anglers. That species has a thick black stripe along its sides
that runs from the tip of its head to its tail.
The Redfin Shiner was once more common in
Pennsylvania than it is today. During the 1930s, noted
ichthyologist E. C. Raney reported it to be "common to
abundant locally in warm water creeks and small rivers
with a mud and sand bottom in quiet water." He collected
it at seven different locations including Otter Creek and
Shenango River, Mercer County, and small streams in
Lawrence and Venango counties. It has not been seen in any
of these streams since that time.
Redfin Shiners are attracted to the Green Sunfish's nest by the
male Green Sunfish's activities and are then stimulated to spawn
by the scent of milt and ovarian fluid from spawning sunfish
in the water.
Raney also captured it in Cussewago Creek, Crawford and
Erie counties, where it still exists today. It has more recently
been found in Conneaut Creek, Erie County, but now
inhabits only half of its original known range.
The reason for the decline is unclear. Although some
biologists state that this species requires clear water, others
note that it is found in turbid and muddy streams. In
Pennsylvania, Cussewago Creek is somewhat turbid and
during periods after rainfall gets downright muddy. The
streams where it is found in the Conneaut Creek system are
relatively clear. So, it is unlikely that increased siltation alone
caused their disappearance in the Shenango River drainage.
Based on its current rarity, Pennsylvania Fish & Boat
Commission has listed the Redfin Shiner as endangered
in Pennsylvania. The remaining populations appear to be
somewhat stable, but this fish is by no means common or
abundant, as Raney had reported.
Additional research is needed to determine what
has caused the decline of the Redfin Shiner. With that
information, it may be possible to enhance the status of
the existing populations. Additionally, if the factors that
contributed to its loss from the Shenango River system
have been reduced or removed, it may be feasible to
reestablish new populations and recover the Redfin Shiner
in that drainage.
Returning this miniature jewel to its historic waterways
would be a true conservation success story.
The female Redfin Shiner lacks the bright colors of the male.
