Published information on the anadromous coastal cutthroat trout, Oncorhynchus clarki clarki, can be found in many technical journals and in published and unpublished management reports. All fish must be caught legally in open waters in Oregon on fly fishing tackle and carefully released. There is the continued threat of repeating expensive failures and endangering fish populations. Chair: Jack Williams, Bureau of Land Management, 8:30 – 8:55 Status and trends of anadromous salmonids in the coastal zone Panelists will have 5 minutes each to address the following questions: 1) What is the value (social, economic, other) of sea-run cutthroat to your group? Unfortunately, reliable time series of sea-run cutthroat abundance are not available for rigorous comparisons with environmental factors. A total of 612 anadromous cutthroat stocks was identified. Box 240020, Douglas, AK 99824; 907/465-4311) and Robert E. Gresswell (U.S. Forest Service, Forestry Sciences Lab, 3200 SW Jefferson Way, Corvallis, OR 97331). Coastal cutthroat trout abundance is low in most waters, particularly where juvenile Sea-run cutthroat trout. Size limits in conjunction with a reduced creel have been successful in diminishing the effects of angler harvest provided that 1) size structure of the population, both current and historical, and size distribution of angler-captured fish are monitored closely, and 2) mortality associated with hooking and handling is minimal. Smith River - Coastal California Fly Fishing Guides. It appears that numbers remain depressed for extended periods following such disturbances, for reasons that are not clear. Sea-run cutthroat adults show a preference for small streams, low gradient systems, and the lower gradient downstream reaches of large river systems, although in some populations adults migrate considerable distances upstream. Patterns of allelic and meristic variation suggest a significant structuring and separation of populations of coastal cutthroat trout in the basin. Harvest restrictions for anadromous cutthroat trout are often incorporated in more general “trout regulations”, but stipulations that are specific to this group have been implemented in some areas. To be considered an ESU, a population must 1) be reproductively isolated from other populations, and 2) contribute to ecological/genetic diversity of the biological species. 95521; 707/826-3445). Plunge pools are also a favored habitat type during summer, as the fish hide behind the obstruction that causes the plunge. Volunteers started numerous local and regional cooperative projects in Washington State, emphasizing Potential causative factors include: a significant decline of near-ocean productivity since the mid-1970’s, genetic and fishery consequences of widespread use of hatchery sea-run cutthroat trout throughout Oregon coastal and lower Columbia River streams, and reduction of stream and estuary habitat complexity. Volunteer angling groups have recognized the long-term decline of sea-run cutthroat trout (SRC) stocks, and are acting to reverse this trend. Tom Northcote, University of British Columbia, 3:50 – 4:15 Migratory patterns of mature cutthroat trout from They are the ones that got be into sea run fishing. Studies on other subspecies of cutthroat trout suggest a positive response to catch-and-release-only (no harvest) and various size regulations (with no bait); however, depressed populations generally do not respond to reduced creel limits alone. Fly-fishing for sea-run cutthroat trout on the Alsea River, 8-31-18. This paper summarises the cutthroat trout component of a review of anadromous salmonid stock status in British Columbia and Yukon streams that was performed for the North Pacific International Chapter of the American Fisheries Society. by now) to serve on the planning committee, to make key contacts in the fisheries community, and to compile the data for the current status review of sea-run stocks in Oregon. The results of a two-stage questionnaire completed by fisheries staff were examined for patterns and correlates to success rate. Cutthroat trout present in Lake Eva during July were defined as resident, and a two-event mark-recapture method was used to estimate that 1,900±232 resident fish were present and had an average fork length of 236 mm. Three varieties of Cutthroat trout are available to Washington and Oregon anglers. We are producing an annotated bibliography on disk files and maintaining a computer and hard copy literature library. Evolution, systematics, and structure of Oncorhynchus clarki clarki. It is important to examine all of these factors in the context of dynamic and variable environments that characterize the coastal zones. Anglers will primarily try for spring and fall chinook salmon, and standardized hook-and-line sampling habitat.
