As live-imaging sonar surges in popularity, researchers at the University of Minnesota are preparing to study if the technology could threaten future fish populations across the state.
Often known as forward-facing sonar, the technology lets anglers find and track fish in real time. It’s a major shift from traditional sonar, which only shows what’s beneath a boat.
The technology’s rapid rise has divided anglers. Supporters say it makes fishing more engaging and could attract younger participants to the sport. Critics argue it gives anglers too much of an advantage and could increase pressure on vulnerable fish populations.
“There’s a lot of mixed feelings and strong feelings about this technology usage, but we don’t really have a foundational baseline test or understanding about how this technology works in Minnesota lakes,” said Cam Mosley, a fisheries ecologist and postdoctoral research fellow at the university…
