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.

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.

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.

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.

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.

The goal of these new requirements is to control the safety of molluscan shellfish for human consumption by preventing unnecessary growth of bacterial pathogens resulting from improper or ineffective cooling or from time to temperature abuse.

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.

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?

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.

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.

ShellGIS is a desktop-based software tool that, for the choice of 14-commonly cultured shellfish species, enables dynamic predictions of shellfish production, environmental effects, and profitability according to culture practice and site selection within a given GIS domain.

Designed to provide the public, applicants, and leaseholders with useful and accurate information about marine aquaculture in Maine.

Lists contact information for DMR’s aquaculture program staff who are located in Augusta and the Boothbay Harbor Lab.

This workbook is designed to help municipal shellfish committees apply for limited purpose aquaculture permits (LPA). These permits are required for various conservation projects, particularly focused on reseeding or revitalizing wild spawning. It was created collaboratively, with members of the DMR, various municipal shellfish committees, and others working to provide materials and input on the final product.
