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.

This workbook is designed to help municipal shellfish committees apply for limited purpose aquaculture permits (LPA). These permits are required for various conservation projects, particularly focused on reseeding or revitalizing wild spawning. It was created collaboratively, with members of the DMR, various municipal shellfish committees, and others working to provide materials and input on the final product.

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.

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 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

The council consists of 5 members make recommendations to the commissioner concerning expenditures from the Aquaculture Management Fund.

All holders of aquaculture leases and LPA licenses are required to hold the Aquaculture Harvest License in order to harvest and sell product from their aquaculture sites, regardless of the species they grow. Commercial harvester's licenses now apply to only wild-harvest product.

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.

Webinar about research on scallop aquaculture production and economics including comparisons of nursery and growout gear: lantern nets, pearl nets, ear hanging, pocket nets, rigid trays, and adhesives; tissue sampling and testing for biotoxins such as saxitoxin and domoic acid; evaluation of fouling communities; surveys of producers to understand economic inputs and outputs such as capital, labor, and yield; environmental data matched with growth data to better understand good scallop-farming sites.

As part of the Scallop Research Collaborative, we're creating a public database of scallop research happening throughout the state of Maine. Our goal is to create a resource that brings together research in both wild harvest and aquaculture scallops, to increase transparency and communication about research, and to create new opportunities for collaboration.

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.

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.

This DMR pages includes Pre-application Meeting And Scoping Session Guidance Documents, Non-Discharge Aquaculture Application form, Discharge/Finfish Aquaculture Application form, Riparian List form, Corporate Applicant Information Document, and Standard Lease Laws and Regulations.

DMR welcomes and encourages comment on aquaculture lease applications. This explains the process, scoping sessions, submitting a comment, speaking at a public hearing and more.

In depth review of sea scallop biology, spat collection, nursery, grow out, gear, husbandry, site selection economic considerations and biotoxins/public health.

This report is based on the research priorities survey conducted in June 2019 of Maine’s aquaculture community and is compared with surveys from 2012 and 2016 to look at trends. There have been some changes in the prioritization of needs since 2016, but many of the same research, development, and education (R&D&E) needs persist and remain unaddressed. As expected, there are different R&D&E priorities for different aquaculture sectors.
