Mike B,

The estimated daily and total catch of both wild and hatchery steelhead and chinook are carefully considered in conducting the fishery.

Here is some recent data:
see: http://wdfw.wa.gov/fish/crc/crc29mar04fact.pdf

Mainstem non-Indian commercial fishery impacts to listed species are estimated to be 0.332% for upriver spring chinook and 0.578% for wild winter steelhead through the March 25-26 fishing period. Total impacts to date represent 41.50% of the total upriver spring chinook impact limit (0.80%) for non-Indian commercial fisheries and 28.90% of the wild winter steelhead impact limit (2.00%) for non-Indian fisheries.

Over the eight fishing periods, a total of 8,346 chinook were kept, with 4,760 fish kept during the two 8- hour small mesh fisheries. Sampling of landed catch from the small mesh fishery showed 49% percent were upriver fish. The average size of the chinook declined from about 18 pounds to about 13 pounds.

The observed mark rate for the week of March 22 for chinook was 75% with a total observation of 317 chinook kept and 85 steelhead released for the combined March 23-24 and March 25-26 fishing periods. More information from the individual fishery observations are shown in the table below.
