Long range transportation of catchable fish with these new units is now possible. The stocking of remotely located lakes in the high mountainous areas of California has for many years presented a difficult task, since this was always done by man and pack animal. Early in 1947 the Bureau experimented with planting fish by airplane. Experiments were continued during Figure 1 (i. lioading- trout for stocking. The pickup truck is equipped with a recently developed 150-gallon aerated planting tank. I'Jtotograph by Kramer Adams. The use of a C-45 Beechcraft plane in aerial trout planting was started in 1949 and greatly expanded in 1950. The plane is e(iuipped with a tank with a trii) valve seated in the aerial camera port. Fish are trans- ported in 12 light aluminum cans and the plants for each lake, of which three to five may be covered in a single trip, are loaded into the larger tank successively. Tlic crew consists of two pilots and a planter in the cabin. All checks so far made both from the air and on the ground indicate almost c()in|)Iete success. Two barren lakes ])lanted in 1949 were checked in 19r)() jind very good survival was aiii)ar('nt. In 1950 a total of 426 lakes from Siskiyou to Inyo County was phmted with 1,6;5;5,275 trout. The cost for the use of the plane was $2,—less than was sometimes paid to one packer in previ(ms years. Tables showing the total numbers of fish I'eai'cd and ])lanted in each county and obtained thi'ongh i-escue work will be found in Ai)pendix D. It has been found necessary to change the period of accounting for hatchery production from the calendar year to the fiscal year in order. Please note that these images are e
