Summarizes common and important mistakes that new growers will make when first starting.

A variety of tenacious myths critical of marine aquaculture practiced in the United States have persisted for decades to be presented as facts to the public and Congress. The reality is U.S. fish and shellfish farmers culture aquatic animals and plants within a very complicated and expensive legal, regulatory, husbandry, and science-driven environment. We believe critics are unfamiliar with this environment or have erroneously assumed marine aquaculture-related environmental damage reported in other countries occurs in the United States.

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.

A study to provide an up-to-date and accurate annual statewide economic contribution of Maine’s aquaculture industry and determine aquaculture business owner and farm demographics.

This brochure explains the benefits of eating locally farmed seafood including freshness, heart-health, food safety, good nutrition, and community benefits.

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:

Reviews the benefits of developing a biosecurity plan and a step-by-step outline on how to develop a plan that will protect your farm from disease-causing organisms or pathogens.

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.

An ID guide to organisms commonly found in, on, and around oyster grow bags ​and other aquaculture equipment used in the Gulf of Maine and North Atlantic.

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.

List of the over 200 harbor masters and deputy harbor masters in The State of Maine Harbor Masters Association.

This report addresses biofouling management in relation to marine aquaculture industry operations, equipment and infrastructure. It covers shellfish, finfish and seaweed operations in estuaries and seawater. It does not address freshwater aquaculture activities.

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

Social license to operate (SLO), a concept that describes community acceptance and approval of incoming industry, offers a lens for better understanding these barriers and an opportunity to identify strategies for successful development. Efforts to measure and predict social license have begun, but these efforts primarily focus on company actions and impacts. This study seeks to expand the utility of social license within the aquaculture sector by developing a preliminary quantitative framework that can predict a community’s willingness to issue SLO prior to siting.

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

Free online courses in macroalgae cultivation, microalgae cultivation, introduction to algae, and algae biotechnology. Created out of a partnership between academic institutions, national research laboratories, and industry leaders, ATEC’s goal is to develop novel educational programs to strengthen industry workforce capabilities, by focusing on the skills needed to support the commercialization of algal products. Through algal education, students learn practical applications of farming and biotechnology developing the skills for the next generation of algal-based jobs.

This directory is intended to identify shellfish hatcheries and nurseries from along the east coast of the United States in order to serve as a tool for providing a stronger link between shellfish seed suppliers and shellfish farmers. The directory includes contact information for each business, as well as some additional information indicating the type of operation (i.e., hatchery, nursery, or research) and what products they expect to have available.

UC Davis Aquaculture visits Dr. Julieta Martinelli at the University of Washington, Seattle, to learn about the shell-boring marine worm polychaete, otherwise known as blister worms (Polydora websteri), and the treatments to control them in oyster shellfish aquaculture farms.

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.

If you have been around this business for a while, you’ve probably watched some of the newcomers make the same mistakes you did when you were getting started. ECSGA Executive Director Bob Rheault decided he would try to think of as many of these common pitfalls as he could to help new growers avoid making the same costly blunders. Through the years he has continued to add to the list.

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.

A look at the individual Maine farmers who make a living in the growing industry of Aquaculture.

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.
