Resources Database

Overview of popular finfish and shellfish aquaculture systems (husbandry & gear) used in the northeast including bottom culture, near bottom culture, water column culture, surface culture, hatchery land-based systems.

Overview of mussel farming systems, mussel spat collection, seed stripping and stocking, problems occasionally encountered, processing, packaging and shipping, site selection, and planning a business.

Reviews the importance of recording growth and environmental data, estimating number of seed, and provides template data sheets to record this information.

Fact sheet on aquaculture lease hearings which are an adjudicatory hearing. It also includes the criteria for issuing aquaculture leases.

DMR welcomes and encourages comment on aquaculture lease applications. This explains the process, scoping sessions, submitting a comment, speaking at a public hearing and more.

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.

Answers questions like "What can I grow?", "How much space can I occupy?" "How long does a lease or license last?", "How much will it cost?", "What type of gear can I use?", and more.

A brief introduction to current commercial production species, potential commercial species, and experimental species including the hard clam (quahog), eastern oyster, blue mussel, softshell clam, macroalgae, bay scallop, European oyster, surf clam, sea scallop, and more.

Descriptions of each aquaculture lease and license type. All applications must be submitted using these forms.

At aquaculture lease hearings, Maine DMR will receive evidence relating to the legal criteria upon which it must base its decision on whether to grant the lease. The criteria for granting a standard or experimental aquaculture lease that the lease must not unreasonably interfere with are listed here.

Brief overview of softshell clam distribution, habitat, life cycle, predators, disease, harvest, marketing, and aquaculture.

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.

Summarizes some simple ways that holders of a valid Maine Aquaculture License can get their shellfish to market.

Lists all upcoming aquaculture public meetings, hearings, and scoping sessions and give the date, time, town and location for them.

Oyster aquaculture, like any agriculture operation, has inherent risks with perils beyond growers’ control. However, coastal waters present challenges for oyster farmers in the form of tropical storms and hurricanes.

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.

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

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.

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.
