The Bonneville Power Administration says substantial reward increases for the Northern Pikeminnow Sport Reward Fishery have been put in place for the 2022 season.   Opening day for the northern pikeminnow sport reward season is May 1 and this year anglers will earn $6, $8 or $10 – up from $5, $6 and $8 – for each pikeminnow that is at least nine inches long.   It’s the first reward increase since 2015.  The more fish caught, the more each pikeminnow is worth.  Specially tagged northern pikeminnow released by state fish and wildlife biologists into the Columbia and Snake rivers are each worth $200 to $500.  In addition to increasing reward amounts, program managers are making it easier to participate.  Online registration and an app are expected to debut early in the 2022 season, for more information go to pikeminnow.org.  Northern pikeminnow consume millions of young salmon and steelhead each year.  Since 1990, anglers paid through the program have removed nearly 5 million pikeminnow from the Columbia and Snake rivers.
