Bowcutt / Cutbow Trout

The Bowcutt (or Cutbow) is a sterile hybrid trout species made from cross-breeding a Rainbow Trout and Cutthroat Trout. Many times, they will look like a Rainbow Trout with larger spots that are situated toward the rear of the fish. It also tends to have the red slash under its jaw that is characteristic of the Cutthroat Trout. The species is produced by Nevada hatcheries and stocked throughout many lakes and reservoirs in northern Nevada. A Bowcutt is created with a paternal Rainbow Trout while a Cutbow had a Cutthroat Trout as a father.

Habitat & Range

Because it is predominantly stocked as a sterile hybrid, it has no native range. Bowcutts (or Cutbows) are produced in Nevada hatcheries and stocked throughout many larger lakes and reservoirs in northern Nevada. Natural Bowcutts can occur where Rainbow Trout and Cutthroat Trout coexist, usually in streams. This is normally referred to as introgression and is a leading cause for the reduction and/or elimination of Cutthroat Trout from their native range throughout the west.

Threats

  • Bacterial Cold Water Disease
  • BKD- Bacterial kidney disease
  • Diseases in Hatchery Stocks: IHN-Infectious hematopoietic necrosis
  • VHS-Viral hemorrhagic septicemia
  • Whirling Disease

Natural History

Cutbow/ Bowcuts are native to the Columbia River. They were introduced as a hatchery fish in Nevada. Since they are a rainbow trout hybrid, they eat mostly small fish and invertebrates found in and around brush.

Fun Facts

Since Cutbow/ Bowcuuts are a hybrid, it makes thm almost immune to whirling disease.
