Check out this video of an aerial fish-drop. According to LiveScience, Utah Wildlife officials have been restocking more than 200 remote lakes this way since 1956.
This might look a little rough, but Utah Division of Wildlife Resources explained in a tweet (see below) that more than 95% of the tiny fish survive the fall.
Fun fact: We stock many of Utah's high-mountain lakes from the air. The fish are tiny — anywhere from 1–3 inches long — which allows more than 95% of them to survive the fall. #Utah #TroutTuesday pic.twitter.com/kotDe91Zzw— Utah DWR (@UtahDWR) August 21, 2018
