Table 7 -- Characteristics of greenback cutthroat trout spawned in hatcheries as part of recovery efforts, including hatchery used, year spawned, source, year class name, number, and sex of fish used, and eggs and fry produced. Source denotes the origin of fish being spawned. If the hatchery received fish or eggs from a wild population to support a broodstock, the year of arrival in the hatchery and the water providing the fish are noted. If fish were derived from spawning in a hatchery, the year of spawning and hatchery are noted. To the extent possible, only numbers of fish successfully producing viable offspring are included. If the sexes of fish of different sources were known, it is indicated in parentheses (F, female; M, male) or overall in the following column. Abbreviations are: BFRH, Bellvue Fish Research Hatchery; BFTC, Bozeman Fish Technology Center; and SNFH, Saratoga National Fish Hatchery. Missing data are denoted by a dashed line.
