History & Status of the Fishery
A targeted survey of nearshore fish species in Roy Lake, which lies within the boundaries of the White Earth Reservation, was conducted on July 17-18, 2023 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 seine, where possible. Backpack electrofishing was completed at all 14 sampling stations, but four stations were sampled from the boat due to site conditions. Similarly, a 50-foot seine was used to sample eight stations, a 15-foot seine was used to sample two stations, and site conditions prevented the use of seines at four stations. Nearshore sampling captured 13 species of fish including two species that are intolerant of disturbance (i.e., Blackchin Shiner and Iowa Darter) and one species that is tolerant of disturbance (i.e., Green Sunfish).
The nearshore data was combined with gill net and trap net data from a July 2022 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., 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.
