Rivers in Bay of Fundy region in eastern North America with historical sports catches of Salmo salar. Those in white were found to be devoid of salmon juveniles in 2000 while those with a ? were not surveyed but are suspected to have only remnant populations. The rivers enclosed by the thin solid line are considered to be inner Bay rivers based on life-history and behavioural characteristics. Numbered rivers (Table 1) were sampled for the current study. The dashed line shows the ice edge c. 15000 years bp and the hatching the area which would at the time have been below sea level based on 27 Shaw et al, (2002) and J Shaw (personal communication).
