Resurrecting this this thread as an example of how far things can go south in a matter of only TWO chinook generations.

The BigBoy is likely a Skeena king originating from Kitsumkalum stock. Those fish are gone... gone... GONE.

This is from a report I copy/pasted from BC...

Skeena chinook in 2024 saw what may be their worst return on record. This continues an almost 15-year downward trend. It is interesting how Alaskan and northern B.C. chinook abundance has diverged from southern B.C. and the U.S. states of Washington and Oregon, which have seen improving abundance in the last couple of years. This is not unusual. We have seen this in the past. A decline in chinook abundance often begins in their southern range and moves north over a decade or more.
Recovery also usually begins in the south and gradually moves north in response to changes in their marine environment. Will chinook abundance in the north eventually improve as many southern chinook populations have? All we can do is hope, while protecting the habitat and getting as many as possible back to spawn every year.
