The North Carolina Aquaculture Development Conference is proud to announce and sponsor the following
workshop:
RECIRCULATING AQUACULTURE TECHNOLOGY WORKSHOP
Lake Wheeler Road Field Laboratories
North Carolina State University
Raleigh, North Carolina
December 5 & 6, 2008
About this Workshop:
Aquaculture, as a business, seems to be able to capture the imagination of a wide variety of individuals
worldwide. Recirculating aquaculture technology (systems that recondition and re-use water) is the latest
sector in aquaculture to have attracted attention and considerable venture capital. This workshop is
designed for a broad audience. We will seek to provide non-biased, research-based information to those
that are interested in, or those using recirculating aquaculture fish production systems. The information
presented comes either from the first-hand research results and experiences of the presenters or those of
collaborators or colleagues around the world. Species currently being cultured at the North Carolina State
University Fish Barn are tilapia, yellow perch, southern flounder, and black sea bass. Species being
cultured in cooperating marine recirculating systems research include summer flounder and black sea bass.
Workshop registration includes a technical workbook and CD, and coffee, tea and lunch for both days.
About the Presenters:
Dr. Tom Losordo is a Professor in the Department of Biological & Agricultural Engineering at North
Carolina State University. Dr. Losordo has earned a Bachelor degree in Biology and a Masters degree and
Ph.D. in Agricultural Engineering. Involved in aquaculture for more than 31 years, Dr. Losordo currently
heads a program of applied research and extension (public service) in the area of recirculating aquaculture
production systems. Known as the North Carolina Fish Barn program and in its 19th year of development,
this program develops, evaluates and demonstrates new technology for intensive fish farming at the
commercial scale. The program is currently centered around a commercial scale recirculating production
system located on the campus of NC State University. While focusing on tilapia and yellow perch, the Fish
Barn program has also investigated the production of rainbow trout, hybrid striped bass, flounder,
ornamental goldfish, koi carp, and black sea bass in recirculating aquaculture systems.
Mr. Dennis DeLong is an Extension Aquaculture Specialist in the Department of Biological & Agricultural
Engineering. Mr. DeLong has earned a Bachelor degree in Biology and a Master of Science degree in
Management. Mr. DeLong has been involved in both commercial aquaculture activities and research and
development for more than 30 years. Mr. DeLong manages the research and demonstration activities
within the NC State Fish Barn program. Additionally, he provides extension assistance in aquaculture to
citizens and agri-businesses in North Carolina.
