The blunt-nosed minnow was common, and increased in abundance in both
rivers from 1957 to 1959. The largest numbers were found at the upper
Neosho station in 1959, and a large population also was present at the
lower Neosho station in 1959.
Pools having rubble bottom, bedrock, and small areas of mud were
preferred at the upper Neosho station. At the lower Neosho station the
fish was most common in quiet water at the lower end of a gravel bar.
The parrot minnow also was common in this general area; nevertheless,
these two species were seldom numerous in the same seine-haul,
indicating segregation of the two. The blunt-nosed minnow was taken
frequently in moderate current over clean gravel bottom, especially in
late summer, 1959, when _P. notatus_ increased in abundance as the
mountain minnow decreased.
