| Remarks | 'Fathom', i.e., a unit of length equal to six feet used especially for measuring the depth of water (p. 452 in Ref. 11978). Probably referring to adult eulachon inhabiting the echo-scattering layer of the water not far from the coast. They apparently remain in the depths on their spawning migration until very close on the mouths of the rivers. Those adults that survive the spring spawning migration spend little time in freshwater. |
