Nice Story About Sturgeon on the St. Croix River

In some cases you don’t have to pay such close attention. The big ones can leave a wake as they swim along, and some times of year they “breach”, or jump up out of the water.

This happened to me on the WI river, right next to my boat. Had to go home afterwards to change my shorts.

I was wondering what exactly they ate to be able to get so big

I understand anglers use gobs of crawlers on trebles to catch them

here's what Wiki says:

The lake sturgeon has taste buds on and around its barbels near its rubbery, prehensile lips. It extends its lips to vacuum up soft live food which it swallows whole due to its lack of teeth. Its diet consists of insect larvae, worms (including leeches), and other small organisms (primarily metazoan) it finds in the mud. Fish are rarely found in its diet and are likely incidental items only, with the possible exception of the invasive Round Goby.[4] Given that it is a large species surviving by feeding on very small species, its feeding ecology has been compared to that of large marine animals, like some whales, which survive by filter-feeding.[5]
