​Fishing Fact of the Week

​​

Brown Trout Hybrids

Did you know that brown trout rarely form hybrids with other fish species, and if they do, they are almost invariably infertile? 

One such example is a tiger trout which is a hybrid species between a brown trout and a brook trout. Tiger trout can be produced reliably in hatcheries. This is done by fertilizing brown trout eggs with brook trout milt and heat shocking, causing the creation of an extra set of chromosomes and increasing survival rates from 5% to 85%. 

Endangered and Threatened Fish Species

Did you know that Colorado currently has 5 fish species that are considered Federally Threatened or Endangered?

These fish species include the Bonytail, Colorado Pike Minnow, Greenback Cutthroat Trout, Humpback Chub, and Razorback Sucker. In addition to federally protected fish, Colorado also has 18 fish species that are considered endangered or threatened through ​state protection. View the full list here​.
