From Alan Trimble Hello everyone, Samples from this morning indicate that Pacific Oyster larvae are beginning to set throughout the Bay. Larval counts are slowly dropping as the larvae grow – much more quickly than cohorts of recent years. Here are the counts from samples during the 5:30AM high water:

[Oyster_seed_group] August 18, 2011 Willapa Oyster Bulletin
From Alan Trimble Hello All, We have completed our duplicate blind counts from yesterday evening’s pump samples. We can confirm that after a wait of several years we finally have a cohort of Pacific Oyster larvae that are surviving and growing to setting size in measurable numbers. This group is
The great oyster crash
BY ONEARTH, 18 AUG 2011 — This OnEarth column was written by Eric Scigliano. In the summer of 2007, something strange and troubling happened at the Whiskey Creek Shellfish Hatchery on Netarts Bay in Oregon, which raises oyster larvae for shellfish growers from Mexico to Canada. The hatchery’s “seed,” as
Effect of carbonate chemistry alteration on the early embryonic development of the Pacific Oyster (Crassostrea gigas)
Posted on EPOCA: 12 Aug 2011 Ocean acidification, due to anthropogenic CO2 absorption by the ocean, may have profound impacts on marine biota. Calcareous organisms are expected to be particularly sensitive due to the decreasing availability of carbonate ions driven by decreasing pH levels. Recently, some studies focused on the early
Quantifying rates of evolutionary adaptation in response to ocean acidification
Posted on EPOCA: 11 Aug 2011 The global acidification of the earth’s oceans is predicted to impact biodiversity via physiological effects impacting growth, survival, reproduction, and immunology, leading to changes in species abundances and global distributions. However, the degree to which these changes will play out critically depends on the
