LARAMIE – Anglers looking for something to do this holiday weekend might want to try their luck at Crystal and Granite reservoirs, where the Wyoming Game and Fish Department stocked 750 brood cull rainbow trout earlier this week.
The fall spawning rainbow trout were culled from the breeding stock at Boulder Fish Rearing Station. They weigh between three and six pounds and average 16-18 inches. Crystal Reservoir received 500 fish and Granite Reservoir received 250.
As breeding stock, the fish produce between 2.5 and 3 million eggs per year. The eggs are shipped to fish hatcheries around the state where they are raised and eventually stocked into public waters. Normally, rainbow trout spawn or mate in the spring, but fall spawning rainbow have been manipulated to spawn in the fall. This allows a longer growing season for offspring before being stocked.
When broodstock fish reach three to five years old they are beyond their peak spawning production and are released into lakes and rivers in the state for anglers to enjoy. Crystal and Granite reservoirs receive some of the brood culls each year.
Ice is beginning to form on both of the reservoirs but is still unsafe and anglers are urged to use caution.
