The Aquaculture License is now required in order to harvest and sell cultured organisms removed from an aquaculture lease or LPA license site. Aquaculture leaseholders and Limited-Purpose Aquaculture (LPA) license holders are required to obtain the Aquaculture License, regardless of which species they grow.

Reviews upwelling techniques for growing juvenile shellfish including different design considerations pros and cons and locations.

This document is intended to help Maine restaurant owners and staff understand the risks of handling shellfish, and how to manage them safely and effectively.

The Bureau of Public Health oversees the the National Shellfish Sanitation Program (NSSP) within Maine in order to keep molluscan shellfish safe for human consumption.

Licenses AND Sanitation Certificates must be applied for online! This is new and the preferred system for applications now. This includes Shellstock Shipper Certificate, Shucker-Packer Certificate, Shellfish Reshipper Certificate, and Depuration Processor Certificate.

Provides a comprehensive resource to help managers at the local and state level sustain Maine’s valuable shellfish resources. Includes information on the history and biology of the soft-shell clam, northern quahog, American and European oysters, and blue mussels. There are sections on state resources to address water quality issues and predatory species and tools that municipalities can use to preserve or increase their intertidal shellfish resources.

This book was designed with Certified Shellfish Dealers in mind and gives detailed information about HACCP Plans (Hazard Analysis Critical Control Point), monitoring of Daily Sanitation practices, SSOP (Sanitation Standard Operating Procedures), Tags, Tagging & Transportation of Shellstock, Wet Storage Standard Operating Procedure, and more.

Powerpoint on biofouling including, economic impact, general impact, common fouling organisms (macroalgae, tunicates, hydroids, boring sponge, over-set of barnacles, mussels, or oysters), controlling fouling, and methods to avoid, mitigate, or prevent the effects of biofouling.

Presentation on oyster pathogens and diseases such as MSX, SSO, dermo, and Vibrio, testing protocols, long-term management, oyster predators & pests, the difference bewteen infection and disease, disese prevention, biosecurity, risk evaluation, pathogen surveillance, and zonation.

This fact sheet reviews the method for constructing a cylindrical silo for an upwelling system.

Focuses primarily on the environmental sustainability of shellfish aquaculture including resource enhancement, habitat restoration, eutrophication, the impacts of farms on water quality, and harvest methods.

List of all forms used by the Bureau of Public Health.

Lists all forms involved with the annual shellfish management review and forms for municipal activities such as shellfish program deadlines.

There are several ways in which birds interact with shellfish aquaculture. Birds can cause significant damage to crops through predation. Some birds fall into the category of protected resources and farmers have been variously accused of interfering with foraging, (either attracting or disturbing or both) and interfering with hunting. Birds can be attracted to aquaculture structures for roosting or foraging and their guano can impact water quality and trigger the need for growers to develop management plans under the National Shellfish Sanitation Plan.

After purchasing used shellfish production equipment, it is strongly recommended to thoroughly clean and disinfect the gear prior to use to limit the risk of introducing disease or invasive species. An easy-to-use process is as follows:

DMR-approved hatchery status is contingent upon a variety of factors including clean pathology reports and hatchery inspections. Given this, the list below is subject to change.

Facilitating economic growth for Maine's farmed shellfish businesses. This project has produced two data-driven, quantitative market assessments to inform industry leaders and business owners about the potential scale and scope of markets for farmed shellfish and to facilitate strategic growth in the industry. The most recent report was completed in 2023 and published in 2024.
