The major consumptive fisheries in the PIE-Rivers region take place in the estuarine portion of the watersheds. The most important of these fisheries is the harvest of bivalve shellfish, including soft-shelled clams. The MA Division of Marine Fisheries and local municipalities manage the fisheries and must close some areas to harvest due to human health risk. These closures are problematic from an economic and social standpoint and are also indicative of watershed scale issues including pollution and stormwater runoff.

Availability: PIE                  Frequency: Annual

  • Shellfish permanently closed areas – portions of the PIE-Rivers estuary that are permanently (all year) closed to shellfish harvest for human consumption regardless of weather or water testing results

Response Variable(s): Closed area (acres) – change over time

  • Shellfish temporarily closed areas (rainfall) – Shellfish harvest areas that close periodically based on rainfall and water quality data collected by MA Division of Marine Fisheries.

Response Variable(s): Closed area (acres) – change over time

  • Shellfish temporary closures (rainfall) – Number of days per year that temporarily closed areas are closed in response to rainfall events.

Response Variable(s): Days Closed (count)
