and that about 80–100 linear kilometers, or 50-60 miles of spawning coastline would produce
80% fidelity.
The historic spawning coastline for Lynn Canal Herring extended outside of Lynn Canal
into Icy Strait. This spawning area was likely at least 50 miles of coastline before historic
overfishing reduced the population (Rounsefell 1931, Rounsefell and Dahlgren 1936, Skud
1959) (See Figure 5). In 1956-1957, Lynn Canal Herring spawned on 28.1 nautical miles (52
km) of coastline (ADFG 2004), but this was likely a reduced population. Thus, based Hay et al.
(2001a) and evidence from Carlson (1980), Lynn Canal Herring do not intermingle with other
herring stocks and exhibit strong site fidelity for Lynn Canal and the immediate vicinity.
