Lake Michigan anglers boost local Illinois and Indiana economies

August 22nd, 2018 by

The economic impact of the Illinois and Indiana Lake Michigan recreational fishery on the local economy was more than $44 million in 2015, according to Illinois-Indiana Sea Grant (IISG) research. Recreational fishing supported 407 jobs in the two states.

IISG funded two studies to estimate the economic value of the Lake Michigan fishery in Illinois and Indiana. At the Illinois Natural History Survey (INHS), Sergiusz Czesny, Craig A. Miller, and graduate student Elizabeth Golebie looked at how much anglers actually spend and estimated the impact of those dollars.

They questioned anglers about their typical fishing trip expenses and found that shore-based anglers spent an average of $56 and boating anglers spent $255. Annual creel surveys, which are done in person along the shoreline, provided a point of contact so that the researchers could target their questionnaires to anglers who fish in Lake Michigan. In Illinois, INHS is responsible for the creel surveys along the shoreline in Cook and Lake counties. In the Indiana counties of Lake, Porter and LaPorte, the creel surveys are done by the state’s Department of Natural Resources.

The researchers estimated the total economic impact of Lake Michigan non-charter anglers in Illinois waters at $22.4 million, providing 231 jobs. Indiana non-charter anglers contributed $12.7 million to the local economy, supporting 176 jobs in the three counties. Illinois charter fishing anglers were also included in this study and comprised the remaining economic impact that altogether totaled more than $44 million.

“There’s a wide range of economic activity going on with fishing,” said Miller. “These numbers provides more evidence that we need to maintain these fisheries. Several sectors of the economy are dependent on a healthy fishery with healthy fish populations and angler access.”

In both states, the overwhelming majority of fishing—75 percent—was for salmon species, which include coho and chinook salmon, as well as brown, lake and rainbow trout. Only 6 percent was dedicated to yellow perch, and the remainder for other species, such as bass.

Mitchell Zischke and graduate student Xiaovang He at Purdue University, and Benjamin Gramig at the University of Illinois tell more of the story in their economic evaluation research. Using a non-market approach to quantifying the value of the Lake Michigan fishery in the two states to the anglers themselves, they estimated anglers’ willingness to pay for a day-trip spent fishing. They added questions to the 2015 Illinois and Indiana creel surveys to do a travel cost study, estimating the value of fishing based on how far anglers traveled and how much time it took to get to fishing sites.

“In addition to direct expenditures, anglers allocate time and effort to fishing instead of work or other activities, and this is the basis for these estimated values,” said Gramig.

Anglers interviewed during the 2015 creel surveys along Lake Michigan were willing to pay an average of $30 to take a day trip fishing and their average travel distance was 28 miles. Illinois anglers have a slightly higher willingness to pay than those from Indiana and boaters have a higher average, at $40, than shore-based anglers, who are willing to pay $26.

The total estimated non-market economic value of recreational fishing was $3.6–4.0 million, which represents additional value over and above expenditures on food, fishing supplies and other associated items included in Miller and Czesny’s estimates.

“Support for the economy through recreational fisheries is a complex web,” said Zischke. “Having some understanding of these numbers is important. For example, if there’s a potential to open up a fishing site, it’s critical to know that it may add millions of dollars to the economy.”

Zischke and Gramig also looked at 30 years of creel survey data to get a historical perspective on the Lake Michigan fishery and connect trends with environmental or management changes.

The data revealed that while the two states share Lake Michigan waters, they have noteworthy differences in fishing practices. “We noticed a large decline in the fishing effort in Illinois,” said Zischke. Fishing effort back in the mid-1980s added up to over 2 million angler hours per year—since the early 2000s it has stabilized at 500,000 annual angler hours.

Zischke attributes the reduction in Illinois fishing hours to the drop in yellow perch numbers. “The decline in fishing effort follows a similar timeline to declines in catch rates of yellow perch,” he said.

“In Indiana, however, we did not find a similar decline in fishing hours,” said Zischke. “Fishing hours have been stable at 300,000–400,000 over the last 30 years. Typically, the catch rates of yellow perch in Indiana have been historically lower than in Illinois and they have actually been quite stable through time.”

The historical creel survey data also revealed that most Illinois anglers have engaged in shore-based fishing, whereas Indiana anglers have been predominantly on boats. This may be due to the fact that Illinois has a higher population along the lakefront and more access to fishing along its shores.

The research team has made the creel surveys’ 50,000 records collected from 1986 to 2013 available for other researchers, resource managers and anglers to easily access on the Angler Archive website. Plans are in the works to update the website with more recent data.

Anglers and researchers can reel in Lake Michigan fishing data

July 19th, 2017 by

A goldmine of recreational fishing data is now available in one place thanks to researchers and state government officials in Illinois and Indiana.

The website, Angler Archive,, is the brainchild of Mitchell Zischke, IISG research and extension fishery specialist at who saw the need for having the information more easily accessible when he was doing his own research.

The site currently contains over 50,000 records gathered between 1986 to 2013 by the Illinois Natural History Survey (INHS) and the Indiana Department of Natural Resources (Indiana DNR) in southern Lake Michigan during their seasonal “creel surveys.” Indiana not only surveys the lake but also nearby streams. Zischke will be updating the website as more data becomes available.

Creel surveys are conducted by state officials who interview the anglers while they’re fishing or at the end of their trip. The questions focus on how many fish and what species they caught; how much time they spent fishing; and where they caught the fish.

The website mirrors the creel surveys, but allows users to customize how and what data they want to see. They can use the drop-down menus to display and compare data by angler type, month, and species as well as generate and export the informaiton as a graph.

“In fact, I’m working on a project right now, analyzing data from the 80s and the 90s,” Zischke said. ”I’m finding there seems to be a relationship between the decline in yellow perch and the decline in the number of people fishing and the amount of time they spent fishing. Really, it’s just the beginning of diving into all this data.”

Researchers in both states who head up the creel surveys are looking forward to being able to share the data easily.

“I think it’s great. The more of our info that we collect that the public can see, the better,” said Ben Dickinson, Indiana DNR assistant Lake Michigan fisheries biologist.

“We try to go around to different fishing clubs and stakeholders and present this info, and so it’s nice to have a tool to point people to.”

Anglers frequently ask Charles Roswell, aquatic ecology assistant research scientist at INHS, who assisted in providing the data from the Illinois side, how the data from the surveys are going to be used.

“We have a short write-up on our website, describing how fisheries managers use the data, but I always thought it would be nice to have somewhere to direct people to look at what came out of the surveys, what data were actually collected, and what the data showed,” Roswell said. “This is something I always thought would be useful.”

This information spanning over 31 years will no doubt be useful and more easily accessible to researchers, fisheries managers, and curious anglers. For Zischke the data is already yielding some insights.

“It’s good to be able to look at these data now in a time series, as opposed to having to read a report every year. It highlights some interesting trends in fishing effort and in catch of some species, Zischke said.

“Now we’re in the process of exploring what may have caused some of these trends these through time.”
