Salmon in 1991: Snake River sockeye ES · 599
[598] [read-salmon-12-198] In 1991, the field log for Salmon is headed “Snake River sockeye ES.” The figure kept beside that heading is 1991. It is a count or a date from the work, not a rank of the species’ worth. A zoo birthday card does not replace the log. Some Pacific stocks remain productive; many Atlantic and southern-US Chinook runs are endangered or extirpated behind dams.
After 2011-14, sediment flushed and salmon recolonised reaches above the old dams faster than some models feared -- a rare full-height teardown. Are hatcheries a solution or a delay? They keep harvest numbers up and can dilute wild fitness. The argument is now about proportions, not existence.
Why are Atlantic salmon a different politics? Wild S. salar collapsed in much of Europe and New England. Farmed Atlantic salmon in net pens are a separate industry with sea-louse and escape files. Many Alaska runs are still large and limited-entry managed. That success is not transferable to a heavily dammed Columbia without the same habitat.
Olfactory imprinting on natal water plus celestial and magnetic cues. A ladder that smells wrong is a closed door. Did Boldt (1974) change more than courtrooms? US v. Washington affirmed treaty harvest shares for tribes. Allocation, not biology, became the daily salmon fight in Puget Sound.
Keep 1991, “Snake River sockeye ES,” and 1991 together or the note on Salmon stops being that year’s record.1991
