I was recently publicly challenged in regard to my opposition in this column to stocking nonnative lake trout over rare wild native Arctic charr in Green Lake. The person behind the challenge, a well-known outdoor writer, defended their position by homing in on hybridization, or what they believe is a lack thereof, as the reason the stocking was not a concern. To be fair, I used hybridization between introduced lake trout and native Arctic charr — the cause of the loss of Arctic charr of New Hampshire and Vermont — as one of the reasons the lake trout stocking on Green Lake in Hancock County should be suspended.
