Dropping fish out of a plane might seem like a bizarre thing to do, but it happens several times a year in Utah. Many of the state's high-altitude lakes are not accessible by truck, but still make good fishing locations for anglers who are willing to make the trek. The solution? Dropping a fish bomb to replenish stock. 

To make the aquatic air-drop happen, planes are fitted with special compartments that fill with water to hold the fish. Aerial stocking pilots collect the fish from various hatcheries at airports across the state. 

While some of the fish die during the 45 metre (150 foot) fall, a report from the Utah Division of Wildlife Resources found the plane ride stresses fish less than a ground vehicle ... meaning overall, more fish make it to the lake alive.
