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.

This video gives a first-hand account of running a mussel farm by Bangs Island Mussels including on the water gear and husbandry and well as shore-side processing. Some highlights are seeding, socking, hauling and stripping machine, de-clumper, size grader, debyssing machine, automatic bagger/weigher/conveyor, and more.

Reviews the keys to running a successful business; the four P's of marketing, wholesale distributors, risks, and sales.

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.

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.

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.

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.

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.

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.

Reviews business management skills, such as finance, record keeping, marketing, and personnel management. More aquaculture businesses fail because of poor management than poor production practices.

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.

Discusses what marketing is and why it is important including developing a marketing plan, market outlets, and personalizing the products and the business.

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

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.

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
