  Citation × Citation Citation Abstract Copy Title: The size of the Oregon coastal salmon runs in the mid-1800s Author: Meengs, Chad C. Abstract.- Increasing the abundance of salmon in coastal Oregon rivers and streams is a high priority public policy objective. Salmon runs have been reduced from pre-development conditions (typically defined as the 1 850s), but it is unclear by how much. Considerable resources have been allocated to restoring salmon runs, but it is uncertain what the current recovery potential is because much of the freshwater and estuarine habitat for salmon has been altered. The goals of all recovery efforts are based on assumptions, often unstated, for what the size if the runs were prior to significant habitat alteration, coupled with an estimate of the amount and quality of freshwater and estuarine habitat currently available. At one extreme, it may be that current run sizes reflect the recovery potential of the existing salmon habitat. At the other extreme, the recovery potential may be as high as the mid 1800 levels. Historical salmon runs sizes on the Oregon coast were estimated using two methods: (1) Converting aboriginal population levels and their salmon consumption rate into numbers of salmon; (2) Extrapolating cannery pack into numbers of salmon. Annual aboriginal harvest of all salmon species is estimated to have been approximately 10 million pounds/year or between 1.75 million and 5.36 million salmonids, a harvest level similar to that occurring during the height of commercial fishing on Oregon's coastal rivers in the late 1 800s and early 1 900s. Extrapolating cannery pack data, the estimated size of the late 1 800s aggregate runs of coho (Oncorhynchus kisutch) was 1.5-2.5 million. The estimated size of aggregate runs of chinook (Oncorhynchus tshawytscha) runs was 290,000-517,000. Compared to mid 1 800s coho estimates, current runs (during favorable ocean conditions), are 11-19%. During poor ocean conditions, current coho runs are 3-6% of the historical size.

  Citation × Citation Citation Abstract Copy Title: The future of the Columbia River salmon fisheries Author: Oregon. Fish Commission, Rich, Willis H. (Willis Horton), 1885-1972 The salmon runs of the Columbia River constitute one of the most important natural resources of the states of Oregon and Washington. Thousands of people are dependent, wholly or in part, upon these resources for their livelihood; and their welfare is dependent upon the maintenance of the salmon runs. It is to the special interest of these people that the salmon supply be maintained at the level of maximum productivity and, indirectly, it is to the interest of all the citizens of these states that this be done. In recent years it has become increasingly evident that these resources, taken as. a whole, are decreasing in productivity and it has been frequently pointed out that this decrease is due primarily to the operation of two factors-- a very intensive fishery and a reduction in spawning and rearing areas due to the utilization of the water resources of the Columbia basin for other purposes. These influences, however, have affected the several species of salmon that are found in the Columbia River quite differently; the more valuable species, Chinooks and bluebacks, showing more evidence of depletion than do the other species, silver salmon, chums and steelhead.

  Citation × Citation Citation Abstract Copy Title: Policy Conundrum: Restoring Wild Salmon to the Pacific Northwest Author: Lackey, Robert T. Year: 2001 Restoring wild salmon runs to the Pacific Northwest is technically challenging, politically nasty, and socially divisive. Pa st restoration efforts have been largely unsuccessful. Society’s failure to reverse the continuing decline of wild salmon has the characteristics of a policy conundrum: nearly everyone supports, abstractly at least, restoring salmon runs; considerable public and private resources have been devoted to their restoration; but society collectively remains evidently unwilling to make the painful decisions clearly necessary to arrest their decline. The salmon policy conundrum is characterized by competing societal priorities being adjudicated in a political environment where few are willing to acknowledge publicly the future consequences of prior de facto policy choices. Decisions already made have greatly circumscribed the status of wild salmon in the Pacific Northwest through at least the next several decades. Barring a near wholesale reversal of many of society’s previous decisions (and apparent priorities), and allowing for considerable year-to-year and decade-to-decade variation in run size due in part to oscillations in climate and oceanic conditions, I conclude that through the twenty-first century, many, perhaps most, stocks of wild salmon in the Pacific Northwest likely will remain at their current low levels or continue to decline in spite of current protection and restoration efforts.

