Comparison of Olympia oyster habitat restoration methods in Yaquina Bay, OR

To determine the efficacy of different methods of oyster habitat restoration methods in enhancing juvenile life-history traits, this study compared the settlement, growth and mortality of wild juvenile Olympia oysters among three shell treatments: (1) bagged shells and (2) loose shells, which are commonly used methods of oyster habitat restoration, and (3) rafted-line shells, which is a method used by the Oregon Oyster Farm of Yaquina Bay to commercially grow their Pacific oysters.

Comparison of larval development in domesticated and naturalized stocks of the Pacific oyster Crassostrea gigas exposed to high pCO2 conditions

Ocean acidification (OA) has had significant negative effects on oyster populations on the west coast of North America over the past decade. Many studies have focused on the physiological challenges experienced by young oyster larvae in high pCO2/low pH seawater with reduced aragonite saturation state (Ωarag), which is characteristic of OA. Relatively few, by contrast, have evaluated these impacts upon fitness traits across multiple larval stages and between discrete oyster populations.

Analysis of stress factors associated with KHV reactivation and pathological effects from KHV reactivation

Koi herpesvirus (KHV) is a highly pathogenic virus of common carp and koi. KHV becomes latent in recovered koi or exposed koi without symptoms, and the latent infection can reactivate under stress conditions. KHV reactivation from latency often occurs when water temperature rapidly rises above 17 °C. Dissolved O2 is lower at ≥17 °C than at non-stress temperatures ≤15 °C.
