Sicklefin Chub
(Macrhybopsis meeki)
Sicklefin Chub
In Montana, sicklefi n
chub are found in
the middle and lower
Missouri River and
lower Yellowstone River.
They seem to prefer
deeper water and sandy substrate. Spawning
occurs in main channel areas of large turbid
rivers, which they inhabit. 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; and
removal of wild individuals
used for baitfi sh. Conservation
strategies include: developing
conservation practices on
large rivers in Eastern Montana to include
sustainable irrigation; educating public
on the necessity of native species; and
considering a management plan for the
sicklefi n chub or including it in another
comprehensive taxonomic plan.
