Sturgeon Chub
(Macrhybopsis gelida)
Sturgeon Chub
Sturgeon chub are
found in the Lower
Yellowstone and tributaries
including the Tongue and
Powder Rivers, as well as
the mid and lower Missouri
River. Sturgeon chub prefer
sites having moderate currents and depths,
and sand or rock substrates. Conservation
concerns include: habitat alteration by dam
operations, reduced turbidities and/or altered
temperature and fl ow regimes; channelization
of the Missouri River due
to irrigation operations;
removal of wild individuals
used for bait fi sh; and
constriction of range
due to low stream fl ows.
Conservation strategies include:
developing conservation practices on
large rivers in eastern Montana; educating
public on the necessity of native species; and
repopulating tributaries such as Teton and Milk
Rivers to establish periphery populations.
