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 Jack Lake which is located wholly within the Leech Lake Band of Ojibwe Nation, was conducted August 20-21, 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, where possible. Backpack electrofishing was completed at ten sampling stations. Similarly, a 50-foot seine was used to sample four stations, and a 15-foot seine was used at three stations. Three stations were not seined due to soft mucky substrate and dense wild rice, water lilies, and/or chara that prevented wading. Nearshore sampling captured 17 species of fish including 7 species that are intolerant of disturbance (i.e., Banded Killifish, Blackchin Shiner, Blacknose Shiner, Iowa Darter, Least Darter, Northern Sunfish, and Rock 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 eight species of fish, including one that is intolerant of disturbance (i.e., Rock Bass). Bluegill comprised a majority of the catch by number, whereas Northern Pike and Bluegill 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 June 2018 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 Cisco), 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 Jack Lake is healthy as indicated by an FIBI score that exceeds the MNDNR FIBI exceptional use threshold determined for similar lakes. These results are similar to previous findings regarding the biological health of Jack Lake. You can help…
