Short description | Reduce predation on juvenile salmonids by implementing fisheries to harvest northern Pikeminnow in the mainstem Columbia and Snake rivers. Monitor effects of fisheries on predation by northern Pikeminnow and other resident fish. |
Target species | |
Year | Accomplishment |
1993 |
Initial index of northern Pikeminnow predation on juvenile salmonids completed. Predation found to be significant throughout the lower Columbia and Snake rivers. Results published in peer-review journals. |

1993 |
Sport-reward and dam-angling fisheries found to be successful in removing large numbers of northern Pikeminnow. Annual explitaion rates exceeded the minimum goal of 10%. Results published in peer-review journals. |

1997 |
Confirmation that compensation by northern Pikeminnow and other resident fish predators has not occurred as a result of Pikeminnow removals. No trends in consumption, growth, or reproduction observed. Results published in peer-review journals. |

1999 |
Confirmation that compensation by northern Pikeminnow and other resident fish predators has not occurred as a result of Pikeminnow removals. No trends in consumption, growth, or reproduction observed. |
1999 |
Predation on juvenile salmonids by northern Pikeminnow reduced from pre-program levels. Modeling results (supported by empirical evidence) indicated that annual reduction in predation is maintain at about 25%. |

Changes result from elimination of some components of the dam angling task and site-specific fishing by Columbia River tribes and the Columbia River Intertribal Fish Commission. In addition, cost efficiencies in the running of registration/check stations helped offset some of the inflationary costs.
Some dam angling and site-specific fisheries are not currently productive in areas where they had been in the past..
