Catfish’s home ranges over 15 october–15 March in winters 2017 to 2020. Home range 95% is filled in pale grey and delineated with a thin dotted line; home range 50% is delineated with a bold dotted line. The contour of the aggregation zone is colored in orange, blue, red and green, respectively in 2017 (a), 2018 (b), 2019 (c) and 2020 (d). The aggregation zone corresponds to the utilization distribution with probability level of 35% (21 352 m2 area), 50% (32 141 m2 area), 30% (44,050 m2 area) and 40% (26,035 m2 area), respectively in 2017, 2018, 2019 and 2020. The aggregation zone exactly matches with the home range 50% in 2018. The total area of the lake is 1,036,888 m2. The grey dots symbolize the locations 5, 38 and 42 where hourly temperature was measured. The points 5 and 38 are close or inside the aggregation zone and the point 42 is the deepest point of the lake which stands as a reference point
