Baseline fish health information on pallid sturgeon and bull trout or appropriate surrogate species (shovelnose sturgeon, cutthroat trout, mountain whitefish) in critical habitats with elevated risks of oil spills. Shovelnose sturgeon (Scaphirhynchus platorynchus) were collected in three locations near the confluence of the Missouri and Yellowstone Rivers and cutthroat trout (Oncorhynchus clarki lewisi) and mountain whitefish (Prosopium williamsoni) were collected from critical bull trout habitat along the Middle Fork of the Flathead River. Fish health metrics evaluated included gene expression/enzyme induction in various tissues, differential changes in white blood cells, polycyclic aromatic hydrocarbon bile metabolites,...

We used mesocosm experiments to compare coarse filter-large water volume samples (hereafter large volume filter samples) vs. fine filter-small water volume samples (hereafter small volume filter samples) for detection and quantification of rainbow trout (Oncorhynchus mykiss). We report the quantity of rainbow trout DNA detected using large and small water volume sampling approaches under control (no fish) and treatment (1 fish) conditions.
