The literature is out there. It is just being ignored.
The literature is out there on a lot of stuff. I just took a look at the NOAA evaluation of the PS Chinook harvest RMP. For all practical purposes NOAA's Salmon
Management Division ignores the evidence of loss of productivity caused by hatchery fish spawning naturally, while including hatchery fish spawning naturally (and their offspring) in estimates of escapement abundance and trends. They even ignore the conclusions (actually, even worse, they mis-represent the conclusions) of NOAA's own independent Recovery Implementation Science Team (RIST) that says that you have to deal with having large proportions of hatchery spawners if you're going to have recovery. You kind of wonder if anybody in that agency is ever going to step up and be in charge.
It seems to me, that despite evidence to the contrary, the salmon managers think that someday they might return to the rock star status they once had and be in charge of a bunch of stuff again. Sadly, unless they start to address all the factors for decline and the needs of viable salmon populations, that just simply is not going to happen. I just wish they would come to that conclusion as well, so that other folks could get on with it.
