The Aquaculture License is now required in order to harvest and sell cultured organisms removed from an aquaculture lease or LPA license site. Aquaculture leaseholders and Limited-Purpose Aquaculture (LPA) license holders are required to obtain the Aquaculture License, regardless of which species they grow.

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

This document is intended to help Maine restaurant owners and staff understand the risks of handling shellfish, and how to manage them safely and effectively.

Licenses AND Sanitation Certificates must be applied for online! This is new and the preferred system for applications now. This includes Shellstock Shipper Certificate, Shucker-Packer Certificate, Shellfish Reshipper Certificate, and Depuration Processor Certificate.

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.

A data-driven, quantitative market assessment that informs industry leaders and business owners about the potential scale and scope of markets for farmed shellfish and to facilitate strategic growth in the industry.

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

List all interstate certified shippers that can ship fresh and frozen oysters, clams, mussels, whole or roe-on scallops and is published monthly.

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.

Slideshow summarizing the regulations for shellstock and shucked shellfish handling, sanitation, tagging, and labeling for the state of Maine

This brochure reviews what Vibrio is and how to reduce illness from Vibrio by achieving and maintaining temperature controls when harvesting and transporting shellfish.

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.

The goal of these new requirements is to control the safety of molluscan shellfish for human consumption by preventing unnecessary growth of bacterial pathogens resulting from improper or ineffective cooling or from time to temperature abuse.

A basic list of what licenses you need to sell your aquaculture shellfish at your home, at your lease site, to your local grocery/general store, roadside, to a restaurant, to a wholesale distributor, at a farmers market, or out of state.

This flowchart maps the different licenses you need to have to sell your aquaculture shellfish out of state by mail or by vehicle, and in the state of Maine including selling direct to restaurants, and wholesale distributors, at a farmer's market, your home, and your lease site.

Answers basic questions about Maine DMR's Aquaculture Harvest License such as: Who should have it?, What is it? What does it cost?, What does this license allow you to do?, How do I apply?, and Who should I contact with questions?

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.

This brochure reviews safe handling, storage, and cooking practices that shellfish consumers should follow to prevent illness.
