DV-20-02 A tagging study to understand sea scallop (Placopecten magellanicus) growth and movement in the Lower Penobscot Bay rotational management area

Phoebe Jekielek Hurricane Island Center for Science and Leadership Amber Lisi UMass Dartmouth The sea scallop industry is the third most lucrative marine fishery in the United States and ranked sixth in value in Maine. Management guidelines currently assume that scallops do not move between state and federal management areas. However, recent studies have shown […]

DV-20-04 Are lobster habitats changing as an indirect effect of climate change?

Robert Steneck In Maine, the American lobster (Homarus americanus) fishery is key contributor to Maine’s economy, constituting 76% of all marine resource value and supporting numerous coastal communities. American lobsters primarily inhabit boulder fields. However, warming waters and the presence of invasive algal species, which create anoxic (oxygen-depleted) areas in boulder crevices, may be driving […]

DV-20-03 Linking ecological and social resilience in coastal communities

Eileen Sylvan Johnson Built along the edge of the state, where the land meets the sea, Maine’s coastal communities are uniquely connected to and impacted by the ocean. As extreme weather events, sea level rise, flooding, and storm surges become more severe and push further inland, Maine’s coastal communities experience greater risk and a greater […]

DV-20-05 Quantifying Soft-Shell Clam Fecundity Across Two Regions of the Maine Coast

Brian Beal Soft-shell clams are a culturally important fishery. Yet, over the past 40 years, commercial clam landings have declined by 75%, due in part to declines in standing stock and clam population size based on recent changes in their ecosystems. Predators, such as the invasive green crab (Carcinus maenas) and native milky ribbon worms […]

DV-19-18: New pathogen discovery in wild blue mussels from the Gulf of Maine

Dr. Mikhail Zuykov Laurentian University In August 2019, a pathogenic green algae, Coccomyxa spp. was found in mytilid mussels, Mytilus spp. in Jonesport, Maine and the surrounding area. Previous reports have documented the algae in Canadian coastal provinces and European waters, but this may be the first record of it in the Gulf of Maine. […]

DV-19-16: Aquaculture in Maine Classrooms – Making Connections

Morgan Cuthbert Yarmouth Schools Aquaculture is one of the fastest growing food producing sectors in the world, according to the Food and Agriculture Organization of the United Nations (FAO). In Maine, aquaculture is becoming a prominent industry and is serving as a means for commercial fishermen to diversify their efforts. Furthermore, the National Oceanic and […]

DV-19-19: The Lobster Gangs of Maine in a changing fishery

Dr. Chris Petersen College of the Atlantic According to the Maine Department of Marine Resources, lobster landings have been increasing since 1985, with over 132 million pounds landed in Maine during 2016. The lobster fishery has historically remained viable, even when other local fisheries have not. This is likely the result of the strong conservation […]

DV-19-17: The who, how, and why? A deep dive into understanding Maine’s fishermen-farmers

Caitlin Cleaver, PhD Candidate University of Maine Maine coastal communities depend on the viability of the American lobster (Homarus americanus) fishery. However, as the Gulf of Maine changes, some lobstermen are diversifying their efforts to include oyster, mussel, seaweed, and salmon farming. The objective of this research is to understand the characteristics of fishermen-farmers based […]

DV-19-09 Boat modifications and haulable longlines to improve efficiency and safety in seaweed harvest

Ken Sparta and Rick Milliard Spartan Sea Farms/Hamilton Supply Company Researchers have identified Maine’s coasts as a suitable location for kelp cultivation. Current growing methods include the use of single, submerged longlines on which a seeded line of kelp can be placed. These lines can weigh upwards of 11,000 lbs per 1,000 feet and it […]

DV-19-12 Alternative lobster bait attractant testing

Dr. Steven Jury Saint Joseph’s College of Maine Atlantic herring (Clupea harengus) is the preferred bait for the American lobster (Homarus americanus) fishery. In an effort to increase herring recruitment and spawning stock biomass, the Atlantic States Marine Fisheries Commission has reduced commercial landings, spurring interest in finding and testing alternative bait attractants for the […]
