FISH-FAUNA OF THE UPPER NEOSHO RIVER
Collections at the upper Neosho station were more intensive than at any other station, especially in 1959. Rotenone was used in the summers of 1957, 1958 and 1959, to obtain large samples of the population in one section of the stream. In September, 1959, the shocker was used in other sections in order to estimate populations in particular pools and riffles, to measure variability in the fauna between areas having slightly different habitat, and to record movement of marked individuals in a short section of the stream.
