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 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.
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.
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.

Come and find out more about our aquaculture research facilities at:
The Darling Marine Center, Walpole and The Center for Cooperative Aquaculture Research, Franklin.
In the early 1970′s Dr. Herb Hidu was hired by the University of Maine to establish a shellfish aquaculture facility at that Darling Marine Center. For 30 years he taught and trained students in the art and science of growing the Eastern oyster in the cold waters of our coast. Many of his early students were the first entrepreneurs of Maine’s thriving oyster industry. The Darling Center shellfish research has expanded beyond Maine’s oysters to a wider variety of species including mussels, scallops, whelks, European oysters, razor clams and quahogs. Both Basic and applied research is supported at the center with the goal of improving knowledge of shellfish and sustainable methods for the fishing and culture of shellfish. There are a number of state-of-the-art facilities at the Darling Marine Center to support the University of Maine’s aquaculture research. Including:
Hatchery based research at DMC is often conducted in collaboration with industry partners, the shellfish working group, and the Maine Aquaculture Innovation Center. These collaborations provide the University of Maine researchers access to some of the most pristine and productive culture sites in the Northeastern United States.
The facility (CCAR) is located on Taunton Bay in Franklin, Maine. After taking over the property in 1999 we set about modernizing and expanding the facilities, upgrading the systems to include innovative recirculating technologies, waste water treatment systems and to comply with all relevant building and safety codes. In 2003 we built the “MTI Cluster Enhancement” funded buildings to add multipurpose space for business incubation and R&D. In 2005 we added the EDA funded marine fish hatchery, to enable us to produce a variety of marine fish for the industry. In addition to having the facilities, experience and knowledge, we are able to assist industry partners in applying for outside funding for their R&D projects and will help design and manage R&D projects from basic research, all the way through to the design of full scale commercial farming. The flexibility of the facilities allows for a wide range of work on a wide range of species. These include: cold water marine fish, including Atlantic halibut and Atlantic cod; tropical marine fish, such as Clown fish; a variety of invertebrates including polychaete worms and sea urchins; and marine algae.

Aquaponics is the symbiotic cultivation of plants and aquatic animals in a recirculating environment. Water is cycled between fish tanks and plant growing areas, and the fish waste acts as a fertilizer for the plant crops. These systems are efficient and water-wise, using 90% less water than conventional vegetable gardens or aquaculture systems.
Aquaponics is an amazing tool for teachers and educators. Aquaponics systems bring science and ecology to life by showing a living, breathing example of what can happen when people work with nature to help grow their food. Lessons can range from biology, physics, and chemistry, to horticulture, zoology, and nutrition.
Come along to this workshop and learn how to put together a classroom sized aquaponics system. With opportunities for hands on experience, and ideas for lesson plans, this no-fee course offers the opportunity to find out more about a dynamic, interactive teaching tool!
Please register for this event. Limited spaces available.
Registration is now open for a May term/summer course at the Darling Marine Center on Techniques in Shellfish Aquaculture. Registration opened on February 24th. To find out more about this course please go to this web page.
This course is open to both UMaine and non-UMaine students. UMaine students can register directly through MaineStreet. Non-UMaine students, please register through the Office of Continuing and Distance Education/ Summer University by calling 207-581-3143.
Well that was a busy few days at Aquaculture America in Las Vegas! Our first impressions of the meeting were that it was a little smaller than last years’ in New Orleans. However, it was certainly as glitzy – being held in the Hotel Paris and Casino on Las Vegas Boulevard. We all ended up with rooms on the 27th floor of the hotel with almost amazing views of the strip (which must use as much electricity in a month as the whole of Maine does in a year!).
So how was the meeting? For us it was fantastic – we had many great meetings with the aquaculture industry and support companies. Certainly the two big themes we saw emerging from the meeting were fish health (in particular sea lice control) and seaweeds (especially seaweed culture for aquaculture feeds and nutriceuticals).
We had some amazing conversations with the US poultry feed industry concerning our IMTA research and possible outlets for both seaweed products and bivalve meal in non-aquaculture related feeds stuffs.
One of the most amazing stands on display was the Alltech stand displaying a concept farm of the future, where finfish and algae culture is combined with traditional terrestrial agriculture to create a carbon neutral farm. Well worth going to http://www.alltech.com/future-of-farming and checking out the computer model there for more details.
The conference component of the meeting had some very important sessions; not least was the aquaculture education lectures where we learnt about the new Aquaculturehub social media site (www.aquaculturehub.org) and the amazing education project A.T.OL.L. where all levels of aquaculturists can access free training videos (http://www.aquaculturehub.org/events/aquaculture-training-on-line-learning-atoll). Look out for some videos from us on fish ectoparasites, egg quality and vaccines later this year.
The session on the Coexist project US is another exciting opportunity for collaboration between stakeholders in the Marine Coastal Zone to open a dialog about the use of coastal waters. It is in its early days in the USA – not so much a project as a “groundswell” right now – but we would recommend that everyone contribute to this project as it looks as if it will be very important in helping develop sustainable policies for all of us.

ISAv is still an issue in aquaculture and we were treated to some excellent talks on this serious disease by Dr. Brian Glebe from DFO Canada and some of the exciting work he has been doing on vaccines. Brian is planning to retire from DFO later this year but he did tell me that he’ll still be active in the field, which is great to hear because his group has produced seminal work over the years.
The final session we attended was the recirculating aquaculture session where Atlantic Pacific Farms of Maine presented their abalone system and our very own Robert Bishop (UMaine 2014) gave a great presentation.
Socially the formal end of each day was marked with the traditional beer in the exhibit hall where we met up with old and some new friends. Now all we have to do is wait for our flight home and give my liver time to recover until we do this all again next year!
Mike Pietrak, Dr Sally Molloy, Deborah Bouchard and Dr Ian Bricknell of the University of Maine Aquaculture Research Institute have been awarded $14,387 by MTI for the development of a new biological trap for sea lice.
The sea louse is currently the greatest economic threat to Atlantic salmon culture in the North Atlantic. A biological sea lice trap consisting of mussel rafts containing slow-release semiochemicals may reduce sea lice densities while contributing to environmental and economic sustainability. Semiochemicals would attract planktonic sea lice larva without affecting other plankton. The filter-feeding mussels would remove sea lice from the water column. We propose to demonstrate that the addition of semiochemicals to a mussel mass enhances the reduction of sea lice settlement on co-habitating Atlantic salmon as proof of concept to develop and commercialize a biological sea lice trap.
