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.

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.

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.

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

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.

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

List of all forms including a field data collection sheet, MOU for non-private and private lab biotoxin testing and analysis, industry biotoxin sample protocol, guidance for high risk areas and species, and a private lab analysis table.

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.

This training program uses a mix of meetings and field trips/site visits to introduce participants to the issues important in running a successful aquaculture business including: site selection, equipment and husbandry, permitting and regulation, environmental monitoring, marketing and sales, farm management and biosecurity, business planning, and financial management.

Established in 1988 by the Maine Legislature with a mission to assist in developing economically and environmentally sustainable aquaculture opportunities in Maine.

If you have been around this business for a while, you’ve probably watched some of the newcomers make the same mistakes you did when you were getting started. ECSGA Executive Director Bob Rheault decided he would try to think of as many of these common pitfalls as he could to help new growers avoid making the same costly blunders. Through the years he has continued to add to the list.

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.

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.

Free online boating safety course that is recognized by the U.S. Coast Guard, approved by NASBLA and the Maine state boating license agency. Complete the course in three steps: enroll in a Boating Safety Course from the course catalog, study and pass the free Boating Safety Course, and print out your certificate of completion.

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.

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.
