  • The identification of Dungeness crab from the power spectral density function of their acoustic signature

    Creator:
    Eghbali, Hassan J.
    Abstract:
    The power spectral density of the acoustic signature of Dungeness crab was calculated by the use of digital computer. The signal produced by the Dungeness crab was an analog signal. Therefore a conversion of the signal from analog to digital was necessary. This was done by sampling the acoustic signature...

  • System design for Dungeness crab processing

    Creator:
    Adams, Burton Warren
    Abstract:
    Dungeness crab is an important fishery on the Pacific Coast. The processing subsystem of the fishery is hampered by a variety of problems that have acted to impede technological innovations that could improve efficiency and sanitation in seafood plants. This paper provides background for problems encountered by the processors, discusses...

  • Prediction of abundance of harvestable Dungeness crab (Cancer magister)

    Creator:
    Stefferud, Jerome Arthur
    Abstract:
    A method for predicting the harvest of commercial Dungeness crab (Cancer magister) one year in advance of the fishing season is described. The technique is based on the hypothesis that the relative abundance of sub-legal crabs one year is directly proportional to the harvest of legal crabs the following year....

  • Some economic considerations in Dungeness crab marketing

    Creator:
    Wix, John Robert
    Abstract:
    The purpose of this study is to describe Dungeness crab marketing from the ocean floor to the ultimate consumer; to identify relations among the Oregon Dungeness crab industry, the Pacific Coast Dungeness crab industry, and the Alaska King crab industry; and to specify the relationships between fishermen's prices for Dungeness...

  • Skill design, evaluation, and implementation of improved Dungeness crab meat extraction methods

    Creator:
    Willis, George Paul
    Abstract:
    The Dungeness crab fishery is the largest and oldest known shellfish fishery of the North Pacific coast of North America. The stability and development of this fishery is seriously hampered by increasing meat extraction costs and labor shortages. Alternative solutions to offset the increasing costs and labor shortages include: 1)...

  • Evaluation of dungeness crab pots as platforms of opportunity for ocean-observing research

    Creator:
    Childress, Jeremy L.
    Abstract:
    Oregon Fishermen in Ocean Observing Research (OrFIOOR) is a cooperative research program between ocean scientists and fishermen in the Pacific Northwest. Dungeness crab fishermen attach sensor packages (temperature and dissolved oxygen) to crab pots. The pots serve as platforms of opportunity for ocean observing. This study examines three principle questions...

  • The effects of PCB exposure on the behavior of the shore crab Hemigrapsus oregonensis

    Creator:
    Pearson, Walter H.
    Abstract:
    The behavior of the shore crab Hemigrapsus oregonensis was assessed with and without exposure to polychlorinated biphenyls (Aroclor 1260). After describing the crab's behavioral repertoire, activity budgets were developed from observations of the time crabs spent in 20 categories of shelter use, posture, and activity while held in habitat replicas...

  • Genetic Connectivity of Dungeness Crab (Cancer magister) in the California Current System and Puget Sound

    Creator:
    Jackson, Tyler M.
    Abstract:
    Understanding connectivity among exploited populations is critical to their sustainable management and long-term viability. In the marine environment, estimates of connectivity often rely on the use of genetic markers, as dispersal primarily occurs during a planktonic larval phase which is difficult to track using direct methods. In this thesis, we...
