Spawning Activity and Migratory Characteristics of American Shad and Striped Bass in the Cape Fear River, NC. (Under the direction of Joseph E. Hightower) Anadromous fish populations within the Cape Fear River, NC have experienced declines since the late 1800s. Three low-head lock and dam structures contributed to this decline by limiting access to upstream habitat. I used egg sampling and sonic telemetry to characterize patterns of migration and spawning activity for American shad and striped bass. Plankton samples were taken below each lock and dam, and at two locations farther upstream. Distribution and stage of development of American shad eggs, as well as observed spawning activity, suggest that most American shad spawning took place below the lowermost lock and dam (river km (rkm) 97). Egg density decreased by an estimated 90% for each successive dam moving upstream. In 2007, 20 American shad and 20 striped bass were captured and transported to a release location upstream of the three locks and dams, where they were tagged with sonic transmitters and released. Sixty percent of American shad in 2007 moved 1 to 33 rkm upstream of the release site, at an average migration rate of 2.30 rkm/hr. All 2007 striped bass moved downstream upon release. However, two striped bass made secondary upstream migrations of 52 and 134 rkm, through two and three dams respectively, and at an average rate of 2.58 rkm/hr. In 2008, 20 American shad and 20 striped bass were captured, tagged with sonic transmitters, and released at their capture locations (all but two striped bass downstream of the first lock and dam). Sixty-five percent of American shad and 77% of striped bass made upstream movements past the lowermost lock and dam in 2008, with average migration speeds of 3.2 rkm/hr for American shad and 3.0 rkm/hr for striped bass. Furthermore, 35% of American shad and 25% of striped bass that made upstream movements were able to migrate upstream of the uppermost.

Book excerpt: This report describes the results of the twentieth 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 2017, evaluating hatchery programs, and contributing to coast-wide assessments (ASMFC 2007). We also report on two fishery-independent monitoring programs, one using staked gillnets in the Rappahannock River (year 2) and the other using anchor gillnets in the Chickahominy River (year 3; a major tributary of the James River),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 third year of a monitoring program for juvenile alosines by using nighttime surface trawls in the Chickahominy River and calculate an index of juvenile abundance. Additional objectives were to monitor bycatch of American shad in a permitted gill-net fishery and American shad and river herring in pound-net fisheries.
