Environmental mercury contamination is a widespread, global threat to aquatic resources and human health. Fish can accumulate high levels of mercury, especially the more toxic methylmercury, and represent the primary vector of exposure to human consumers. Many communities relying on subsistence fishing as a primary protein source are particularly at risk, especially in areas with limited monitoring activity where the necessary information to communicate risk is unavailable. Widespread fish monitoring programs are costly to implement and maintain, commonly resulting in a limited focus on areas with know contamination or the greatest recreational fishing pressure. Other biosentinels, such as dragonfly larvae, can mitigate many of these issues and may be effective proxies for fish sampling; however, the relationships between biosentinel and fish mercury concentrations are poorly resolved. We assessed mercury impairment in 20 waterbodies from Congaree National Park, SC, USA, which in known to have elevated mercury and supports significant subsistence fishing activity but currently has limited information for communicating risk to local anglers. We co-collected dragonfly larvae and fishes to better understand the relationships between these metrics. This presentation will provide refined fish-dragonfly mercury relationships for four taxonomic groups of fish frequently consumed by local anglers: Largemouth Bass (Micropterus nigricans/ salmoides), sunfishes (Lepomis spp.), catfishes (Ictaluridae), and Bowfin (Amia calva). Such taxa-specific relationships provide resource managers the details necessary to effectively evaluate mercury exposure risk to local anglers while minimizing the financial and logistical burden of data collection.
