Lake Sturgeon fishing
Acipenser fulvescens. Heavy, torpedo-shaped body armored with five rows of sharp-edged bony plates (scutes), not scales.
Lake Sturgeon fishing uses a nightcrawler bottom rig or nightcrawlers on 40 to 50 lb line and a fairly stiff casting rod. Michigan's lake sturgeon are mostly reared at streamside facilities using a river's own water so juveniles imprint on it before release, raising the odds they return to spawn there as adults decades later.

Identification
- Heavy, torpedo-shaped body armored with five rows of sharp-edged bony plates (scutes), not scales.
- Long, tapering snout with four smooth barbels hanging in a row just ahead of a toothless, tube-like sucking mouth.
- Heterocercal (shark-like) tail with a longer upper lobe, and two small spiracles atop the head just ahead of the gills.
- Distinguished from the smaller shovelnose sturgeon by a short, rounded snout, smooth barbels, and spiracles, which shovelnose lack.
- Slate-gray, olive-brown, or black above with a pale underside; young fish show dark blotches that fade as the plates smooth with age.

Depth by season
Spring
Migrates into shallow, rocky river shallows to spawn from late April through early June, once water warms into the mid-to-upper 50s F.
Summer · 0–30 ft
Forages on the bottom of lake shallows under 30 feet and in deep river pools, locating food with its barbels rather than by sight.
Fall · 0–30 ft
Wisconsin's open hook-and-line rivers are fished this way each September.

Stocked behavior
Michigan's lake sturgeon are mostly reared at streamside facilities using a river's own water so juveniles imprint on it before release, raising the odds they return to spawn there as adults decades later. This is population rehabilitation, not a put-and-take fishery: females don't spawn until age 24 to 26.

Common mistakes
- Holding a sturgeon vertically by the head, gill covers or tail; Michigan DNR says not to hold a lake sturgeon in a vertical position.
- Undergunning the tackle; to catch a trophy sturgeon, use a fairly stiff casting rod and plenty of 40- to 50-pound test line.
