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
