lifespan to similar to other darters, which is typically a few years. Management No management plan is in place for this species, as it not listed as threatened or endangered in Tennessee or federally. Because population statistics of this fish are unknown, it is hard to know the state of current populations and if they are in threat or could become so. As with any aquatic species it is important to mitigate human effects on river dynamics to reduce damage to populations. To ensure the sustainability of E. bison and other fish like it, the effects of erosion due to urbanization and agriculture and the construction of dams need to be controlled. Siltation is a huge issue for small benthic fish such as these darters' it can cause physical ailments and behavioral changes. References Etheostoma Fish described in 1997
