Judas Fish Could Help Curb Asian Carp in Minnesota, But First We’d Have to Figure Out How to Sterilize Them
Invasive species are, well, invasive. The label's given to those critters that didn't originate from a given area but have moved in and are destroying the habitat for other species. Generally speaking, they upset the somewhat delicate cycle that's already in place. Asian carp is one example of an invasive species in Minnesota, though they don't appear to be widespread yet. Peter Sorensen, director of the Minnesota Aquatic Invasive Species Research Center, thinks that "Judas" fish could be used to track down any populations and remove them. First, we'd have to figure out how to sterilize them, though.
