Anadromous Fishes of the Potomac Estuary

Anadromous fishes have been and continue to be important members of the ichthyofauna within the tidal waters of the Potomac River and other tributaries of Chesapeake Bay in the ecological, commercial, recreational and aesthetic sense. Attributes of the Potomac River basin and its waters have been described in several earlier presentations and shall be cited herein only as they apply to anadromous fishes.https://scholarworks.wm.edu/vimsbooks/1136/thumbnail.jp

Feasibility of increasing striped bass populations by stocking of underutilized nursery grounds : annual progress report 1971-1972

Numerous estuaries in the lower Chesapeake Bay region and coastal Virginia possess physical, chemical and biological properties favorable· to their use as nursery grounds for striped bass. Many of them, however, are not so utilized because of the absence of associated spawning grounds. This project was designed to investigate the feasibility of stocking such underutilized nursery grounds as a management device, while monitoring population parameters such as age composition, mortality rates and relative abundance of year classes

Feasibility of increasing striped bass populations by stocking of underutilized nursery grounds : Completion report 1970-1973

The research program at VIMS concerning striped bass in the Viiginia tributaries of Chesapeake Bay is summarized in this report. Results herein presented represent a completion report relative to the contract with the Bureau of Sport Fisheries and Wildlife; but they are only a progress report of the assessment and management program for striped bass in Virginia waters

Thermal plume entrainment of ichthyoplankton at the VEPCO Surry Nuclear Power Station : progress report, October 1975

Plume entrainment studies at Vepco Nuclear Power Plant located near Surry, Virginia were initiated in August, 1975 by the Ichthyology department of Virginia Institute of Marine Science. The program was undertaken to define the amount and kinds of fish eggs and larvae that are. present in the Cobham Bay area of the James River and become entrained by the heated effluent

A Report to the Oyster Industry of Virginia on the Biology and Management of the Cownose Ray (Rhinoptera bonasus, Mitchill) in Lower Chesapeake Bay

The purpose of this report is to: (1) suggest reasons for the recently observed cownose ray predation on Rappahannock River oyster beds and the apparent increased abundance of the ray, and (2) recommend short- and long-term methods to control and/or manage cownose ray predation on commercially important sh1ellfish beds

Finfisheries Problems and Approaches

The fisheries data of principal concern at this conference are those which provide an accurate description of the harvest from the resource. Most often, one thinks of the standard reference fishery data from commercial fish landings: pounds by species, dockside dollar value, location of the catch, gear used, and number of fishermen. These data have been widely used by biologists and managers to evaluate the status of particular stocks and trends in the fishery. An example of a recent evaluation for Chesapeake Bay fisheries is Rothschild et ·a1. (1981). Several underlying truths must be borne in mind when discussing territorial seas fisheries management and the statistical database.https://scholarworks.wm.edu/vimsbooks/1152/thumbnail.jp

The displacement and loss of larval fishes from the Rappahannock and James rivers, Virginia, following a major tropical storm

Two days after Tropical Storm Agnes, the Virginia Institute of Marine Science (VIMS) established an anchor station at Mile 15 in the Rappahannock and Mile 10 in the James River. Both stations were in mainstream, manned constantly for 10 days, and took continuous current data from meters placed at 0, 6, 8, and 15 min the Rappahannock and 0, 4, 5, 8, and 14 min the James. Concurrently, 0.85 m diameter plankton nets of No. 1 nylon mesh were hung in the flowing surface water for 10 minutes hourly. A small collection of midwater (4 m) plankton samples was obtained from the James station. The shoal areas were not sampled for larval fish. The ichthyoplankton and zooplankton captured were preserved and later identified to species.https://scholarworks.wm.edu/vimsbooks/1078/thumbnail.jp

Assessment and Management of Atlantic and Gulf Menhaden Stocks

The organization of coastwide management programs for Atlantic menhaden, Brevoortia tyrannus, and Gulf menhaden, B. patronus, are described. Recent assessments of the status of the Atlantic and Gulf menhaden stocks are summarized. Estimates of population size and fishing mortalities are obtained from virtual population analysis, and are used in determining spawner-recruit relationships, spawning stock ratios, yield-per-recruit, and surplus production. Management issues are addressed in the framework of assessment results

Movement Of 1970 Year Class Striped Bass Between Virginia, New York And New England

Striped bass (Marone saxatilis) were tagged in Virginia beginning in 1968. The 1970 yearclass of striped bass was tagged both in Virginia and New York in 1972. Fish tagged in Virginia were returned from New York to Maine while fish tagged in New York were returned from the Maryland portion of the Chesapeake Bay and the Potomac River. These data indicated that fish migrate from rivers in which they were spawned at different ages and that fish that migrate as 2 year olds remain together as a group until they are 3+ years. Therefore, within the Chesapeake Bay area there are distinct river populations at least until these populations are 3+ years old.https://scholarworks.wm.edu/vimsbooks/1111/thumbnail.jp