  Citation × Citation Citation Abstract Copy Title: Salmon fisheries of the coastal rivers of Oregon south of the Columbia Author: Gharrett, John T., Oregon. Fish Commission, Hodges, John I. In spite of the progressive restrictions of the commercial river fishery during the past fifty years, the trend of the salmon populations of the coastal rivers has been downward. It is almost impossible to isolate and analyze separately the causes of this decline, and any attempt to saddle one factor with the responsibility is an oversimplification of the facts. The salmon runs have too long been taken for granted. During the rapid development of the coastal area, the welfare of the fish was ignored. The physical character of the watersheds was changed as the timber was stripped off, and in these same operations streams were blocked by log jams, mill dams, splash dams and even the gravel from the spawning beds of the streams was removed to be used in road construction. At the same time other water uses were developed for power and irrigation. While the productive capacity of the streams was being reduced and the runs resultantly lowered, the fishermen competed with each other for the remaining fish and blamed one another for the lack of fish. Apparently, at no time until recent years was a serious program developed or even considered for the conservation of the salmon runs. To date with the possible exception of one or two instances pollution has not been a serious factor in the decline of the salmon runs. The commercial river fisheries are of considerable importance to the economy of various communities on the Oregon coast. They also provide a source of salmon to those who have no other access to this productive natural resource. The recreational salmon fishery is also an important source of income to Oregon coastal communities. It is, therefore, important to these communities and the State as a whole that the salmon runs be maintained at their maximum productive level. To accomplish this the Oregon Fish Commission has developed a long range management program for the coastal rivers. This encompasses stream clearance and improvement projects, the use of artificial propagation in introducing runs and supplementing natural runs, and the close regulation of the commercial river and offshore fisheries. This program has not been underway long enough to ascertain its success, but in several instances it appears to offer promise. However, close check is being kept on the runs in order that the results of this program can be evaluated as soon as possible. The stream surveys and other observations indicate that the coastal rivers and their salmon populations are not beyond redemption, and that under proper management can be made to yield annually several times their present production.

(Willis Horton), 1885-1972 Exceptional data are available for the study of the salmon runs of the Columbia River in 1938. Detailed figures on catch were supplied by Oregon and Washington in such form that they could readily be combined with the counts at Bonneville Dam to provide a basis for estimating the escapement. Tables show the catch of each species for each week in each of six zones, and the counts at Bonneville and Rock Island dams. The general course of the run of each species is shown. The numbers of fish bound for the spawning grounds above Rock Island Dam are estimated as follows: Chinook salmon entering Columbia River before May 1, 4 percent; during May, 6 percent; June and July, 15 percent; and August to December, 1 percent. Blueback salmon entering the river during the above periods, 40 percent. Steelhead trout entering the river during June to September, 1 percent; during the rest of the year, 10 percent. Fishing intensities are shown by escapement to catch ratios. Percentages of chinook salmon escapement are less than 15 during May; 17 during June and July; and 33 during the remainder of the year. The June and July runs are now greatly depleted, and an important part of these runs spawns above Rock Island Dam. The blueback salmon escapement is about 20 percent, and of steelhead trout about 33 percent. Weekly and seasonal closed periods are shown to be almost entirely ineffective for increasing the spawning escapement. Exploitation is further increased by the intensive troll fishery conducted from Monterey Bay to southeastern Alaska. Chinook salmon are also subjected to a sport fishery of considerable importance. Main runs of salmon to the Columbia River are practically unprotected and are fished with destructive intensity. Title: The salmon runs of the Columbia River in 1938 Author: Oregon.

