Description
- Abstract: The Northern Pikeminnow Management Program (NPMP), a fishery aimed at reducing predation on juvenile salmonids by northern pikeminnow (Ptychocheilus oregonensis), was implemented for the 16th consecutive year in the mainstem Columbia and Snake rivers. We report on (1) northern pikeminnow exploitation rates, predation estimates, spaghetti tag loss rates, and age validation work; (2) population parameters of northern pikeminnow, smallmouth bass (Micropterus dolomieu), and walleye (Sander vitreus) in The Dalles and John Day reservoirs, and (3) possible compensatory responses by these species.
