After the cutthroat program began, local angling groups successfully convinced the Departments of Fish and Game and State Parks to discontinue stocking, believing that spawning and juvenile rearing in the tributary streams was adequate to provide recruits to the fishery. Regardless of the source, long-term databases for this species are few, making stock status and trend analyses difficult. Anecdotal reports suggest that runs may have been significantly higher prior to this period. But with time the interest of sports anglers and biologists waned in favor of the glamour species, salmon and steelhead. Doug Jones and Cheryl Seifert, Alaska Department of Fish and Game, 4:15 – 4:40 Estuarine and saltwater residence of sea-run cutthroat trout National Marine Fisheries Service (NMFS) has proposed listing Umpqua River cutthroat trout as “endangered” under the Endangered Species Act (ESA). Thomas G. Northcote (10193 Giant’s Head Rd, RR # 2, Summerland B.C., V0H 1Z0, 604/494-8463). Where are we coming from? Restoration of a channelized salmonid stream, Oullette Creek, BC. Although the residence of coastal cutthroat trout in the ocean and estuaries is brief compared to other anadromous salmonids, it may be an important phase in their life history. Campton and Utter (1985) documented a significant number of cutthroat/steelhead hybrids in two Washington streams. Gordon H. Reeves (U.S. Forest Service, Forestry Sciences Laboratory, 3200 SW Jefferson Way, Corvallis, Oregon 97331). Lessons learned are described and recommendations offered for development of a volunteer network to share successful techniques for SRC management, regulation, and data collection. protection of existing stocks, and multi-year population and habitat studies. Chair, Rick Applegate, Trout Unlimited, 11:10 -11:35 Where are we coming from? Kitty Griswold, Oregon State University, 4:10 – 4:30 Population structure of coastal cutthroat trout in the Muck Creek basin, Washington John Palmisano, John Palmisano Biological Consultants, Beaverton, OR, 1:50 – 2:15 Umpqua sea-run cutthroat trout recovery plan: Management activities within the shadow of obscurity Interannual variation in coastal upwelling, sea temperatures, and El Niño events will be related to the meager data on estimates of cutthroat run sizes and abundance. Recent sampling found few salmonids and angling is poor. Phil Schneider, Oregon Department of Fish and Wildlife (retired), 11:35 – 12:00 The role of land management: past, present, and future The primary goal of the restoration was to restore the natural pool and riffle ratio with instream rock weirs built to duplicate natural riffles and pools. photo), Steelhead
Biological data on the status of nonanadromous cutthroat trout within the Umpqua River were very sparse. Population structure and differences among The planning committee was assembled in December 1994 and in July 1995, the symposium was formally accepted by the Oregon Department of Fish and Wildlife as an educational component of the STEP project on Winchester Creek. A stock assessment process has recently been initiated for coastal cutthroat in Washington. Estuarine and saltwater residence of sea-run cutthroat trout. We are all indebted to them. The coastal cutthroat trout (Oncorhynchus clarkii clarkii), also known as the sea-run cutthroat trout, blue-back trout or harvest trout, is one of the several subspecies of cutthroat trout found in Western North America. John F. Palmisano (John Palmisano Biological Consultants, 1990 NW 156th Avenue, Beaverton, OR 97006; 503/645-5676). In addition, the species also may live for periods in nearshore marine waters, in estuaries, in sloughs and associated backwaters, as well as standing waters ranging from very small bogs and ponds to large deep inland lakes. Dave Liscia, STEP Biologist with the Oregon Department of Fish and Wildlife, and Lyssa Burton, Fisheries Biologist with the Oregon Dunes National Recreation Area, have been important members of the symposium planning committee. There is very little information on the current distribution and abundance of sea-run cutthroat, or on population trends. Annual counts of fish over Winchester Dam on the North Umpqua River provide the best long-term source of information that we have for any sea-run cutthroat trout population in Oregon. The role of special angling regulations in maintaining and rebuilding populations of sea-run cutthroat trout. During Olive Spider Sea Run Cutthroat Recipe. 5 School of Resource Management, Simon Fraser University, Burnaby, BC. We are evaluating our database, using 25 citations to refine key words, abstracts, and citation format. In 1987 HSU Fisheries staff developed a coastal cutthroat broodstock to convert from steelhead to coastal cutthroat stocking. The sea-run cutthroat trout is the anadromous form of this subspecies. Status of sea-run cutthroat trout in California. They spawn in small tributaries from late winter to late spring depending on the locality. This stream, which once supported thriving populations of anadromous salmonids, was relocated and channelized in 1978, resulting in major changes in stream geometry affecting fish habitat. Wild populations have remained low and have exceeded a total count of 100 fish only twice since 1980. This suggests that estuarine and ocean conditions could be largely responsible for declines in sea-run populations. Many streams in the North and South Umpqua basins have high pH and large daily pH cycles. Written by Steve Johnson. William Pearcy, Oregon State University, 4:40 – 5:15 General questions and discussion, 5:15 – 7:00 Poster Session/Social Hour – High School Cafeteria, Session 2: Status of the Stocks–A Coastwide Review Chapter 4, Resident coastal cutthroat trout? Nevertheless, there are some surprising gaps in the coastal distribution of the species, such as that on northwestern parts of the Queen Charlotte Islands in British Columbia. Ron Ptolemy, British Columbia Ministry of the Environment, 1:25 – 1:50 Habitat enhancement: the view from Oregon To help avoid incomplete and ineffective restoration work, stream habitat surveys and project planning should be integrated with broader evaluations of aquatic ecosystem health such as biomonitoring and water quality monitoring. We offer a possible explanation: changes in the features of pools, such as depth and habitat complexity, may reduce suitability of the habitat. Patrick C. Trotter (Fishery Science Consultant, 4926 26th Ave. S., Seattle, WA 98108; 206/723-8620). This suggests that there is little gene flow between China Creek populations and other Elk River populations.
