200755000 - Toxics as a limiting factor for salmon recovery throughout the Columbia River Basin: understanding the enhanced toxicity of pesticide mixtures

Sponsor: Northwest Fisheries Science Center

Short description: Evaluate the extent that exposure to environmental levels of pesticide mixtures impacts neurological function as well as swimming and feeding behavior of juvenile salmon.

Location: Mainstem/Systemwide province, Systemwide subbasin

Budgets: FY08: $162,493 | FY09: $36,751

Primary species:
Anadromous: Coho: Unspecified Population


ObjectiveDescriptionSubbasin planStrategies
Evaluate impacts of pesticide mixtures on salmon. Determine the changes in neurological function as well as swimming and feeding behaviors exhibited by juvenile coho salmon following exposure to pesticide mixtures at concentrations routinely measured in the Columbia River Basin. (None) This biological objective addresses the critical management uncertainty posed by the presence of pesticides, a major class of toxics, in salmon habitat. Toxics were identified in the Columbia River Basin Research Plan as an emerging issue of concern.
