Six major types of commercial gear have been used to take salmon and steelhead on the Columbia River; namely, gill nets, set nets, seines, traps, fish wheels and dip nets. 2. The five important commercial species in the Columbia River are chinook, silver, blueback and chum salmon and steelhead trout. 3. In 1927 fish wheels were eliminated in Oregon. In 1935 fish wheels, traps, seines and set nets were eliminated in Washington. 4. The effect of the gear change in Washington in 1935 has been to increase the take in other gears, while the previous trend of total landings has not changed appreciably. 5. There is no conclusive evidence that the elimination of fixed gear in Washington increased the escapement of salmon and steelhead. 6. There is no conclusive evidence that any gear is injurious to the run except by subtracting fish from the run. 7. Measures designed to increase the escapement should apply to all gears and cover the entire life history of each species.

  Citation × Citation Citation Abstract Copy Title: The 1951 Alsea River silver salmon tagging program Author: Oregon. Fish Commission, Cleaver, Fred C. (Frederick Charles), 1916-, Morgan, Alfred R. During a tagging operation conducted in 1951 on the Alsea River, 1,142 adult silver salmon were tagged with plastic Petersen-type tags and stainless steel jaw tags. An attempt was made to determine whether tagged fish released in different apparent conditions suffered differential mortalities. Under the hypothesis that the recovery of the fish in the commercial fishery was independent of the apparent condition of the fish when it was released, a significant value of chi-square was obtained. However, it was concluded that this significance was a result of sampling differences and not actually due to differences in mortality. The number of fish taken in the commercial catch each week was calculated by dividing the number of pounds in the weekly catch by the average weight of the fish in the samples for that week. It was calculated that the commercial fishery took approximately 14,000 fish during the season, which was only about 15 per cent of the run available to the fishery. This is an extremely low fishing mortality and is considerably lower than had been expected. The number of tags taken each week by the commercial fishery was calculated by dividing the number of fish in the catch each week by the number of fish per tag in the samples for the week. It was calculated that 67 tags were taken during the season by the commercial fishery. This number of recoveries was 15.5 per cent of the 438 tags available to the fishery. With the cooperation of a number of boat moorages on the Alsea River, an estimate of the sport catch of silver salmon was made. It was calculated that the lower river sport fishery took approximately 3,000 adult silvers with an additional 500 fish being taken by the bank fishery. The weight of the total catch of 3,500 fish was calculated to be about 33,000 pounds. This weight formed 20.2 percent of the combined commercial and sport catches. It was calculated that 18 tagged fish were taken in the sport catch. A total of 44 numbered Petersen and jaw tags were recovered from both dead and live fish which had reached spawning areas. This number includes three tags recovered from the spawning grounds of adjacent streams. When the tagged fish were examined according to areas recovered, it was found that Drift Creek had a smaller number of fish per tag than any other area with one exception. Recoveries appeared to be distributed throughout the drainage from any particular time of tagging. Fish enter the lower river together, then separate to the various spawning areas in the system. Several fish moved from the tagging location in the Alsea River to adjacent streams. About 7 percent of the total recoveries in Table 12 were made from streams other than the Alsea River. The Petersen and jaw tag recoveries in the samples of the commercial catch were examined for selection of the Petersen tags by the nets. The percentage by size group in the catch of fish with each type of tag was about the same as the percentage by size group with each type of tag at the time of release. Large losses of tags in the fishery would have been reflected by a higher number of fish per tag on the spawning grounds. Since the gill-nets did not appear to be selective on either type of tag, the Petersen tags, jaw tags, and tag scars were combined in the calculations involving tag recoveries. After the fish moved beyond the fishing area, many still did not move rapidly to the spawning grounds. Several were taken in tidewater or in the vicinity of tidewater 48-58 days after they had been tagged. The average time between tagging and recovery on the spawning grounds was 63 days for live fish and 70 days for dead fish. Using the method proposed by Schaefer (1951a) for obtaining a population estimate from spawning ground recoveries, an estimate of the population available to the fishery was made from the number of tags recovered by sampling the commercial catch. It was calculated that approximately 90,000 fish were available to the fishery. About 89,000 fish were calculated to be available to the fishery when the equation N = nt/s was used, where N = the population, n = the sample size, t = the number of fish tagged, and s = the number of tag recoveries. The 95 percent limits of confidence for the population estimate derived from the equation N = nt/s were calculated using the method developed by Chapman (1948). The lower limit was found to be 63,736 fish, and the upper limit was 119,371 fish. Approximately 63,000 of the fish available to the commercial fishery continued the migration to the spawning grounds. Spawning ground tag recoveries provided an estimate of the population in the lower river which was in close agreement with the estimate of the population made from tag recoveries in the commercial fishery.

