to the development and implementation of a coordinated management plan for striped bass in Virginia, and along the eastern seaboard
