Here, Lahontan cutthroats became a large (up to 1 m or 39 in) and moderately long-lived predator of chub suckers and other fish as long as 30 or 40 cm (16 in). The trout was able to remain a predator in the larger remnant lakes where prey fish continued to flourish, but upstream populations were forced to adapt to eating smaller fish and insects.
Other prey include adult terrestrial insects such as ants, beetles, spiders, grasshoppers and crickets, and aquatic items including crayfish, freshwater molluscs, fish eggs, shrimp and other crustaceans, and other fish. [5] [47] Generally, they adjust their diet and feeding behavior due to factors such as food availability, habitat, age, and size.
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. Young fish almost immediately begin feeding. [10]
