Answers basic questions about Maine DMR's Aquaculture Harvest License such as: Who should have it?, What is it? What does it cost?, What does this license allow you to do?, How do I apply?, and Who should I contact with questions?

This brochure reviews what Vibrio is and how to reduce illness from Vibrio by achieving and maintaining temperature controls when harvesting and transporting shellfish.

A list that contains the names of markets and restaurants that are licensed to purchase shellfish directly from harvesters, then sell them in the retail trade only.

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.

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.

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

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.

Intended to help prospective farmers to identify, record, monitor, and manage production hazards, and ultimately minimize production-related risk. Discusses types of risk in aquaculture, record keeping, environmental conditions, biofouling organisms, predators, diseases, parasites, invasive species, and operational procedures.

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.

In September 2023 the ECSGA updated its 2010 Best Management Practices manual. Building on the 2010 version, this update adds a new section on the management and handling of floating gear, hundreds of embedded links, info on new gear types and a revised bibliography. ECSGA also completely revamped the tool to create your own farm-specific Best Practices document: the Best Practices Form.

In depth document created to provide the information and a framework that will enable a shellfish farmer to write a comprehensive Best Management Practices document focusing on gear/operation and maintenance, user conflicts, permitting/siting, and environmental concerns.

Reviews harmful algae blooms including conditions for biotoxin formation, detection, management, and common types of HAB's in the northeast.

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

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

Guidance document for industry that identifies areas DMR has deemed a high biotoxin risk and specific management criteria for safe harvest.

The Maine Department of Marine Resources' online licensing and landings system, called LEEDS (Licensing Enforcement and Environmental Data System) is now available. In order to apply for a new license or renew a license with the system, you first need to create a login for LEEDS

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

Evaluates all shellfish growing areas in the state of Maine to determine their suitability for harvest by conducting a "sanitary survey," which is a three-fold process.

A basic list of what licenses you need to sell your aquaculture shellfish at your home, at your lease site, to your local grocery/general store, roadside, to a restaurant, to a wholesale distributor, at a farmers market, or out of state.

This flowchart maps the different licenses you need to have to sell your aquaculture shellfish out of state by mail or by vehicle, and in the state of Maine including selling direct to restaurants, and wholesale distributors, at a farmer's market, your home, and your lease site.

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.
