For those interested in a technical read, this is the science advice document that was developed in a big hurry this winter to inform fishery manager decision making re: acceptable Interior Fraser coho impacts . When I say "in a hurry", I am not commenting on the quality of the work (it's good), more on the priority that this work was given to ensure that sound scientific advice was available to base decisions on.

Have a look and see if you agree with DFO managers interpretation of the data.

Spoiler alert: Figure 3b sounds the most alarms for me. We aren't out of the woods yet.....

Too bad a few managers couldn't be reincarnated into interior coho.

Typical..
Instead of saying:
"The large commercial openings that we are hoping for sockeye will KILL thousands of endangered interior cohos and possibly eradicate wild coho populations from several creeks/rivers"

You say:
"In the current low productivity period, ... if exploitation rate is raised to 30%, the probability of achieving the short term recovery objective within 1, 2 or 3 generations ... decrease to 0.51, 0.52 and 0.50. The probability of meeting the longer term objective is
low regardless of exploitation."

Then:
The decision of opening the commercial fishing is easier to make no?
Because you don't eradicate for say, you just "decrease the short term recovery objective to 0.5"
