DNR fish survey, 2024

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 June 25-26, 2024 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. Backpack electrofishing was completed at ten sampling stations. Similarly, a 50-foot seine was used to sample nine stations, and a 15-foot seine was used at one station. Nearshore sampling captured 17 species of fish including six species that are intolerant of disturbance (i.e. Blackchin Shiner, Blacknose Shiner, Iowa Darter, Least Darter, Rock Bass, and Smallmouth Bass) and no species that are tolerant of disturbance. A concurrent summer trap net survey was also conducted by IBI Program staff. Nine trap nets were set along the shoreline in locations that encompassed multiple habitat types. Trap net sampling captured seven species of fish. Bluegill and Yellow Bullhead comprised a majority of the catch by number and by biomass. The trap net catch was light overall. The nearshore and trap net were combined with gill net data from a July 2023 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, Least 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 MNDNR FIBI general use threshold determined for similar lakes. The survey 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. You can help protect the fish community in Long Lake by reducing runoff, maintaining natural shorelines, and preventing the spread of invasive species.
