Pikeminnow catches dropped by more than 1,700 last week over the previous one, with 7,148 brought to stations on the Columbia and Snake Rivers July 17-23.
That figure is also less than half of what it was a month ago but reflective of the typical seasonal lull in the fishery that pays anglers to remove the native species that preys on young salmon and steelhead in the Columbia hydropower system.
For the third straight week, Boyer Park on the Snake below Lower Granite Dam retained its spot as most productive, with a haul of 1,771 qualifying fish,
That’s nearly 1,000 more than the second best station, Greenbelt, also on the Snake, where 787 were brought in, according to the latest figures from program manager Eric Winther.
Coming in third was The Dalles, with 675, then Cathlamet, on the Lower Columbia, with 622.
Giles French had the highest catch per angler, with 15.2 for the 38 participants, followed by 9.3 at Cascade Locks and 8.9 at Boyer Park.
The overall average per angler was 5.8 pikeminnow for 1,235 participants, down about a fish a fisherman over the previous week.
Eight specially tagged pikeminnow were turned in last week, up from five the week before, with three at Columbia Point, and one each at Cathlamet, Gleason, Washougal, The Dalles and Greenbelt.
All totaled, 121,014 qualifying pikeminnow have been removed from the Columbia and Snake since the start of season May 1.
The Dalles has been most productive, with 43,613, followed by Columbia Point at 14,681 and Boyer Park 14,054.
Average catch is 6.9, with a range from 11.0 at The Dalles to 1.5 at Willow Grove and Umatilla.
Just over 200 tagged fish have been turned in.
Effort is 17,524 on the season.
The sport reward program pays anglers from $5 to $8 per pikeminnow, with tagged ones worth $500.
