  • Evaluating the Efficacy of Predicting Bycatch Mortality Using Reflex Impairment through an Assessment of Crab Discards

    Creator:
    Yochum, Noëlle
    Abstract:
    All animals that interact with fishing gear are not necessarily captured, and all animals that are captured are not necessarily retained. Fishing practices and gear configuration, management regulations, and markets dictate which animals ultimately are retained or discarded. The impact of a fishery and the efficacy of management regulations can...

  • Seasonal floodplain wetlands as fish habitat in Oregon and Washington

    Creator:
    Baker, Cynthia F.
    Abstract:
    To begin to understand freshwater seasonal floodplain fish communities in the context of human alteration of the physical system, species introductions and wetland restoration efforts, I studied fish assemblages in fifteen seasonal floodplain wetlands within four geographic regions (coastal, upper Columbia River estuary, Puget Sound and eastern Oregon/Washington) in the...

  • Aspects of the early life history of juvenile salmonids in the Dungeness River Estuary

    Creator:
    Sather, Nichole K.
    Abstract:
    The decline of many Pacific salmon stocks has stimulated interest in the early life history and habitat requirements of juvenile salmon. Although estuarine habitat associations of juvenile salmon have been investigated in many coastal areas of the eastern Pacific Ocean, until recently, little was known about juvenile salmonid ecology within...

  • California condors in the Pacific Northwest : integrating history, molecular ecology, and spatial modeling for reintroduction planning

    Creator:
    D'Elia, Jesse
    Abstract:
    Reintroduction programs are increasingly being used to save animals from extinction and aid in their recovery. The California Condor (Gymnogyps californianus), one of the most endangered birds in the world, is a remarkable example of how reintroduction programs can help rapidly increase a species' population numbers and range following a...

  • Population Differentiation in two Northeastern Pacific Marine Species

    Creator:
    Curran, Lorne Sullivan
    Abstract:
    Population genetic techniques are now preeminent in differentiating wild populations. Natural resource managers rely on them in their efforts to restore viable populations of fish and wildlife. Overfishing adversely impacted Yelloweye Rockfish (Sebastes ruberrimus) on the U.S. West Coast in the late 20th century. Management actions included shutting down the...
