Throughout its native range, the Yellowstone cutthroat trout (YCT), Oncorhynchus clarkii bouvieri, is declining dramatically in both abundance and distribution as a result of introgression with introduced rainbow trout (RBT), O. mykiss. We sampled over 1,200 trout from the South Fork of the Snake River (SFSR) watershed, in southeastern Idaho and western Wyoming, and measured the extent of introgression of RBT genes into native gene pools of YCT using seven species-specific, co-dominant nuclear genetic markers. We also used mitochondrial DNA (mtDNA) haplotype differences between the two parental trout species to determine the directionality of the hybridization. We found low levels of RBT introgression (only 7% of sampled individuals had one or more RBT alleles) into YCT gene pools, with the majority of hybrids (78%) occurring in mainstem localities of the SFSR and in lower elevation reaches of certain tributaries. Hybridization was bidirectional with respect to mtDNA haplotype, but the majority of hybrids (75%) had YCT maternal haplotypes, indicative of the greater proportion (90%) of YCT-genotypes in the SFSR watershed. The primary factor influencing the geographic distribution of RBT introgressed individuals was fluvial distance from localities of stocking origin. To a lesser extent, elevation, also influenced the distribution of hybrid genotypes, with several entire tributaries and all upper elevation reaches within tributaries harboring only YCT-genotypes. Important management implications of the study suggest targeting particular tributaries and upper reaches within tributaries for YCT protection and exclusion of RBT hybrid colonization.

“…Spawning migration has been the subject of extensive studies in a large number of anadromous salmonids (for reviews see Doving 1989;Harden Jones 1968;Hasler 1966;Leggett 1977;Quinn 1990;Scheer 1939;Stabell 1984). Migration of potamodromous salmonid species within freshwater systems has received less attention.…”

“…Previous reviews in the field of homing (Scheer, 1939;Hara, 1970;Hasler, Scholz & Horral, 1978;Cooper & Hirsch, 1982) and migration (Harden Jones, 1968;Banks, 1969;Leggett, 1977) give useful surveys of the existing literature. All these reviews, however, adhere to established theorems in the field which should not necessarily be accepted as such.…”

CONTENTS 0. B. STABELL reliable data are usually those from the river of release. Tags, on the other hand, give advantages both with respect to data on straying rate and high-sea fishing. Straying rate (SR) here means the ratio:where RR are the number of fishes recovered in streams other than the one of release, and TR represents the total number of fishes recovered in streams. (It should be noted that straying rate equals the percentage of fish recovered in streams other than the one of release from the total stream catch. The expression percentage is, however, omitted to avoid confusion with percentages of recovery from those released.) Table I presents data, found in the literature, from 'homing' experiments on native, wild Atlantic salmon. As can be seen, the recovery of fishes in their native stream varies between I yo and 3.4 Yo of those released, the only clear exception being experiment no. 7.Very little straying is registrated in the above experiments, the exception again being experiment no. 7. Concerning the straying rate stated in experiment no. 14, Table I , it should be noted that the cases registered were all within the native watershed. A maximum straying rate of three appears to occur in Canadian and Norwegian rivers. This figure also agrees with data from rivers on the west coast of Sweden where straying rate is less than one (Carlin, 1969a), and with data from Britain and Ireland where straying rate averages 2.7 and 3.0, respectively (Thorpe & Mitchell, 1981). Data on Baltic salmon (S. salar L.) show a straying rate of approximately two (Carlin, BODZNICK, D. (1975).
