Treaty rights allow tribal members to ..., 5 Oct 2013 [cached]
Treaty rights allow tribal members to keep such steelhead, but "tribes have to count all the steelhead caught, and once they get to the limit, they stop all chinook fishing," said Kathryn Kostow, a fish analyst for the Columbia River with the Oregon Department of Fish and Wildlife.
While it's more fun to scale up a season in response to fish exceeding expectations, Kostow said the management adapts either way to keep harvest at healthy levels for the fish populations.
Kostow said that it's not uncommon for a good chinook year to coincide with a bad coho year because the fish face very different environmental conditions. They migrate out during different seasons and then live and feed in different parts of the ocean.
The low steelhead and coho numbers aren't that alarming, Kostow said. She said that some of the low numbers might be because the steelhead from Idaho hatcheries are coming back much smaller than usual, and since catch limits and counts are based on fish size, they aren't being counted.
"Somewhere in their life cycle, that group of fish did not grow as big as they should have," said Kostow.
They may never have an exact answer why. But, she added, it would be nice to know why the chinook run was so good, so they can do it again.

"The (upriver spring Chinook) run is actually not a huge forecast, but it is an above-average one when you look at all our data going back to 1980," said Kathryn Kostow of Oregon Fish and Wildlife and chairman of the Columbia River Technical Advisory Committee.
