  • Aging Giant Pacific Octopus using Beaks and Stylets for Better Stock Structure Assessment

    Creator:
    Yarbrough, Ashley
    Abstract:
    Despite being a highly charismatic and frequently exhibited organism, Giant Pacific Octopus (Enteroctopus dofleini) population dynamics are poorly understood. Basic monitoring data for this species is limited to bycatch and stomach contents of other fisheries species. An essential step to a better estimation of population size and productivity is to...

  • Skin Deep: An Assessment of New Zealand Blue Whale Skin Condition

    Creator:
    Barlow, Dawn R., Pepper, Acacia L., and Torres, Leigh G.
    Abstract:
    Skin condition assessment of wildlife can provide insight into individual and population health. Yet, logistics can limit skin condition assessment of large whales. We developed a standardized, quantitative protocol using photographs to assess skin condition of blue whales in New Zealand, and demonstrate the value gained by testing hypotheses, documenting...

  • Evaluating desiccated cyanobacteria Aphanizomenon flos-aquae for use as a biofertilizer on Swiss Chard

    Creator:
    Turk, Douglas E.
    Abstract:
    Non-toxic species of desiccated blue-green algae, or cyanobacteria, may offer potential for use as a fertilizer on irrigated crops. Here, the non-toxic cyanobacteria species Aphanizomenon flos-aquae (AFA), collected from Upper Klamath Lake, Oregon, was evaluated for use as a biofertilizer in a controlled experiment on Swiss chard “Bright Lights” (Beta...

  • Detecting Fish Vocalizations in American Samoa Using Machine Learning

    Creator:
    Munger, Jill
    Abstract:
    A deep neural network was developed and trained to identify the sounds of pomacentrids (damselfishes) in the National Park of American Samoa. Four years of continuous, passive acoustic data were recorded by a single stationary hydrophone. Deep neural networks enable the full utilization of such large datasets by automating laborious...

  • Environmental DNA: testing assumptions with experimentation

    Creator:
    Cousins, Christopher D.
    Abstract:
    This study used a factorial mesocosm design to quantify American bullfrog (Lithobates castebeianus) eDNA to assess the relationship between body size, density, and eDNA shedding rates.

  • New discovery leads to a whole new meaning of “trash fish”

    Creator:
    Chione, Andrew
    Abstract:
    This paper is an assignment for my Ichthyology class at Oregon State University. I was tasked with creating a new fish species that is scientifically possible and telling a fictional story of its discovery.
