The goal of this study was to compare the possible locations, timing, and characteristics of potentially spawning shovelnose sturgeon (Scaphirhynchus platorynchus), blue sucker (Cycleptus elongatus), and associated species during the spring of 2007-2015 in the 149-km-long lower Wisconsin River, Wisconsin, USA, a large, shallow, sand-dominated Mississippi River tributary. Just like the pallid, shovelnose sturgeon prefer relatively deep water and moderate currents being that they are riverine aquatic creatures.

Like many fish, sturgeon require stable, moderate levels of oxygen to survive. Polluted waters have less available oxygen; in winter and midsummer, these oxygen levels may drop too low, resulting in death for the shovelnose sturgeon and other species. The shovelnose sturgeon Scaphirhynchus platorynchus, one of the smallest of the North American sturgeons, is endemic to the Mississippi, Missouri, and Ohio River basins (Keenlyne, 1997). The current makes it easier to find food, and their specialized siphon-like mouths act like vacuums, sucking up organisms buried in the benthic substrates. Most food is found over sand and gravel substrates. being eaten on occasion. In Pool 13 of the upper Mississippi River, shovelnose sturgeon were frequently located at water depths of 2-7 m (6.5-23 ft), where currents were .2-.4 m/s (.65-1.3 ft/s) at the bottom and .4-.7 m/s (1.3-2.3) at the surface (Hurley et al. shovelnose sturgeon was the most commonly sought species during creel surveys near the confluence of the Platte River, Nebraska.

In 1990, the U.S. Tactics for shovelnose are pretty simple - fish a natural bait (nightcrawlers have accounted for all the shovelnose I've ever encountered or seen caught) stationary on the sandy bottom in current.  Usually, this means using a heavy weight, like a Pyramid Sinker, to help anchor the rig in the shifting sand.  Unfortunately, the heavy weight often keeps this spirited fish from jumping, spinning, and tailwalking much during the fight, due to the encumbrance of the weight holding it down.  Fishing directly downstream from a boat can allow you to use a lighter weight and tackle, which brings out the frantic fight of this amazing fish and allows them to vault into the air at will.Â, Donald Perkins, Cast-N-Blast, Dr. Flathead, Corey Geving, roughfish identification, lifelist angling, fishing rare unusual fish species: bowfin burbot buffalo gar redhorse suckers carp, The Sturgeon Family from Fishes of Wisconsin (PDF, Becker), Sturgeon Identification video from the Missouri Dept.
