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.

Reviews the importance of recording growth and environmental data, estimating number of seed, and provides template data sheets to record this information.

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.

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 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.

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.

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.

A brief introduction to current commercial production species, potential commercial species, and experimental species including the hard clam (quahog), eastern oyster, blue mussel, softshell clam, macroalgae, bay scallop, European oyster, surf clam, sea scallop, and more.

The report provides information on commercially relevant aspects of oyster production gear associated with each equipment type employed including, BST™ Crosshatch, BST™ Longline, OysterGro, Rack and Bag, & Seapa™. They tracked oyster survival, growth by season, shell morphology, worm presence, and cost estimates.

The Sea Grant network has established a National Seaweed Hub to serve as a science-based, non-advocacy resource for the domestic seaweed and seaweed aquaculture industry. This collaboration provides a framework to share information, address challenges, identify needs, and find opportunities in this emerging industry.

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.

If you're thinking about farming mussels, either as a sideline or the main chance, this booklet is designed to help you make decisions.This booklet reviews mussel raft culture in the Gulf of Maine, The Mussel Raft Project, Predators, storms and moorings, Mussel biology, Selecting a site, Steps in culturing mussels, Outreach, applied research, Sales and marketing , Getting into business, Planning a mussel business, Training and information, Leases and permits, Suppliers, and provides further reading suggestions.

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.

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.
