Tui chub (Siphateles bicolor)

Little information is available regarding the sensitivity of tui chub to climate change. Tui chub inhabit lakes and slow-moving pools in riverine environments, spawning and rearing in shallow areas in spring and summer. Similar to other minnow species, they are likely sensitive to climate-driven shifts in rearing and spawning habitat near stream and lake margins (e.g., reduced habitat due to reduced spring/summer low flows or lake water levels caused by reduced snowpack, earlier snowmelt, shifting precipitation regimes and/or drought). Wildfire may also affect streamside vegetative cover and rearing habitat, as young tui chub are typically found close to shore in areas with heavy vegetation. Tui chub are also likely sensitive to increasing water temperatures, as yearly spring temperature increases cue spawning timing.
