Liposome-based microparticles for improved nutrition and production efficiency of marine fish larvae

Lead PI: Chris Langdon (OSU) PI Email: chris.langdon@oregonstate.edu Co-PI: Matt Hawkyard (UMaine/ARI), Kevin Stuart (HSWRI), Mark Drawbridge (HSWRI) Project Team: UMaine/ARI, Oregon State University, Hubbs-SeaWorld Research Institute, Zeigler Bros. Abstract: Currently available commercial-type microdiets have not been able to eliminate the Need for live feeds in marine finfish hatcheries. This is largely due to 1) low ingestion rates of […]

Sustainable US cleaner fish production: developing a lumpfish broodstock program

Lead PI: Elizabeth Fairchild (UNH) PI Email: elizabeth.fairchild@unh.edu Co-PI: Heather Hamlin, Michael Chambers (UNH), Todd Guerdat (USDA) Project Team: Greg Lambert and Geoff McBriarty (Cooke), Danny Boyce (Memorial University of Newfoundland), and Scott Flood (Blue Water Fisheries) Abstract: Lumpfish, a species native to the Gulf of Maine, are proven successful cleanerfish that can delouse salmonids […]

The effect of distal-end trimming on Saccharina latissima morphology, composition, and productivity

Lead PI: Gretchen S. Grebe Authors: Gretchen S. Grebe, Carrie J. Byron, Damian C. Brady, Adam T. St. Gelais, Barry A. Costa-Pierce Date: 2021 Abstract: As kelp cultivation increases around the world, so does the need for farm management strategies that produce specific crop characteristics, optimize yield, widen harvesting windows, and prevent biomass loss. Distal-end trimming […]

Resilience of cold water aquaculture: a review of likely scenarios as climate changes in the Gulf of Maine

Lead PI: Ian R. Bricknell Authors: Ian R. Bricknell, Sean D. Birkel, Susan H. Brawley, Tyler Van Kirk, Heather J. Hamlin, Kyle Capistrant-Fossa, Kimberly Huguenard, G. Peter Van Walsum, Zhilong L. Liu, Longhuan H. Zhu, Gretchen Grebe, Emma Taccardi, Molly Miller, Brian M. Preziosi, Kevin Duffy, Carrie J. Byron, Charlotte T.C. Quigley, Timothy J. Bowden, […]

Identifying Seed Source Populations Supporting the Culture of Atlantic Sea Scallops in Coastal Maine

Lead PI: Paul Rawson Co-PI: Huijie Xue Project Team: Phoebe Jekielek, Sarah Kingston, Caitlin Cleaver Abstract: The objectives of our proposed research are 1) to model (in-silico) the patterns of dispersal (propagation of larvae) along eastern coast to central Maine to predict source populations of scallop seed, 2) to increase the number of potential seed source […]

Scallop Aquaculture Initiative

Lead PI: Desmond Fitzgerald Project Team: Hugh Cowperthwaite, Blaine Grimes, Jake Ward, Jonathan Labaree, Gayle Zydlewski, Mike Bonney Abstract: The Gulf of Maine Research Institute, University of Maine, Coastal Enterprises, Inc., and the Maine Aquaculture Innovation Center plan to partner with Maine private farmers and coastal communities to look at the status of scallop aquaculture in […]

Understanding reproductive cycles and larval dynamics in cultured and wild populations of Placopecten magellanicus in Maine

Lead PI: Phoebe Jekielek Co-PI: Madison Maier Project Team: Marsden Brewer, Hannah Twombly, Connor O’Neill, Bobby Brewer Abstract: As successful shellfish culture is comprised of seed collection, grow out, and harvest, reliance on a variable wild set without hatchery supply is a potential bottleneck for consistent culture production in the emerging scallop aquaculture industry in […]

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

Lead PI: Phoebe Jekielek Co-PI: Amber Lisi Project Team: Hurricane Island, ME Department of Marine Resources Abstract: This project will further several priorities of the Department of Marine Resources’s scallop program and inform parallel work by Hurricane Island assessing local wild scallop populations and rotational closed areas. It will also provide comparative wild scallop growth […]

Optimizing production and products for scallop aquaculture

Lead PI: Damian Brady Co-PIs: Dana Morse Project Team: Struan Coleman, Hugh Cowperthwaite, Linda Auker, Christian Brayden Abstract: The giant sea scallop, Placopecten magellanicus, supports one of the most valuable and important wild fisheries in the United States, valued at over $430 million dollars ex-vessel value in 2015. Additionally, the U.S. imports 40 million pounds […]

Temperature Tolerance in Alaria

Project Description Sea surface warming is a key consideration when selecting candidate sea vegetable crop species in Maine. Researchers are investigating the temperature tolerance of edible kelp along the Maine shore to determine the effects of thermal acclimation on seedstock and crop yield. Project personnel collected zoospores and grew up individual genotypes of eight males […]
