DNR fish survey, 2021

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 Gull Lake was conducted on July 12-14, 2021, 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 was completed at 24 sampling stations, but three stations were sampled from the boat due to site conditions. Similarly, a 50-foot seine was used to sample 10 stations, a 15-foot seine was used at eight stations, and site conditions prevented the use of seines at six stations. Nearshore sampling captured 16 species of fish including three species that are intolerant of disturbance (Blackchin Shiner, Iowa Darter, Rock bass) and one species that is tolerant of disturbance (Black Bullhead). The nearshore data were combined with trap net and 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 (Blackchin Shiner, Iowa Darter, and Rock Bass), while other species are tolerant of degraded conditions (Black Bullhead). 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 Gull Lake is healthy as indicated by an FIBI score above the impairment threshold for aquatic life use determined for similar lakes. These results will be considered when the biological health of the lake is assessed during the Mississippi River-Headwaters Watershed assessment process, which will be completed in coordination with MN Pollution Control Agency.
