The Lower Columbia River spring chinook fishery remains slow as of Tuesday despite a rise in angler effort.
Here are some figures for this past week:
Through March 20, there have been an estimated 35,731 angler trips with 1,349 adult spring chinook kept and 343 released.
The 1,187 (88-percent) spring chinook kept were of upriver origin based upon Visual Stock Identification (VSI).
An estimated 15-percent of the 7,750 upriver catch guideline has been taken. There were also 227 steelhead kept and 221 released.
Salmon fishing effort more than doubled from the previous week with 931 boats and 514 bank anglers counted during the Saturday, March 19 aerial flight survey. However, effort is down about 40-percent from the same time last year (1,634 boats and 824 bank anglers).
