Maine Growing Area Closures: Shellfish Area Inventory with Legal Notices and Maps

The DMR Bureau of Public Health Shellfish Closure Map and Data Portal has bacterial (NSSP) classifications, municipal conservation closures, biotoxin closures, and emergency closures displayed. Other layers including P90 scores can be turned on in the layer list.

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.

The Bureau of Public Health oversees the the National Shellfish Sanitation Program (NSSP) within Maine in order to keep molluscan shellfish safe for human consumption.

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.

Provides a comprehensive resource to help managers at the local and state level sustain Maine’s valuable shellfish resources. Includes information on the history and biology of the soft-shell clam, northern quahog, American and European oysters, and blue mussels. There are sections on state resources to address water quality issues and predatory species and tools that municipalities can use to preserve or increase their intertidal shellfish resources.

This book was designed with Certified Shellfish Dealers in mind and gives detailed information about HACCP Plans (Hazard Analysis Critical Control Point), monitoring of Daily Sanitation practices, SSOP (Sanitation Standard Operating Procedures), Tags, Tagging & Transportation of Shellstock, Wet Storage Standard Operating Procedure, and more.

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.

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.

List of all forms used by the Bureau of Public Health.

Lists all forms involved with the annual shellfish management review and forms for municipal activities such as shellfish program deadlines.

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.

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.

Evaluates all shellfish growing areas in the state of Maine to determine their suitability for harvest by conducting a "sanitary survey," which is a three-fold process.

Uses the standards outlined by the National Shellfish Sanitation Program (NSSP) to evaluate and certify all wholesale shellfish dealers in Maine to ship, or process shellfish for shipment, within and outside of the state.

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?

Lists all forms involved with sanitation and the HACCP guidelines including vibrio control plans, wet storage, daily sanitation reports, a processing log with sales records, shipping temperature compliance, and more.

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.
