This post summarizes field activities to assess growth and survival of oyster outplants at Westcott Shellfish on San Juan Island.

Field Work

Today Grace L. and I assessed growth and survival and maintained outplants at Westcott. Here are the things that we did:

• Clean all bags
• Download and clean all temperature loggers
• Take images of all oysters for size analysis
• Manually measured length, width, and depth of n=10 oysters per bag for volume models
• Counted the number of dead oysters per bag

We processed 32 total bags today. There were no missing bags and no issues to note.

Grace will return in about a month to move oysters into larger mesh bags.

All images of data sheets and temperature logger files have been uploaded to GitHub here.

Here are some field pictures from today.

Temperature loggers

I downloaded and ran temperature data for the Westcott site. Here are the temperatures from this deployment.
