First-Generation College Student Makes Splash in Fish Health Research Improvements

MOSCOW, Idaho – For some, a college education is overrated, especially in hard economic times when a diploma from a four-year institution no longer guarantees a job.
While growing up, David Burbank’s family was of this opinion and did not encourage him to attend college just to have “the experience.” But Burbank had a different vision.
Burbank’s passions for fishing, the outdoors and science led him to the conclusion he needed a degree to do what he loves – apply principles of microbiology to improve fish health.
Burbank is the first member of his family to attend college. After a year in a transfer program at Boise State University, Burbank says he came to the University of Idaho College of Natural Resources because of its strong fisheries program, smaller classes and community “feel.”
Burbank, a University of Idaho graduate student studying fish health, currently is conducting hands-on research to improve the aquaculture industry’s understanding of probiotics. Probiotics are any bacteria or microbes that can be beneficial to the host, including disease treatment, as opposed to antibiotics, which fight against bacteria. Burbank recently received a McNair Graduate Assistantship to partially fund his research project to discover an effective probiotic treatment for Cold Water Disease (CWD).
CWD is the No. 1 disease facing the commercial sector of the Idaho trout industry. The disease is a worldwide problem for rainbow trout reared for commercial aquaculture and in resource enhancement fish hatcheries. In recent years, economic losses from this disease in the trout industry are estimated at approximately $9 million in Idaho alone – but are much higher worldwide.
“A new trend in aquaculture is learning which priobiotics effectively treat specific diseases,” said Burbank. “Using probiotics may have the potential to decrease reliance on antibiotics, which in the long run will save money that can be used to improve production facilities.”
Burbank worked with his mentor, Ken Cain, associate professor of fishery resources, to culture 318 strains of bacteria, which were screened to see if they had potential as probiotics.
“Of the 318, we discovered that 16 strains of bacteria did not cause direct mortality in the fish and could survive in the gastrointestinal tract and inhibit CWD in vitro,” said Burbank. “Now we are examining the 16 strains one by one to discover which will be an effective probiotic against CWD.”
“Dave’s work is extremely important to the Idaho trout industry, as well as to hatcheries raising trout and salmon to be stocked from sport fishing,” said Cain. “Recent lab and field trials have identified two probiotics that greatly reduce the effects of CWD, and the university hopes to partner with interested companies to eventually develop a commercial product.”
In addition to the research Burbank conducts as a graduate student, he also participates in the U.S. Fish and Wildlife Service’s Student Career Experience Program (SCEP), to gain additional experience in the aquaculture industry. SCEP offers curriculum related employment to students in certain academic disciplines.
During winter breaks and summers, he works at the Willard National Fish Hatchery in Cook, Wash., raising fish, monitoring water quality and visiting different facilities to experience feeding techniques and genetics practices.
After earning his master’s degree in fishery resources, Burbank will have a guaranteed fisheries biologist position at Willard.
