This book was released on 1997-05-31 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents a synthesis of basic biological and conservation data for more than 30 species of sturgeons (Acipenseridae), paddlefishes (Polyodontidae) and their fossil allies in the order Acipenseriformes. Since the Jurassic, the four families of sturgeon-like fish have been restricted to the Holarctic, where until very recently they flourished in most major river systems. Today, however, virtually all species of sturgeons and paddlefishes face difficult conservation issues. Papers in the first section of this volume examine paleontology, systematics, evolution and basic biology of Acipenseriformes. The second section of this volume details current conservation status for most of the world's living species of Acipenseriformes. These papers mark the first attempt to make such a global review of recent data from across the northern hemisphere. The emerging picture is discouraging, for negative anthropogenic impacts range from overfishing to water pollution, to dams and water diversion projects, and all species are threatened to some degree. The third section of the volume considers specific human impacts and responses to conservation issues. These include: the Aral Sea ecological disaster and its impact on native sturgeons; a review of methods for restoring sturgeon populations; the use of molecular techniques in developing conservation strategies; the extreme sensitivity of sturgeons and paddlefishes to overfishing; and the history of a recently convicted caviar poaching ring. The volume's summary reviews the status of all extant species and notes future directions for research on behavior, ecology and population biology that could lead to better co-ordinated international conservation efforts.

Available in PDF, EPUB and Kindle. Book excerpt: This book addresses specific water quality and pollution problems and documents the changes that occurred during the critical transition period when PCB dumping was discontinued and water treatment plants came into increased use. It will appeal to fishery biologists working with Atlantic coast species, people involved with estuaries worldwide, and to all environmentalists interested in the history of the landmark Hudson River Settlement Agreement. The signing of the Hudson River Settlement Agreement ended more than a dozen years of controversial court battles over the placement of electric generating plants on the Hudson River estuary. Much of this agreement was based on original field research, the most compelling of which is found in this book. Fisheries Research in the Hudson River includes a summary of existing fisheries data bases, with comments on their strengths and weaknesses and a guide to their availability, as well as discussions of the natural history of striped bass, white perch, river herrings, tomcod, sturgeon, and a very important food source, the amphipod gammarus tigrinus. It also proposes a management plan for sturgeon, a plan based on an age-structured population model that demonstrates the practical application of basic scientific data.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the research was to determine if shortnose sturgeon, Acipenser brevirostrum, occur within the Neuse River, North Carolina. Shortnose sturgeon historically occurred in most major Atlantic Coast rivers from Saint Johns River, New Brunswick, Canada to St. Johns River, Florida. Anecdotal evidence suggests that a population of shortnose sturgeon once occurred in the Neuse River, North Carolina, but their current status was unknown. In compliance with the National Marine Fisheries Service shortnose sturgeon sampling protocol, a two-year intensive gillnet survey was conducted in order to determine the population status of shortnose sturgeon within the Neuse River. Habitat surveys showed that the lower Neuse River, where shortnose sturgeon would be expected to occur during summer, was severely hypoxic in June - September of 2001 - 2002. No shortnose sturgeon were observed during the two-year survey (> 200 h of netting effort) although four juvenile Atlantic sturgeon were encountered. These two species occupy similar habitats in other river systems. A juvenile Atlantic sturgeon tagged with a transmitter moved upstream of the unsuitable habitat and remained in a restricted area until late fall, when water quality improved due to increased flows and lower temperatures. The probability of detection for varying population sizes of shortnose sturgeon was calculated in order to determine if adequate sampling had been completed to conclude an absence of shortnose sturgeon in the Neuse River. The detection analysis stated that a population size of 50 or more individuals should be detected in 200 h of netting effort. Therefore, based on our sampling efforts, we hypothesize that shortnose sturgeon are extirpated from the Neuse River. We believe that poor water quality is a key factor in the extirpation of shortnose sturgeon in the Neuse River. Population recovery may be impossible until habitat quality can be improved. Finally, we observed that shortnose sturgeon have a.

Book excerpt: The Environmental Protection Agency (EPA) is proposing to implement remedial actions at the Marathon Battery Co. Site (MBCS) in Cold Spring, New York, pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act, as amended by the Superfund Amendments and Reauthorization Act (CERCLA/SARA). The shortnose sturgeon (Acipenser brevirostrum), a federally-listed endangered species, is known to occur in the Hudson River in the vicinity of the site. Portions of the proposed remedial actions will take place in aquatic habitats of, and associated with, the Hudson River. Accordingly, as part of its efforts to comply with the requirements of the Endangered Species Act (ESA), EPA has prepared a Biological Assessment (BA) of the potential impacts of the proposed remedial actions on the shortnose sturgeon.
