in its waters. The USFWS continued to operate fisheries research ships and the Pribilof tender until the BCF's seagoing fleet was transferred to the National Marine Fisheries Service (NMFS), an element of NOAA, upon the creation of NOAA on October 3, 1970. Although the NMFS continued to operate the Pribilof tender until 1975, the rest of the ships were transferred from the NMFS to a unified NOAA fleet during 1972 and 1973. The modern NOAA fleet therefore traces its ancestry in part to the USFWS fleet operated by the BCF. Both before and after the FWS became the USFWS in 1956, ships of its fleet used the prefix while in commission. The BOF usually named its ships after aquatic birds, and ships the FWS inherited from the BOF in 1940 retained those names in FWS service. However, the FWS/USFWS thereafter usually named vessels it acquired after people who were notable in the history of fisheries and fisheries science.
