Lake trout stocking

A fishy tale:

Hansen with lake trout, via Charles C. Krueger

In the 1800s, lake trout were abundant in Lake Superior. Then, in the early to mid 1900s…

Hansen: “… populations began to decline rapidly.”

That’s biologist Michael Hansen. He says overfishing and predatory invaders known as sea lampreys were to blame. By the time an effective way to control lampreys was discovered, the damage was done.

Commercial fisheries closed, and efforts to restock lake trout began.

Hansen: “That stocking program led to a build up of populations that then reproduced and have now become self-sustaining…”

…making lake trout plentiful again. How’s that for a superior ending?
