Chemical Characteristics of Side Channels in the Madison River (Montana) Drainage
Content Description
Abstract: Multiple measurements of temperature, dissolved oxygen, pH, and conductivity were taken for each side channel in the Madison river.
Purpose: These data were collected as part of a larger study that examined the relationships among characteristics of the environment, Tubifex tubifex populations, and rainbow trout whirling disease risk in the Madison River (Montana).
Supplemental Information:
Relevance of this dataset to fisheries managers:
Dominance of fine sediments and low water temperatures were associated with a high site-specific contribution to whirling disease risk.
Application of dataset:
The site-specific contribution to whirling disease risk and density of infected T. tubifex were negatively related to water temperatures, and low maximum water temperature was the best single predictor of the site-specific contribution to whirling disease risk. In other studies, the severity of infection in trout was positively correlated to water temperatures in Willow Creek, Montana, and in three drainages in Idaho (Baldwin et al. 2000, Hiner and Moffitt 2002).
Water temperature affects the development of the parasite in rainbow trout and T. tubifex (Halliday 1973, El-Matbouli et al. 1999, Blazer et al. 2003, Kerans et al. 2005). Furthermore, high water temperatures (25
308C) can inhibit M. cerebralis infections of T. tubifex in the laboratory (El-Matbouli et al. 1999). Thus, water
temperature may influence infection in T. tubifex, and thus whirling disease risk.
While conductivity has been shown to be related to stream productivity and M. cerebralis infection in other studies, the present study did not indicate this relationship.
