The blue sucker was taken rarely in the Neosho River and not at all in
the Marais des Cygnes in my study. Cross (personal communication)
obtained several blue suckers in collections made in the mainstream of
the Neosho River in 1952; both young and adults occupied swift, deep
riffles. The species seemingly declined in abundance during the drought,
and at the conclusion of my study (1959) had not regained the level of
abundance found in 1952.
