Abstract:: Distribution of Vibrio parahaemolyticus in Oregon and Washington oystergrowing areas was studied between November 2002 and October 2003. V. parahaemolyticus was detected in 14.3% of oyster, 23.0% of seawater, and 44.4% of sediment samples with very low levels (≤7.4 MPN/g) of pathogenic strains being detected in oysters. Occurrence of V....

Abstract:: The importance of seagrasses (families Posidoniaceae, Zosteraceae, Hydrocharitaceae and Cymodoceaceae) to estuarine communities is widely accepted and this, combined with their continued decline throughout the world, have resulted in a need to better understand the factors affecting their growth and reproduction. Conservation and restoration of seagrasses will require an understanding...

Creator:: Cassidy, Katelyn M.
Abstract:: Determining age in crustaceans is inherently imprecise because they molt periodically and do not retain hard structures throughout their lifespan. Morphological measurements, such as carapace length, are often used to estimate age because methods for direct ageing do not exist. However, variability in individual growth rate and molt frequency can...

Abstract:: The pesticide carbaryl is applied annually to tidelands in Willapa Bay and Grays Harbor, WA to control populations of burrowing shrimp which modify sediments making the habitat unsuitable for oyster culture. Fish trapped on sprayed mudflats are often killed, but little is known about effects on fish present in subtidal...

Creator:: Sund, Daniel M.
Abstract:: The introduction of non-native species often results in fundamental changes in the structure and function of disturbed environments. In the Pacific Northwest (PNW), the introduced seagrass Zostera japonica is rapidly expanding in distribution, impacting stakeholders and public use of the intertidal. Z. japonica’s expansion has prompted a number of different...
