If you’re not from the midwest, chances are you’ve probably never heard of a coaster brook trout.  The term ‘coaster’ refers to brook trout that spawn in tributaries of Lake Superior, but spend a good chunk of their time growing along the shores of the big lake.  While once believed to be a unique strain of brook trout, the latest research has shown that coaster brook trout are genetic equals to their stream resident brothers, but their difference in habits explain the vast difference in size.  Coasters can grow up to 28 inches and 1-3 pounders are commonly caught.  Their ability to capitalize on abundant food in the lake influences their higher growth rates.

Coasters have been declining for years, and both the Wisconsin DNR and the Michigan DNR have been working to restore the fish to their previously high numbers.  Reasons for decline include stream habitat degradation, sea lamprey invasion and overfishing.  For more information on the coaster brook trout, see:
