Allozyme markers were used to investigate the spatial boundaries of the non‐anadromous Atlantic salmon population of Little Gull Lake, Eastern Canada. Mixed year class samples of juvenile salmon were analysed from inlet streams, upstream lakes, the outlet river and sites downstream. No evidence was found that individuals from the Lake's non‐anadromous population were present in these samples, strongly suggesting that the non‐anadromous population is confined to the lake and has a lacustrine spawning habit.
