Creator:: Chatfield, Marcus W.
Abstract:: Devaleraea mollis (Pacific Dulse) is becoming a popular food for human consumption. Previously, Pacific Dulse has been used as a nutrient source for cultured abalone species, with some historical food use by indigenous peoples, while the closely related Atlantic dulse (Palmaria palmata) has a long-documented history of use in cuisine...

Creator:: Quennessen, Victoria I.
Abstract:: Fisheries management that is based on quantitative assessment has commonly relied on estimating the unfished biomass of a fished stock to compare current and historical population size. Developing predictive models for this requires many years of catch and abundance data. Smaller, new, or mainly recreational fisheries may not have the...

Abstract:: Oysters are a large part of the American aquaculture market, and the oyster farming industry was valued at over 1 billion dollars in 2021. However, oyster farmers often face issues surrounding the mortality rates of their stock. One cause of this is infections caused by Vibrio coralliilyticus (Vcor), a bacterium...

Abstract:: Marine heatwaves have become more common over the past several years. The 2014-2015 ‘warm blob’ had profound effects on marine ecosystems in the Northeast Pacific. Given the particular habitat needs of Chinook Salmon (Oncorhynchus tshawytscha) we wanted to examine the impacts of the heatwave on Chinook depth distribution. We examined...

Creator:: Hutton, Sara J.
Abstract:: Based on current trends both pesticide and plastic production are expected to continue to rise in the coming decade. A growing global population coupled with the effects of climate change are the main drivers of increased pesticide use.

Creator:: Fleener, Henry R.
Abstract:: Standard larval Pacific oyster (Crassostrea gigas) rearing systems can be described as either static or continuous flow. While rearing oyster larvae in static cultures can be a low-cost and simple method, static systems require significant husbandry effort, floorspace and can produce highly variable results due to environmental variance among cultures....

Creator:: Swieca, Kelsey
Abstract:: Most marine fishes experience high rates of mortality during their early life history stages with far reaching consequences for adult population dynamics. Within a few weeks of hatching, relatively small changes in larval growth and mortality rates can lead to orders of magnitude variability in year-class strength. Growth and survival...
