Abstract
This report describes the results of the twenty-seventh 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 2024, evaluating hatchery programs, and contributing to
coast-wide assessments (ASMFC 2007, ASMFC 2020). We also report on two fishery independent
monitoring programs using anchor gillnets in the Rappahannock River
(year 7) and a major tributary of the James River, the Chickahominy River (year 10), to
determine relative abundance and stock structure for the adult spawning run of river
herring (A. pseudoharengus, and A. aestivalis). Further, we report on the year 10 of a
monitoring program for juvenile alosines by using nighttime surface trawls in the
Chickahominy River and present an index of juvenile abundance from this survey. An
additional result of this study was analysis of bycatch of American shad in a permitted
gill-net fishery and American shad and river herring in pound-net fisheries.
