View Oyster Monitoring Results

The Oyster Monitoring Program (OMP) is a technical service provided to oyster growers since 2001. The OMP primarily serves to provide information on spat-fall prediction to oyster farmers to assist them in determining when to deploy their spat collectors. This is accomplished through the monitoring of the number and size of oyster larvae in water samples collected from various sites throughout the province. This information is collected between June and August every year.

You can receive the weekly results of the oyster spat surveys by telephone recording or on this website:
