Lepisosteus osseus oxyurus (Linnaeus): Stations A-1, W-2, W-3, G-2, G-3, G-4, C-1, C-2, C-3, C-5, C-8.
Of 34 longnose gar taken, 27 were young-of-the-year. The latter were from shallow isolated pools (bedrock bottom at C-1, C-3, C-4; gravel bottom at C-6). At station W-1 in moderate flood conditions several young-of-the-year were found in the most sheltered water next to the banks.
The longnose gar was found only in the lower parts of the streams surveyed (but were observed by me in smaller tributaries of these streams in years when the streams had a greater volume of flow). A preference for downstream habitat is suggested in several other surveys: Cross (1950:134, 1954a:307) on the South Fork of the Cottonwood and on Stillwater Creek; Cross and Moore (1952:401) on the Poteau and Fourche Maline rivers; Moore and Buck (1953:21) on the Chikaskia River.
Lepisosteus platostomus Rafinesque: One shortnose gar (K. U. 3157) has been taken from the Arkansas River in Cowley County. This gar was taken by Mr. Richard Rinker on a bank line on April 10, 1955, at station A-3.
Dorosoma cepedianum (Le Sueur): Stations W-3, G-4, C-4, C-5, M-1, E-1, E-4.
In smaller streams such as the Elk and Caney rivers adult gizzard shad seemed scarce. They were more common in collections made in larger rivers (Walnut, Verdigris, and Neosho). In impoundments of this region shad often become extremely abundant. Schoonover (1954:173) found that shad comprised 97 per cent by number and 83 per cent by weight of fishes taken in a survey of Fall River Reservoir.
Carpiodes carpio carpio (Rafinesque): Stations A-1, A-2, A-3, W-3, G-1, C-3.
Hubbs and Lagler (1947:50) stated that the river carpsucker was "Mostly confined to large silty rivers." Of the stations listed above C-3 least fits this description being a large shallow pool about ⅓ acre in area having bedrock bottom and slightly turbid water. The other stations conform to conditions described by Hubbs and Lagler (loc. cit.).
Carpiodes velifer (Rafinesque): SBS. Three specimens of the highfin carpsucker (K. U. 177-179) were collected on July 11, 1912, from an unspecified location on Elk River in Elk County.
Ictiobus bubalus (Rafinesque): Stations W-3, G-1, G-2, C-1, C-3, C-4, C-6, E-1, E-2, E-3.
