LANSING — The fall of salmon in the Great Lakes can be seen as a good thing ecologically although some people prefer native species, says biologist and author Carson Prichard.

But the personal perspective and the local impact often are forgotten.

“I think it’s just been overlooked — they had tried to look at the economic impacts of the loss, but not on the local scale whatsoever,” said Prichard, the author of The Salmon Capital of Michigan: The Rise and Fall of a Great Lakes Fishery (Wayne State University Press, $26.99).

The book, set to be published in April, is about the residents of Rogers City, a once-booming Lake Huron fishing community, who share personal stories of how the introduction and depletion of salmon impacted them.

Prichard has spent a lifetime learning about the outdoors as a Michigan native. He got his bachelor’s degree in biology from Grand Valley State University and a master’s degree in fisheries and wildlife at Michigan State University. He then earned a doctorate in earth and ecosystems science at Central Michigan University.

As a biologist in Muskegon for the National Oceanic and Atmospheric Administration, he was made aware of the discourse about non-native salmon in the lakes.

He never planned to write a book, but noted the lack of cultural focus on this ecological event and said he was drawn to telling that side of the story.

“I ended up getting my Ph.D., but by the time I was finishing that, I kind of didn’t want to do science as a career anymore,” Prichard said.

The COVID-19 pandemic gave him an opportunity to rethink his career options. Prichard said he decided to write the book because the story blended personal connection and science.

That was a solution to using his education but not continuing along a path in hard science.

Government agencies had published a lot of research that told the science of the changes brought by introduced salmon, he said. What is less reported is the impact the fish had on towns where the salmon fishing industry once flourished.

“That’s a lot of tourism and cultural and physical presence to just go away,” Prichard said.

Great Lakes salmon have had a long and complex history since state officials brought them to the lakes nearly 60 years ago.

They were a solution to another invasive fish, the alewife, Amber Peters, an associate professor with the Michigan State University Department of Fisheries and Wildlife and who has worked with Great Lakes salmon.

Alewives were a nuisance and harmed the fishing and tourism industries. Cities, like Chicago, encouraged tourists to have a fun day at the beach, but alewives often die in massive numbers and wash up dead and rotting, Peters said.

“They’d bring in trucks and bulldozers to take them away,” Peters said. “But really, the biological solution made a lot more sense.”

That solution was salmon. Although not native to the Great Lakes, the hope was that the fish brought from Oregon and Washington would feed on the growing alewife population.job

The salmon did their job and more, not only creating ecological balance and solving the alewife problem but also bringing economic prosperity and a new style of fishing similar to deep-sea ocean fishing, she said.

“In one fell swoop, we’d created this great sports fishery and we got rid of the stinky fish that were washing up all over the beach,” Peters said.

Prichard received a grant in 2021 from the Great Lakes Fishery Commission to focus on Rogers City. State officials once stocked this Lake Huron city with more salmon than anywhere else in the state.

“They had a fishing tournament there, a big one that brought people in to fish from Ontario, New York, Detroit, all over the Great Lakes states, basically,” Prichard said. “There were lots of boats, money and tourism coming into northern Michigan.”

But his book is part of a larger conversation, he said. Many people believe that the lakes would benefit from fewer salmon and more native species like lake trout and walleye. Those native species are outnumbered and compete with salmon for food.

His book is less about fish science and more about how salmon have benefitted life and culture in fishing communities, he said.

“I have been exposed to some negative sentiments along the way, biologists against non-native species, and it could easily be construed as a good thing that the salmon have collapsed,” Prichard said. “I think there was a lot lost culturally with the salmon collapse, and I want to give a voice to the people whose lives were positively affected by them.”

The cause of the collapse of the salmon population is difficult to pinpoint. There are many reasons, including inconsistent stocking efforts, Peters said.

“A couple of likely contributing factors are the salmon did their job too well and they ate the alewives down to a point where the population was not replenishing itself enough to feed, and maybe some of the changing temperatures of the lakes,” Peters said.

Even those who know nothing about the salmon in the Great Lakes could benefit from reading and understanding the many sides of the story, she said.

“It just shows you how complex the big picture really is. Books like this really help.”
