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.

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.

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.

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.