The Commission had been studying the matter for a little more than a year in Tillamook, Yaquina and Coos bays and in this document gives its first recommendations, primarily focusing on the gaper, or “horse,” clam fishery.

Fish Commission, Morgan, Alfred R., Gerlach, Arthur R. 1. There is no evidence of a decline in the striped bass population of Coos Bay. 2. The striped bass, a species introduced to the West Coast of North America, has been important as a recreational and commercial fish in Coos Bay since the late 1920s. The catch has ranged from 18,000 pounds in 1931 to 263,000 pounds in 1945. 3.A total of 4,979 angler-days and 23,851 hours were fished in 1950 and 2,563 fish were caught. The fish weighed an estimated 14,931 pounds with an average of 5.8 pounds per fish. In 1949, more than 7,170 bass were taken in the sport fishery, weighing over 61,000 pounds. 4. Two-hundred anglers were interviewed to determine their expenditures during a yearly period. It was found that they spent an average of $54.05 a year. Using this figure it was determined that the total expenditure for striped bass fishing in Coos Bay during 1950 amounted to $65,722. 5. The commercial fishery lands approximately 90,500 pounds annually; the fish average slightly over ten pounds each. In 1950, the catch was 35,400 pounds, or 3,400 fish. At a retail price of 40 to 45 cents per pound, the average annual value of the commercial catch is $38,000. The 1950 catch was valued at $15,000. 6. It was calculated that the commercial fishery in 1950 removed a maximum of 19 percent of the bass population in the fishing area at that time and within the size range selected by the gear. The total population of available fish in the bay during the fishing season was estimated to number 18,000 bass of which the commercial fishery took 3,400; this is not the total population of bass inhabiting Coos Bay. 7. Fish taken by sport fishermen ranged in size from 6 to 45 inches; fish taken in commercial gear ranged in size from 12 to 48 inches. Fish in the second, third, fourth, seventh, and eight year classes were abundant in the catches of the sport and commercial fisheries, Few fish younger than the third year class were taken by commercial gear while the second year class contributed the largest number of fish to the sport fishery in 1950. 8. Food studies indicate that fish such as herring, anchovies, viviparous perch, sand lance, and smelt are the major items in the striped bass diet. Bottom forms such as sculpins, crabs, and shrimp are found in considerable numbers throughout the year. Salmon and trout form an important part of the diet in April, May, and June when the schools of bass migrate into the Coos River spawning areas and meet the young salmon and trout migrating downstream to the sea. 9. Sex ratio studies in 1950 indicate that male bass predominate in the commercial catch. Almost three percent of all bass sampled were hermaphroditic. 10. Preliminary work on fecundity of striped bass showed the number of eggs per female to range from 900,000 in an 8.8 pound individual to 4,775,000 in a 50 pound fish.

