We're a project of the Knight Center for Environmental Journalism at Michigan State University. I just watched a special on tv that was stating how grayling are gone from the great lakes which is what made me look online. … In Montana, both life forms of Arctic grayling exist, lake dwelling (lacustrine or adfluvial) and river dwelling (fluvial). From what I read online it is saying they have been gone for 50+ years, but I am pretty darn confident I caught one of these in the late 80s.

Yes that did happen, but amazingly these small Grayling, just days old, showed the instinct to hide in the stones from the predator Brook Trout. The MI DNR has done studies on both species and, at least at the time, decided that it was not worth the expense and effort to continue the programs. Like many, fish are visual predators and have excellent eyesight; in fact, their vision is very close to ours. The master’s thesis of a graduate student studying under Infante is one of the reasons the tribe is focusing on this section of the Manistee, Holtrgren said. The articles’s link to the 1992 report didn’t work, but readers can find it at: Biologists admit catches of grayling, stocked last in 2000, are exceptionally rare, though. Probably because of the river scenery and the spectacular view of the upper falls. It is debated that the Alaska grayling is one of the best eating freshwater fish in the world. Similar to Harold I would rather see an attempt towards promoting native fisheries than the exotic. Also, if you read the grayling pdf from the State of Michigan there was not much assessment on the reintroductions but much speculation. Having fished throughout the U.S. and Canada, I dare say that Michigan has some great native fish species that deserve our support–and not just by way of fishing for them, but by seeking that they return to their rightful place in the Great Lake’s ecosystem.

But the Little River Band of Ottawa Indians is partnering with Michigan Technological University biologists Nancy Auer and Casey Huckins, looking into the possibility of bringing them back. Better yet, just give the $200,000 to the DNR for the GLS Muskellunge program until the LRBOI can be more responsible with the use of scarce funding.
