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.

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.

A data-driven, quantitative market assessment that informs industry leaders and business owners about the potential scale and scope of markets for farmed shellfish and to facilitate strategic growth in the industry.

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.

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?

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.

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.

This report provides an overview of permitting and leasing programs for aquaculture in U.S. state waters. However, it is strongly recommended that you speak with a local aquaculture representative prior to beginning your planning process. Aquaculture permitting is both complex and subject to frequent change.

Details the specific regulations, contacts, information sources and production estimates for each of the 22 coastal states.

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.

The report provides information on commercially relevant aspects of oyster production gear associated with each equipment type employed including, BST™ Crosshatch, BST™ Longline, OysterGro, Rack and Bag, & Seapa™. They tracked oyster survival, growth by season, shell morphology, worm presence, and cost estimates.

This web-based, report-centric tool provides coastal and ocean planners with a high-level analysis for their custom-drawn area of interest. It provides summary statistics and infographics for six main topics: general information, energy and minerals, natural resources and conservation, oceanographic and biophysical, transportation and infrastructure, and economics and commerce.