  Citation × Citation Citation Abstract Copy Title: Tuberculosis in Pacific salmon and steelhead trout Author: Ordal, Erling Josef, 1906-, Oregon. Fish Commission, Wood, James W. Tuberculosis in salmonoid fishes was first observed in the 1952 run of fall chinook salmon (Oncorhynchus tshawytscha) returning to the Bonneville Hatchery of the Oregon Fish Commission. In the studies reported here, tuberculosis was found not only in adult spring chinook but in silver salmon (0. kisutch), blueback salmon (0. nerka), and in anadromous and resident strains of rainbow trout (Salmo gairdnerii). Advanced tuberculosis was found in salmonoid fishes held in fresh water for two years or longer, as well as in adults returning from the sea. Lesions were most frequently observed in the liver, and varied in size from small miliary tubercles to huge necrotic areas, filled with characteristic acid-fast bacilli. The typical bacilli were found in stained smears from the kidney, heart, musculature, brain, intestines, pyloric caeca, and roe of infected fish. The disease was originally observed in sexually-underdeveloped fish, and there is indication that it interferes with sexual maturation. It was found that tuberculosis in marked salmon known to be of hatchery origin was extremely high - in some cases 100 percent. Tuberculosis was absent in the small number of silver and chum salmon examined which were known to be the progeny from natural spawning. It is suggested that dissemination of the disease may be due to fish-cultural practices such as the feeding of untreated carcasses and the viscera from tuberculous fish. Since acid-fast bacilli were found in the roe of some fish, it is also suggested that the disease may be transmitted to healthy eggs during the process of fertilization. Tuberculous adult spring chinook were found less capable of surviving to maturity after they reached the spawning grounds than were non-infected fish. It is likely that tuberculosis also influences the ability of salmon to survive during earlier stages of their life history. The incidence of tuberculosis in adult spring chinook entering the Dexter holding ponds on the Middle Fork of the Willamette River in 1955 and 1956 was 8.7 and 6.1 percent, respectively. The increase in incidence to 58.8 percent in 1957 is attributed to the increased dependency of the run on artificial propagation necessitated by the construction of Lookout Point Dam. Among chinook caught in the Columbia River gill-net fishery in. February and in May 1956, 12.3 and 10.5 percent, respectively, of those examined were tuberculous. Although these are spring chinook, it is believed that hatchery reared fall chinook also entered the catch, especially during May, and may have contributed to the number of tuberculous fish taken.

  Citation × Citation Citation Abstract Copy Title: A measured delay in the migration of adult chinook salmon at Bonneville Dam on the Columbia River Author: Johnson, Donald R., Oregon. Fish Commission, Schoning, Robert W. A study was undertaken in the fall of 1948 by the Oregon Fish Commission to determine the possible presence and importance of a delay in the migration of adult chinook salmon (Oncorhynchus tshawytscha) at Bonneville Dam on the Columbia River. Approximately 650 chinook were captured, tagged, and released at the Oneonta trap 6.7 miles below Bonneville Dam and 200 were handled similarly at the dam and released above. The tag returns from Celilo Falls, the main commercial fishing area, 60 miles above Bonneville, were compared by location of tagging with regard to date of tagging and the number of days en route. The linear correlation between tagging date and days out was significant for the 39 recoveries tagged at Bonneville but not for the 35 from Oneonta. The later in the season the fish were tagged at Bonneville the more rapidly they migrated to Celilo Falls. With no adjustment for the difference in distance between the two tagging locations, the fish from Oneonta took a significant 3.4 days longer to make the trip to Celilo than the Bonneville tagged fish. When correcting for the distance difference, the delay was reduced to 3.0 or 2.6 days, either of which was still significant. Although the number of recoveries is small, all of those used are believed to be reliable and sufficient for statistical analysis. The study represents only one year's work and investigations of another year may refute or substantiate these findings.

