Available in PDF, EPUB and Kindle. Book excerpt: Populations of American shad (Alosa sapidissima) have declined from historical levels due to overfishing, decreased water quality and habitat losses including those due to dam construction. One approach for restoring these populations is to identify suitable habitat upstream of dams that could be restored through dam removal or by providing fish passage. The goal of this research is to identify and characterize potential spawning habitat for American shad in the upper Roanoke River basin of Virginia, above Kerr Reservoir. Five mainstem rivers that are upstream of the Roanoke Rapids, Gaston, and Kerr dams (Big Otter, Staunton, Banister, Dan, Hyco) were the focus of this research. Roanoke Rapids Dam is the first obstruction to American shad spawning migration in the Roanoke River basin, and just completed the FERC (Federal Energy Regulatory Commission) relicensing process in 2004. One of the provisions of the new license is to evaluate a trap and transport program for spawning American shad. Characterizing the habitat above the dam, in terms of suitability, is an important step in predicting the benefits of fish passage. A detailed physical habitat assessment, including monthly water quality monitoring, indicated that the Banister and Hyco rivers consistently had lower dissolved oxygen concentrations and may provide lower quality habitat for American shad compared to the other rivers. However, according to the current published Habitat Suitability Index (HSI) model, which incorporates surface water temperature and current velocity as criteria for suitable habitat, the five rivers appear to contain suitable habitat with HSI values ranging from 0.83 to 1.00 during May. I constructed a modified HSI model with surface water temperature and current velocity, as well as dissolved oxygen, pH and a component for substrate composition. The modified model suggested that the Big Otter and Staunton rivers would provide the highest quality spawning habitat for American shad becaus.

This book was released on 2018 with total page 110 pages. Available in PDF, EPUB and Kindle. 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.

Available in PDF, EPUB and Kindle. Book excerpt: The interactions between wild bird populations (many protected by law) and fish, particularly those under commercial culture or part of a fishery is subject of much controversy. Ecological, environmental and conservation pressures run alongside commercial pressures on exploited fish populations. This exciting book draws together contributions from all over the world to provide a fascinating insight into many case studies and conflicts in managed situations as well as looking at the overall ecology of such interactions in normal un-managed ecosystems.
