Reviews upwelling techniques for growing juvenile shellfish including different design considerations pros and cons and locations.

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.

Presentation on oyster pathogens and diseases such as MSX, SSO, dermo, and Vibrio, testing protocols, long-term management, oyster predators & pests, the difference bewteen infection and disease, disese prevention, biosecurity, risk evaluation, pathogen surveillance, and zonation.

This fact sheet reviews the method for constructing a cylindrical silo for an upwelling system.

Represents over 1500 shellfish farmers from Maine to Florida and has many resources for growers including rookie mistakes, marketing, and public health concerns.

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.

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:

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.

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.

Fact sheet designed to try to improve the growers knowledge on the process to contact a professional who can examine dead or dying shellfish to determine the cause and how to get the shellfish to them for analysis.

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.

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.

Construction guide for the Cornell System FLUPSY using off-the-shelf components including instructions, diagrams, and images.

A list of current aquaculture training programs offered in Maine.

The Maine Aquaculture Association has released the first Maine Aquaculture Occupational Standards, which specify the current workforce skills and training needs of Maine’s aquaculture sector. Altogether, four standards have been released, focusing on occupations related to (1) Marine Shellfish and Sea Vegetables; (2) Marine Finfish; (3) Land-Based RAS; and (4) Land-Based Shellfish Hatcheries. A supplementary document, the Maine Shellfish Aquaculture Career Pathways Map, is designed to provide an overview of the most common job types, entry points, and career pathway opportunities in Maine’s shellfish aquaculture sector today.

Provides a unified national voice for aquaculture on the national level as well as informative webinars, publications, and facts about aquaculture.

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

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

A global fish and shellfish health lab, we offer you top-quality diagnostics, import/export inspections, and veterinary solutions from consultation to custom vaccines.

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.

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.

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.

Aquaculture of softshell clams (Mya arenaria), also called “steamer clams”, has grown steadily and is becoming a significant industry in New England. Examined in this fact sheet are specific aspects of softshell clam production during the Hatchery Phase and a description of variations in management practices at three shellfish facilities: two in Massachusetts and one in Maine.
