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.

Focuses primarily on the environmental sustainability of shellfish aquaculture including resource enhancement, habitat restoration, eutrophication, the impacts of farms on water quality, and harvest methods.

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 brochure explains the benefits of shellfish aquaculture for the environment including improving water quality, increasing species diversity, removing excess nitrogen, and not needing fertilizers, chemicals, or antibiotics.

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.

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.

Displays location and information on aquaculture leases and licenses in Maine along with NSSP water quality information and p90 scores, LPA Health Zones, IFW Essential Habitat Boundaries, historic eelgrass data, conserved land information, and low tide imagery.

ShellGIS is a desktop-based software tool that, for the choice of 14-commonly cultured shellfish species, enables dynamic predictions of shellfish production, environmental effects, and profitability according to culture practice and site selection within a given GIS domain.

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

This web-based, report-centric tool provides coastal and ocean planners with a high-level analysis for their custom-drawn area of interest. It provides summary statistics and infographics for six main topics: general information, energy and minerals, natural resources and conservation, oceanographic and biophysical, transportation and infrastructure, and economics and commerce.

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

The aim of this open access book is to review and analyze the goods and services of bivalve shellfish.

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