Genetic and meristic relationships of coastal cutthroat trout (Oncorhynchus clarki clarki) residing above and below barriers in two coastal basinsGriswold, Kitty E. 01 April 1996 (has links)
An investigation of the genetic and meristic patterns of coastal cutthroat trout
(Oncorhynchus clarki clarki) in two coastal basins, one in Oregon and one in Alaska,
revealed varying degrees of differences among populations within each site. Coastal
cutthroat trout collected from seven sites above and below barriers from Elk River,
Oregon were characterized by significant genetic structuring (Fst=0.095) based on
allozymes and significant differences among nine meristic characters. This may reflect
the geologic history and local conditions of the Elk River Basin. Despite this divergence,
Elk River populations were relatively similar to each other (Nei's genetic identity>
0.0987), suggesting that these populations share common ancestry. Fewer differences
were detected among the coastal cutthroat trout from four sites below and above a barrier
within Vixen Inlet, Alaska. Genetic structuring among populations was low (Fst=0.016)
and significant differences were detected in only two of nine meristic characters. This
may reflect the recent glacial history of southeast Alaska. In both sites, there was
concordance between allozyme data and meristic data. / Graduation date: 1996

Winter Habitat Selection Of Cutthroat Trout (Oncorhynchus clarki) In A Large Regulated RiverEnglund, Ronald A. 01 May 1991 (has links)
Microhabitat use by cutthroat trout and macrohabitat use by both cutthroat and rainbow trout were studied i n the Green River below Flaming Gorge Dam during the winters of 1988 and 1989. Microhabitat parameters used by cutthroat trout, such as focal velocity, depth, and fish elevation, differed significantly in eddies, runs, and riffles. Mean focal velocities in runs were 0.79 body lengths/seconds (bl/s), in riffles 0.66 bl/s, and in eddies 0.24 bl/s. Cutthroat trout size also varied significantly with macrohabitat; larger fish were found in riffles.
Macrohabitat use by cutthroat trout and rainbow trout differed significantly among species, macrohabitat types, and months. Both rainbow trout and cutthroat trout macrohabitat use shifted from lower velocity habitats during winter to faster velocity habitats in summer. Cutthroat trout and rainbow trout used macrohabitats at seasonally differing rates. Riffles were never selected in proportion to their abundance, especially during high winter discharges. Cutthroat trout implanted with radiotransmitters exhibited little movement during diel monitoring and did not change their occupation of macrohabitats.

Population structure of coastal cutthroat trout (Oncorhynchus clarki clarki) in the Muck Creek Basin, WashingtonZimmerman, Christian E. 23 October 1995 (has links)
The relationship of coastal cutthroat trout (Oncorhynchus clarki clarki) populations
in the Muck Creek basin, a 238 km�� southern Puget Sound stream basin in western
Washington, was examined using starch gel electrophoresis and meristic analysis. Coastal
cutthroat trout were collected from six sites throughout the basin including tributaries,
portions of the mainstem, and a lake. Four sites contained only resident trout, the lower
mainstem contained resident and anadromous trout, and the lake contained only mature
anadromous trout based on size and appearance. Patterns of allelic and meristic variation
suggest a significant structuring and separation of coastal cutthroat trout populations in the
basin. The lake population was distinguished from the other populations by significant
differences in allele frequencies and meristic characters. The other sites grouped more
closely together with significant variation among and between sites meristically and at
several loci. / Graduation date: 1996
