Using acoustic telemetry to quantify potential contaminant exposure of Vermilion Rockfish (Sebastes miniatus), Hornyhead Turbot (Pleuronichthys verticalis), and White Croaker (Genyonemus lineatus) at wastewater outfalls in southern California

Contaminant Exposure Models (CEMs) were developed to predict population-level tissue contaminant concentrations in fishes by pairing sediment-bound (DDTs, PCBs) and fine-scale acoustic telemetry data from a habitat-associated species (Vermilion Rockfish, Sebastes miniatus), nomadic flatfish (Hornyhead Turbot, Pleuronichthys verticalis), benthic/midwater schooling (White Croaker, Genyonemus lineatus) tagged near wastewater outfalls southern California. Model results compared samples. The CEMs require further refinement before implementation into management efforts but may act as steppingstones help shift primary monitoring methods away the regular field collection of fish for analyses towards behavioral modeling habitat mapping. We also Kernel Density Estimates that can be used managers immediately identify regions contribute most exposure concern. Prioritizing remediation these areas are likely effective at improving health.
