a 150lbs sturgeon was caught on the government docks in north bay a couple years back. It was all over the papers up there. it took 6 guys on the rocks to lift it up onto the docks and they released it after a few pics.
They are huge prehistoric fish but if the muskie is a fish of a thousand casts then the sturgeon would be the fish of a billion casts. Your better to try for a salmon in lake ontario. The burn in your forearms will leave you with a memory that is hard to forget!
