Pathogens Associated with Trout Populations in Shenandoah National Park and the Relationships to Fish Stocking Practices
Restrictive fish stocking policies in National Parks were developed as early as 1936 in order to preserve native fish assemblages and historic genetic diversity. Despite recent efforts to understand the effects of non-native or exotic fish introductions, park managers have limited information regarding the effects of these introductions on native fish communities. Shenandoah National Park was established in 1936 and brook trout (Salvelinus fontinalis) restoration within selected streams in the park began in 1937 in collaboration with the Virginia Department of Game and Inland Fisheries (...
Pathogens Associated with Native and Exotic Trout Populations in Shenandoah National Park and the Relationships to Fish Stocking Practices
Threats to native fish populations from practices such as fish stocking and from invasive and non-native species and their associated disease concerns are important natural resource management issues in National Parks. Prohibitive or restrictive fish stocking policies in National Parks were developed as early as 1936 in order to preserve native fish assemblages and genetic diversity. Despite recent efforts to understand the effects of non-native or exotic fish introductions, park managers have limited information regarding the effects of these introductions on native fish communities....
Zoonotic Fish Disease and Adaptive Fishery Management: Considerations for Striped Bass (Morone saxatilis) from the Chesapeake Bay
Mycobacteriosis is a widespread, chronic disease of estuarine fishes. Recent studies by scientists at the National Fish Health Research Laboratory, Leetown, West Virginia and the Virginia Institute of Marine Science, Gloucester, have shown infection rates in striped bass (Morone saxatilis) of up to nearly 62% in certain Virginia tributaries to Chesapeake Bay (Bay). Of the several mycobacterial species known to infect striped bass from the Bay, several are known to be zoonotic including M. marinum and M. fortuitum. In this paper we discuss the incidence and prevalence of mycobacterial...
Persistent and Emerging Diseases of Freshwater and Marine Fishes in the Southeast: Implications for Fishery Management
Several diseases of fish present challenges to both fishery managers and aquaculturists in the Southeast. Emerging diseases along with a suite of known and persistent diseases can present management challenges for native species and biodiversity, can cause loss of recreational fishing opportunities, and can affect local economies or reduce profitability in commercial aquaculture. Emerging diseases such as mycobacteriosis in striped bass, epizootic ulcerative syndrome in menhaden, and spring viremia of carp present some new challenges to fishery managers. Likewise, recurring epizootics...
