In 2011-2012 the Washington Department of Fish and Wildlife (WDFW) conducted a Puget Sound-wide assessment of toxic contaminants in Dungeness crab (Metacarcinus magister) and spot prawn (Pandalus platyceros); its purpose was to (a) evaluate the geographic extent and magnitude of toxic contaminants in these two crustacean species in Puget Sound and (b) to provide contaminant data to Washington State Department of Health (DOH) to conduct a human health risk assessment. The study was designed to sample animals typically taken in fisheries, across areas typically fished, and using typical sport-fishery gear. In addition, within each species, we sought to hold potentially confounding biological covariates (such as size and sex) constant across sampling areas. Data summaries herein are focused on a comparison of contaminant concentrations in crustacean tissues across sampling areas in Puget Sound.
