List of the over 200 harbor masters and deputy harbor masters in The State of Maine Harbor Masters Association.

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.

You need to plan ahead to make sure seed stock is available for the growing season. Without a lead on seed, you could end up missing the entire growing season of your first year.

Developing oceanographic models of factors that control the productivity of Maine's coastal waters in three bioregions (southern, central, and down east Maine), supplemented by hourly monitoring of biophysical parameters in 6 coastal regions through LOBO buoys in the more sheltered waters, and at the mouths of the bays in more exposed conditions using buoys developed at the University of Maine. The SEANET buoy network is supplemented with other smaller buoys and sensors involving students, citizen monitors, fishermen, and aquaculturists.

Uses an individual growth model over 30 days for Eastern Oyster, Blue Mussel, and European Oysters using satellite inputs for temperature, chlorophyll, and particulate organic matter to determine locations where they will grow best.

Maine aquaculture marking requirements (effective January 1, 2023) for lease sites and LPA sites with a sample marker buoy image.

All wild shellfish stock or seed used for cultivation or grow-out must originate from within the same Limited Purpose Aquaculture (LPA) license Health Zone as the LPA license site. A permit is required from DMR if the stock or seed originates from outside the Health Zone.

Displays location and information on aquaculture leases and licenses in Maine along with NSSP water quality information and p90 scores, LPA Health Zones, IFW Essential Habitat Boundaries, historic eelgrass data, conserved land information, and low tide imagery.

This training program uses a mix of meetings and field trips/site visits to introduce participants to the issues important in running a successful aquaculture business including: site selection, equipment and husbandry, permitting and regulation, environmental monitoring, marketing and sales, farm management and biosecurity, business planning, and financial management.

Established in 1988 by the Maine Legislature with a mission to assist in developing economically and environmentally sustainable aquaculture opportunities in Maine.

The “Clam Kit” video series shares techniques developed at Downeast Institute to help municipal shellfish management programs enhance their softshell clam flats affordably and effectively. This video gives an overview of clam seed, DEI's hatchery, floating nursery trays, public stock enhancement, DMR lease or LPA, basic husbandry, overwintering, and more.

Supporting marine science for Maine people focusing on Maine’s coastal communities, scientific research, and tomorrow's marine workforce.

Thesis paper explaining the work that went into creating the Oyster suitability Index.

In depth review of sea scallop biology, spat collection, nursery, grow out, gear, husbandry, site selection economic considerations and biotoxins/public health.

An overview of oyster production techniques including nursery and husbandry, common gear used, and oyster biology.

This report is based on the research priorities survey conducted in June 2019 of Maine’s aquaculture community and is compared with surveys from 2012 and 2016 to look at trends. There have been some changes in the prioritization of needs since 2016, but many of the same research, development, and education (R&D&E) needs persist and remain unaddressed. As expected, there are different R&D&E priorities for different aquaculture sectors.

The Coastal Satellite Oceanography team at University of Maine created a high resolution satellite imagery of the coast of Maine that uses sea surface temperature, turbidity, and chlorophyll concentration to determine oyster suitability.

Detailed look into why site selection is so important including, biological requirements, physical characteristics, as well as social & regulatory factors.

Provides a summary of direct and indirect environmental factors that may affect your site selection for your marine aquaculture business.
