[1] In 1927, the U.S. Bureau of Fisheries hired Cable to assist Samuel Frederick Hildebrand at its research station and lab in Beaufort, North Carolina.
[1] In her lab in 1929–1930, Cable successfully cultured several fish through their larval stages, a ground-breaking accomplishment: prior to this time, for many species, their early life cycles were only known from capture of wild specimens.
With Robert A. Nesbitt, in 1943 she presented her research to Select Committee on Conservation of Wildlife Resources of the House of Representatives.
[1] Along with fellow Fish and Wildlife Service scientist Lucille Farrier Stickel, Cable was praised by Secretary of the Interior Harold L. Ickes in a press release, as well as in an October 1945 article on the wire services, "Women Scientists Helped Yanks Win the War.
