What happens to aquaculture pathogens during the disinfection process?

To answer this question and test the efficacy of a novel ultrasound disinfection device being developed by the HatcheryMatch project, researchers at project partner University of Malta have taken a closer look at harmful bacteria using powerful scanning electron microscopes. SEM imagery uses a beam of electrons to show scientists the surfaces of even the smallest objects, including bacteria, in high resolution detail.

HatcheryMatch researchers ultimately found that the aquaculture pathogens are severely affected by the ultrasound disinfection process. Although these initial results are promising, Malta-based researchers will collaborate with researchers in China to test the application of this new technology in an integrated marine recirculating hatchery system stocked with turbot larvae. We can’t wait to see the impacts ultrasound disinfection has on larval fish health and welfare in RAS!
