The finale takes Gifford Pinchot's measuring stick, the greatest good for the greatest number for the longest time, seriously, flaws and all. It asks who counts in the greatest number and what the longest time means for a fishery about forty years old, a salmon culture eleven and a half thousand years old, and a warming sea. It tests nine options, gives a measured verdict, and closes where the series began.
Which wording is Pinchot's maxim differs across 1905, 1910 and 1947, and who first wrote the longest time is unsettled. Whether bycatch reductions help the runs is argued from different starting points. The verdict is a measured judgment on contested evidence, offered as the series' reading.
