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.

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.

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 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.
