West Coast Salmon Vulnerable to Climate Change, but Some Show Resilience to Shifting Environment

Lots of reports coming from other rivers that are warmer than normal and are getting pre-spawn mortality due to heat. It's happening in Europe as well with the wild Atlantics salmons.

Moving on to the season now underway – Here’s another recent DFO quote to put things into more of a head scratching context: “As of July 22, the number of chinook salmon returning to the Skeena River is forecasted to be between 32,000 and 35,000. The amount of chinook needed to spawn sustainably is 19,000.” If the chinook escapement in 2017 was only 18,400 against a target of 19,000, why was there any fishing at all? Next, compare the July 22, 2018 test fishery index for chinook of 87.37 with the 2019 index of 68.67 for the same date. There was a conservation concern so great in 2018 that not even a single barbless hook, artificial lure only, catch and release fishery could be permitted but one year later, with 22% less chinook in the Skeena, the same sport fishery slam dunked a year earlier was okay. And, of course, the FN fishery remained unconstrained.

Silly DFO managment close everything down last year and returns were better, Open it up for most of the season this year and returns are worse. This is why people think they use a dart bord to managage
 
Resilience. Wasn't that what pa tried to teach you out back of the woodshed.
Seems nature has been doing it forever. Certainly long before ENGOs.
 
I wonder how salmon faired when the Romans were growing wine in Britain. Surprised there's any left over their
