Written by Ryan Newton, an assistant professor at the University of Wisconsin-Milwaukee School of Freshwater Sciences (SFS), this 20-page paper describes the importance of microorganisms in freshwater aquaponics. It’s the first in a series of aquaculture technical briefs produced by Fred Binkowski, senior scientist at SFS and aquaculture outreach specialist at Wisconsin Sea Grant.

Titled “Microorganisms in Intensive Aquaponics,” the paper starts with an explanation of exactly what microorganisms are and then covers the diversity of roles they play in aquaponics systems. Although they may not be the first part of an aquaponics system that comes to mind, microbes are crucial to the healthy functioning of the system. The paper includes suggestions for biosecurity and suggestions about pre- and probiotics. A table of common freshwater fish pathogens is also included.

Binkowski said, “This is a great resource for fish farmers because it provides a clear picture and understanding of the function of the invisible workers — the bacteria – that form one of the most important components of a healthy and productive aquaponics system.”
