Nothing fishy going on here!

University of Michigan researchers are part of a multi-institution team working to restore lake sturgeon, which were once common in the Great Lakes, by building rock spawning reefs in two Detroit-area rivers. The latest set of reefs was completed last month in the Detroit River near Belle Isle. Learn More: http://myumi.ch/aZEvE

I'm sure there's more science going on that what meets my untrained eye. To me it seems they're dumping tons of rocks in the river to give lake sturgeon a sweet love shack. Also, good hiding spot from the other critters that eat the baby sturgeon.

It's painfully obvious I'm not a marine biologist.

But it doesn't take a fish doctor to know you need a nice place to call home and if these acres of reefs give the lake sturgeon a nice place to make babies then right on.
