The Utah Division of Wildlife Resources has an unorthodox method of stocking lakes in the Boulder Mountains with trout.

In years gone by, the fish were loaded into containers at hatcheries, before being taken to remote areas on horseback.

Now, the fish are flown over the lakes in a plane, before being unloaded mid-air.

The Utah DWR says this causes less stress to the fish, adding that 95% of the trout "easily" survive the drop.
