Post-drought wildfire retardant first flushes on early life stage Chinook Salmon (Oncorhynchus tshawytscha) and Rainbow Trout (O. mykiss).
Description / purpose
This project will evaluate sublethal toxicity of current-use and new fire retardants on Chinook Salmon, a listed species, as well as Rainbow Trout. Non-weathered and weathered retardants will be tested, with the intention being to generate standard LC50s and EC50s from embryo to alevin, and for weathered retardants to more closely mimic exposure a first flush-like event. Behavioral alterations, yolk sac size and potential latent effects on growth will be recorded. These data will allow managers to design approaches for fire management and prevention that have the lowest possible impact on waterways.
