Jackson - This Snake River cutthroat trout is one of many captured in a fish trap that is set up on a tributary of the Snake River. Every June for the past 52 years, Game and Fish has recorded the number of mature Snake River cutts that return to spawn at the same location each year. This year was near the average catch at just over 200 fish. Last year was an all-time high at over 600 fish, likely boosted by high spring run-off. Periodically, the statewide spawning crew will collect eggs from females and/or milt from males to infuse new genetics into the brood stock at the Auburn Hatchery in Star Valley. This brood stock at Auburn is the sole source of Snake River cutthroat trout that are stocked in Wyoming and traded to other states for other species of fish. Cutthroat trout begin to spawn at 4 to 5 years old, but unlike Pacific salmon, they don't die after they spawn. This is yet another way fish biologists for Game and Fish monitor the Snake River cutthroat trout population in the Jackson Region.
