This species is extremely
wide ranging and is stable and secure throughout its range. It occurs throughout the
Mississippi River basin except for the Tennessee and Cumberland River basins. The range
extends from western New York to Minnesota to Montana and south to Arkansas and western
into eastern Kansas and Nebraska. It is found as far west as the eastern Colorado border
and in Montana and is widespread throughout the interior of Canada, including the western
Hudson Bay drainage.
- Comments:
The fatmucket is sexually dimorphic in shape. With age, females develop into a
hatchet shape, the anterior end being much smaller than the posterior end. This difference
is to provide more room to brood the eggs in her gills while the male’s shape with
age is more symmetrical. Like other Lampsilis mussels, the female displays a large lure to
attract host fish. This lure is less fish-like than others within the Lampsilis group yet
still attractive to a variety of host fish. The fatmucket is more likely found in smaller
streams and can be found in some reservoirs.
- Fish Hosts:
white sucker, bluegill, orangespotted sunfish, smallmouth bass, largemouth bass,
white crappie, black crappie, walleye and sauger
