Its mandate is to protect stocks of the five species of Pacific salmon. Its precursor was the International Pacific Salmon Fisheries Commission, which operated from 1937 to 1985. The PSC enforces the Pacific Salmon Treaty, ratified by Canada and the U.S. in 1985. ==Origins== The first commercial salmon fisheries in the Pacific Northwest were started in the early 1800s. Lucrative fisheries were established on the Columbia and Fraser rivers, including canneries geared for export. Harvests increased year-to-year until the 1910s. The abundance of the resource had precluded any disagreements between the Canadian and American governments until this point. However, from the 1920s onward, stocks began to decline, a result of over-fishing and the degradation and obstruction of migratory rivers. Competition between American and Canadian fisheries for the dwindling resource led to conflict. Disputes were complicated by the fact that the salmon crossed several international borders during their lifespan. In 1930, the governments met and proposed the Fraser River Convention to regulate fishing and mitigate environmental damage to salmon habitats. The International Pacific Salmon Fisheries Commission was formally founded in 1937. 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「Pacific Salmon Commission」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.
