North Carolina Wildlife Resources Commission (NCWRC) staff provided 479 American Shad Alosa sapidissima samples in 2022 for parentage-based tagging (PBT) analysis. Fin clips were from the Roanoke River (n = 185) and Neuse River (n = 294). Hatchery contribution was 47.0% for Roanoke River adults and 2.4% for Neuse River adults. The effective population estimate (Ne) for 2022 Roanoke River American Shad was 637 (95% confidence interval = 416–1259) and for Neuse River American Shad was 10,558 (95% confidence interval = 1525–infinite)--Page [1].

This book was released on 2013-06 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States Government Printing Office (GPO) was created in June 1860, and is an agency of the the U.S. federal government based in Washington D.C. The office prints documents produced by and for the federal government, including Congress, the Supreme Court, the Executive Office of the President and other executive departments, and independent agencies. The Coastal Zone Information Center (CZIC) collection provides access to nearly 5,000 coastal related documents that the U.S. Government Printing Office (GPO) received from the National Oceanic and Atmospheric Administration (NOAA) Central Library. The collection provides almost 30 years of data and information crucial to the understanding of U.S. coastal management and NOAA's mission to sustain healthy coasts. This is one of their documents.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The American shad Alosa sapidissima has experienced severe declines throughout its native range due to habitat degradation, fragmentation, and over-fishing. Hatchery supplementation is often used for stock restoration, but the effects of supplementation on population structure and genetic diversity are rarely assessed. This study employed molecular markers to evaluate how supplementation of the James River American shad population with Pamunkey River origin larvae since 1994 has impacted genetic diversity and population structure. Population genetic parameters of other major Chesapeake Bay tributaries (Susquehanna, Rappahannock, Potomac, and Nanticoke) also were characterized. Prior to stocking, the James and Pamunkey populations exhibited subtle genetic differentiation, which was absent among post-supplementation samples, presumably due to the stockings. A similar situation was observed among other shad populations of Chesapeake Bay tributaries which were subtly differentiated in the 1990s but lacked any credible among-population differentiation among contemporary samples. Genetic diversity of the James River shad population was high prior to stocking, and remained high throughout years of intensive supplementation, yet the current population decline suggests that the James River shad population still has not recovered. Despite harvest curtailment, elimination of the ocean intercept fishery, and widespread supplementation efforts, Chesapeake Bay tributary American shad populations are collectively at their lowest levels in recorded history. Therefore, success of other restoration goals such as creation of fish passage in James River was investigated in a concurrent radio telemetry study to assess passage at Bosher's Dam fishway. Ninety-four American shad were radio-tagged on the spawning grounds below Bosher's Dam. Approximately one-half of the tagged shad were detected at the escapement receiver within 24 hours after tagging, and the average residence times of remaining shad were approximately one week. No tagged shad were detected above Bosher's Dam. These results imply that restricted passage through Bosher's Dam fishway may be an important factor in the failure of James River American shad to recover. Therefore, improving passage at migratory barriers such as Bosher's Dam, in conjunction with a continued Bay-wide fishing moratorium, may be more beneficial to shad restoration efforts in James and other Chesapeake Bay tributaries than continued supplementation.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The hickory shad (Alosa mediocris) is a relatively understudied species of the anadromous fish sub-family Alosinae. This study, the first population genetic analysis of this species, employed 12 neutral microsatellite loci to estimate genetic diversity and population structure in tributaries of lower Chesapeake Bay, Virginia including James River and its tributaries (Appomattox and Chickahominy Rivers), Rappahannock River, and Pamunkey River. Genetic variation was extremely low. Estimates of observed heterozygosity were lower than expected heterozygosity. Significant population structure was detected among the six samples (FST = 0.093, p = 0.01). Effective population sizes were low (Ne ranged from 2 to 134). The lack of genetic diversity, especially compared to that of the American shad, was striking and could be the result of a bottleneck that took place more than thirty years ago which may plausibly account for the low genetic variation observed across all populations.
