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

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

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.

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.

This directory aims to identify available sources of seaweed (macroalgae) seed for cultivation in the United States. The directory includes facility contact information, available species, and other factors related to seaweed seed sources. Updated annually, this directory will serve as a valuable resource to current and prospective farmers, regulatory authorities, and researchers across the country. Please note, this directory only reflects facilities that have chosen to opt-in, and therefore, is not a complete list of all sources.

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.

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.

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.

You need to plan ahead to make sure seed stock is available for the growing season. Without a lead on seed, you could end up missing the entire growing season of your first year.

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.

All wild shellfish stock or seed used for cultivation or grow-out must originate from within the same Limited Purpose Aquaculture (LPA) license Health Zone as the LPA license site. A permit is required from DMR if the stock or seed originates from outside the Health Zone.

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.

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.

Providing and promoting lifelong education and learning opportunities for students and professionals, the Algae Foundation seeks to demystify algae by providing unique Algae Academy education modules to bring algae into the classroom, collegiate level courses to prepare the next generation of bioeconomy professionals, and teacher trainings to enhance the science capabilities of our educators.

The Maine Seaweed Exchange is a 501(c)(3) non-profit organization dedicated to advancing the success of seaweed professionals of any experience level. We provide education, advocacy, and access to a network of thoughtful and dedicated members from around the world.
