A Great Lake revival
The demise of alewives and salmon in Lake Huron brought something nobody expected: An explosion of native species. Is Lake Michigan next? And could a more diverse ecosystem offer protection against Asian carp and other invaders?

Linwood, Mich. — Ernie Plant's eyes get wide when he talks about how spectacular Lake Huron's salmon fishing was back in the late 1980s, when his dad would take him up north on Friday nights after his high school football games.
They'd spend fall weekends along the shore of the lake chasing the chinook that were chasing the alewives that ran so thick they even teemed in water-filled ditches along coastal roadways.

"We never had a boat," said the sales manager at Frank's Great Outdoors, a gear and bait shop north of Bay City. "But we didn't need one."
When Lake Huron's salmon crashed a decade ago, Plant, who holds a degree in biology from Northern Michigan University, had no doubt the lake would eventually right itself and the fish would come back.
And fish did return — but they weren't the fish Plant or many others expected.
What has happened in the decade since the crash of Lake Huron's two dominant species — invasive Atlantic alewives and the giant Pacific salmon planted to gobble them up — is a remarkable story of nature's resilience. Efforts by lake managers to sustain the invasive alewives to keep the salmon fishing rolling had, for decades, pushed native species to the fringes.
But when the alewife dwindled and the salmon followed, there was an almost instant surge in native lake trout, walleye, smallmouth bass, chubs and emerald shiners.
"It all happened as soon as the alewives were gone," said Michigan Department of Natural Resources biologist Dave Fielder. "The natives started producing like crazy."
The remarkable result is that today the top of the Lake Huron food chain more closely resembles its natural self than anytime since the lamprey and alewives invaded in the mid-1900s.
"Lake Huron's fishery," said Jim Johnson, a retired biologist with the Michigan DNR, "is more stable and robust in the past four or five years than it has been in a long time."
It has everything to do with the disappearance of alewives, and little to do with Howard Tanner and Wayne Tody's grand salmon plan, crafted after alewives had over-run Lakes Michigan and Huron. Tanner said he was never interested in trying to bring back native species just because they were native. He wanted the best sport fishery he could fashion from the lakes — and for him that meant Pacific salmon.
And that led to managing the lakes in a manner that would preserve the invasive alewives for the salmon to eat.

The groundhog said six more weeks of winter from Feb 2.... he was wrong! It has been a lot of years, close to 20 since I was able to put some decent time in on the spring Great Lakes fishery. April is normally our second busiest month for river guiding, but the winter that wouldn't go away gave us some time for personal fishing.
Canadian kayak fishing guide Jeff Wall showcases his spring catch. Over 40 fish caught in six outings last spring. All were salmon or trout except one giant out of season walleye.
Steelhead, Coho Salmon, Brown Trout, Chinook Salmon, Atlantic Salmon, Walleye, Lake Trout were all caught and released over six separate days of fishing.
Long lining shallow crankbaits on light lines pretty much sums up the spring kayak fishing in Ontario for the Great Lakes region. We employed a variety of minnow baits, smaller spoons, and kwikfish style lures. Slow trolling with abrupt direction changes were the ticket in the open water trolling but crashing two lures thru the baitfish schools got us several doubles. I don't have to tell you how exciting that is in a kayak!
Please always consider best practices when heading out on the Great Lakes, especially when it is still winter. Better yet, hire a guide!

Hope you enjoy!
