Summer 2024 outplanting overview
Overview of hardening efforts and stocks
We are going to outplant oysters at with commercial partners from efforts B, D, and E.
Effort B: 2023 POGS seed daily hardening
| Treatment | Number of Animals | Approx. Size | Current location | Identifiers | Number Bags | Animals per bag | Outplant location | Notes |
|---|---|---|---|---|---|---|---|---|
| Temperature treated | 250 | 10-25 mm | Point Whitney | “POGS daily seed; silos; right tank” & “POGS seed bags #3 and #4” | 5 | 50 | Westcott | Size >12 mm |
| Control | 250 | 10-25 mm | Point Whitney | “POGS daily seed; silos; middle tank” & “POGS seed bags #1 and #2” | 5 | 50 | Westcott | Size >12 mm |
Animals too small (<12 mm or close to 12 mm in length and/or width) kept in original bags at Point Whitney. These can be used for survivorship curve testing or sampling.
Effort D: 2023 POGS small seed weekly hardening
| Treatment | Number of Animals | Approx. Size | Current location | Identifiers | Number Bags | Animals per bag | Outplant location | Notes |
|---|---|---|---|---|---|---|---|---|
| Temperature treated (Tray 1) | 600 | 15-30mm | Point Whitney | Outdoor trays | 6 | 100 | Westcott | |
| Control (Tray 2) | 600 | 15-30mm | Point Whitney | Outdoor trays | 6 | 100 | Westcott | |
| Temperature treated (Tray 3) | 500 | 15-30mm | Point Whitney | Outdoor trays | 5 | 100 | Westcott | |
| Control (Tray 4) | 500 | 15-30mm | Point Whitney | Outdoor trays | 5 | 100 | Westcott |
Animals left over (small size or extras) kept in original trays at Point Whitney. These can be used for survivorship curve testing or sampling.
Effort E: 2023 POGS large seed weekly hardening
| Treatment | Number of Animals | Approx. Size | Current location | Identifiers | Number Bags | Animals per bag | Outplant location | Notes |
|---|---|---|---|---|---|---|---|---|
| Temperature treated | 400 | 18-35mm | Point Whitney | Outdoor trays (“large POGS”) | 4 | 100 | Goose Point | Can increase density if more available |
| Control (temperature tray) | 300 | 18-35mm | Point Whitney | Outdoor trays (“large POGS”) | 3 | 100 | Goose Point | Can increase density if more available |
| Fresh treated | 400 | 14-30mm | Point Whitney | Outdoor trays (“large POGS”) | 4 | 100 | Goose Point | Can increase density if more available |
| Control (fresh tray) | 300 | 14-30mm | Point Whitney | Outdoor trays (“large POGS”) | 3 | 100 | Goose Point | Can increase density if more available |
Totals
| Site | Effort B Bags | Effort D Bags | Effort E Bags | TOTAL |
|---|---|---|---|---|
| Westcott | 10 | 22 | 0 | 32 |
| Goose Point | 0 | 0 | 14 | 14 |
Total animals outplanted at Westcott = 2,700
Total animals outplanted at Goose Point (expected): 1,400
