 From 1881 to 1903, the Commission also published an annual "Bulletin of the United States Fish Commission" summarizing the commission's "Annual Report to Congress" and correspondence; the bulletins included detailed catch reports from fishermen and commercial fishing port agents around the United States and Canada, reports and letters from naturalists and fish researchers around the United States and in other countries, and descriptions of the Commission's exploratory cruises and fish hatchery efforts.Beginning in 1884, the Commission published the seminal work "The Fisheries and Fisheries Industries of the United States".After the United States purchased Russian America from the Russian Empire in 1867 and created the Territory of Alaska, enforcement of whatever regulations to protect fisheries and marine mammals that existed in Alaska fell to the revenue cutters of the United States Revenue-Marine, which in 1894 became the United States Revenue Cutter Service and was one of the ancestor organizations of the United States Coast Guard.
