Notable details

  • The golden trout is California's official state freshwater fish, designated in 1947.
  • They are native only to the South Fork Kern River drainage in the Sierra Nevada, living above roughly 6,900 feet elevation.
  • Their vivid gold flanks, crimson lateral stripe, and spotted fins make them among the most colorful freshwater fish in North America.
  • Wild golden trout rarely exceed 10 inches because cold, nutrient-poor high-altitude streams severely limit growth.
  • They readily hybridize with rainbow trout, which threatens genetically pure populations throughout their native range.
