Coaster Brook Trout Genetics, Life History, and Management with Minnesota DNR’s Nick Peterson

In this episode I talk to Minnesota DNR scientist Nicholas Peterson who specializes in managing Lake Superior Native Coaster Brook Trout. You will learn alot about the amazing life history of coaster brook trout, their resilience, genetics, and many many fisheries management lessons/initiatives we can apply here in Pennsylvania. We may not have Lake Superior in Pennsylvania but we have deep lakes connected to brook trout streams that have similar adfluvial life histories. We can learn a lot from Minnesota DNR’s focus on brook trout conservation genetics, thermal refuge mapping, stocking reform, university/non-profit brook trout research partnerships, and just generally their commitment to so much more than just stocking hatchery trout. We will also talk briefly about how brook trout often are found living in places they “shouldn’t be” such as streams in the upper 70’s and other places we don’t think they can survive yet have thermal micro habitat. We also talk about Nick’s experience holding 25 inch coaster brook trout at night electro surveying in the livht of the Aurora Borealis(northern lights). There is plenty of discussion about historical human impacts that harmed Minnesota coaster brook trout as well as the 2018 recovery of coasters that was helped along by forward thinking coaster brook trout harvest regs enacted in 2006. Minnesota’s north shore is a magical place with magical fish!
