Sampling Pacific oysters at Manchester

Below is a post from Yaamini's Notebook


Today we went out to NOAA's Manchester Facility to sample our oysters before placing them in our ocean acidification system! We collected length and weight information for twenty oysters, and extracted adductor, ctenidia (gill), mantle and gonad tissues. Gonad tissue was put in histology cassettes and then placed in fixatives.

Here are some photos from our time at Manchester!

We layed out each oyster to weigh, measure and extract tissue. oyster organization

Some of the oysters were so large we had to hammer them open. hammer

Once open, we extracted four tissue types. Then we removed the body and reweighed the empty shell. shucked oyster

These are the histology cassettes we used to hold gonad samples. Pictured here are the samples for the Olympia oysters. The Pacific oyster samples were tissue pieces, as opposed to the whole gonad. histology cassette

Overall it was an extremely productive day! We'll be back out on Feb. 8 to set up the ocean acidification system.
