"It's a lot colder and generally when you've got blue skies, it's high pressure and those fish that are generally active will not be so active," Team USA Ice Team Director Mike McNett said about Saturday's conditions.
Anglers said the weather made for a slow first day on the ice. Team USA competitors are still hopeful they'll be able to catch more fish on day two.
They are in 7th place after the first day of competition.
"We didn't think it would be quite this tough, let me tell ya," Team USA angler Myron Gilbert said.
Single digit temperatures and clear skies meant Team USA had a hard time catching high-quality fish.
"Predominantly we're on a crappie bite here and those conditions especially with the high skies like that is not good for crappie bite. So, it panned out about how I thought it would be. It was going to be a real, real slow bite," angler Mike Boedeker said.
He caught to decent sized fish Saturday and lead the way for Team USA, ranking 11th overall.
"We just got caught in a weather front that just shut the fish right off completely," he said.
But the sun was a welcome sight for dozens of spectators that crowded the Big Eau Pleine Reservoir.
"It's great to be able to visit with people all over the world," said one visitor.
Anglers for Team USA said despite a slow first day, their strategy won't change Sunday.
"If you're disappointed because fishing wasn't easy, you've come to the wrong place," Gilbert told Newsline 9.
"We're still going after the high crappies," Boedeker added.
Anglers said it only takes one bite to change everything and they're going to hit the ice Sunday with a goal.
"If we can get four fish in a zone, we could win out," Boedeker said.
The second day of competition starts at 9:00 a.m. Sunday.
