The Idaho Department of Fish and Game stocks an eye-popping total of more than 30-million hatchery fish into Idaho waters each year. Stocking by the Department has been ongoing in one form or another for over a century. The number of species and strains can vary from year to year, but generally, stocking is primarily made up of 16 different species of trout and salmon. The Department uses all kinds of transportation to get fish to their final destination – including bikes, planes, and llamas.
Typically, fish are stocked from hatchery vehicles ranging in size from pick-up trucks outfitted with small fish tanks all the way up to semi-trucks capable of transporting millions of fish at a time. Staff take into consideration road and trail access, trail use restrictions, past stocking records, the species, size, and number of fish planning to be stocked, time of year, weather conditions, personnel availability, and cost before deciding how and when to stock fish in each location. At locations where staff are unable to access the waterbody with a hatchery truck, we have a variety of alternative fish-stocking methods available.
Since the 1940s, the Department has utilized fixed-wing aircraft to stock alpine lakes. As the pilot flies over the lake, a passenger in the plane releases fish with water out of the bottom of the plane. For remote lakes that are surrounded by challenging terrain including mountain ranges and trees, helicopters can be used. These helicopters are equipped with a specialized bucket that hangs below the helicopter from a cable, enabling the pilot to open and close the bottom of the bucket. This set-up allows the pilot to lower the bucket into the lake to collect water, fly to a landing site where staff can load the bucket with fish, and then return to the lake to release the fish by opening the bucket just above the water’s surface.
In certain situations, ATVs, bikes, backpacks, or even pack animals are used. Read more
