The carp decreased in abundance from 1957 to 1959 at the upper and
middle Marais des Cygnes station and at the middle and lower Neosho
stations. Carp were more abundant in the Marais des Cygnes than in the
Neosho, although the largest number in any single collection was found
in one pool at the upper Neosho station in 1958.
Carp were taken most commonly in quiet water near brush or other cover.
At the middle Neosho station, collecting was most effective between the
hours of 6:30 a.m. and 12:30 p.m. and least effective between 12:30 p.m.
and 6:30 p.m. (Table 9, p. 402). Ripe males were taken as early as
19 April (16.1 inches, 19.4 inches T. L.) and as late as 30 July (16
inches T. L.) at the middle Neosho station. Ripe females were taken as
early as 19 April at the middle Neosho station (19.2 inches T. L.) and
as late as 7 July at the lower Neosho station (16 inches T. L.).
Young-of-the-year were taken first at the middle Marais des Cygnes on 8
July 1957. They were recorded on later dates at the upper Marais des
Cygnes and at the lower and middle Neosho stations.
