The Wyoming Game and Fish Department is studying invasive fish called burbot, to figure out what parts of the Green River they occupy at different times of year.
The department’s Darren Rhea says that could help them come up with ways to reduce the burbot population. He says burbot are problematic for the river’s ecosystem.
“They are almost exclusively a pisciverous fish, so they prey almost exclusively on other fish,” Rhea said.
Rhea says that’s taking a toll on native fish populations. His team has put tracking devices into some burbot, and they’ll monitor the fish’s movements for about a year.
