In lake habitats such as Walker Lake, Tui chub are heavily preyed upon. They are a key prey item for the Lahontan Cutthroat trout in Walker Lake. Additionally, Tui chub are preyed upon by fish-eating birds. [15] Tui chub diet is varied; young fish eat mostly invertebrates, adding plant material and especially algae as they mature.
