Biocompatibility of intraperitoneally implanted TEMPO-oxidized cellulose nanofiber hydrogels for antigen delivery in Atlantic salmon (Salmo salar L.) vaccines

Lead PI: Sarah Turner PI Email: sarah.turner@maine.edu Project Team: Deborah Bouchard, Kora Kukk, Inga Sidor, Michael Mason Abstract: Disease outbreaks are a major impediment to aquaculture production, and vaccines are integral for disease management. Vaccines can be expensive, vary in effectiveness, and come with adjuvant-induced adverse effects, causing fish welfare issues and negative economic impacts. […]

Effects of Fishmeal Substitution with Mealworm Meals (Tenebrio molitor and Alphitobius diaperinus) on the Growth, Physiobiochemical Response, Digesta Microbiome, and Immune Genes Expression of Atlantic Salmon (Salmo salar)

A 12-week growth trial was conducted to assess the effects of mealworm meals, as a substitution for fishmeal, on the growth, physiobiochemical responses, digesta microbiome, and immune-related genes expression of Atlantic salmon (Salmo salar). Twenty Atlantic salmon parr (38.5 ± 0.1 g, initial weight) were stocked into each of 16 tanks in a recirculating aquaculture system. A fishmeal-based […]

A Farmer to Farmer Exchange Program to Support Innovation in Maine’s Aquaculture Sector

Lead PI: Chris Davis PI Email: christopher.v.davis@gmail.com Co-PI: Anne Langston Noll, Maine Aquaculture Innovation Center Project Team: Chris Davis & Anne Langston Noll, Maine Aquaculture Innovation Center Abstract: Small aquaculture businesses tend to operate using locally-derived processes and technologies, often without regard to practices conducted elsewhere, resulting in frequent “reinvention of the wheel”. An aquaculture-specific […]

Touch Tank for Sea Farmers: Healthy Coastal Communities Through Sea Food, Sea Farms, and Education

Lead PI: Sara Randall PI Email: srandall@downeastinstitute.org Abstract: The Downeast Institute has proposed this project to enable the purchase of a state-of-the-art portable marine touch tank and associated supplies. This touch tank will be taken to outreach events across the state by DEI staff and available to rent by aquaculturists for the same purpose. The […]

Domestication and Breeding of Northern Lumpfish to Accelerate Commercialization and Use for Sea Lice Biocontrol in the Northeast US

Development of oral vaccine delivery methods for prevention of disease in finfish culture.

Lead PI: Matt Hawkyard PI Email: matt.hawkyard@maine.edu Co-PI: Ken Cain (UI/NOAA), Joseph Dietrich (NOAA) Project Team: UMaine/ARI, University of Idaho, Oregon State University, NOAA Abstract: The development of marine and freshwater finfish aquaculture in the western United States is dependent upon on a stable and robust supply of juveniles. However, disease-associated mortality has been found to largely […]

Developing new techniques to detect off-flavor in water and Atlantic salmon tissues

Lead PI: Robert Harrington PI Email: robert.harrington@maine.edu Co-PI: Deborah Bouchard Project Team: Robert Harrington and collaborators from the USDA ARS NCWMAC Abstract: This project aims at developing a cost-effective and quicker method to detect off-flavor in Atlantic salmon grown in recirculating aquaculture systems (RAS). ARS and UMaine will examine methodologies to optimize off-flavor detection in […]

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 […]

Fish, farms, and shared futures: Defining public perceptions of land-based aquaculture to support sustainable decision-making

Lead PI: Laura Rickard Co-PI: Dr. Bridie McGreavy, Dr. Branden Johnson Abstract:The main objectives of this project were: Objective 1: Understand how support for, and/or opposition to, the present and/or planned siting of land-based recirculating aquaculture system (RAS) facilities is represented in public discourse in various spatially distributed U.S. communities. Methods included conducting in-depth interviews […]

A decision support system for sea lice management in salmon aquaculture

Lead PI: Kelly Cole PI Email: kelly.cole@maine.edu Co-PI: Ian Bricknell, Mike Pietrak & Damian Brady Project Team:Ellie Ghlan Abstract: Over 90% of Maine aquaculture landed value comes from farmed Atlantic Salmon. One of the more limiting and potentially environmentally destructive factors associated with salmon aquaculture in Maine is salmon, or sea lice (Lepeophtheirus salmonis (Krøyer […]
