Oyster Monitoring Metrics

Two thick metal rakes are lifting a cluster of oysters out of the water.

FWRI biologists conduct monthly, quarterly, and semi-annual monitoring trips to field sites to monitor oyster populations. Each monitoring project will choose metrics that help to assess as specific goal. There are numerous methods manuals available. We provide an overview here, but more detailed information about other monitoring metrics happening throughout the state can be found in the Oyster Integrated Mapping and Monitoring Program Report.
