Triactinomyxons (TAMs) release by Tubificids Collected from the Madison River (Montana)Entry ID: MSU_17
Abstract: Oligochaetes were collected from six side channels of the Madison River (Montana) and observed for TAM release. This dataset shows the number of the tubificids with morphology similar to T. tubifex that were observed releasing TAMs. Tubificids releasing TAMs were counted as "infected," and the number of infected tubificids was calculated for each collection period and side channel. These data were used in conjunction with density data from benthic cores to determine the density of infected T. tubifex (as described in the paper).
These data suggest that the dynamics of M. cerebralis infections in the Madison River are driven both by the abundance of T. tubifex and the availability of infectious myxospores and that the relative importance of each may vary among the hot spots.
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).
Whirling disease is widespread in the Madison River and the involvement of three organisms suggests no easy management solution. Management ... solutions to completely remove M. cerebralis from the Madison River are unlikely to be successful. However, our increased understanding of the spatial and temporal patterns in M. cerebralis infections can help direct our management decisions. For example, encouraging practices that reduce the amount of fine sediments entering the river could result in lower densities of T. tubifex releasing TAMs. Additionally, practices such as management of the dam to allow increased spring flow levels to increase the velocity of the river near times of critical rainbow trout spawning and rearing could decrease the infectiveness of M. cerebralis.
In addition, locating hot spots and subsequently implementing management strategies aimed at eliminating or reducing the source of M. cerebralis may be vital to reducing the impact of whirling disease throughout a river system.
