Genetic evaluation of American shad Alosa sapidissima restoration success in James River, Virginia
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 …

Migratory patterns of American shad (Alosa sapidissima) revealed by natural geochemical tags in otoliths
… In an assessment of river-specific signatures in American shad (Alosa sapidissima), an anadromous clupeid native to the Atlantic coast of North America, stable isotope and elemental ratios in otoliths of juvenile American shad produced accurate natal tags from 12 rivers. Significant inter-annual …

Spatial and Temporal Patterns of Anadromous Fish Passage at Boshers Dam Vertical Slot Fishway on the James River, Richmond, Virginia
… was used to evaluate environmental predictors of American shad (Alosa sapidissima) and sea lamprey (Petromyzon marinus) passage. The ecological effects of restoring connectivity to upstream habitat for gizzard shad (Dorosoma cepedianum) and blue catfish (Ictalurus furcatus) are also discussed. …

Feeding Ecology of Invasive Catfishes in Chesapeake Bay Subestuaries
… species of concern. Species of concern include American Shad, American Eel, and river herring, which are imperiled, and blue crab, which support valuable fisheries in Chesapeake Bay. Predation of American Shad, American Eel, and river herring was rare (max predicted occurrence in Blue Catfish …

Overwintering abundance and distribution of striped bass (Morone saxtilis) in the Hudson River estuary using hydroacoustic techniques
… was developed for white perch (Morone americana) and striped bass (Morone saxtilis). This target strength to length relationship was compared to two standard relationships (Love and Foote). The calculated relationship was not found to be significantly different from Love's equation, but …

CHARACTERIZATION OF MICROSATELLITE LOCI AND PILOT POPULATION GENETIC ANALYSIS IN HICKORY SHAD, ALOSA MEDIOCRIS
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 …

Bayesian hierarchical approaches to analyze spatiotemporal dynamics of fish populations
… has significant influence on stock estimates. American Shad (Alosa sapidissima), Hickory Shad (A. mediocris) and river herrings, including Alewife (A. pseudoharengus) and Blueback Herring (A. aestivalis), are anadromous pelagic fishes that spend most of the annual cycle at sea and enter coastal …
