Great Lakes Commercial Fishing Catch 1929-2014

Since 1971 the Great Lakes Science Center (GLSC), formerly known as the National Fishery Center-Great Lakes (National Biological Service), the Great Lakes Fishery Laboratory (U.S. Fish and Wildlife Service)(FWS/GLFL), and the Ann Arbor Biological Laboratory (Bureau of Commercial Fisheries), have acted as repositories for the processing, reporting, and storage of U.S. Great Lakes commercial fishery statistics. The GLSC prepares annual summaries of these data for use by federal and state resource managers and other interested public and private organizations. The data collection system was organized in 1926 by Dr. John Van Oosten of the Bureau of Fisheries and was first put to use by the State of Michigan in 1927. Commercial fishermen licensed by that state were required to submit daily fishing reports indicating gear used and amount of catch. In succeeding years the system was improved and expanded until by 1950 all the Great Lakes states and the Province of Ontario, Canada, had similar systems.自1971年起，大湖科学中心（Great Lakes Science Center, GLSC）——其前身为国家渔业中心-五大湖分部（National Biological Service）、美国鱼类及野生动物管理局下属大湖渔业实验室（U.S. Fish and Wildlife Service，简称FWS/GLFL）以及安阿伯生物实验室（商业渔业局）——一直承担美国五大湖商业渔业统计数据的处理、报告与存储工作。该中心会编制上述数据的年度汇总报告，供联邦与州级资源管理者及其他相关公共、私营机构使用。这套数据收集体系由渔业局的约翰·范·奥斯坦博士于1926年搭建，并于1927年由密歇根州首次投入使用。该州持照商业渔民需提交每日捕捞报告，列明所用渔具及捕捞总量。后续年份中，该体系不断优化扩容，至1950年，所有五大湖沿岸州及加拿大安大略省均已建立类似的数据收集体系。