  Citation × Citation Citation Abstract Copy Title: An investigation into the genetic basis of migration timing in Chinook salmon (Oncorhynchus tshawytscha) Author: O'Malley, Kathleen Gallen, 1976- The genetic basis of adaptation is complex as many fitness-related traits are quantitative and likely influenced by multiple genes with variable effects across different selective environments. One important adaptation for anadromous Chinook salmon (Oncorhynchus tshawytscha) is the time at which individuals return to natal breeding sites within a reproductive season. Here, I tested for adaptive genetic differentiation among temporally divergent migratory runs using candidate loci. First, I isolated and characterized two copies of the circadian rhythm gene, Clock, from Chinook salmon (OtsClock1a and OtsClock1b). Phylogenetic analysis revealed that these copies likely arose subsequent to the salmonid genome-wide duplication event. Each copy contains a polyglutamine repeat motif (PolyQ), an essential binding domain of this transcription factor. However, a 1200bp non-coding segment, showing >90% sequence identity to the Salmo salar Transferrin gene, is located downstream of the OtsClock1a PolyQ, yet absent from OtsClock1b providing evidence for nonhomologous recombination. Another candidate, Ots515NWFSC, shows sequence identity to three salmonid genes central to reproductive development: Gonadotropin-releasing hormone, CYP19b-I, and Ghrelin. I employed OtsClock1b and Ots515NWFSC to test for differentiation in two unique systems: Feather River, California; and Waitaki and Poulter Rivers, New Zealand. Based on length variation in these candidate genes, Feather River fall and spring run Chinook salmon are genetically differentiated. In contrast, these seasonal runs are genetically indistinguishable based on neutral microsatellite loci. Correspondingly, temporally divergent Chinook salmon runs in the Waitaki and Poulter Rivers show greater differentiation based on variation in OtsClock1b and Ots515NWFSC than microsatellite loci. Tests for selective neutrality indicate that OtsClock1b and Ots515NWFSC are likely under selection in both systems. In addition, I found evidence for a latitudinal cline in two OtsClock1b PolyQ alleles among 42 Chinook salmon runs which is likely maintained by selection and thus may reflect an adaptation to photoperiodic parameters. Lastly, a hierarchical gene diversity analysis of OtsClock1b PolyQ variation revealed that run timing explained 43.7% of the overall genetic variance which contrast sharply with the 8.1% calculated for microsatellite loci. Evidence presented here suggests that OtsClock1b and Ots515NWFSC may influence migration timing of Chinook salmon.

Tests for selective neutrality indicate that OtsClock1b and Ots515NWFSC are likely under selection in both systems. In addition, I found evidence for a latitudinal cline in two OtsClock1b PolyQ alleles among 42 Chinook salmon runs which is likely maintained by selection and thus may reflect an adaptation to photoperiodic parameters. Lastly, a hierarchical gene diversity analysis of OtsClock1b PolyQ variation revealed that run timing explained 43.7% of the overall genetic variance which contrast sharply with the 8.1% calculated for microsatellite loci. Evidence presented here suggests that OtsClock1b and Ots515NWFSC may influence migration timing of Chinook salmon. Close

  Citation × Citation Citation Abstract Copy Title: A Review of Fishery Research in the Pacific Area Author: Atkinson, Clinton E. Year: 2001 It is impossible to place a date on the beginning of fishery research. It no doubt existed in a primitive way among the earliest civilizations. For practical reasons, the scope of this paper is limited to the four countries bordering the North Pacific--Japan, Canada, Russia and the United States--and to research directed towards a better understanding and management of the fishery resources of commercial value. It is interesting that development of fishery research in three of the four countries was prompted by a serious decline in their salmon runs and by the adoption of hatcheries as a means to restore or maintain the depleted runs. The only difference was in Russia where fishery research began with a decline in sturgeon in the Volga and the Caspian Sea. In the Russian Far East, however, it again was a decline in salmon in the Amur and Sakhalin rivers and all were linked primarily to loss or damage to their freshwater environment. Overfishing and destructive fishing practices were recognized almost from the beginning but it was not until 1917 that the work of Thompson on Pacific halibut led to the development of modern theory of population dynamics for the management of the fisheries. Following are notes on the development of fishery research in each of the four countries. Title: A Review of Fishery Research in the Pacific Area Author: Atkinson, Clinton E.

  Citation × Citation Citation Abstract Copy Title: Addressing Fish Uncertainty: The Quest for Rational Decisionmaking Author: Koss, Patricia, Katz, Mike, Shawcross, Jennifer Year: 2001 This paper explores the policy efforts dealing with the problem of declining Pacific Northwest fish runs. Results have been disappointing. Decades of expensive efforts costing billion of dollars have been relatively ineffective in increasing salmon runs. Many species of wild fish continue to decline or remain significantly below target levels of recovery. The issue of scientific and economic uncertainties is examined. Past and current policies have failed to adequately account for these uncertainties. One overall recommendation of this paper is that policymakers and their advisors should explicitly identify any decision criteria upon which they base their judgments or conclusions. A second recommendation is that policy analysis should be explicit about uncertainties. We offer the eighteen decision rules for fashioning fish recovery decisions in an environment of uncertainty.
