The Laramie fisheries and Aquatic Invasive Species crews helped inspect two separate loads of walleye from the Garrison National Fish Hatchery in North Dakota before stocking them into lakes and reservoirs in southeast Wyoming.

Because Wyoming hatcheries only raise trout, we receive walleye from North Dakota for Wyoming waters.  The walleye are raised in outdoor ponds, so the loads must be free of plants, invertebrates, tadpoles, and fish, or “anything that’s not a walleye” before stocking.

So biologists sort through the shipment by running the fish over white boards before stocking them. The white boards make it easy to see anything that doesn’t belong. “Garrison National Fish Hatchery does a really good job sending us clean fish, but we still need to go through them to ensure all is good,” said Laramie Region Fisheries Supervisor Bobby Compton.

Once cleared, 400,000 fingerling walleye were stocked into Grayrocks Reservoir in June. In August, Hawk Springs Reservoir and Wheatland Reservoir #1 each received 40,000 walleye. These walleye were slightly larger than the ones stocked in Grayrocks with the hopes that survival rates would increase by stocking bigger fish.
