Smith-Root scientists recently attended the Salmon & Trout Spawning and Biosecurity Workshop (Pendleton, OR) as well as the Northwest Fish Culture Conference (Portland, OR) to present exciting results from their recent publication in the Journal of Aquatic Animal Health. The study—led by Smith-Root researchers, Phong Nguyen (M.S.) and Austen Thomas (Ph.D) and conducted at the University of Idaho’s Aquaculture Research Institute—focused on the rapid detection and monitoring of bacteria directly from fish-rearing water. Their findings showed that the Biomeme field molecular analysis tool performed comparably to traditional laboratory-based analysis for the detection of Flavobacterium psychrophilum—a potentially pathogenic bacteria that is common in salmonid aquaculture. Although the two methods detected similar trends in the fluctuation of bacteria in the water without significant differences, the study highlights that the Biomeme platform allowed the researchers to extract and analyze their samples in <1 hour as opposed to the laboratory protocol which required 3 days to complete. Lead author, Mr. Nguyen, emphasized the significance of this research by saying, “Rapid field detection of microbes directly from water samples will revolutionize the field of aquaculture and aquatic sciences. The faster you get results, the more informed you are and the better your decision-making process.” Dr. Thomas, who leads environmental DNA research at Smith-Root, believes that eDNA science combined with cutting-edge field technologies will open new doors to better understanding the interaction between the microbial community and fish.
