Assembled gear to deploy oyster biological indicators. Cages will hold the oysters and will be suspended 0.5 meters above the bottom by the buoys and anchored by the bricks.
Cages for deploying oyster biological indicators
These oyster biological indicators were collected after deployment in a tributary of Monie Bay. One set had a greenish tinge, while the other did not, even though both sets were deployed at the same site.
Collected oysters
The oysters in this cage are being deployed as biological indicators of nitrogen source. They will be suspended 0.5 meters above the bottom by the white buoy.

Some cages became very fouled with algae and bryozoans during deployment while others did not. These two cages were deployed at the same location during the same time period.
Fouling of cages for oyster biological indicators
Cages for oyster biological indicators are messy with sediment and fouling after deployment
