Fact sheet outlining USDA loan programs, maximum loan amounts, rates, terms, and use of proceeds.

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.

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.

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.

Facilitating economic growth for Maine's farmed shellfish businesses. This project has produced two data-driven, quantitative market assessments to inform industry leaders and business owners about the potential scale and scope of markets for farmed shellfish and to facilitate strategic growth in the industry. The most recent report was completed in 2023 and published in 2024.

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.

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.

These risk management tools are designed to help Maine aquaculture producers find new ways to identify and respond to risk on their farms and in their businesses. The tools include information and visuals to help farmers identify risk factors and risk management within each of the five categories of risk as well as aquaculture crop insurance options currently available.

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.

This guide was created to help the emerging seaweed industry understand the prevailing regulatory requirements surrounding the production of seaweeds as food. There are currently two regulations that are being used to regulate seaweeds at either the federal or state level: the Current Good Manufacturing Practice, Hazard Analysis, and Risk-Based Preventive Controls for Human Food (GMP/PCHF) regulation and the Seafood Hazard Analysis Critical Control Point regulation. This guide will help the reader understand the similarities and differences between the two regulations and help the reader understand how their operation might be regulated.

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.

Guidance on the five steps to form an LLC; chose a name, find a registered agent, file certificate of formation, create an operating agreement, and get an EIN.

A critical long-term decision aquaculturists must make is to determine whether the business can generate enough value over time to pay off its debts. The appropriate financial statement for doing this is the balance sheet. The balance sheet is divided into two main categories: assets and liabilities. The balance sheet is structured by dividing assets and liabilities into one of two time periods: current and noncurrent. This publication, written by Dr. Carole Engle, a specialist in aquaculture economics, will help you identify the financial strengths and weaknesses of your business using balance sheets.

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.

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

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.
