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 Long (NE) Lake, was conducted on July 15th, 2025, by Area Fisheries staff. Sampling sites 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 10 sampling stations. Similarly, a 50-foot seine was used to sample 2 stations, and a 15-foot seine was used at 3 stations. Five stations were not seined due to dense vegetation and depth. Nearshore sampling captured 22 species of fish including 5 species that are intolerant of disturbance (i.e., Banded Killifish and Iowa Darter) and 1 that are tolerant of disturbance (i.e., Green Sunfish). A concurrent summer trap net survey was also conducted by Area Fisheries Sta. Nine trap nets were set along the shoreline in locations that encompassed multiple habitat types. Trap net sampling captured 11 species of fish, including zero that is intolerant of disturbance. Bluegill and Yellow Bullhead comprised a majority of the catch by number, whereas Yellow Bullhead and Bluegill again comprised a majority by biomass. The trap net catch was light overall. The nearshore and trap net were combined with gill net data from a August 2025 survey to describe the fish community and provide a fish- based (FIBI) score. The FIBI uses fish community data to measure a lake's health and the types of fish species present can help identify any 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, and Rock Bass), while other species are tolerant of degraded conditions (e.g., Green Sunfish and 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 what is expected for a healthy lake. For additional information on the FIBI search for "lake index of biological integrity" on the mndnr.gov website. Results from this survey provide evidence that the fish community in Long Lake is healthy as indicated by an FIBI score that exceeds the exceptional use threshold determined for similar lakes. These results are similar to previous findings, which indicated that Long Lake is fully supporting aquatic life. The survey results will be considered when the biological health of the lake is assessed during the Mississippi River -Sartell watershed assessment process, which will be completed in coordination with MN Pollution Control Agency.…
