As an avid angler, Great Lakes Now Host Ward Detwiler has encountered suckers, a bottom-feeding family of fish that are present in all five Great Lakes and spawn in the rivers of the watershed.
But he’s never been terribly mindful of them.
“It’s never something you’re really out looking for,” Detwiler said.
Suckers, though, are important to the entire food web of the system, according to Karen Murchie, director of freshwater research at the Shedd Aquarium in Chicago.
“What they do is a lot of important stuff,” she said. “They also move nutrients around as they move from habitat to habitat.”
Suckers are also food themselves for osprey, loons, eagles and small mammals.

Some of Murchie’s research relies on citizen or community scientists who live near lakes Michigan and Superior and do periodic counts of sucker fish during 10-minute observation periods in the spring.
Great Lakes Now compiled a list of citizen science opportunities around the region. Check it out here:

“If someone is interested in participating in the study, we want to know if there’s a creek or river close to where they live or work that’s going to be convenient that has a known run of suckers,” Murchie said. “We want it to be something they can do easily and every day, basically starting not long after ice off and while snow is still melting, they’re out looking in the creeks and saying, ‘Hey, are the suckers there yet?’ and reporting the information.”

Great Lakes Now introduced viewers to Murchie in the episode “Best Supporting Fish” from Episode 1026 of the monthly program.
