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 resources for growers including approved hatcheries, biosecurity, shellfish sanitation, harvest and reporting, and forms.

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.

You need to plan ahead to make sure seed stock is available for the growing season. Without a lead on seed, you could end up missing the entire growing season of your first year.

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.

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.

An overview of oyster production techniques including nursery and husbandry, common gear used, and oyster biology.

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.
