History .

Fishing was in full swing in the 1800's on the CR in the NW territories. Before the time WA entered into the union there was already cries of more fish being caught than could be replenished from spawning grounds. WA became a state in 1889. The beginning of building of hatcheries to supplement the runs occurred before 1900.

The CR fish were only intercepted terminally, with no dams, plenty of habitat ,water quality, no urban sprawl.

I'm not here to dismiss your top 5 list would be nice to see again, but the documented tonnage taken from the CR was over fishing according to the people of that time and also F&W starting 1889 and supplemented with hatchery fish.


Continuing on..;

A few cut and pastes from history pages;

“In the mid-1800s, stocks of salmon on the Columbia River began to diminish quickly. Scientists advocated a hatchery program in the 1870s,
Canneries
Fresh, salted, dried, and smoked—these were the options for preserving and eating salmon before the spread of canning technology in the mid-1800s. William Hume, his brother George, and their friend Andrew Hapgood established the first cannery on the Columbia River in 1866.
Other companies followed, as did fishermen, laborers, and merchants. By 1883, there were 55 canneries on the Columbia, and the Pacific salmon industry was among the most valuable fisheries in the world. That year, the best ever, the canneries piled up 630,000 cases of salmon—30.2 million one-pound cans.
Other immigrants, a large percentage of them from Scandinavian countries and the Balkans, caught most of the fish processed in the canneries. Cannery owners rented small boats and nets to the fishermen. The two-man boats, powered by sail and oar, dragged long gillnets -- generally at night so the salmon wouldn't see them -- on which the salmon were caught by their gills. Historian Richard White notes that while one gillnet boat's catch was small, the fleet of nearly 2,000 boats "covered the river below Portland from May to August. Their nets formed a vast floating barrier to salmon -- 545 miles long by the late 1880s if connected and stretched end to end" (White, 40).”

Scientists advocating hatcheries in 1870's because of dwindling stocks and the largest catch was caught in 1883. Sound familiar? It sounds like overfishing to me then and similar circumstances today.

The overfished depleting CR stocks were only fished and caught in the mid 1800’s from the CR. Unlike their ancestors of today running the WA,BC and AK gauntlet before returning to the CR.

Because of this gauntlet only small percentages of PS Chinook are returning to their streams to spawn today to keep with this threads statewide concerns of CR,OP,PS and GH.


Continuing on...

The guantlet exists and here is an example from just one hatchery in PS where 89.61% of chinook where caught in BC/AK.
