Each oyster can filter 40 gallons of water per day. An oyster reef can shelter up to 100 other species so they dramatically add to biodiversity. Oysters also sequester nitrogen in wastewater and each person creates 12 pounds per year. Oyster shells contain calcium carbonate a known buffer that can help offset ocean acidification. 

MOP has shown that oysters can survive and grow in Boston Harbor. Where and when we can, we. We also support other programs, such as Wellfleet's oyster propagation zones.


The Osterville Planting Project

Please note that the Osterville program is spreading the oysters for later harvest. The MOP oyster placements are not for harvesting. We are seeking to build self-sustaining populations to improve water quality.


The Gloucester Upweller

We have partnered with Maritime Gloucester on the North Shore to pursue an aquaculture pilot project to place an upweller on Maritime Gloucester’s newly renovated main pier in downtown Gloucester. This exciting educational program to collect water quality data from water entering and exiting the upweller will measure the oysters’ impact on local water pollution. Find out more about upwellers.
