2014 ARI Seminar

You can find the recording of Nick Brown’s 10 April 2014 seminar, “Incorporating the polychaete worm, Nereis virens into marine aquaculture systems” at the seminars website. Future ARI seminars will be available at the same link. Note: the videos may take a minute to load.

Experimental Scallop Farming Project

Wednesday, November 20th, 2013

Chris Vonderweit (Dept of Marine Resources) and Dana Morse (Maine Sea Grant)  visited Kevin Scott at the Salt Pond site, and Marsden in Stonington. With them were Bill Trotter and Gabor Degre of the Bangor Daily News; they took a bunch of photos/video and Bill put together a great articlae viewable at

The experimental scallop farming project continues to go well at both sites, and we’ll start to see effects of density experiments soon: there is a lot of growth sideways (Shell Width) and the shells are standing taller too (Shell Depth).  We have started to collect a little data on the Shell Height/Shell Width ratio to capture this, but there’s not much to report on there yet.

At one site the Aquatrays got hit with a pretty heavy barnacle set, including the scallops inside the cages, though the shellfish bags seemed to avoid this more or less…unclear as to why that was.  Mortality at both sites was near zero. And biotoxin sampling continues but again nothing to report yet.   For more information contact Dana Morse (

Marine aquaculture in the coastal zone has the potential to help solve several societal problems including contributions to the global food and energy systems. These systems are subject to complex and dynamic interactions among natural and human-driven processes.

A major challenge is to understand the dynamics of this coupled human-natural system in order to inform societal decisions about the intensification of marine aquaculture in the coastal zone. Such understanding requires integration of a broad range of disciplines from the natural, social, economic and behavioral sciences.

Faculty interested in joining us in the development of this proposal are invited to contact

A note to all fellow seaweed enthusiasts: our colleagues at Maine Sea Grant have created a new page called Maine Seaweed Social. It is a place to connect and share ideas, photos and experiences. The link is below; please spread the word so that we can move this industry forward!

ARI Graduate Student Explores Link Between Carbon Dioxide and Blindness in Cod

Tuesday, August 7th, 2012

ARI Graduate Student Kevin Neves has recently completed his research project looking into the question of ….What caused hundreds of Atlantic cod in a UMaine research project at CCAR in 2004 to develop severe cataracts at higher rates than expected?  He found that cod living at high densities were exposed to higher levels of carbon dioxide, causing them to grow cataracts and eventually go blind. Fish that cannot see to locate their food cannot grow.  Kevin expects to defend in Fall 2012.  More information on the project can be found at the following link.

Colleagues in Dept of Chemistry Receive Award to Develop Nitrate Monitor

Wednesday, August 1st, 2012

Jim Killarney and John Ahern have been working with the Aquaculture Research Institute on development of a gadget to monitor nitrates in recirculation systems and bioremediation sites.  They have recently been awarded an MTI seed grant on their project Chemiluminescence Detection of Nitrates and THMs. The ability to detect nitrates and disinfectant byproducts in place and in real-time greatly improves process controls and pollution monitoring for aquaculture and drinking water treatment.  The University of Maine is developing a sensor that takes advantage of a novel spectrometer design that measures the chemiluminescence of these compounds.  The scope of this project is to obtain the technical and customer requirements of a chemiluminescence based sensor which will allow us to design our beta prototype device.  The lightweight, durable monitoring device will be deployable and provide pollutant concentration data in real-time to end users.

MTI Award for Vaccine Development

Wednesday, August 1st, 2012

Drs Tim Bowden and Ian Bricknell of the Aquaculture Research Institute, UMaine have been awarded a new MTI seed grant for novel vaccine development.

Vaccines are a key method of controlling disease in finfish aquaculture. However, most fish vaccines consist of crude bacterial suspensions where the mechanisms of protection are not well understood. Recent research by the applicants has identified a novel group of proteins that are expressed by bacteria during the end stages of an infection. Vaccines that include these proteins were very protective against the fish pathogen Aeromonas salmonicida in small-scale laboratory trials.
