Resources Database

Comprehensive information on aquaculture leases and Limited-Purpose Aquaculture (LPA) licenses, including details on active and denied lease decisions, pending applications, and interactive data tables with links to maps and documents.

DMR resources for growers including approved hatcheries, biosecurity, shellfish sanitation, harvest and reporting, and forms.

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.

A study to provide an up-to-date and accurate annual statewide economic contribution of Maine’s aquaculture industry and determine aquaculture business owner and farm demographics.

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:

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

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.

Webinar about research on scallop aquaculture production and economics including comparisons of nursery and growout gear: lantern nets, pearl nets, ear hanging, pocket nets, rigid trays, and adhesives; tissue sampling and testing for biotoxins such as saxitoxin and domoic acid; evaluation of fouling communities; surveys of producers to understand economic inputs and outputs such as capital, labor, and yield; environmental data matched with growth data to better understand good scallop-farming sites.

Provides the essential skills, knowledge and confidence to survive potentially life-threatening situations using both classroom and hands on training in the use of lifesaving equipment.

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