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:

To receive the weekly results of the oyster spat surveys, call 1-888-831-5801 or 1-902-831-5801.

View historical and current water temperatures collected at PEI mussel and oyster monitoring sites using the Water Temperature Visualization Tool.

There are two graphing tools; users can either select one site with multiple years of temperature data (top graph) or select one year with multiple sites (bottom graph).
