If you haven’t had a chance to visit Lake Superior State University’s fish cam, you should. When the fish start stacking up, it really is fascinating to watch.
The cam is located in the St. Mary’s River, the outlet that carries Lake Superior’s overflow into Lake Huron and on to the Atlantic Ocean. It’s also home to runs of steelhead in the spring, Atlantic salmon in the summer and chinooks — what’s left of them — in the fall.
Activity varies — it’s nature, after all — and it’s not unusual to see whitefish, suckers and other river inhabitants. Today it looks like the Atlantic salmon are making their way in from northern Lake Huron. Numerous fish swim right in front of the camera, giving you an up-close look at what life in the big lake does to a fish. You can see the clipped fins that tell what year the fish was stocked. Many have lamprey marks on them.
Worse, a disturbingly high number of salmon are actually carrying those vile bloodsuckers. I saw one fish with two lampreys on it.
There’s no two ways about it: Those are nasty critters. I mean, we know they’re out there. We know what they do. But seeing so many of them on fish is pretty disturbing. Efforts are ongoing to rid the Great Lakes of sea lampreys. But clearly there’s plenty of work to do.
