United States

Louisiana—Biofloc Session at WAS, New Orleans


Andrew J. Ray, Ph.D., Assistant Professor at Kentucky State University’s Aquaculture Research Center, reports on the Biofloc Session at the upcoming WAS Meeting in New Orleans, Louisiana.


We are set to have another exciting Biofloc Session at the Aquaculture America Conference in New Orleans on Sunday, February 22, 2015.  We’ll have a full day of presentations on microbiology, Vibrios, probiotics, management, water quality, toxicity, polyculture, catfish, feeds, feeding strategies and trophic dynamics.  


One of the themes of the Biofloc Session will be Indoor Systems.  While not every presentation will touch on this issue, I would like to encourage the speakers and the audience to think about the implications of operating biofloc systems indoors.  One of the emerging trends seems to be operating biofloc systems inside buildings, and I would like to facilitate some discussion about the challenges and opportunities associated with this approach.


Please see the current schedule below.  The schedule was changed on February 7, 2015, and there will be an addendum in the conference program reflecting this change, so make sure to follow this and catch all the great presentations.


There will also be a presentation on biofloc economics in the Shrimp Aquaculture session at 4:00 p.m. on Friday, February 20, 2015.
