The Relationship Between Ohio River Bass Tournament Success Rates, Forage Fish Abundance And Environmental Conditions, Jeffrey V. Ginger
The Relationship Between Ohio River Bass Tournament Success Rates, Forage Fish Abundance And Environmental Conditions, Jeffrey V. Ginger
Theses, Dissertations and Capstones
Due to increasing pressure from Ohio River bass anglers with regard to decreasing catch rates in 1981,1990, and 1997, the West Virginia Division of Natural Resources (WVDNR) initiated a study of black bass populations. The Ohio River Valley Water Sanitation Commission (ORSANCO), in conjunction with state and Federal agencies, has collected population data on Ohio River fishes at lock chambers and has measured various water quality parameters since 1957. That data coupled with Ohio River bass tournament data collected by the DNR since 1975 and other fishery data sets provided a historic look into the variability of angler success. These …
Food Habits Of Salmo Trutta And Salvelinus Fontinalis (Pisces: Salmonidae) In Relation To Seasonal Changes And Mitigative Liming Effects In Dogway Fork Of The Cranberry River, West Virginia., Jason A. Morgan
Theses, Dissertations and Capstones
Dogway Fork, a tributary of the Cranberry River in West Virginia, is acidic due to acid precipitation and poorly buffered soils. This study is part of a long-term investigation involving the effects of continuous limestone neutralization on the fishes and benthos of an acid stream. Prior to treatment in 1988, the stream had a pH of 4.5 and there were no fish present. Since treatment began, the pH of the stream has risen to 6.8. Nine species of fish have been collected and six species have reproduced following the improvement in water quality. Densities of specific acid-sensitive benthic macroinvertebrates have …

Food Habits And Diet Overlap Of Age-1 And Older Walleye And White Bass In Lake Poinsett, South Dakota, Andrew B. Starostka
Food Habits And Diet Overlap Of Age-1 And Older Walleye And White Bass In Lake Poinsett, South Dakota, Andrew B. Starostka
Electronic Theses and Dissertations
White bass Marone chysops and walleye Stizostedion vitreum coexist in several of the large glacial lakes in eastern South Dakota. I collected age-1 and older white bass and walleye in Lake Poinsett, South Dakota during May, July and September, 1998 to determine food habits and diet overlap using percent by weight to describe diets and Schoener's index (Cxy) to determine diet overlap. Macroinvertebrates were common prey items for white bass in all length groups during all sample dates. The primary macroinvertebrates consumed by white bass were corixids, amphipods and dipterans. Fish, as a group, were second in diet importance over …
Seasonal Investigation Of Native Fishes And Their Habitats In Missouri River And Yellowstone River Backwaters, Shannon J. Fisher
Seasonal Investigation Of Native Fishes And Their Habitats In Missouri River And Yellowstone River Backwaters, Shannon J. Fisher
Electronic Theses and Dissertations
Interactions between the Missouri River and its floodplain have been severely degraded due to channelization and impoundment. Ecologists have assumed that backwaters are a critical habitat component for certain life stages of native fishes; however, documented relationships are limited. During this study, I monitored fishes, invertebrates, and habitats to help determine the importance of backwaters to native fishes of various life stages, and to assess the changes that occur in habitat characteristics and invertebrate densities during periods with differential connectivity. Seven assemblages of fishes, identified with catch-per-unit-effort data, had at least some relationship with the backwaters. The assemblages included two …
Institutional Arrangements For Cooperative Fisheries Management: A Case Study Of The Newfoundland And Labrador Northern Shrimp Fishery, Bram F. Noble
Institutional Arrangements For Cooperative Fisheries Management: A Case Study Of The Newfoundland And Labrador Northern Shrimp Fishery, Bram F. Noble
Theses and Dissertations (Comprehensive)
The intent of this study is to examine the present institutional arrangements of the Newfoundland and Labrador Northern shrimp fishery, to identify the roles of cooperative fisheries economic development corporations and make recommendations for institutional improvements. There are a number of institutional and organizational arrangements more favorable for fisheries management and development than present ones (Bishop, 1981; Bromley, 1982; McCay and Acheson, 1987; Pinkerton, 1989). Jentoft and McCay (1995) identified the need for this type of research in fisheries management in order to understand the complexity of relationships in fisheries management and to develop more effective means of fisheries management …
A Spatial And Temporal Analysis Of Riparian Vegetation Along Satus Creek On The Yakama Indian Reservation, Kathryn Gellenbeck
A Spatial And Temporal Analysis Of Riparian Vegetation Along Satus Creek On The Yakama Indian Reservation, Kathryn Gellenbeck
All Master's Theses
Satus Creek provides critical habitat for the Yakima River Basin steelhead. A diverse community of riparian vegetation is important for healthy fish habitat; vegetation changes can affect shade, cover, channel structure, water quality, and food availability. The purpose of this thesis is to analyze and illustrate riparian vegetation change, both temporally and spatially, along three separate reaches of Satus Creek. A Geographic Information Systems approach was applied to assess the vegetation change by comparing plant species composition and density on 1949 and 1995 aerial photographs. The GIS approach allowed patterns and trends in the vegetation to be identified. In less …

Growth And Yield-Per-Recruit Modeling Of Spot (Leiostomus Xanthurus) In The Chesapeake Bay, And A Comparison Of Biological Reference Points, Kevin Ray Piner
Growth And Yield-Per-Recruit Modeling Of Spot (Leiostomus Xanthurus) In The Chesapeake Bay, And A Comparison Of Biological Reference Points, Kevin Ray Piner
Biological Sciences Theses & Dissertations
Spot were sampled from the Chesapeake Bay commercial fishery from 1993–1995 to determine if spot are overfished. Transversely sectioned otoliths were determined to be the most appropriate structure for ageing spot. It was determined that spot have a high natural mortality rate (M = 0.9) and fast growth (K = 0.6). This combination of M and K makes spot relatively impervious to growth overfishing as determined by yield-per-recruit modeling. Because spot are nearly impervious to growth overfishing, management thresholds based on yield-per-recruit modeling may be inappropriate. In addition, the combination of high M and fast K makes it possible to …
