Can brook trout breed with brown trout?
Brook trout may hybridize with brown trout to produce infertile tiger trout. In Lake Superior, large brook trout will migrate into streams in the fall to spawn. This type of life history strategy is called adfluvial.
Are all tiger trout sterile?
The tiger trout (Salmo trutta × Salvelinus fontinalis) is a sterile, intergeneric hybrid of the brown trout (Salmo trutta) and the brook trout (Salvelinus fontinalis). The fish is an anomaly in the wild, with the brook trout having 84 chromosomes and the brown trout 80.
Can you eat Cutbow trout?

Why are farmed trout sterile?
Farmed trout stocked into rivers must be infertile (triploid) to prevent them breeding with wild trout. …
Do stocked lake trout reproduce?
Fertilized eggs are pressurized treated to become triploid so they cannot reproduce. Tiger trout are not pressurized as they are already sterile. Over two million fry and juvenile adult trout (8 to 18 months old) are stocked into Alberta’s waters from spring to fall each year.
Can hybrid trout reproduce?
Both of the hybrids are sterile, however, the rainbow cutthroat cross or hybrid is fertile. This is where the problem lies with hybrids that are fertile. If they breed in high enough proportion with either of the pure strain parent species then the purity is lost and it can erode the effective quality of the hybrid.
How do you tell if a trout is a Cutbow?
White Tipped Fins – White tipped fins on the bottom of the fish are not on Cutthroat trout. If a trout has these white tips, it is either a rainbow, or a cut bow trout. If the trout features the normal coloration and spots of a cutthroat with the white fins, then it is a cut bow trout.
How do you identify Cutbow?

What is the difference between a rainbow trout and a cutthroat trout?
When asked to define the difference between a Rainbow Trout and a Cutthroat Trout, a biologist would tell you that although both species have different origins and ranges, they are both members of the same family and genus Salmonidae oncorhynchus but, that they are also two distinct and different species.
Where do cutthroat trout come from naturally?
They do occur naturally in the wild in areas where the native range of rainbow trout, and cutthroat trout overlap. They can also occur where rainbow trout are stocked in areas of cutthroat trout. This was a common occurrence in the late 1800’s.
What is the native range of rainbow trout?
For instance, Rainbow Trout are classified by taxonomists as Oncorhynchus mykiss and their native range extends from the Kamchatka Peninsula in Russia, east along the Aleutian Islands into most of Alaska, and then south along the Cascade, Sierra-Nevada, and the Rocky Mountains all of the way into northern Mexico.