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: Age and growth study of Tillamook Bay chum salmon (Oncorhynchus keta) Author: Henry, Kenneth A., Oregon. Fish Commission Ages were determined for 65 fish from the 1947 run and for 287 fish from the 1949 run. In 1947 the percentage composition by age was as follows: 32.3 percent 3-year-old fish, 66.2 percent 4-year-old fish, and 1.5 percent 5-year-old fish. An approximate 95 percent confidence interval for the true proportion of 4-year-old fish was 54.7 to 77.7 percent. In 1949 the percentage composition by age was as follows: 5.2 percent 3-year-old fish, 94.4 percent 4-year-old fish, and 0.4 percent 5-year-old fish. An approximate 95 percent confidence interval for the true proportion of 4-year-old fish in 1949 was 91.7 to 97.1 percent. Sex ratios during the course of the run were computed. It appeared that during the latter part of October there were significantly more males than females in the catch. During November the number of males and females tended to be nearly equal. Finally, during the first part of December there were more females than males in the catch. Growth for the earlier ages was determined by analyzing the growth of the scales and then assuming that scale growth was proportionate to fish growth throughout life. It appeared that the greatest absolute increase in length occurred in the first year of life, and that the greatest absolute increase in weight occurred during the last year of life. Length-weight equations were computed for both the males and the females. When tested by means of a t-test, these equations proved to be significantly different. These equations are: for the males W = 0.000234 [superscript L3.19370]; for the females W = 0.000430 [superscript L 3.01479]. In comparing Tillamook Bay chum salmon with chum salmon from other localities, it was observed that chums of like age decrease in average length from south to north. Tillamook Bay chums do not follow the tendency for the percentage of younger fish to decrease from south to north. Finally, there are limitations to some of the results determined in the study because of the assumptions upon which these results are based. The principal limitation is the small amount of data available. Furthermore, the following assumptions were made, and if they were not true, they could invalidate the results obtained: (1) fish length increases in direct proportion to scale growth; (2) the samples used in this study do not represent an abnormal year and do represent the populations sampled; (3) ages of these fish can be determined from their scales; and (4) that the sexes can be determined by their external characteristics.

  Citation × Citation Citation Abstract Copy Title: The salmon runs of the Columbia River in 1938 Author: Oregon. Fish Commission, Rich, Willis H. (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. Fish Commission, Rich, Willis H. (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.

The Indians at Celilo Falls catch an average of over 2,600,000 pounds of fish each year, in dip nets in a manner very much the same as used by their ancestors. 2. The bulk of the fish caught at Celilo Falls is from the upriver fall run of chinook salmon which spawns in the main Columbia, between Pasco and Rock Island Dam and on the main Snake River between Swan Falls and Marsing. 3. Until the present study, the magnitude of the Indian closed season subsistence catch, averaging 500,000 pounds annually, has been unknown. 4. Most of the fall closed season catch is dried for home use by the Indians during the year although some is sold illegally. 5. The annual average of 50,000 pounds of fish sold directly to tourists is relatively insignificant when compared to the amount sold through regular commercial channels during the open season. 6. The elimination of fixed gear in the Columbia River has increased the percentage of total fish caught by the Indians. In the case of chinooks, the Indian commercial catch increased 8.8 percent. 7. The average annual value of the total Indian catch 1947-1950 is estimated to be $700,000. Title: The Indian Dip Net Fishery at Celilo Falls on the Columbia River Author: Johnson, Donald R., Oregon.

(Donald Lynn), 1918-1979 Three factors were found to be significantly correlated with the fluctuations and trends in silver salmon production in Oregon. Logging was found to adversely affect the runs of salmon in later years. Exceptional winter floods seem to produce poor resulting runs. Low summer water flows also appear to produce lower than average runs on some rivers, while higher summer flows appear to be followed by an increase in the resultant runs. The intensity of fishing was also found to affect the subsequent productivity of the fisheries. Increases in fishing effort on the rivers studied were followed in succeeding cycles by a lower catch, and when the fishing effort declined the ensuing production of silver salmon generally increased. Other factors studied did not bear a significant relationship to the fluctuations or trends of productivity of silver salmon.
