The Southwest Alaska Network (SWAN) is part of the National Park Service (NPS) Inventory & Monitoring Division, which was created in 1998 to quantify the status and trends of select indicators or “vital signs.” One of the vital signs monitored by SWAN is resident lake fish (i.e., non-migratory freshwater species). Resident lake fish are key indicators of ecosystem health due to their continuous exposure to lake waters, which integrate conditions from the surrounding land and air (Schindler 2009). For this reason, and also because resident lake fish are important for subsistence and recreational fishing in Alaska, it is crucial to better understand their contamination levels and sources.
