The commercial fisheries took in salmon by the hundreds of thousands per year in the lower reaches of the Columbia in the late 19th and early 20th centuries. Early methods incorporated those used by natives including the use of fish traps, or weirs, but also came to include the use of large gill and seine nets and both stationary and floating fish wheels. The canneries themselves were located near the most plentiful source of fish near the mouth of the Columbia as the map at right suggests.

These early canneries, like the first at Eagle Cliff, were labor intensive operations, often taking advantage of the availability of cheap Chinese contract labor. These workers were the first to be displaced as mechanization in the form of equipment like this fish cleaning machine were brought into the canneries.

Oregon salmon from the Columbia was shipped world-wide, although by far the largest portion went to Great Britain for shipment throughout the British Empire.² Warehouses of fish ready for shipment were literally filled to the gills during the height of the season.

Salmon production went from zero in 1866 to a peak of over 600,000 forty eight pound cases in 1883. The graph below provides a picture of production in the Columbia canneries from 1866 to 1928 during the industries most profitable years and as it leveled off during the depression of the 1930s:

How many were there in 1892 according to the data in the map? 2) Most of the canneries on the Columbia were within how many miles of the mouth of the river? Identify the cannery furthest upstream and how far it is from the Pacific. 3) Click on the Salmon Imports bookmark to switch to a world view. Change the symbols so that the import data in the map uses colors to display the data in 5 quantiles (groups of roughly equal number). Describe the world wide pattern of salmon distribution that you see. Where do the largest exports of salmon go from the United States and what do these countries have in common? 4) Compare the graphs for chinook, sockeye, and steelhead. Why do you suppose sockeye and steelhead began to be canned beginning in 1889? 5) Make two generalizations about the change from 1883 to 1928 in the numbers of the three species of salmon shown in the graph. 6) Assuming a price of about $0.13 per pound, what was the approximate value of the two pound cans of salmon pictured in this Astoria warehouse? 7) Study the pictures of the fishing methods used to supply the canneries, do any additional research needed about each method, and compare and contrast each approach in terms of the labor involved and its productivity.
