<br />Ja ffe specifi ca 11 y used the common name yell owfi n trout (1 a truite a <br />nageoires jaunes) and the scientific name of Salmo mykiss macdonaldi for the <br />trout he raised from eggs sent by the U.S. Fish Commission. He also stated <br />that the eggs were taken from "La Mesa, Colorado," which is verified by the <br />U.S. Fish Commission Reports for 1899 and 1902 that 10,000 and 20,000 eggs of <br />"black-spotted" trout from the Grand Mesa lakes were shipped to Jaffe. There <br />is no basis in the Fish Commission reports or in Jaffe's paper for the desig- <br />nation of the source of these eggs as macdonaldi. We can surmise that some- <br />one at the Leadville hatchery designated the shipments to Jaffe as yellowfin <br />trout under the prevalent notion that one or more of the lakes from which eggs <br />were taken had "yellowfin trout." It is not uncommon for cutthroat trout, in <br />general, to have yellow fins. We suggest that the European shipments of <br />"yellowfin" trout were actually based on S. c. pleuriticus from the Grand <br />Mesa. <br />Persico (1903) recounted the joyful news to Italian fish culturists of <br />Jaffe's importation of the new American trout, the "trota dalle pinne gialle." <br />Besides the shipments to Jaffe, 10,000 "blackspotted" trout eggs were sent to <br />Belgium in 1902 and 25,000 to Wales in 1904. <br />Inquiries with the fish culture division of FAO of the United Nations <br />failed to turn up information on the fate of the early European importations <br />of cutthroat trout. FAO Fisheries Technical Paper 213, "Register of inter- <br />national transfers of inland fish species," lists only three introductions of <br />cutthroat trout into Europe; Denmark in 1962, Sweden in the 1960's, and <br />Cyprus in 1980. <br />The enigma of the yellowfin trout remains, only the uncertainties <br />surrounding this fish have been expanded. <br /> <br />,. <br /> <br />IL/ <br />
