The buildings exhibit a consistency of style and construction, with exposed gable trusses and oversized paired logs at the corners, all with brown paint.〔Kaiser, Harvey (1997). "Landmarks in the Landscape", San Francisco: Chronicle Books ISBN 0-8118-1854-3, p. 147〕 The district is located on the shore of Yellowstone lake near the Lake Hotel The hatchery was established to provide Yellowstone cutthroat trout eggs for state and federal hatcheries outside of Yellowstone. ==History== By the early 20th century, a number of hatcheries were established in the park by the U.S. Bureau of Fisheries including hatcheries at Yellowstone Lake and Soda Butte Creek. The current Lake Fish Hatchery replaced an earlier hatchery at Lake. These hatcheries not only produced stocks for the park, but also took advantage of the great spawning stock of Yellowstone cutthroat trout to supply eggs to hatcheries around the U.S. Between 1901 and 1953, 818 million trout eggs were exported from the park to hatcheries throughout the U.S. The hatcheries and stocking operations had both positive and negative impacts on the quality of angling in Yellowstone National Park in the first half of the 20th century. Many native populations were displaced by non-natives, but there was quality brown and rainbow trout fishing in the Firehole, Madison and Gibbon rivers. Ultimately stocking and hatchery operations negatively impacted Yellowstone cutthroat, westslope cutthroat trout and Arctic grayling populations in the park. In 1953 the National Park Service began closing the hatcheries and stopping stocking operations. The last fish stocked for the benefit of anglers was in 1955 after some 310 million fish had been released in park waters since 1889. The last hatchery was closed in 1957. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lake Fish Hatchery Historic District」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
