Morphological changes in the Dry Creek (Sonoma County, California) associated with Warm Spring Dam, have reduced habitat availability for rearing fish, and potentially altered the community structure of benthic invertebrates that form the prey-base fo . . .

Wild Pacific salmon populations are declining throughout California. To strengthen applied salmonid restoration ecology, increased watershed-based understandings of socio-cultural issues thwarting recovery efforts are needed. This study explored perce . . .

I assessed introgression between sympatric Coastal Cutthroat Trout (Oncorhynchus clarki clarki, CCT) and steelhead (Oncorhynchus mykiss irideus, SH) from 7 sub-basins of the Smith River in northern California. Population, individual and genomic level . . .

Steelhead, Oncorhynchus mykiss, exhibit a wide variety of life histories, including a unique “half-pounder” life history, primarily found in Northern California and Southern Oregon. A half-pounder is an immature steelhead that returns to freshwater wi . . .

Hatchery fish have been implicated in the decline of stocks of naturally produced anadromous salmonids in the Pacific Northwest. I investigated the extent of predation by hatchery steelhead on naturally produced salmonid fry in the upper-Trinity River . . .

A total of sixty-nine wild juvenile steelhead were surgically implanted with acoustic transmitters and tracked within the estuary and main stem of the Russian River, California, for up to 141 days from mid-July to early December, 2005 and 2006. Each i . . .

I conducted an experiment to determine if resident rainbow trout (Oncorhynchus mykiss) isolated upstream of a barrier to anadromy in Freshwater Creek, California would exhibit migratory behavior after individuals were relocated to a downstream reach w . . .

Large woody debris is frequently placed into streams of the Pacific Northwest in an effort to improve habitat conditions for rearing juvenile salmonids. Unfortunately, many restoration projects do not incorporate monitoring of biotic response to these . . .

Polymorphic microsatellite markers were employed to explore fine-­scale genetic differences between adult summer steelhead trout and juvenile Oncorhynchus mykiss samples collected from the upper Middle Fork Eel River, California. Sampling locations we . . .

Fish passage improvement is used extensively throughout the Pacific Northwest to expand salmonid habitat to increase threatened salmon stocks. While culvert enhancement projects have been evaluated for physical responses, for example, the ability to w . . .

Redd counts – total number of distinct redds observed during a spawning season - are often used as an indicator of the abundance of salmonids spawning in streams and have recently been adopted for statewide assessment of status and trends in abundance . . .
