Abstract

The Virginia Department of Game and Inland Fisheries (VDGIF) has been releasing larval American shad into the James and York river systems since 1993 and these fish are given river-specific marks before release. Our in-river monitoring program had established that we could estimate the proportion of fish returning to spawn in the rivers that have hatchery marks. Furthermore, we were able to obtain a sample of 200 fish from the intercept fishery off Chincoteague Island, Virginia, in 2000 and screening of the otoliths by VDGIF personnel revealed the presence of one fish with a James River hatchery mark and one with a York River mark. No marks from any other river were found. Thus, it appeared that hatchery markings would allow the opportunity to estimate the proportion of Virginia stocks that were harvested in the offshore fishery. On the basis of these preliminary findings, we proposed the present study.
