Description
This project studied the seasonal movements and habitat preferences of northern pike in Whiskey and Hewitt lakes, removed pike to reduce predation on salmonids, and studied the effects of NEPTUN barrier technology on pike movements and electricity on the mortality of pike embryos and larvae.
Project Benefit
The utilization of electrical barriers tested in this project may assist with eliminating the widespread dominance and habitat expansion of northern pike. Population estimates and knowledge of northern pike habitat and movements will benefit known historical salmon lakes through targeted suppression efforts allowing salmon smolt production to return to previous levels.

| Key issues addressed by life history research | |
| This project used jaws, scales, and otoliths to age invasive northern pike; estimated their population and size structure; reduced the population; tracked their movements and habitat preferences; and tested mechanisms for suppression. |
