Tiger Trout

The Tiger Trout is a sterile hybrid of the Brown Trout and the Brook Trout. The name derives from the pronounced worm-like vermiculation pattern, which evoke the stripes of a tiger. The hybrid itself is unusual in that the parents are members of different genera.

Habitat & Range

Because it is predominantly stocked as a sterile hybrid, it has no native range. Tiger Trout are produced at various hatcheries throughout the western United States for stocking in lakes and reservoirs. Tiger Trout are stocked throughout northern Nevada in lakes, reservoirs, and streams in an effort to give anglers a unique catch. Although rare, a few instances of natural Tiger Trout have been documented where Brook Trout and Brown Trout coexist.

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

Tiger trout are a hybrid of brown trout eggs and brook trout milt. The special process creates an extra chromosome, which created survivability and a faster growth rate. Tiger trout are found in 22 mountain streams and reservoirs.
