Impacts of climate change on pesticide bioavailability and sublethal effects on juvenile Chinook salmon in the Delta: Potential benefits of floodplain rearing

Description / purpose

The Project will include field studies to estimate loadings and bioavailability of pesticides, concentrations of pesticide residues in salmonid prey, and the trophic basis of juvenile Chinook salmon growth (benthic vs. pelagic food web pathways) and how each of these differ between floodplain and river channel habitats in the Delta. Data from the field studies will inform development of laboratory studies that will assess the potential effects of exposure to environmentally-relevant pesticide types and concentrations in prey on swimming performance, olfaction and neuroendocrinology of juvenile Chinook salmon. Laboratory studies will also evaluate how water temperature (including increased water temperatures predicted with climate change) influences these sub-lethal effects of pesticides on juvenile salmon.
