The Bigelow Laboratory of Ocean Sciences, in collaboration with the Maine Department of Marine Resources, is developing a weekly, site-specific forecast for paralytic shellfish poison (PSP) levels. This forecast is experimental and represents ongoing research, and its predicted toxicity ranges are not representations of fact or guarantees of future toxicity levels. The reader is cautioned not to place undue reliance on forecasts.

A list that contains the names of markets and restaurants that are licensed to purchase shellfish directly from harvesters, then sell them in the retail trade only.

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

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?

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.

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.

The goal of a Vibrio Control or Vibrio Management Plan 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.

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.

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

Uses the standards outlined in the National Shellfish Sanitation Program (NSSP) to monitor levels of PSP (“Red Tide”) and other marine biotoxins in the shellfish of the State of Maine.

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.

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.

The Maine Department of Marine Resources' online licensing and landings system, called LEEDS (Licensing Enforcement and Environmental Data System) is now available. In order to apply for a new license or renew a license with the system, you first need to create a login for LEEDS

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.

Reviews the types of harmful phytoplankton that produce biotoxins such as Alexandrium, which causes paralytic shellfish poisoning; Pseudo-nitzschia, which causes amnesic shellfish poisoning; and Dinophysis, which causes diarrhetic shellfish poisoning.
