Smallmouth Bass (Micropterus Dolomieu) Population Characteristics And An Evaluation Of Management Responses In Two West Virginia Watersheds, Jacob D. Harrell
Graduate Theses, Dissertations, and Problem Reports
Smallmouth Bass (Micropterus dolomieu) population characteristics were examined within the Tygart and Cheat River watersheds of north-central West Virginia. Growth, mortality and recruitment were examined for each individual population prior to modeling potential effects of various management schemes. Smallmouth Bass were sampled for total length and weight, aged using sagittal otoliths and sexed through observations of gonadal or ovarian development. Growth for each population was examined using von Bertalanffy growth models and assessed for variation among populations. Population demographic characteristics differed between and among populations, most noticeably between riverine and lacustrine habitat, whereby growth, mortality and recruitment were higher …
Thermal Performance Of Growth At Consumption Maximum (C-Max) And Routine Metabolic Rate (Rmr) In Brook Trout Salvelinus Fontinalis From Four Populations In Central Appalachia, Cory Michael Hartman
Thermal Performance Of Growth At Consumption Maximum (C-Max) And Routine Metabolic Rate (Rmr) In Brook Trout Salvelinus Fontinalis From Four Populations In Central Appalachia, Cory Michael Hartman
Graduate Theses, Dissertations, and Problem Reports
Growth of an individual is the end result of many physiological processes stemming from the consumption of food items. These processes can be influenced by many variables including temperature. Current bioenergetics models for Brook Trout Salvelinus fontinalis suggest growth increases with temperature until an inflection point of 20.2°C. With a warming climate, and water temperatures expected to rise, the ability of a population to adapt to the warming environment is crucial to the survival of the species. For this study we sought to see how spatial variation would influence the specific consumption, conversion efficiency, and specific growth at consumption maximum …
