F I G U R E 5 (a) Movements (along latitude) of anadromous Arctic char (Salvelinus alpinus) implanted with an abdominal tag but not with an oviduct tag. Sedentary behavior during the presumed spawning period (gray shading) suggests spawning for 6211 and 6227 (Inuhuktok), and 6193 (Nakyulik), shown in blue; (b, c) mapped positions of these inferred spawning fish during a 3-week period (blue points) and detected spawning locations from oviduct tags (pink points) shown in Figure 2 are also shown for comparison. Areas of spawning observed by Inuit fisher are shown on the maps for comparison (orange polygons). The spawning act was not clearly identified in the "possible spawning" site identified in Inuhuktok, but aggregation of Arctic char in spawning color was suggesting a spawning site.
