So they’re a lot different from other fish in the Great Lakes. They don’t have a normal skeleton. Instead, they’ve got these bony plates on the outside of their bodies, called scutes. They have no fish scales.</p><p>“They’re kind of rubbery on the outside and they are extremely docile, unlike the fish with the flopping and all that,” said Ron Clark. He’s with the <a href="http://kazoosturgeon.org/">Kalamazoo River Sturgeon Restoration Project </a>out of New Richmond.</p><p>“They let you move them; they let you hold them,” Clark said.

And today, Dustin Dwyer has a story about one of the most fascinating fish in the Great Lakes. Sturgeon have been around for more than 100 million years.&nbsp; Each fish can live more than a hundred years, weigh more than a hundred pounds and stretch eight or nine feet long. But sturgeon have also been the target of overfishing and poaching. Dustin caught up with one group in northern Michigan that&#39;s trying to save them.&nbsp; Here&#39;s his story:</p><p>So about a month or two ago, I was sitting along the bank of the Black River, way up near Onaway. And I was next to Jesse Hide, who has lived in this area all his life, and watched sturgeon all his life. We were keeping an eye out for sturgeon heading up the river to spawn.</p><blockquote><p>&ldquo;There&#39;s one coming up right there ... he&#39;s coming back down now.&rdquo;</p></blockquote><p>The long, spear-like fish occasionally poke their heads out of the water, like a submarine coming to the surface.</p><p> Tue, 28 Jun 2011 14:18:32 +0000 Rebecca Williams 3045 at http://michiganradio.org Swimming Upstream: Fending off sturgeon poachers (part 4)
