Univ. of Minnesota researchers look to harness fish virus in fight against invasive carp

University of Minnesota researchers see a recent fish virus outbreak as a chance to combat an invasive species plaguing state lakes.

Researchers at the University’s Minnesota Aquatic Invasive Species Research Center (MAISRC) in St. Paul have been studying the usage of Koi herpesvirus (KHV) — responsible for recent carp deaths in Minnesota lakes — for potential bio-control of invasive carp. Koi fish are a subspecies of common carp, making them both susceptible to the virus.

“We want to find ways to kill carp and zebra mussels and all these invasive species,” said MAISRC Director Nick Phelps. “We started this particular project in 2014 — went two years and didn’t see [the virus] anywhere, then saw it in seven to eight lakes in a matter of a month and a half.”  Click on the following sentence to access the full story.

“It can be a little alarming when thousands of fish wash up on the shore. People wonder if the water is safe.”
