[Oyster_seed_group] August 23, 2011 Willapa Oyster Bulletin

From Alan Trimble

Hello Everyone,
Samples from yesterday morning’s high water did not contain
any remaining Pacific Oyster larvae from the August 3 cohort.
However, the new cohort we detected on Sunday evening were
present throughout the samples. They have grown to early umbo
at 100 microns in 2 days. The unsettled weather of yesterday
may be a factor in survival – we will sample again tomorrow.

Here are the counts (per 20 gallons.)
