|Our Best Ports For Brown Trout|

Michigan’s Great Lakes brown trout fortunes rest solely on planted fish. While an estimated half or more of the Chinook salmon in lakes Michigan, Huron and Superior are naturally reproduced fish, spawning by lake-run brown trout contributes little to the fishery. Great Lakes brown trout are basically a put-and-take fishery. The last few years though, there hasn’t been much “take.”
The Great Lakes brown trout fishery exploded during the mid 1990’s when fisheries managers introduced new strains of lake-run brown trout that were thought to be more suitable to the open waters of the Great Lakes. Strains such as the Seeforellen and Wild Rose thrived when they were first planted. The new strains were hailed as the saviors of the Great Lakes brown trout fishery and biologists rejoiced with the hope that a blossoming fishery was in the making. But what many people failed to realize was that the new plants also coincided with several years of prolific alewife abundance. The fish gorged on the plentiful baitfish and grew to trophy proportions. Survival of the naïve young trout was excellent. Conditions were ideal for the new and improved version of Salmo trutta.
When I asked Alpena Fisheries Research Station biologist Jim Johnson if anything had changed with regard to the prospects for brown trout on Lake Huron he said, “Things are always changing. Unfortunately, it’s not always for the best. It’s pretty hard to plant anything right now and expect them to do well because of the lack of baitfish. The brown trout we do plant just become food for the predators.” In recent years fisheries personnel have planted upwards of 100,000 browns in the waters of Thunder Bay and Lake Huron and the return on the investment has been dismal.
Biologists on Lake Huron have tried planting brown trout at night, tried planting them offshore, tried holding them until the fall to plant larger fish. Nothing has worked and they are running out of options. The latest strategy is to move the brown trout plants farther to the north at Rockport and away from cormorant colonies. Most feel they are grasping for straws. The one bright spot in this dark cloud that is hanging over the brown trout is that the ones that survive are getting big. “The brown trout have a gauntlet to run before they make it to catchable size,” said Johnson. “The good thing is that the ones that make it are doing extremely well by growing fat on gobies.” The exotic gobies have overrun native species like sculpin and emerald shiners and the brown trout are taking advantage of it.
“The Thumb has some brown trout,” offered Johnson, “but the baitfish situation there is the worst. The lake off the Thumb is subject to cold water in the winter because the wind there really mixes the water and alewives do not winter well in those kind of conditions.” “There might be more browns in the waters off the Thumb than many people think,” suggested Southern Lake Huron Management Unit fisheries supervisor Jim Baker. “Generally, fishing for browns is slow off the Thumb and they don’t turn up in large numbers, but I think a lot of it is guys just don’t target them. I think there’s fish there to be caught, but people are just not trying to fish for them.”

When I asked Central Lake Michigan Unit fisheries biologist Mark Tonello what kind of season anglers enjoyed for brown trout on Lake Michigan last year he was brutally honest. “I didn’t hear a lot of good things,” was his reply. Even though Lake Michigan certainly has better spring brown trout fishing than Lake Huron right now it was not a banner year. “The charter boat data shows that 2003 was the poorest year since 1997,” said Tonello. “I know that 2004 was a little better, but not great.”
One advantage brown trout do have on Michigan’s west side is that they can be planted in the drowned river mouths which are warmer and dark and help jumpstart the browns and shield them from predators. In recent year fisheries managers have tried to plant browns as early as possible in the spring so that they can get acclimated before the migrating cormorants show up. Anglers were encouraged because they did catch some of the 2- to 4-pound footballs that are the result of last year’s plant. Some of the fish are surviving. The question is, “How many?”
Biologists are in disagreement whether the poor brown fishing is from cormorant predation or a lack of baitfish. “Planting of brown trout is pretty significant,” said Charlevoix Fisheries Research Station fisheries biologist Dave Clapp. “We wouldn’t have a fishery if we didn’t.” Lake Michigan brown trout plants seem to do best at Ludington, Manistee and Frankfort and that’s where anglers typically find the best spring brown trout action. The drowned river mouth lakes that spill into the big lake at these ports warms near shore waters and concentrates browns and baitfish.
Lake Michigan browns are likely growing fat on gobies or spot-tailed shiners. “Emerald shiners are pretty much gone from the near shore water,” claimed Clapp. “Darters and sculpin are getting hammered by the gobies too.”
The prospects for brown trout this spring don’t look too rosy. But the just chance to get out on the big lake and enjoy a warm spring day is often reward enough. If you happen to box one or two of those football browns, it’s a real bonus.
