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.

Research paper on mussel spawning, spat (seed) collection, and hatchery grow out. They researched naturally and artificially conditioned mussel broodstock; compare different ropes used for settling larvae; hatchery production methods; if differences exist in growth and retention rates; whether working mussel farms would benefit from multiple cohorts of cultured seed; & the effectiveness of remote vs. traditional setting methods to decrease costs associated with the production of cultured mussel seed.

A critical study that describes the growth potential for Maine's edible seaweed market over the next fifteen years. This report documents the size and nature of the business opportunity and identifies the requirements for sustainable growth.

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.
