Ecology and management of channel catfish Ictalurus punctatus and flathead catfish Pylodictis
olivaris populations in the middle Missouri River, NE.
Otoliths were reported to be the most reliable ageing structure in a number of fish species such as Chelidonichthys kumu (Staples, 1971), Capoeta capoeta umbla (Ekingen & Polat, 1987), Trachurus trachurus (Polat & Kukul, 1990), Pylodictis
olivaris (Nash & Irwin, 1999), and Ictaluruspunctatus (Buckmeier et al.

The river was exploited for catfishes, primarily with trotlines and limblines, and for flathead catfish Pylodictis
olivaris, a highly predatory catfish (Jackson 1999), the trotlines and limblines were baited with live bait.
Sporadic individuals of other species (threadfin shad, Dorosoma petenensr, bluegill, Lepomis macrochirus; largemouth bass, Micropterus salmoides; western mosquitofish, Gambusia affinis; an undetermined ictalurid catfish, either channel catfish, Ictalurus punctatus, or flathead catfish, Pylodictis
olivaris) have been encountered over the years and removed; none were known to be present during the time of our study.

The species with the greatest positive percentage of change from historical to contemporary surveys included shorthead redhorse Moxostoma macrolepidotum (historical percentage of occupied sites, percentage of change in site occurrence from historical to contemporary surveys; 4%, 443%), bluegill Lepomis macrochirus (5%, 410%), flathead catfish Pylodictis
olivaris (3%, 380%), and shortnose gar Lepisosteus platostomus (3%, 360%; Table 2).
It is uncertain whether Jordan's specimens represent Ameiurus natalis or Pylodictis
olivaris, both of which are native to the Etowah River (Mettee et al.
