Lepisosteus platostomus Rafinesque. UMMZ 2. The shortnose gar is common in the Kansas River but seems less inclined than the longnose gar to ascend small streams.
Dorosoma cepedianum (LeSueur). UMMZ 2; DM 1. Gizzard shad.
Carpiodes velifer (Rafinesque). UMMZ 2. This record for the highfin carpsucker is based on a single specimen (UMMZ 63182). It was re-examined by Bernard Nelson who stated (personal communication) "The dorsal fin is broken and the 'pea-lip' smashed. A trace of the 'pea' is still discernible. The body is deeply compressed and other measurements agree with [those of] C. velifer. It was identified as C. cyprinus at first, but later changed by Hubbs." C. velifer probably was more abundant in Kansas during and before the early 1900's than at present. Several early records of the species are available, but the only specimen obtained in Kansas in recent years was captured in the Neosho River by Deacon in 1958.
Moore (1957:80) states that C. velifer occurs in the clearer rivers and lakes of the Mississippi valley, westward to Nebraska and Oklahoma. The almost complete disappearance of this species from Kansas probably resulted from an increase in turbidity, of the rivers, accompanying settlement and cultivation of the land.
Carpiodes carpio carpio (Rafinesque). KU 5, 12, 15; DM 1, 16, 21, 37. The river carpsucker occurred at stations scattered throughout the drainage, except in the smallest creeks. The largest numbers were found in the lower mainstream.
Ictiobus cyprinella (Valenciennes). KU 10; UMMZ 2; DM 1. The big-mouth buffalo was taken only near the mouth of the river; black buffalo, Ictiobus niger (Rafinesque) and smallmouth buffalo, Ictiobus bubalus (Rafinesque), possibly also occur there but were not taken in our survey.
Catostomus commersonnii commersonnii (Lacépède). KU 4, 8, 14; UMMZ 1, 5; DM 10, 11, 15, 16, 21, 23, 25, 26, 27, 29, 34, 42. The white sucker occurs primarily in upstream-habitats in the Wakarusa Basin.
Moxostoma aureolum (LeSueur). KU 15; DM 1. The northern redhorse was taken only in downstream portions of the basin. Minckley and Cross (1960) regard specimens from the Wakarusa River as intergrades between M. a. aureolum and M. a. pisolabrum.
Cyprinus carpio Linnaeus. KU 9, 12, 15; DM 1, 2. The carp, though most abundant in downstream situations, probably occurs throughout the drainage and is a potential pest in all impoundments likely to be constructed in the basin.
Notemigonus crysoleucas (Mitchill). KU 9; DM 9, 27, 33, 41. The golden shiner was found only in tributaries.
