Pikeminnow

Throughout the Columbia River, there have been many efforts focused on the downstream survival of salmonids (Oncorhynchus spp.).

Salmonids pass up to nine hydroelectric projects on their migrations to the ocean. As one of those measures, various agencies have implemented measures for the control of predacious northern pikeminnow (Ptychocheilus oregonensis).   
 
In 1993 Mid-Columbia PUDs jointly funded a study of predation on juvenile salmonids in the region to identify areas of northern pikeminnow abundance and areas of high predation on out-migrating juvenile salmonids. Density-index values of pikeminnow in the mid-Columbia reservoirs were as high as many reservoirs of the lower-Columbia. In 1997 Columbia Research began working with Mid-Columbia PUDs for the research and capture of northern pikeminnow. Over the past 18 years, we have been leaders of pikeminnow research and predator control projects conducted in the Mid-Columbia.
