DNR fish survey, 2025

Catch per net (CPUE) is the DNR survey's count per gill net or trap net set; higher means more of that species were sampled, not a fishing forecast. Top species per gear shown; where we have no verified common name for a DNR code, the code itself is shown.

A targeted survey of nearshore fish species in Shumway Lake was conducted on July 28, 2025, by Aitkin area fisheries staff. Sampling sites (N=10) were evenly spaced around the lake, and each was sampled by backpack electrofishing and seining with a 50-foot or 15-foot seine, where possible. Backpack electrofishing was completed at all 10 sampling stations, two of which were sampled via boat due to deep water, soft sediment, or dense emergent vegetation. Similarly, a 50-foot seine was used to sample 5 stations, and a 15-foot seine was used at 3 stations. Three stations were not seined due to deep water, soft sediment, or dense emergent vegetation. Nearshore sampling captured 7 species of fish including one species that is intolerant of disturbance (e.g., Iowa Darter) and zero that are tolerant of disturbance. The nearshore data were combined with trap net and gill net data from a 6/9/2025 standard survey to describe the fish community and provide a fish-based score of biotic integrity (FIBI). The FIBI score uses fish community data to quantify a lake's health, and the types of fish species present can help identify stressors that may be negatively affecting the lake environment. In Minnesota lakes, certain fish species cannot survive without clean water and a healthy habitat (e.g., Blackchin Shiner, Iowa Darter, Rock Bass), while other species are tolerant of degraded conditions (e.g., Green Sunfish, Common Carp). The FIBI score, composed of several fish community diversity and composition metrics, indicates the overall health of a lake by comparing it to expected values for a healthy lake. For additional information on the FIBI, search for "lake index of biological integrity" on the mndnr.gov web site. Results from this survey provide evidence that the fish community in Shumway Lake appears healthy as indicated by a FIBI score above the general use impairment threshold for aquatic life use determined for similar lakes. These results are similar to previous findings which indicated that Shumway Lake is fully supporting aquatic life. These survey results will be considered when the biological health of the lake is assessed during the Mississippi River-Grand Rapids watershed assessment process, which will be completed in coordination with MN Pollution Control Agency. You can help protect the fish community in Shumway Lake by preventing the spread of invasive species and minimizing environmental impacts when visiting Savana Portage state park.
