Table 2 The probability of survival and migration speed (km/day) of day- and night-released treatments between each gate (head of tide = HoT; the intersection of the Northwest Miramichi River and the main stem of the Miramichi River = Nelson; the entrance into the Miramichi Bay = Inner Bay; the exit of the Miramichi Bay = Outer Bay; Strait of Belle Isle = SoBI) and cumulative survival from release to SoBI
