Enzyme activity - Evaluating the impacts of pesticides on ESA-listed salmon and their habitats

Long-running science support for the agency (Office of Protected Resources, others) related to the use of modern pesticides throughout the United States as a limiting factor for endangered species conservation and recovery. This work is currently supporting several national ESA Biological Opinions, and is under review by the National Academy of Sciences. The NAS panel recommendations are expected in the summer of 2013, and these will guide additional research in FY14 and beyond.

Samples run in triplicate: These data were collected and processed in accordance with established protocols and best practices under the direction of the project’s Principal Investigator. Contact the dataset Data Manager for full QA/QC methodology.

No Delay

The Northwest Fisheries Science Center facilitates backup and recovery of all data and IT components which are managed by IT Operations through the capture of static (point-in-time) backup data to physical media. Once data is captured to physical media (every 1-3 days), a duplicate is made and routinely (weekly) transported to an offsite archive facility where it is maintained throughout the data's applicable life-cycle.

Fish tissues were analyzed for acetylcholinesterase enzyme activity.
