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.

A guide on what is soft-shell clam farming, how to start your own farm, and quick overview of the financials of clam farming.

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:

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 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.

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.

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.

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.

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.

They provides a wide range of services to facilitate trade between local food suppliers and importers around the world including: export education, self-paced training & expert advice, customized export assistance, new market analysis, international marketing &branding, facilitate meetings with international buyers, and a cost-share funding program.

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

Overview of how Pemaquid Mussel Farms reached their development goal of a 5 fold increase in production within 10 years to $15 million annually using new technology and business planning.

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 assesses the potential market environment for Maine farm-raised sea scallops including political, economic, social, technological, environmental, legal/regulatory, strengths, weaknesses, opportunities, and threats.

In-depth paper on the implementation of the United Nations’ 2030 Agenda for Sustainable Development and its 17 Sustainable Development Goals.

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.

Presentation on what was learned from Japan, the world leaders in scallop aquaculture, including lantern nets, spat bags, grading, washing, and recipes.

As part of an ongoing and productive relationship, a delegation from Maine visited the gear supplier Mutsu Kaden Tokki Co., Ltd. located in Aomori Prefecture, Japan. This video reviews the gear needed for the Japanese scallop aquaculture industry technique called 'ear-hanging'.

A study the researched and inventoried the seasonality, sources, and market utilization of locally produced seafood within the state and help educate food consumers at many different levels about the opportunities for gaining access to Maine seafood.
