"Long dedicated to the trout that sustain its commercial fishing, the Keweenaw Bay Indian Community started rearing fish that historically couldn't survive in much of frigid Lake Superior. "We started raising walleye at the hatchery in 2005," said Evelyn Ravindran, a natural resource specialist with the tribe. "We see them more and more."

And so the tribe, sensing a business opportunity, added that fish to its hatchery. " (Quoted from article)
