Spring Recirculating Aquaculture Systems (RAS) Technology Workshop - May 9-11, 2017


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 nonbiased, research-based information to those that are interested in, or those using recirculating aquaculture fish production systems. The information presented in this workshop comes either from the firsthand research results and experiences of the presenters or those of collaborators or colleagues around the world. Workshop registration includes a technical workbook, memory stick with applicable resource materials, break refreshments, and lunch each day.
