Reports

This report describes the results of the twenty-sixth year of a continuing study to estimate the relative abundance and assess the status of American shad (Alosa sapidissima) stocks in Virginia by monitoring the spawning runs in the James, York and Rappahannock rivers in spring 2023, evaluating hatchery programs, and contributing to coast-wide assessments (ASMFC 2007, ASMFC 2020).

Monitoring Relative Abundance Of American Shad In Virginia's Rivers Annual Report 1999, John E. Olney Sr., John M. Hoenig Jul 2000

Monitoring Relative Abundance Of American Shad In Virginia's Rivers Annual Report 1999, John E. Olney Sr., John M. Hoenig

Reports

A moratorium on the taking of American shad (Alosa sapidissima) in the Chesapeake Bay and its tributaries was established by the Virginia Marine Resources Commission (VMRC) beginning 1 January 1994. The prohibition applied to both recreational and commercial fishers. The moratorium was imposed at a time when commercial catch rates of American shad in Virginia's rivers were experiencing declines. Data from the commercial fishery were the best available for assessing the status of individual stocks. Catch-per-unit-effort (CPUE) data were compiled from logbooks that recorded landings by commercial fishermen using staked gill nets at various locations throughout the middle reaches of …

Biology And Management Of River Herring And Shad In Virginia : Annual Report, Anadromous Fish Project 1974, Walter J. Hoagman, John V. Merriner, William K. Kriete, Woodrow L. Wilson

Reports

This annual report covers the period October, .1973 through September, 1974. It is the seventh report generated by' the project, with 3-year completion reports prepared in 1970 and 1973. The project· is continuing at VIMS and each year allows stronger conclusions to be made concerning trends in the basic population parameters studied.

The 1970-1973 completion report was widely distributed in Virginia, libraries at fishery science institutes, and throughout the National Marine Fisheries Service. The completion report analyzed data from the entire history of the project. In many cases the entire summarized data core for a particular segment was presented, e.g. …


Biology And Utilization Of Anadromous Alosids: Annual Progress Report (October 1, 1968 - September 30, 1969, Jackson Davis, Joseph P. Miller, J. Ernest Warriner Jan 1969

Biology And Utilization Of Anadromous Alosids: Annual Progress Report (October 1, 1968 - September 30, 1969, Jackson Davis, Joseph P. Miller, J. Ernest Warriner

Reports

Estimates of average annual mortality rates were derived. from the decline in numbers of repeat river herring spawners each year. in the Rappahannock and Potomac Rivers. The 1961 year-class contributed slightly more than 6 million fish to the fishery since 1965 while the 1962 year-class contributed nearly 5 million fish. Estimates could not be made for the James and York Rivers because the catch could not be measured. Fishing effort generally declined from 1968 in all major rivers with the Potomac River exhibiting the greatest decline. The catch of river herring in 1969 was generally lower than in 1968. Shad …


Biology And Utilization Of Anadromous Alosids: Annual Progress Report (October 1, 1967 - September 30, 1968), Jackson Davis, J. Ernest Warinner, Joseph P. Miller Jan 1968

Biology And Utilization Of Anadromous Alosids: Annual Progress Report (October 1, 1967 - September 30, 1968), Jackson Davis, J. Ernest Warinner, Joseph P. Miller

Reports

Scales were collected from alewife, blueback, American shad and hickory shad in each tidal river system in Virginia at weekly intervals. Reading of alewife scales is complete to date and the alewife catch from the York and Rappahannock Rivers has been analyzed for sex composition and spawning history.

Lack of catch records from the James and Potomac Rivers precludes analysis of these populations. Fishing effort in the major rivers during 1968 was equal to that of 1967. The catch of river herring increased approximately .4 million pounds over 19_67 increasing catch per unit of effort to the highest level on …
