The U.S. Bureau of Fisheries was established in 1871 as a federal agency responsible for the management and conservation of fishery resources in the United States. Its primary goal was to promote sustainable fishing practices and protect aquatic ecosystems. The Bureau conducted research, developed fish hatcheries, and implemented regulations to ensure the health of fish populations. In 1940, the Bureau of Fisheries merged with the U.S. Bureau of Biological Survey to form the U.S. Fish and Wildlife Service. This new agency expanded its focus to include wildlife conservation and habitat protection, continuing the legacy of the Bureau in safeguarding the nation's natural resources.
