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 North Twin Lake was conducted August 19th - 21st, 2024, by Detroit Lakes Fisheries Staff. Data was collected from 14 sampling stations evenly spaced around the lake. All stations were sampled with a backpack electrofishing unit, 6 were sampled with a 50-foot seine and 1 station was sampled with a 15-foot seine. Six stations were not sampled with a seine because of dense vegetation, water being too deep or muck being too thick to effectively use a seine. Nearshore sampling captured 22 species of native fish, which included five species that are intolerant of disturbance (Banded Killifish, Blackchin Shiner, Blacknose Shiner, Iowa Darter, and Rock Bass) and two species that are tolerant of disturbance (Black Bullhead and Green Sunfish). The three most common species captured during the nearshore survey in order of abundance were: Largemouth Bass, Bluegill, and Bluntnose Minnow. The nearshore fish survey data was combined with the standard survey data from August 2023 to describe the fish community and provide a Fish-based Index of Biotic Integrity (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., Black Bullhead, 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. Data from this survey will contribute biological information about the health of the fish community to a watershed assessment process in coordination with MN Pollution Control Agency. North Twin Lake is located in the Wild Rice River Watershed.
