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 Lake was conducted on July 21, 2022, by Index of Biological Integrity (IBI) Program 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 and seining with a 50-foot seine were completed at ten sampling stations. Nearshore sampling captured twenty species of fish including seven species that are intolerant of disturbance (i.e., Banded Killifish, Blackchin Shiner, Blacknose Shiner, Iowa Darter, Mimic Shiner, Pugnose Shiner, and Rock Bass) and none that are tolerant of disturbance. A summer trap net survey was also conducted by IBI Program staff on July 25-27, 2022. Nine nets were set along the shoreline in locations that encompassed multiple habitat types. Trap net sampling captured nine species of fish, including one that is intolerant of disturbance (i.e., Rock Bass). Bluegill comprised a majority of the catch by number and biomass. The nearshore and trap net data were combined with gill net data from a July 2020 survey to describe the fish community and provide a fish-based IBI (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., Fathead Minnow and Green Sunfish). 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 indicate 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 will be considered when the biological health of the lake is assessed during the Leech Lake River Watershed assessment process, which will be completed in coordination with MN Pollution Control Agency.
