Didymo's Impact on New Zealand Tourism

As the news spreads on invasive algae in New Zealand rivers, locals worry that foreign anglers might lose their enthusiasm. “For Mike Molineux, the didymo invasion means spending one and a half hours cleaning his boat, then leaving it to dry for 48 hours before taking it to another river to help tourists fish for brown and rainbow trout. ‘It’s getting pretty difficult to find somewhere to take them’ to fish, he said. `’This is a big concern for me.'” Jonathan Underhill on Bloomberg.com.
