Overview

On 10/02 I did our final assessment of the Effort E (fresh water and thermal hardening) seed at Goose Point and closed out this project!

Final assessment

I did the following today to assess and close out the Effort E Goose Point seed experiment:

  • Goose Point collected our cages and brought them to the dock. 1 bag was missing (no. 342; FW treated) and 1 was empty (no. 343; Temp treated). There were 12 in good shape. We had n=5 of FW control, n=2 FW treated, n=3 Temp control, and n=2 Temp treated cages.
  • Removed oysters from each cage and counted mortalities
  • Arranged oysters for a photograph to capture number of live animals and for growth analysis
  • Tag and scale bar included in each photo
  • Subsampled oysters from each bag to total n=~30 oysters per treatment group (4 treatment groups total) into red mesh bags with their own tag labels for survival assays in the lab (see below)
  • Bags and equipment were cleaned
  • Four temperature loggers were downloaded that were brought in on the cages.
  • I recorded data and uploaded size image photos.
  • I will transport oysters to UW on Sunday.
  • I took manual measurements of a subset of oysters for length, width, and depth.

All data is in our oyster hardening seed GitHub repo.

Samples for survival assays

All data is in our hardening seed GitHub repo in the lab survival folder.

Here is a table of the tags collected today from Goose Point I will use this to help Jesse and Maddy prepare datasheets for assays. Each bag has about 30-35 oysters. 30 will be used for collections.

See our methods plan in my previous post here for the survival assays.

tag experiment location treatment
87 Effort E Goose Point FW Control
88 Effort E Goose Point FW Treated
89 Effort E Goose Point Temp Control
90 Effort E Goose Point Temp Treated

To do

  • Start final photo analysis for growth and survival
  • Survival assays in the lab (Jesse & Maddy)
