DMR undertakes the programs below to monitor the effects of disease on marine organisms.
Oyster Disease Monitoring
DMR conducts an annual screening of American oysters for major diseases that have been shown to result in high mortality in oysters. We select both wild and farmed oysters to screen for these diseases. Aquaculture lease and LPA license holders are invited to submit samples which DMR screens for the diseases. The results are provided, free of charge, directly to the lease or LPA license holder. The results will also be published anonymously on the Regional Shellfish Seed Biosecurity Disease map published by Rutgers University.
This is an opportunity to gauge the general health of Maine's American oyster stocks, and to support science-based best management practices.

Net Pen Salmon Aquaculture Biosecurity Monitoring
Infectious salmon anemia virus (ISAV) is an internationally regulated pathogen of salmon because of its potential for high virulence and transmissibility. ISAV does not affect humans or other mammals. Although the virus is not exotic to Maine coastal waters, DMR has kept the virus on its list of “Exotic” pathogens of regulatory concern due to its limited distribution and due to its potential to harm Atlantic salmon interests of the State.
All marine salmon net pen aquaculture sites located within the coastal waters of the State of Maine are subject to monthly surveillance and reporting requirements outlined in DMR chapter 24.
In addition, all vessels, service equipment and net pens involved in aquaculture activities are required to undergo an initial biosecurity audit as well as timely follow-ups if needed to verify compliance with the initial audit’s findings.
The movement of vessels and equipment used in farming Atlantic Salmon is also restricted, and the movement of vessels or equipment between the areas of Machias, Cobscook, and Jonesport must be reported.
