"Jacking what?????". They have found that some really rapidly growing Chinook males spawn before smolting. They are the only Pacific salmon, to my knowledge , that actually survive the first spawning and spawn again a year later.

It seems that we should have learned (just how many times are you gonna hit that thumb with that hammer?) that all the technological fixes don't, haven't worked for actual salmon recovery. They do allow us to not deal with the real problem. Like yelling "emails, Benghazi" it diverts us from dealing with the real problems because they are very difficult and the solutions are painful.
