The Iowa Walleye Challenge — a statewide catch-and-release fishing tournament — starts this Sunday, May 1. There are weekly prizes over the next two months, but the ultimate catch will be the data entered in a smart phone app.
Sean Simmons is president of MyCatch, the app for recording the location where the walleye are caught and a photo of the fish before it’s released back into the water.
“This is an experiment,” Simmons told Radio Iowa. “We’re going to see how well we can collect data across the state and see if this will be a useful tool to help the Iowa DNR to get a better state of the walleye fishery.”
One key part of the tournament is taking a photo to show the size of walleye being caught in Iowa. Participants may use a tape measurer or what’s called a bump board.
“It’s like a yard stick with a bump at the zero,” Simmons said. “So you put the nose of the fish against the bump and you take a picture of the fish on the bump board.”
A team will review the photos and determine if the fish meets the guidelines of the contest. There will be a live leaderboard on the app, showing who has caught the largest walleye. Simmons stresses that the goal isn’t to pull a lot of walleye out of circulation, however.
“We’re not against harvesting, but because we’re running this across the state and encouraging people to report as many fish as they can catch, we don’t want to unnecessarily deplete the resource,” Simmons said. “so the idea is to promote the release of the fish shortly after you catch them.”
Staff in state-run fisheries stock walleye in lakes across the state and conduct surveys in a handful of lakes and rivers to try to estimate the walleye population. Simmons is providing his app to the State of Iowa to not only collect data on the size of walleye that are caught over the next two months — but anglers are being asked to type in where they caught their fish. Simmons said secret fishing spots will stay secret.
“We will identify which waterbody it’s in, like the Des Moines River or the Rathbun Reservoir,” he said, “but the exact location is never revealed publicly.”
The important part of the tournament is collecting as much information as possible, Simmons said, so prizes aren’t necessarily going to go to the person who catches the largest fish — and there will be prizes for people who don’t catch any fish.
The MyCatch app has been used for several competitive fishing tournaments in Canada and a few locations in the United States. “We ran the Ontario Ice Fishing Challenge where towns across Ontario competed to see who would be the ice fishing capital of Ontario,” Simmons said.
The MyCatch app handled over 700 participants who caught-and-released 12,000 striped bass in the Miramachi Cup in New Brunswick last October.
