Lahontan redside

Lahontan redsides are noted for their breeding colors, consisting of a bright red stripe with a yellow border on each side.

The Lahontan redside lives in the benthopelagic, freshwater environment.

Lahontan redsides living in lakes tend to shoal and forage by swimming in the littoral zone. A diet study in Lake Tahoe found that these fish feed on both benthic and surface organisms, though primary food targets may vary highly throughout the day. More

Nonindigenous Occurrences: The Lahontan redside has been recorded from various locations in California outside its native range, in the Sacramento River drainage (Page and Burr 1991), including Miller Lake on Mill Creek-Rubicon River system (Kimsey 1950) and Bucks Lake and Warner Creek, both in More

The Lahontan redside has managed to ‘jump’ from the Lahontan Basin into the adjacent upper reaches of the Sacramento River drainage, probably in the Lake Tahoe or Honey Lake areas, but otherwise has remained isolated. More
